Pumped Heat Electricity Storage (PHES) is a new technology developed by Isentropic, which promises to be the cheapest and most convenient way to store and recover electricity.
The shift to renewable and nuclear energy is challenging the power supply industry worldwide due to the intermittency of renewable sources and the inflexibility of nuclear energy. A solution is needed to store and recover electrical energy to prevent disruptions to the electricity supply.
The critical issue is the cost of energy storage. Storing hot and cold is the cheapest way to store energy and is well understood. Our system transforms electrical energy into a temperature difference between two volumes of crushed mineral material. The system then efficiently recovers electricity from that temperature difference.
