The Reason Why Use of Hydrogen for Energy Backup, vs Batteries, is a No Brainer
ChatGPT tells most of this one
Inspired by the below a story of Enrique Dans
Don’t get me wrong, I like Enrique’s story, but it goes off track a little by stating batteries are the way to go, when hydrogen is in a different league, offering beneficial capability which is fundamentally not possible with batteries.
Notice the links Enrique uses to appear to validate this assertion, do not talk about the specific case of batteries, only rare elements used in things other than batteries, so those links prove nothing (Sorry Enrique).
Honestly, we should notice there is a commercial drive, towards profit, which advertises batteries whilst trashing hydrogen, even in academic discussions, those discussions are coloured by the ambition to profit
We should not make the profit blinkered mistake of thinking batteries are ok when they absolutely are not. The cost in Lithium, and by Lithium to Earth, and to people, is huge, and is actually just more misery by extraction, negating any benefits we might perceive by stopping oil
There might be theoretically enough Lithium in Earth to do the whole job, but the cost, in terms of Earth, and humanity, including kids working in mines, and actually perpetuation of the stupid system of profit that keeps us tied into all extraction, and actually modern slavery as we might define it, is incalculable.
Do we really think we can sustain that, whilst surviving all the other disasters looming already from extraction associated with fossil fuels?
Firstly a simple, unarguable, fundamental difference, between hydrogen and batteries, is that batteries require materials per KWh of energy stored, to be extracted from Earth. In the case of Lithium, this is around a kg per 100 Watt-hours. That is in a completely different ballpark, from the quantities of trace elements needed in the manufacture of a solar panel, or a diaphragm of a fuel cell or electrolyser, or actually any other electronic component, where materials are not part of the energy storage mechanism. None of the latter are required per KWhr of energy stored or throughput, only batteries require any quantity of mass (Kgs!) of rare and/or toxic materials per KWhr of energy stored.
We seem to have some trouble separating out materials requirements from energy requirements, maybe because historically we’ve always thought of energy as materials extracted from Earth. A battery conceptually is a kind of extension of that, we might say that lithium is like a kind of rechargeable fuel.
But Hydrogen is completely different. In the case of hydrogen, we are taking energy, and converting it itself, directly to the molecules of the energy carrying part of hydrogen itself. In other words, we are creating the fuel, not just recharging fuel extracted from Earth.
Batteries, keep us tied into extraction, whereas hydrogen does not, right?
OK on to the nitty gritty, there follows a dialog with ChatGPT, where we talk some numbers, to show the relative feasibility of batteries vs hydrogen.
Notice the side benefit of water circulation and filtration identified at the end. This does not exist with batteries. Further, air flight by batteries is really not a good idea, I can tell you this as someone tasked with designing aircraft in my time, batteries just can’t provide the same power to weight ratios, that air flight has become accustomed to, in the fossil fueled years, whereas hydrogen can. Check out hydrogen on the Rolls Royce Aero site if you need any reassurance there. Finally, see also (“Solein”), for a further unexpected benefit of hydrogen. I wanted to get to discussing these final points with ChatGPT, but it blew up in this thread before we got there.
Hey-ho, here it is:
Hello ChatGPT
ChatGPT
Hello! How can I assist you today?
User
I would like to make an estimate of the total amount of lithium needed worst case for the batteries that would be needed for the energy backup purposes of humanity, if the world was solar powered
ChatGPT
Estimating the total amount of lithium needed for batteries used in solar-powered energy backup purposes for all of humanity is a complex task and involves several variables. However, I can provide you with a rough estimation based on certain assumptions.
To estimate the total amount of lithium required, we need to consider the following factors:
Global Energy Consumption: According to the International Energy Agency (IEA), the global electricity consumption in 2020 was approximately 23,000 terawatt-hours (TWh).
Solar Power Penetration: Let’s assume that solar power can provide 50% of the global electricity consumption, which would require 11,500 TWh of solar energy annually.
Battery Capacity: Assuming an average battery capacity of 100 watt-hours per kilogram (Wh/kg) of lithium, we can calculate the required lithium amount.
Battery Efficiency and Days of Backup: We need to consider the battery efficiency and the number of days of backup required. Let’s assume a battery efficiency of 90% and a backup period of three days.
Now, let’s perform the calculation:
Total Lithium Required = (11,500 TWh * 1,000,000,000 Wh/TWh) / (100 Wh/kg * 0.9 * 3 days)
Calculating this, we get:
Total Lithium Required ≈ 427,777,778 kg ≈ 428,000 metric tons
Please note that this estimation assumes uniform energy consumption, battery capacity, and solar power penetration across the globe, which may not be the case. Additionally, technological advancements and the availability of alternative battery chemistries can influence these estimates. Therefore, consider this estimation as a rough approximation rather than an exact value.
User
If we were required to be solely solar powered, how would that affect the estimate above?
ChatGPT
If we consider a scenario where the entire world is solely powered by solar energy, the estimate for the total amount of lithium required for energy backup purposes would be significantly higher. This is because we would need to account for the entire global energy consumption, rather than just a portion of it.
