Tesla co-founder and CTO JB Straubel has invested in energy storage startup Axiom Energy. The company's Refrigeration Battery uses excess cooling capacity to "store cooling" by freezing salt water. This allows businesses like grocery stores to shift from electricity to this stored cooling during peak energy demand. "Energy storage is a key technology that is enabling the ongoing deployment of renewables on the grid," says Straubel. "Axiom Exergy has developed a compelling solution that provides unique distributed energy benefits and delivers immediate value to supermarkets and cold storage facilities."

The US Department of Energy (DOE) has announced that it will invest $7 million to accelerate the development of clean, efficient engines through the co-optimization of engine and fuel technologies. In a partnership with the DOE's Bioenergy Technologies Office and Vehicle Technologies Office, it is seeking proposals for projects that use such optimization for affordable, scalable, sustainable fuels for low-emissions engines through spark-ignition efficiency and advanced compression.
