It’s not that secret. fossil fuel companies are pushing “blue hydrogen” (ie regular fossil fuel produced hydrogen plus carbon capture) pretty aggressively. Of course, you can just not do the carbon capture step to save cost, and boom, you’re still using fossil fuels with climate impact just as bad as before. Anyway, green hydrogen is good, and while it won’t ever be as cheap for vehicles as electrification (and the vehicle costs are higher for fuel cell vehicles, too), it is important for industrial uses of hydrogen, like iron ore reduction to metal and ammonia fertilizer. There was a time in the 2000s when natural gas based hydrogen was about $2.50/kg. I think we can get green hydrogen down to that level at large scale. Biggest question is really the electrolyzer capital cost as renewable electricity is already cheap enough.