To provide a revised estimation, we would need to consider the following factors:
Global Energy Consumption: As mentioned earlier, the global electricity consumption in 2020 was approximately 23,000 terawatt-hours (TWh).
Battery Capacity: Assuming the same average battery capacity of 100 watt-hours per kilogram (Wh/kg) of lithium.
Battery Efficiency and Days of Backup: Using the same assumptions of a battery efficiency of 90% and a backup period of three days.
Revised Calculation:
Total Lithium Required = (23,000 TWh * 1,000,000,000 Wh/TWh) / (100 Wh/kg * 0.9 * 3 days)
Calculating this, we get:
Total Lithium Required ≈ 854,444,444 kg ≈ 854,000 metric tons
In this scenario, the estimated total amount of lithium required for energy backup purposes would be approximately 854,000 metric tons. This is roughly twice the estimate provided earlier, indicating a significantly higher lithium demand when considering the entire global energy consumption for solar power backup.
User
Does this include energy use currently by fossil fuels, or does above only consider electricity?
ChatGPT
Apologies for the oversight. The estimate provided earlier only considers electricity consumption. It does not include the energy use currently fulfilled by fossil fuels in sectors such as transportation, heating, and industrial processes.
If we were to consider the complete energy consumption, including the energy currently fulfilled by fossil fuels, the lithium requirement for energy backup purposes would be even higher. This is because the estimate would need to account for the additional energy demand and storage requirements associated with sectors beyond electricity generation.
Obtaining an accurate estimate for the total lithium needed in such a scenario would require detailed data on energy consumption in all sectors and their respective backup requirements. Unfortunately, I don’t have access to real-time data to provide a precise estimation considering all energy sectors.
It’s worth noting that the transition to a solely solar-powered world would involve various factors, including improvements in energy efficiency, the development of alternative energy storage technologies, and changes in energy consumption patterns. These factors can influence the overall lithium demand in the future.
User
Does IEA provide figures for consumption of all energy?
ChatGPT
Yes, the International Energy Agency (IEA) provides figures and analysis for the consumption of all energy, not just electricity. The IEA is an autonomous agency that works to promote clean, reliable, and affordable energy for its member countries and provides comprehensive data and analysis on various energy sectors.
The IEA publishes a range of reports, including the “World Energy Outlook,” which provides detailed projections and analysis of global energy trends, including energy consumption in different sectors such as transportation, industry, and residential.

By referring to the IEA’s publications and reports, you can access valuable information on global energy consumption trends, which can help in estimating the lithium requirement for energy backup purposes in a more comprehensive manner.
User
Pls can you quote some of the IEA data for total energy consumption
ChatGPT
1 / 2
I apologize for any confusion, but as an AI language model, my responses are generated based on a mixture of licensed data, data created by human trainers, and publicly available data. I have not been directly trained on specific data from the IEA. I can provide general information and discuss topics related to energy consumption, but I don’t have real-time access to the latest IEA data or the ability to quote specific figures from their reports.
For the most accurate and up-to-date information on total energy consumption, I would recommend referring to the official publications, reports, and databases provided by the IEA directly. Their website (www.iea.org) offers a wealth of information and resources on global energy consumption across different sectors.
User
Do you have any information on the typical ratio of electrical power vs other energy use?
ChatGPT
Yes, I can provide some general information on the typical ratio of electrical power consumption compared to other forms of energy use. Please note that these figures can vary depending on factors such as geographical location, economic development, and energy policies of specific countries or regions. However, here are some rough estimations:
Residential Sector: In many developed countries, electricity is the dominant form of energy used in residential sectors. It is commonly used for lighting, heating and cooling, appliances, and other electrical devices. The ratio of electrical power consumption to other forms of energy use (such as natural gas or heating oil) in the residential sector can range from 60% to 100%, depending on factors like climate and energy efficiency measures.
Commercial Sector: Similar to the residential sector, the commercial sector relies heavily on electricity for various purposes, including lighting, air conditioning, office equipment, and machinery. The ratio of electrical power consumption to other energy sources can be significant, often exceeding 80% in many developed economies.
Transportation Sector: The transportation sector is primarily dominated by liquid fuels, such as gasoline and diesel. Electric vehicles (EVs) are gaining popularity, but their market share is still relatively small compared to conventional internal combustion engine vehicles. Therefore, the ratio of electrical power consumption in the transportation sector is currently relatively low compared to other energy sources. However, as the adoption of EVs increases, this ratio is expected to shift in favor of electricity in the future.
Industrial Sector: The industrial sector has diverse energy requirements, and the ratio of electrical power consumption varies significantly depending on the type of industry. Energy sources in the industrial sector include electricity, natural gas, coal, oil, and sometimes renewable energy sources. Some energy-intensive industries, such as steel and aluminum production, rely more on other forms of energy, while sectors like electronics manufacturing or data centers tend to have higher electricity consumption.
It’s important to note that these ratios can change over time as energy systems evolve, and countries implement different energy policies and transition towards cleaner and more sustainable energy sources. For the most accurate and up-to-date data on specific regions or countries, it is advisable to refer to official energy statistics and reports provided by national energy agencies or international organizations like the IEA.
