Isentropic

James Macnaghten will take part in the Rising Stars Roundtable on Monday, 26 April, where he will discuss Isentropic's pumped heat electricity storage technology (PHES).

Isentropic's revolutionary PHES technology has the potential to dominate the large-scale electrical energy storage market and, by providing a cost-effective solution to the intermittency problems of renewable energy sources, represents a key enabling technology for their widespread adoption.

"Our technology has no geographical constraints, is compact and can demonstrate a round trip electrical efficiency of 72% to 80%," explains Macnaghten. "We are also able to demonstrate a build cost of $10 per kWh for a utility-scale application, which is the lowest cost of any storage technology, including battery and pumped hydro."

Isentropic's system is a highly reversible, gas cycle machine that works as both an engine and a heat pump. It is the first time that a reversible system has been developed both to store and recover electricity using a thermodynamic approach.

Macnaghten says that the Lux Executive Summit "is a great opportunity for the players in the emerging energy and environmental sectors to meet and build relationships with potential partners."
