…and with what devices? Currently, there’s 11 GW of Electrolysis capacity available worldwide, with about 400 GW potentially realised by 2030. That’s 0.07% now of the total production of 16 TW from fossils, increasing to a whopping 2.5% in 2030. And that does not take into account that energy markets will be competing with industry that uses hydrogen as a reduction agent (steel, for example) to replace fossils. It also does not take into account that hydrogen is not as easy to transport than other fossils.
Hydrogen might be the solution to the energy crisis, but for that we’d have to pick up our game immensely. Which will not happen if everyone thinks hydrogen is already freely and abundantly available.