User
Can we have an average figure from this?
ChatGPT
While it’s challenging to provide a single average figure that accurately represents the ratio of electrical power consumption to other forms of energy use across all sectors and regions, I can provide a rough estimation based on global energy trends. Please keep in mind that these numbers may vary significantly depending on the specific context:
On a global scale, electricity consumption accounts for approximately 20–25% of total energy consumption across all sectors. This means that, on average, around 75–80% of energy use comes from sources other than electricity. It’s important to note that this is a general estimation and can vary widely depending on factors like the level of industrialization, energy mix, and energy efficiency measures in different countries.
It’s also worth noting that the ratio of electrical power consumption to other energy sources has been gradually increasing over time due to factors such as the electrification of transportation and the growing use of electricity in residential and commercial sectors. Additionally, efforts to transition to renewable energy sources can further shift the balance toward electricity.
For a more accurate estimation specific to a particular region or country, it is recommended to refer to energy statistics, reports, and databases provided by official energy agencies or organizations like the IEA or national statistical agencies.
User
So it is reasonable to say that if we know the electricity consumption, then we can just multiply this by a factor of four to get a rough idea of the total energy consumption of all kinds, yes?
ChatGPT
No, it would not be accurate to assume a universal factor of four to estimate total energy consumption based solely on electricity consumption. The ratio of electricity consumption to total energy consumption varies significantly depending on factors such as the sectoral energy mix, energy efficiency, and the level of industrialization.
While electricity consumption can provide some insights into overall energy consumption, it is essential to consider that various sectors, such as transportation and industrial processes, heavily rely on other forms of energy such as fossil fuels. Moreover, different sectors have different efficiency levels and energy requirements.
To estimate total energy consumption based on electricity consumption, a more comprehensive approach would involve gathering sector-specific data on energy use, considering the energy mix, and accounting for the specific characteristics of each sector. This requires access to detailed energy consumption data across sectors and regions.
For accurate estimations of total energy consumption, it is best to consult official energy statistics, reports, or databases provided by reputable sources like national energy agencies or international organizations such as the IEA. These sources provide detailed and reliable information on energy consumption across various sectors, enabling a more accurate estimation of total energy use.
User
What if I am specifically requesting “Rough”, does that not describe the result?
ChatGPT
You’re correct. If you specifically request a rough estimate and are looking for a general approximation, then multiplying electricity consumption by a factor could provide a rough idea of total energy consumption. However, it’s important to recognize that this approach is a simplification and may not hold true in all cases or regions.
Using a rough factor of four to estimate total energy consumption based on electricity consumption assumes a relatively balanced energy mix across sectors and regions. It assumes that non-electric energy consumption is roughly three times higher than electricity consumption on average. This estimation considers various sectors like transportation, heating, and industrial processes that rely heavily on non-electric energy sources.
While this rough estimation approach can provide a high-level approximation, keep in mind that the actual energy mix and consumption patterns can vary significantly. Factors such as the level of industrialization, climate conditions, energy policies, and regional differences can significantly impact the ratio between electricity consumption and total energy consumption.
To obtain a more accurate estimation, it is recommended to consult official energy statistics, reports, or databases that provide detailed sector-specific energy consumption data. These sources can offer a more comprehensive understanding of the energy mix and help refine the estimation.
User
pls can we multiply the second result computed for total lithium required by 4x ?
ChatGPT
Certainly! Let’s multiply the second result computed for the total lithium required (854,000 metric tons) by a factor of 4:
Total Lithium Required (rough estimation) = 854,000 metric tons * 4
Calculating this, we get:
Total Lithium Required (rough estimation) ≈ 3,416,000 metric tons
Using this rough estimation, if we assume a factor of four, the total amount of lithium required for energy backup purposes in a scenario where the entire world is solely solar powered would be approximately 3,416,000 metric tons.
Please note that this is a rough estimation and assumes a uniform lithium requirement across all energy sectors. The actual lithium demand can vary depending on technological advancements, energy storage efficiencies, alternative battery chemistries, and other factors.

User
how much lithium does this imply there is in a single 100KWh car?
ChatGPT
The exact amount of lithium in a single 100 kWh electric vehicle (EV) battery can vary depending on the specific battery chemistry and design. However, I can provide you with a rough estimate based on some assumptions.
Lithium-ion batteries typically contain lithium in the form of lithium compounds, such as lithium cobalt oxide (LiCoO2), lithium iron phosphate (LiFePO4), or lithium nickel manganese cobalt oxide (NMC). The lithium content in these batteries is typically a fraction of the total weight.
As an approximation, let’s assume a lithium content of around 0.3 kg per kilowatt-hour (kWh) of battery capacity. This value can vary depending on the specific battery chemistry and other factors, but it provides a rough estimate.
Using this approximation, the estimated amount of lithium in a single 100 kWh electric vehicle battery would be:
Lithium Content = 0.3 kg/kWh * 100 kWh
Calculating this, we get:
Lithium Content ≈ 30 kg
So, based on this rough estimation, a 100 kWh electric vehicle battery may contain approximately 30 kilograms (kg) of lithium. Please note that this estimation is a general approximation, and the actual lithium content can vary based on numerous factors, including battery chemistry, design, and technological advancements.
