Antora 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).
