SwRI Granted $2Mn for Innovative Energy Storage R&D (Ind. Report)
Southwest Research Institute
Date: 2018-12-17
In the Lone Star State, the San Antonio-based Southwest Research Institute (SwRI) reports receipt of $2 million in grant funding from the US DOE Advanced Research Projects Agency-Energy (ARPA-E) to develop an advanced pumped heat electricity storage (PHES) system. This system offers twice the energy density of a lithium ion battery and is based on an innovative thermodynamic cycle to store energy in hot and cold fluids.

In this new system, electric energy from the grid is converted into thermal energy and stored as a thermal potential. At full capacity, the system can store energy for hours or up to several weeks before converting it back to electrical energy. The system can then provide greater than 10 hours of electricity at rated power. Tom adds that the capacity of the system can be easily extended by increasing the volume of the storage tanks. Additionally, this form of storage offers a low-cost solution when compared to the costs of operations like "peaker" plants, which generate and provide electricity during the peak demand hours of the morning, later afternoon and evening.