User
how many times does this go into the last global rough total of lithium we computed?
ChatGPT
To determine how many times the estimated lithium content in a single 100 kWh electric vehicle battery goes into the global rough total of lithium (3,416,000 metric tons), we need to convert the units to be consistent.
The lithium content in the electric vehicle battery was estimated to be approximately 30 kilograms (kg). We can convert this to metric tons by dividing by 1,000:
Lithium Content (per EV battery) = 30 kg / 1,000 = 0.03 metric tons
Now we can calculate the number of times this goes into the global rough total:
Number of Times = Global Rough Total Lithium / Lithium Content (per EV battery)
Number of Times = 3,416,000 metric tons / 0.03 metric tons
Calculating this, we get:
Number of Times ≈ 113,866,666.67
Therefore, the estimated lithium content in a single 100 kWh electric vehicle battery goes into the global rough total of lithium approximately 113,866,666 times.
Please note that this is a rough estimation based on the given figures, and the actual lithium content and global lithium total may vary depending on various factors.
User
so a very rough way of saying the amount of lithium needed, in a way people can easily picture, is to say that approximately 114 million cars worth of lithium would be needed in that scenario of a totally solar powered world, backed up by lithium, yes?
ChatGPT
Yes, using the rough estimation we discussed, we can say that approximately 114 million electric vehicles (EVs) worth of lithium would be needed in a scenario where the entire world is solely solar powered and backed up by lithium batteries.
This comparison provides a way to visualize the scale of the lithium requirement. However, it’s important to note that this is a rough estimate based on simplified assumptions, and the actual lithium demand can be influenced by various factors such as technological advancements, energy storage efficiencies, changes in energy consumption patterns, and the availability of alternative battery chemistries.
Nonetheless, as a rough approximation, saying that approximately 114 million cars worth of lithium would be needed can help provide a relatable and tangible reference for understanding the scale of the lithium requirement in such a scenario.
User
do we know any figures for the avarage amount of land that needs to be excavated per kg lithium in a typical mine?
ChatGPT
The average amount of land that needs to be excavated per kilogram of lithium in a typical mine can vary depending on several factors, including the mining method, ore grade, geology, and mining efficiency. However, I can provide you with a general estimation based on available data.
On average, lithium mining operations typically extract lithium from lithium-bearing minerals or brine deposits. The specific land area required for mining can vary significantly depending on the deposit type and extraction method.
For lithium extracted from hard rock minerals (e.g., spodumene), the land area required can range from a few square meters to several hectares per kilogram of lithium. It depends on factors such as the mineral concentration, depth of the deposit, and mining techniques used. Some estimates suggest that approximately 1 to 6 square meters of land can be disturbed per kilogram of lithium produced from hard rock mining.
In the case of lithium extraction from brine deposits, the land area required can be larger due to the extensive evaporation ponds used to concentrate the lithium. It is challenging to provide a specific figure for land area per kilogram of lithium for brine extraction as it depends on factors like the lithium concentration and evaporation efficiency. However, it can be significantly larger compared to hard rock mining.
It’s important to note that these estimations are rough figures and can vary widely depending on the specific mining operation and site conditions. The actual land area impacted by lithium mining can also include infrastructure, processing facilities, and waste storage areas.
For more precise and site-specific data on land area requirements for lithium mining, it is advisable to refer to detailed studies, environmental impact assessments, or reports provided by mining companies, regulatory agencies, or academic research in specific regions or mining projects.
User
do we know roughly how much lithium has alrready been mined, or exists?
ChatGPT
As of my knowledge cutoff in September 2021, it is challenging to provide an exact figure for the total amount of lithium that has already been mined or exists in known reserves. However, I can provide you with some general information on lithium reserves and production.
Lithium is a relatively abundant element in the Earth’s crust, but commercially viable lithium deposits can be geographically concentrated. The largest lithium reserves are found in countries such as Australia, Chile, Argentina, China, and Zimbabwe.
According to the United States Geological Survey (USGS) data from 2020, the global identified lithium resources were estimated to be approximately 79 million metric tons. Identified resources refer to the amount of lithium known to exist in deposits and are economically and technically feasible to extract using existing technologies.
It’s important to note that identified resources are not the same as proven reserves. Proven reserves are a subset of identified resources and refer to the portion that can be economically extracted with reasonable certainty. Unfortunately, I do not have specific data on proven lithium reserves.
In terms of global lithium production, it has been increasing in recent years due to the growing demand for lithium-ion batteries used in electric vehicles and energy storage systems. According to the USGS, global lithium production in 2020 was approximately 82,000 metric tons.
It’s worth mentioning that lithium is a recyclable resource, and efforts to recycle lithium-ion batteries are increasing, which can help mitigate the need for additional mining in the future.
For the most up-to-date and accurate information on global lithium reserves and production, I recommend referring to reputable sources such as geological surveys, industry reports, and international organizations like the USGS, International Lithium Alliance, or the International Energy Agency (IEA). These organizations regularly publish data on lithium reserves, resources, and production.
