Long Term Storage of Heat in Isomers
Chalmers University in Sweden has come up with a novel way of long-term (years) storing (solar) heat, namely in isomers.
– Discharge operating temperature: 63 C
– Storage capacity: 0.25 kWh/kg (2x Tesla Powerwall)
– 125 charge-discharge cycles without detoriation.
Researcher Moth-Poulsen thinks there is a lot of potential for improvement, like operating temperatures of 110 C.
