Still sounds more expensive than a holding pond.
- pfdietz 2y agoIf one compares the heat of combustion of hydrogen stored at 100 bar and 20 C, to the energy of water elevated by 100 meters, the former exceeds the latter (per unit volume) by a factor of 1000. So that "holding pond" is going to be much, MUCH larger than the solution-mined cavern for storage systems of equal capacity (and remember one needs two reservoirs.)