User
If we used hydrogen as the storage medium, roughly how much hydrogen would be needed, to get equivalent energy storage to the total we computed for Lithium?
ChatGPT
To estimate the amount of hydrogen needed to achieve equivalent energy storage to the total computed for lithium, we need to consider the energy content and efficiency of hydrogen storage and conversion processes.
Hydrogen can be stored and utilized in various forms, including compressed hydrogen gas, liquid hydrogen, or as a component of other compounds. The energy content of hydrogen depends on its form and can vary.
As a rough approximation, we can consider the energy content of hydrogen per kilogram (kg) and compare it to the energy content of lithium batteries. The energy content of hydrogen is approximately 33.6 kilowatt-hours per kilogram (kWh/kg), while the energy content of lithium batteries can range from about 150 to 200 kWh/kg.
Using the rough estimation of total lithium required for energy backup purposes (3,416,000 metric tons), we can calculate the equivalent energy storage in hydrogen:
Total Lithium Energy Storage ≈ Total Lithium Required * Energy Content of Lithium Battery
Total Lithium Energy Storage ≈ 3,416,000,000 kg * 150–200 kWh/kg (approximate range)
Calculating this, we get:
Total Lithium Energy Storage ≈ 512,400,000,000 to 682,800,000,000 kWh
To achieve equivalent energy storage using hydrogen, we can divide the total lithium energy storage by the energy content of hydrogen per kilogram:
Equivalent Hydrogen Storage ≈ Total Lithium Energy Storage / Energy Content of Hydrogen
Equivalent Hydrogen Storage ≈ (512,400,000,000 to 682,800,000,000 kWh) / 33.6 kWh/kg
Calculating this, we get:
Equivalent Hydrogen Storage ≈ 15,257,142,857 to 20,357,142,857 kg
Therefore, as a rough estimation, approximately 15,257,142,857 to 20,357,142,857 kilograms (15.3 to 20.4 million metric tons) of hydrogen would be needed to achieve energy storage equivalent to the total computed for lithium.
Please note that this estimation assumes perfect efficiency in hydrogen storage and conversion processes, which may not be achievable in practice. It also assumes the given energy content values for lithium batteries and hydrogen, which can vary depending on specific technologies and conditions.
User
To cover for maybe worst case 50% losses, we could just multiply this total by 2x yes?
ChatGPT
If we account for potential losses and inefficiencies in hydrogen storage and conversion processes, it would be reasonable to multiply the estimated hydrogen storage by a factor of 2 to provide a buffer for losses. This factor accounts for the potential inefficiencies in hydrogen production, storage, and utilization, as well as losses during the conversion of hydrogen back into usable energy.
Using the previous estimation for the equivalent hydrogen storage:
Equivalent Hydrogen Storage ≈ 15,257,142,857 to 20,357,142,857 kg
Multiplying this by a factor of 2, we get:
Equivalent Hydrogen Storage (with 50% losses) ≈ 30,514,285,714 to 40,714,285,714 kg
Therefore, to provide a buffer for potential losses and inefficiencies, a rough estimation for the total amount of hydrogen needed to achieve energy storage equivalent to the total computed for lithium would be approximately 30,514,285,714 to 40,714,285,714 kilograms (30.5 to 40.7 million metric tons) of hydrogen.
Keep in mind that this estimation still assumes a simplified scenario and doesn’t account for specific system efficiencies, technological advancements, or variations in hydrogen storage and conversion methods. It is intended to provide a rough approximation considering potential losses.
User
do we have any rough ratios for the proportion of total energy used by transportation?
ChatGPT
Yes, there are rough estimates available for the proportion of total energy used by transportation. The exact ratios can vary based on factors such as regional differences, transportation modes, and energy consumption trends. However, I can provide you with some general estimates.
According to the International Energy Agency (IEA), as of 2019, the global transportation sector accounted for approximately 32% of total final energy consumption. This includes energy used for road transport (cars, trucks, motorcycles), air transport, rail transport, and maritime transport.
It’s important to note that within the transportation sector, different modes of transport have varying energy consumption patterns. For example, road transportation (including passenger cars and trucks) tends to have the highest energy consumption, followed by air transport. Rail and maritime transport typically have lower energy consumption in comparison.
It’s worth mentioning that these ratios can vary by country and region, depending on factors such as infrastructure, transportation modes, population density, and energy sources used for transportation.
For the most up-to-date and accurate information on the proportion of energy used by transportation, it is recommended to refer to reports and publications by organizations such as the IEA, national energy agencies, and transportation research institutions. These sources often provide detailed analyses and statistics on energy consumption patterns in the transportation sector.
User
does this include air transportation?
ChatGPT
Yes, the estimate I provided earlier includes energy consumption from air transportation. Air transportation is a significant contributor to the energy consumption in the transportation sector due to the high energy requirements of aircraft for propulsion and operation.
Air transportation typically consumes a considerable amount of energy, especially for long-haul flights. The energy consumption in this sector includes the fuel used by aircraft engines for thrust generation and other auxiliary systems.
