Yeah in addition to flow batteries there are also grid scale thermal batteries, though these are targeted more towards long duration energy storage: run electricity through a large carbon block in a shipping container form factor to heat it up, then use infrared photovoltaics to convert back to electricity when desired.
- Teever 2y agoI'd be interested in learning more about this carbon block battery that you're describing. I'm also curious how it compares in cost effectiveness to this battery that's based on sand. https://tambaynews.blogspot.com/2022/07/worlds-first-commercial-sand-battery.html https://tambaynews.blogspot.com/2022/07/worlds-first-commerc...
- szvsw 2y agoAntora is one example: https://antoraenergy.com/ https://antoraenergy.com/ In addition to a few hundred mil in funding, they have support from NREL/DoE, eg https://www.nrel.gov/news/features/2024/how-nrel-helps-startups-from-the-beginning.html https://www.nrel.gov/news/features/2024/how-nrel-helps-start... I also was at a conference recently that had some cool feasibility studies done by people at NREL about using TPV for LDTES with Antora product specs used for boundary conditions, but I don’t think that’s published yet. I’ve also seen FourthPower mentioned a few times but I don’t know much about them or how feasible their tech actually is. https://gofourth.com/our-technology/ https://gofourth.com/our-technology/ Energy storage is not my area of expertise (but very much adjacent to it).
