If weight/volume is not an issue, there are lots and lots of technologies that will work well for energy storage. Compressed air, flywheels, heated water, lead-acid.
- tomp 7y agoAre those (e.g. flywheels, compressed air) production-ready or just start-up ideas? Also flywheels have a pretty destructive worst-case failure mode... > heated water How does that work (specifically for storing electricity)?
- fulafel 7y agoRe energy storage generally, heating is a top energy user in many parts of the world and I think relevant to the conversation. In places with CHP plants and district heating systems, the thermal battery concept is tried and tested. Since the system is already based on circulating hot water around, putting some storage tanks/caverns in the system is straightforward.
- inscionent 7y agoNot if the flywheel is in space!
- leetbulb 7y agoMany data centers use flywheels
- Iv 7y ago> flywheels have a pretty destructive worst-case failure mode... Do they? If their casing is solid enough, the worst that they can do is damage themselves internally and heat up a bit. There is no buildup of pressure, leakage of chemicals or risk of a chemical fire.
- Iv 7y agoIndeed. For this kind of discussion, it is good to have this table in head: https://en.wikipedia.org/wiki/Energy_density#Table_of_energy_content https://en.wikipedia.org/wiki/Energy_density#Table_of_energy...
- jaakl 7y agoIn utility scale the only usable thing now is hydro pump station like https://en.wikipedia.org/wiki/Kruonis_Pumped_Storage_Plant https://en.wikipedia.org/wiki/Kruonis_Pumped_Storage_Plant. Requires luck with geography: natural elevation and water not too far away.