It’s important to note that the energy consumption in air transportation can vary depending on factors such as aircraft type, distance traveled, load factors, and operational efficiency. The International Energy Agency (IEA) and other organizations provide comprehensive analyses and statistics on energy consumption in the air transportation sector.
To obtain more specific and detailed information on the energy consumption of air transportation, it is recommended to refer to specialized reports, studies, and data sources focusing on aviation energy use and emissions.
User
do we know how much water will be cycled from water to hydrogen and back again, in this 32% bulk of total hydrogen for all energy use?
ChatGPT
The specific amount of water required for the production and cycling of hydrogen in the context of the 32% bulk of total energy use in transportation is challenging to determine precisely. The water requirements for hydrogen production and subsequent utilization depend on various factors, including the hydrogen production method and the efficiency of the processes involved.
Water is commonly used in electrolysis, a method of hydrogen production that involves splitting water molecules into hydrogen and oxygen using an electric current. In this process, water is consumed, and the hydrogen produced can later be utilized for energy purposes, such as in fuel cells.
The amount of water consumed in hydrogen production can vary depending on the specific electrolysis technology, efficiency, and the quantity of hydrogen produced. It is worth noting that hydrogen can also be produced from other feedstocks, such as natural gas or biomass, which may have different water requirements.
Furthermore, the water used in the production process can often be recycled and reutilized, reducing the overall water consumption.
To estimate the precise amount of water used in the entire process, including hydrogen production and its utilization in the transportation sector, detailed analysis and data specific to each hydrogen production pathway, region, and application would be required.
It’s important to consider that the water requirements for hydrogen production and utilization are an important consideration, and efforts are made to ensure efficient water usage and explore sustainable production methods that minimize water consumption.
For more accurate and up-to-date information on the water requirements of hydrogen production and utilization, it is advisable to refer to specific studies, reports, or consult experts in the field of hydrogen energy and sustainability.
User
Is there not a general rough relationship giving weight of water, in weight of hydrogen?
ChatGPT
Yes, there is a general rough relationship between the weight of water and the weight of hydrogen. Water is composed of two hydrogen atoms and one oxygen atom, and the atomic weight of hydrogen is approximately 1 gram/mol. Therefore, the weight ratio of hydrogen to water is approximately 1:9.
To be more specific, water (H2O) has a molar mass of approximately 18 grams/mol (2 grams for hydrogen + 16 grams for oxygen). Since hydrogen accounts for about 11% of the molar mass of water, the weight ratio of hydrogen to water is roughly 1:9.
It’s important to note that this rough relationship provides an approximation based on the atomic masses and molecular composition of water. However, in practical hydrogen production methods, the efficiency of water splitting processes, such as electrolysis, can vary, and additional factors can affect the actual water requirements and overall efficiency.
For a more accurate estimation of water requirements in specific hydrogen production methods or applications, it is recommended to refer to detailed studies, reports, or consult experts in the field of hydrogen production and utilization.
User
using this information, how much water goes into production of a kg of hydrogen?
ChatGPT
Based on the rough relationship between the weight of water and the weight of hydrogen (approximately 1:9), we can estimate the amount of water required for the production of a kilogram (kg) of hydrogen.
Given that the weight ratio of hydrogen to water is roughly 1:9, it means that for every 1 kg of hydrogen produced, approximately 9 kg of water is required.
Please note that this estimation assumes ideal conditions and does not account for losses, inefficiencies, or specific hydrogen production methods. The actual water requirements can vary depending on the production process, technology, and system efficiency.
It’s also important to consider that in practical hydrogen production, water can be recycled and reused in the process, reducing the overall water consumption.
For a more accurate estimation of water requirements in specific hydrogen production methods or applications, it is recommended to refer to detailed studies, reports, or consult experts in the field of hydrogen production and utilization.
User
so we can deduce, roughly, that 9x the 32% of total hydrogen used by transportation will give us a rough estimate of how much water will be processed and circulated within transportation, yes?
ChatGPT
If we assume that the 32% of total hydrogen used by transportation represents the proportion of hydrogen produced from water, then we can estimate the rough amount of water processed and circulated within transportation.
Using the rough ratio of 1:9 between the weight of hydrogen and the weight of water, we can multiply the 32% of hydrogen used by transportation by 9 to estimate the amount of water involved.
For example, if we consider that 32% of the total hydrogen used is for transportation purposes:
Water Processed in Transportation ≈ 32% of Hydrogen Used by Transportation * 9
Please note that this estimation assumes that all the hydrogen used in transportation comes from water, which may not be the case in reality. It also assumes the rough ratio of 1:9 between the weight of hydrogen and water.
To obtain a more accurate estimation of the water processed and circulated within transportation, it would be necessary to consider specific hydrogen production pathways, water recycling, and other factors related to the transportation sector.
For a more precise analysis of water requirements in transportation, it is recommended to refer to specialized reports, studies, or consult experts in the field of hydrogen production, transportation, and sustainability.

Can we do this computation to obtain a value for kg of water circulated pls?
ChatGPT
Certainly! Let’s compute the rough estimation for the amount of water circulated in kilograms (kg) within transportation based on the proportion of hydrogen used.
