Hanwha Aerospace, in collaboration with SK Enmove, has unveiled the world’s first immersion cooling Energy Storage System (ESS), marking a significant step toward non-flammable battery technology. This partnership is set to drive innovation and revolutionize the ESS market with safer, more sustainable energy storage solutions, bolstering South Korea’s leadership in green energy storage.
The newly developed immersion cooling ESS uses advanced thermal fluid technology to fill the lithium-ion battery modules, effectively isolating each cell. This innovative design prevents the spread of thermal runaway, even if a single cell experiences this issue, and addresses other safety risks such as insulation failures due to environmental factors like dust or salt.
Commenting on the development, Seung-hyun Son, Head of Energy Systems Center at Hanwha Aerospace, said, “With decades of experience in ESS design and R&D, we have achieved industry leading levels of safety. Our immersion cooling ESS is set to lead the next generation of energy storage solutions, ensuring the highest levels of fire prevention. Safety is a critical requirement for maritime ESS applications.”
By offering superior safety compared to conventional air- and water-cooled ESS models, the system enhances the non-flammable characteristics of the battery. It has received certifications from major global institutions, including DNV and the Korean Register of Shipping (KR), for its key model, SEAL.
SK Enmove, Hanwha Aerospace’s partner providing thermal fluids for the immersion cooling ESS, also presented its differentiated fluid technology.
