Store it in solid-state form via Aluminum Hydride (Alane). Better stability & even less weight. Some fundamental scaling issues yet to be solved, but very much within reach.
- perlgeek 6y agoThis would be a lot more reassuring if the same (better storage in a bound form) hadn't been promised for at least 20 years, back then being solved in principle, but not being ready for prime time...
- beambot 6y agoYou would've said the very same about solar, wind, & grid-scale battery storage even 5-10 years ago. The commitment to scale is what made the "old" technology economically feasible. Incremental advances also played a role. This same equation is playing out for nuclear, Alane, and others. It's a matter of commitment & will -- both of which are gaining momentum.
- cwkoss 6y agoHow is it less weight? I'm assume this is counting the weight of the pressure vessel, and aluminum hydride reduces the pressure needed to contain the hydrogen?
- beambot 6y agoAluminum Hydride doesn't require a pressure vessel at all -- hydrogen is released at low pressure through heating -- which dramatically reduces the weight of the system.