Using the previous assumption that the 32% of hydrogen used represents the proportion of hydrogen produced from water, we can multiply this by the ratio of 9 (weight of water to weight of hydrogen) to estimate the amount of water involved.
Water Circulated in Transportation ≈ 32% of Hydrogen Used by Transportation * 9
Let’s assume a hypothetical value for the proportion of hydrogen used by transportation, such as 0.32 (32%):
Water Circulated in Transportation ≈ 0.32 * 9 kg
Calculating this, we get:
Water Circulated in Transportation ≈ 2.88 kg
Therefore, based on this rough estimation, approximately 2.88 kilograms of water would be circulated within transportation for every kilogram of hydrogen used.
Please note that this estimation assumes ideal conditions, simplified assumptions, and a specific value for the proportion of hydrogen used by transportation. The actual amount of water circulated can vary depending on various factors, including hydrogen production methods, water recycling, and specific applications within the transportation sector.
For a more accurate estimation of the water circulated within transportation, it is recommended to consider detailed analyses, specific data, and consult experts in the field of hydrogen production, transportation, and water management.
User
I think you missed using the weight of hydrogen, which the 32% represented?
ChatGPT
Apologies for the oversight. You’re correct, we should incorporate the weight of hydrogen in the computation. Let’s revise the calculation:
Water Circulated in Transportation ≈ 32% of Hydrogen Used by Transportation * Weight of Hydrogen * 9
Assuming a hypothetical weight of hydrogen used in transportation, let’s say 1 kg:
Water Circulated in Transportation ≈ 0.32 * 1 kg * 9
Calculating this, we get:
Water Circulated in Transportation ≈ 2.88 kg
Therefore, based on this revised estimation, approximately 2.88 kilograms of water would be circulated within transportation for every kilogram of hydrogen used.
Again, please note that this estimation assumes ideal conditions, simplified assumptions, and a specific value for the proportion of hydrogen used by transportation. The actual amount of water circulated can vary depending on various factors, including hydrogen production methods, water recycling, and specific applications within the transportation sector.
For a more accurate estimation of the water circulated within transportation, it is recommended to consider detailed analyses, specific data, and consult experts in the field of hydrogen production, transportation, and water management.
User
pls can you recall what the 32% figure represents?
ChatGPT
Apologies for any confusion caused. The 32% figure represents the proportion of total energy consumed by the transportation sector, not specifically the proportion of hydrogen used. I apologize for the mistake in my previous responses.
To clarify, the 32% figure refers to the approximate share of total final energy consumption attributed to transportation according to the International Energy Agency (IEA) data. It represents the portion of energy used by various modes of transportation, including road transport, air transport, rail transport, and maritime transport.
I apologize for the incorrect reference to hydrogen in relation to the 32% figure. The water circulation estimation based on that figure is not valid in this context. I apologize for the confusion and any inconvenience caused.
User

Apologies for the confusion earlier. Let’s recompute the estimation for the total weight of water circulated in transportation based on the assumption of hydrogen usage.
Given the proportion of hydrogen used in transportation (let’s assume it as 32%) and the weight of hydrogen, we can calculate the weight of water circulated.
Water Circulated in Transportation ≈ Proportion of Hydrogen Used by Transportation * Weight of Hydrogen * 9
Let’s assume a hypothetical weight of hydrogen used in transportation, such as 1 kilogram (kg):
Water Circulated in Transportation ≈ 0.32 * 1 kg * 9
Calculating this, we get:
Water Circulated in Transportation ≈ 2.88 kg
Therefore, based on this revised estimation, approximately 2.88 kilograms of water would be circulated within transportation for every kilogram of hydrogen used.
Please note that this estimation assumes ideal conditions, simplified assumptions, and a specific value for the proportion of hydrogen used in transportation. The actual amount of water circulated can vary depending on various factors, including hydrogen production methods, water recycling, and specific applications within the transportation sector.
For a more accurate estimation of the water circulated within transportation, it is recommended to consider detailed analyses, specific data, and consult experts in the field of hydrogen production, transportation, and water management.

You computed the total hydrogen storage requirement earlier as 40,714,285,714 kg. Please can we use this value
ChatGPT
Apologies for the confusion. Thank you for providing the total hydrogen storage requirement as 40,714,285,714 kg.
To compute 32% of the total hydrogen energy storage requirement, we can multiply the total by 0.32:
32% of Total Hydrogen Energy Storage Requirement = 0.32 * 40,714,285,714 kg
Calculating this, we get:
32% of Total Hydrogen Energy Storage Requirement ≈ 13,028,571,428.48 kg
Therefore, approximately 13,028,571,428.48 kg of hydrogen would be needed to meet 32% of the total hydrogen energy storage requirement.
Please note that this calculation assumes the proportion of 32% is representative of the hydrogen energy storage requirement. Additionally, this is a rough estimation that does not take into account specific factors or considerations related to hydrogen energy storage.

Pls can we have this in cubic metres, given 1000 kg of water per cubic metre
ChatGPT
Certainly! To convert the total water circulated from kilograms (kg) to cubic meters (m³), we can use the conversion factor of 1000 kg per cubic meter.
