> I haven't seen anyone seriously propose hydrogen based powerplants. Well, Japan has. You may have read about it recently in the article linked at the top of this comment page. Here's another source from Japan itself: https://www.meti.go.jp/english/policy/energy_environment/global_warming/ggs2050/pdf/02_hydrogen.pdf https://www.meti.go.jp/english/policy/energy_environment/glo... > Accelerating the commercialization of hydrogen power generation turbines in Japan by supporting the early demonstration with actual equipment, with a view to capturing the global market in the future > Assuming that the price of the 100% hydrogen-derived electricity retail menu and the price of the 100% natural gas-derived electricity retail menu are the same, and assuming that only the latter retail menu has a price hike of about 1.8 yen/kWh (based on the time when the cost of LNG-fired power generation was at its highest), a standard household would be able to save about 8,600 yen/year.
