Hydrogen storage exists on PowerPoint slides that usually slightly understate the overhead required to build new, or adapt current gas infrastructure. Spoiler: those problems are not trivial to overcome. That's why they're mostly PowerPoint projects.
Hydro storage works, and along with hydro power, it is usually well exploited in countries that can benefit from it (e.g. alpine). Problem is you tend to run out of valleys and villages to flood after a certain point.
Why chase paper or limited impact solutions when massively available and clean ones already exist?
- pfdietz 4y agoAt least you seem to be admitting these are actual technologies. We are now just haggling over the cost. The estimates for the costs of storage needed to turn renewables into baseload aren't enormous. This is why Exelon abandoned the idea of building more nuclear power plants, and instead focused on storage. BTW, the available locations for off-river pumped hydro are enormous. On a global scale it vastly exceeds what would be necessary for a 100% renewable world. There are areas without the vertical relief needed, but other storage technologies could work there. The salient thing you see when looking at storage is that there are so many different ways to do it. Nuclear stans are loudly asserting that none of them can work. This is a very strong assertion and deserves much more detailed argument than the usual bare assertion.
