Rondo Energy, a US maker of electric thermal energy storage systems, has signed a memorandum of understanding (MoU) with Saudi Arabian Oil Company (TADAWUL:2222), for the potential installation of up to 1 GWh of its heat battery technology. The companies are working on engineering plans for a first industrial-scale deployment of Rondo Heat Batteries to reduce emissions from Aramco’s facilities.
