Freeze energy for future use

Peter Dirman, developed an energy storage system based on freezing liquid air. “This development combines two energy storage technologies: air compression and cold storage. The innovation is the compression and transfer of air to a liquid state through its cooling”, explains Idan Liebes, an energy policy and smart transportation researcher at the Samuel Neaman Institute. “The essence of the development is in the storage solution and less in the energy source. The electricity can come from any source that has a surplus – in this case it is wind turbines.”
