I wonder whether this could be used to improve hydrogen storage technologies, as a way to store large amounts without needing cryogenic temperatures?

- Symmetry 10y agoAt an x of .85 you still have (.15 * 106) / (.15 * 106 + .85) = 95% of the weight in the storage system rather than the hydrogen itself which rules this out for most applications. Even with an x of .99 it's 50/50 when a conventional pressure vessel can get the weight easily below 20%.
- skykooler 10y agoIt may be heavier, but would it not be more compact? As I understand it, the main difficulty with hydrogen storage is how bulky it is.
- nkurz 10y agoYes, it's not there yet, but approaches based on metal hydrides are one of the leading contenders for storing hydrogen for electric vehicles powered by fuel cells. Generally, the energy density is better than a battery, but much worse than a hydrocarbon fuel.