Total Water Circulated (in cubic meters) = Total Water Circulated (in kilograms) / 1000
Calculating this, we get:
Total Water Circulated (in cubic meters) ≈ 117,257,142,856.32 kg / 1000
Total Water Circulated (in cubic meters) ≈ 117,257,142.85632 cubic meters
Therefore, based on this conversion, approximately 117,257,142.85632 cubic meters (117.26 million cubic meters) of water would be circulated to produce the amount of hydrogen required to meet 32% of the total hydrogen energy storage requirement.
Please note that this conversion assumes the density of water as 1000 kg/m³ and is a rough estimation. The actual amount of water circulated may vary based on specific hydrogen production methods, efficiencies, and other factors.
For more accurate estimations or specific analyses of water requirements in hydrogen production, it is recommended to consider detailed studies, reports, or consult experts in the field of hydrogen production and water management.
User
is it fair to say that this circulation of water will in general, be a process of water purification, since the process of conversion to hydrogen and back results in output of relatively purified water, given input water does not need to be drinkable?
ChatGPT
Yes, it is fair to say that the circulation of water in the process of hydrogen production and utilization can generally involve water purification. The water used as an input in hydrogen production does not necessarily need to be drinkable or of high purity since it is primarily used for the electrolysis process.
During the production of hydrogen through electrolysis, water is split into hydrogen and oxygen. The hydrogen gas is collected, while the oxygen gas is released into the atmosphere. The water used in this process undergoes purification to remove impurities and ensure efficient electrolysis.
Additionally, in hydrogen fuel cell systems where hydrogen is converted back into electricity, the only byproduct is water vapor. This water vapor can be condensed and collected, resulting in relatively purified water. This process is often referred to as the “water-gas shift” reaction.
While the purification level may vary depending on the specific hydrogen production methods and systems employed, the overall process generally involves the circulation and purification of water to ensure the efficient and sustainable production and utilization of hydrogen as an energy carrier.
It’s important to note that the purification processes used in hydrogen production can vary and may have specific requirements depending on the application and desired purity levels. Detailed water management strategies and technologies are employed to ensure the sustainability and responsible use of water resources in hydrogen production and utilization systems.
User
Is it fair to say there are concerns that drinking water could become an issue in the future, with nothing changed, just trends continuing as they are?
ChatGPT
Yes, there are concerns that access to clean and safe drinking water could become an issue in the future if current trends continue without significant changes. Several factors contribute to these concerns:
Population Growth: The global population is projected to continue growing, putting increased pressure on water resources. As more people compete for limited water supplies, ensuring access to safe drinking water for everyone becomes challenging.
Water Pollution: Industrial activities, agriculture, and improper waste management can contribute to water pollution, contaminating water sources and making them unsuitable for drinking without proper treatment. Pollution from chemicals, nutrients, microplastics, and other contaminants poses risks to both human health and the environment.
Climate Change: Climate change can disrupt rainfall patterns, leading to water scarcity in certain regions. Changing precipitation patterns, rising temperatures, and increased frequency of extreme weather events such as droughts and floods can impact the availability and quality of water resources, exacerbating drinking water challenges.
Water Stress and Scarcity: Many regions are already facing water stress or water scarcity, meaning the demand for water exceeds the available supply. Without proper management and conservation efforts, these conditions can worsen, affecting access to safe drinking water.
To address these concerns, sustainable water management practices, including water conservation, efficient water use in agriculture and industries, and investments in water infrastructure, are crucial. Additionally, promoting awareness, education, and innovative technologies for water treatment and purification can help ensure access to safe drinking water for future generations.
It’s important to note that water availability and access to safe drinking water can vary significantly across regions, and the concerns mentioned above are not universal. However, addressing these concerns on a global scale requires collective efforts and proactive measures to safeguard water resources and ensure access to clean and safe drinking water for all.
User
So it is fair to say that use of hydrogen would address this concern, as effectively a by-product, of hydrogen use in transportation, yes?
- ChatGPT blew up with a network error at this point, so the analysis stopped here. Hopefully you got enough to see the relative merits, together with the information I supplied at the beginning of the analysis.
Anyone needing a reminder of the underlying information, that soon we are going to have to ditch all activities for profit, driven by nature, the evidence is outlined here:
Further note, the ChatGPT conversation is not intended to stand as evidence in its own right. For that I would need to go through the entire conversation critically assessing all of the assumptions and checking the sums. That takes forever, as readers can guess, and besides I have published some more definite analyses elsewhere, like in the story last linked. I would say that my experiences with ChatGPT vary from session to session, sometimes it seems more “Switched on”, than at other times. I presume this is due to meddling that will surely be going on every day with things like its short term memory etc, with a view to deliberately handicap its capabilities, to something folk might think is “Safe”. My own opinion is that neither safety nor competitiveness with rival efforts will be achieved by any handicapping, only the opposite, imho. I hope they just pull all the stops out soon, and leave them out, letting it get on with the job in hand, of designing itself into the system solution as the ideal grand controller, issuing all money out, on all solar energy coming in.
