Charlie Stross@alexproe @ChrisMayLA6 Hydrogen is greenwashing—it's almost 100% produced by reforming methane (natural gas): electrolysis from water is ferociously expensive. It's also much lower energy density per unit volume than methane, diffuses through metal, as a cryogenic liquid it's murderously hard to handle and embrittles seals and metal, and it's explosive when mixed with air in almost any ratio. Locos powered by hydrogen are leaking fuel-air explosive bombs, and you want them in passenger stations?
