German researchers have designed an innovative measurement method that tracks battery health live during operation.

PCM-based thermal battery to store solar power via heat pump Norway’s SINTEF has designed a heat storage system based on phase change materials (PCM) that can support PV generation and peak shaving.

The battery can reportedly store energy between -30 C and 120 C for a long period with only 1-2% of energy loss per day. Heatventors is offering the system with capacities of 10 kWh, 30 kWh, and ...
