- isthisthingon99 4y agoTo start a ICE car you need ignition. Maybe something similar, so long as the conversion process could be split between powering the car for use and continued fuel conversion.
- gus_massa 4y agoThe problem is that you only have a fixed amount of energy. If yuo use some energy to split water, then when you burn the hydrogen you get the same ammout of energy back. Moreover, some part will be lost in the conversion.
- jeeeb 4y agoWhy would you need to do that? You produce hydrogen via “direct-air electrolysis” and then use it as a fuel by reacting it with oxygen in a fuel cell. Compared to lithium ion batteries it’s just a different chemical medium for storing energy. In practice you’d probably have something like a fuel station producing hydrogen in-situ with energy pulled from the grid.
