Unfortunately, there's no efficient process for that. Efficiency of electrolysis (when not using expensive catalysts) is around 50%.

- ars 12y agoUse thermolysis instead. You can power it with waste heat from a nuclear plant.
- gambiting 12y agoAnd that's not even half of the process. Electrolysis produces gaseous hydrogen, it needs to be cooled down to store as a liquid, which requires a LOT of energy as well.
- sliverstorm 12y agoWe know that hydrogen has obstacles when it comes to efficiency... but we also know that batteries have obstacles when it comes to chemical environmental friendliness (primarily manufacture and disposal). Has anyone done a comparison of that aspect of environmental impact?
- Symmetry 12y agoI seem to recall that synthesizing methane or hydrocarbons from water and atmospheric CO2 isn't that much less efficient than that. Given the efficiency of internal combustion engines versus fuel cells and existing infrastructure you might as well get your carbon neutral transportation that way instead of with hydrogen.
