Malta Announces Key Milestone for Pumped-Heat Energy Storage System Deployment

Malta Inc. announced that Southwest Research Institute has completed assembly and commissioning of the first-of-a-kind pumped heat energy storage (PHES) demonstration facility based on the utility-scale thermal energy storage system created by Malta as part of a project supported by a $2.6 million ARPA-E award from the U.S. Department of Energy.

Malta Inc. announced that Southwest Research Institute has completed assembly and commissioning of the first-of-a-kind pumped heat energy storage (PHES) demonstration facility based on the utility-scale thermal energy storage system created by Malta as part of a project supported by a $2.6 million ARPA-E award from the U.S. Department of Energy.

Long-duration, large-scale storage capabilities, like PHES, can help balance energy volatility and reliability issues caused by high market penetration of variable renewable energy resources such as solar and wind energy, and create solutions to fulfill worldwide carbon reduction goals.

 

PHES is a breakthrough for long-duration energy storage (LDES), repurposing conventional, commercially proven power plant equipment and processes to provide cost-effective, large-scale energy storage.

While the SwRI pilot is laboratory-scale, a full-size Malta PHES system will be able to store more than 100 megawatts (MW) of power for eight hours to eight days or longer (1,000+ MWh). The pilot will next be tested to demonstrate operation, verify system control strategies, and validate data.

"SwRI is a leader in advanced power systems and has pursued extensive PHES research. With the potential for high system performance and its ability to be built anywhere, PHES is an extraordinarily promising energy storage technology,” said Tim Allison, R&D Director of the Machinery Department at SwRI.

“SwRI has been a terrific collaborator in deploying this scaled, ‘pilot’ version of the Malta system,” said Malta CEO Ramya Swaminathan. “We look forward to leveraging this project to help further streamline this existing technology as Malta deploys commercial, similarly-integrated PHES systems in Europe and North America.”
