A subsidiary of German chemical company BASF will supply sodium-sulfur batteries to Korean power-to-gas (P2G) company G-Philos after the pair signed a memorandum of understanding (MoU) on 10 September.
Wholly owned subsidiary BASF New Business (BNB) will supply a total of 19.2MWh of sodium-sulfur(Na-S) batteries to G-Philos for P2G projects in Korea.
BNB distributes sodium-sulfur batteries produced by Japan firm NGK Insulators. The long-duration batteries are designed for stationary energy storage, with capability to discharge for 4–8 hours.
A 200kW Na-S battery system has been commissioned using G-Philos’ power conversion system (PCS). The green hydrogen electrolyser project was implemented in collaboration with Korea Midland Power (KOMIPO) at Sangmyung Wind Farm, South Korea.
The battery serves as an energy buffer between wind turbines and electrolysers to ensure stable hydrogen production from surplus wind power.
The MoU follows South Korea’s Green New Deal, which includes plans to invest KRW73.4 trillion ($61 billion) in projects, including renewable energy and hydrogen, as a part of its policy to transform into a low-carbon society. P2G technology is part of this plan.
