I am happy to be corrected, but I believe the only industrial scale production of hydrogen is splitting hydrocarbons. Using electrolysis is hugely inefficient.
If this is true, a lot of talk of hydrogen is submarine marketing for the fossil fuel industry.
- ip26 6y agoHydrogen fuel cell vehicles are supposedly meant to be powered by electrolysis, which in turn would be driven by renewables. Personally, I suspect the fossil fuel industry loves hydrogen fuel cells mainly because they are safely 10-20 years away.
- zizee 6y ago> Hydrogen fuel cell vehicles are supposedly meant to be powered by electrolysis Yes, that's what people imagine is happening when talking hydrogen powdered cars. But I believe that electrolysis is so inefficient that it's not a realistic option for producing hydrogen on an industrial scale. This leaves us with breaking down hydrocarbons, hardly a "green" option.
- Guvante 6y agoA quick Google shows a chart saying $42/MWh which is on scale with electricity production in general. Sounds too high for something like energy storage but I assume that is in the ballpark for reasonable car pricing from the phrasing of the report. Also honestly we could use "good enough" ways of reducing emissions. Waiting for perfect would be a bad idea.
