Endesa Generación Portugal, part of Enel, has been award the connection rights to develop a renewable energy project combining solar, wind, green hydrogen and a 168.6MW battery energy storage system (BESS) to replace the country’s last coal station.
It’s been a positive week for thermal energy storage technology, with utility Edison International validating a cold storage solution, a collaboration between two groups to achieve 100% round trip efficiency, and an acquisition involving several intellectual property rights patents.
Long duration energy storage (LDES) technologies may have a difficult time competing with lithium-ion over the next decade as the latter’s cost-competitiveness at longer durations increases, possibly even to 24 hours, according to Haresh Kamath, Electric Power Research Institute (EPRI).
