I don't understand why the term "renewables' is still used when talking about things like this.
It seems like there is still a very big profit motive, which is obfuscated by things like the "carbon market", which is all about making money from appearing to be fixing the problem, rather than just fixing the problem.
As long as business is funded by money-as-debt, it is committed to repaying by extraction. If the money was donated to businesses with no obligation to repay, then the company doing the development would be free to use its infrastructure to capture and sustain itself from money-as-sunlight, thus removing itself from the extraction load
It is pretty simple; free green hydrogen, and pow money can come only from solar energy. Winding C02 into the mix is creating a market for C02, which does not help at all.
There are only two sources of energy; the stored energy of Earth, or the continuous energy of the sun. None of it is renewable.
The usable energy from the stored resources of Earth are about done, so now we need to turn to the energy of the sun.
The energy of Earth always requires ongoing work to extract, so it always has to be paid for, it can never be free.
The energy of the sun requires no work beyond that to implement the initial seed infrastructure required to begin collecting it and monetising it, after that, all money, and all fuel are comletely free, infinitely scaleable, and endless.
Mixing C02 in with that seems like a cynical attempt to cover up the reality; money has to go free, when the energy goes free, and it will, when we turn to the only real source of energy, the sun.
