CO2 battery could make wind and solar dispatchable at a lower price
Interesting: CO2 gets pressurized, cooled to liquid temperatures via refrigeration, then uncompressed to spin a turbine when energy is needed.<p>Concerning:<p>> The engineer explains that Energy Dome does not want to build projects itself.<p>> “We don’t have the capability to grow as fast as the market requires,” he says. “So our model is to license the technology to EPC companies or IPPs, utilities, the final user, because that is the best way for us to expand geographically and by sector.<p>They are so confident in the economics of this tech that they'd rather someone else invest in it. How generous and not at all suspicious.
