I've been researching this for a number of years as also a long practicing Systems Engineer and agree completely hydrogen is the future.
On the way to use it most effectively, domestic and community solar is already far more developed than grid and utilities companies give it credit for. All data comes from them. But we can see the evidence of DCS by looking at population numbers coupled with utilities data, and we can see they are diverging, showing that utilities and grid have already lost an awful lot of business to DCS. In UK for 2022 alone, that loss was around 50Bn. for 2023 it is likely to be more than 150Bn. Since 2005 it stands at 457Bn.
There maybe we see the real reason utilities energy companies are going belly up despite government support, whilst selling energy at the highest prices ever, and still we are at risk of power cuts. The utility energy supply business has never been more tenuous, it is poised to collapse.
This is why I advise any and all communities including businesses, governments, manufacturing companies and even Internet server companies, to put in their own solar infrastructure, backed by hydrogen electrolysis, tanks, and fuel cells, before they get caught out.
This is the only way to get energy independence, bringing with it also drinking water circulation (from the exhaust outputs of hydrogen consuming vehicles and backup facilities), and hydrogen fuel outlets for transportation on every street corner, since by nature, any facility successfully backing up by hydrogen 24/7 has to generate an excess, it is impossible to predict before any particular period how much hydrogen is needed for any backup application, therefore there will always be excess.
This is a technological revolution waiting to happen. All it is waiting for, is for the utilities supply industry to give in and admit defeat.
When that happens, massive UBI has to be issued, which will fund all remaining scaling up and hydrogenisation, within only a year or two.
Then we will likely see a very busy industry of processing secondhand BEVs and even ICE's to HEV, And HICE respectively, whilst pretty much all new vehicles will be HEV.
Aero Engines for HICE are also already developed and tested by companies like Airbus, and Rolls Royce, (My usual domain as a systems Engineer)
