I found the napkin math for getting green hydrogen to 1 USD per kg pretty interesting. https://news.ycombinator.com/item?id=37155241 https://news.ycombinator.com/item?id=37155241 The primary assumption is that solar energy is going to be almost free within a decade because we will massively overprovision it to balance yearly variation. Then you need to find a cheap industrial process which uses electricty to do something which has a positive climate impact.
