You don't need hydrogen, you need electrons. I prefer to store my electrons directly in atomic element 3, so I can fill it directly with electrons and get them back out, at much higher efficiencies than this process.
- sfifs 6y agoIn all energy storage tech, you're trading off energy density (eg. energy per kilogram) against power rating (energy per second that you can transfer). Then you have trade-off considerations like safety, emissions (which have a value - see Tesla P/L), production cost, supply chain etc. For different use cases, different trade-offs may work out. Lithium battery tech typically trades off power rating and energydensity (Earlier - how much acceleration and range, nowadays with better batteries - how fast you can fill up) for other benefits. This tech prioritises safety and power rating at some production cost and supply chain. Gasoline gives emissions and engine complexity vs other conveniences Rockets prioritize both power and energy density over everything else and uses LH2 and LOX dealing with cryo complexity

Keep in mind that both rockets and ion engines actually have fairly low realized energy density, because they can't just rely on atmospheric oxygen.
