>Hydrogen can be stored underground in the form of salt caverns or domes.
And is it? On a grid-scale? And if not, why not? Is it because there are major technical hurdles that need to be overcome, and it's a completely unproven approach?
This is what happens with these renewable discussions. Proponents will just throw out theories as facts and non-existent technologies as ready for prime time and gloss over intrinsic technical hurdles ... meanwhile in the real world, even though there is desperation to move from fossil fuels, somehow those ideas aren't implemented. Why is Germany building NEW natural gas pipelines, instead of building hydrogen storage? The Syrian conflict is partially exacerbated by geopolitical jockeying between Russia and Turkey and others for the right to build future pipelines into Europe. What do they all know that we don't know?
- pfdietz 6y agoIt's not happening yet because the cost of CO2 is not high enough yet to make it competitive. Having said that, Germany is putting a lot of money into hydrogen, and this is driving down the cost of electrolysers, the same way Germany drove down the cost of PV a decade ago.
