Energy losses from this scenario are high enough that there are probably other usage scenarios that would beat it. It's certainly the case that there are already many peak-storage solutions deployed and none of them involve hydrogen.
- nkurz 9y agothere are already many peak-storage solutions deployed and none of them involve hydrogen That seems like an overstatement. There has definitely been considerable research into using hydrogen as "peak-storage solution", and I think some approaches are actually being deployed. For example, here's an NREL story from last year: https://www.nrel.gov/continuum/energy_integration/hydrogen.html https://www.nrel.gov/continuum/energy_integration/hydrogen.h... The article agrees with you that the current inefficiencies of the round-trip to the grid are large, but claims that generating hydrogen as a vehicular fuel using excess solar and wind power does make sense. So if the parent was envisioning those "giant fuel cells" as being mobile (or located somewhere really remote), then he's not that far off.
- dpark 9y agoThat’s a demonstration project and to the extent that it’s “deployed”, so are tokamaks. Hydrogen may be feasible for peak balancing but it seems correct to say that it is not currently used this way.
- greglindahl 9y agoOK, so what % of peak storage solution is hydrogen?
