MUMBAI, India, Sept. 22 -- Intellectual Property India has published a patent application (202547084606 A) filed by Supercritical Storage Company, Inc. on September 05, 2025, for Waste Heat Integration Into Pumped Thermal Energy Storage.
Inventors include Mallinak, Jason A.; Held, Timothy J.; and Milller, Jason D..
The application for the patent was published on September 18, 2026, under issue no. 38/2026.
Abstract: Disclosed herein is a technique by which the round-trip efficiency ("RTE") of a pumped thermal energy storage system may be increased without significantly negatively impacting the performance of either the heat engine or the heat pump at the expense of the other. More particularly, the technique, the technique does not boost the coefficient of performance ("COP") for the heat pump at the expense of the thermal efficiency (?) of the heat engine and vice-versa. The disclosed technique accomplishes this by using a low-temperature thermal reservoir during the charging process that is at a higher temperature than the generating cycle's low-temperature thermal reservoir. The low-temperature thermal reservoirs are "decoupled", in that their temperature and utilization are independent of one another.
