Elogen receives a certification from the Korean Gas Safety Corporation for the stacks used in its electrolysers

Elogen, a GTT company, announces the certification of its stacks, key components of its electrolysers for hydrogen production, by the Korean Gas Safety (KGS) Corporation. This certification, valid for three years, attests to the compliance of the products with the strict safety and quality standards set by the KGS, andthus demonstrating Elogen’s commitment to excellence.

Following the contracts signed with its Korean partner Valmax in 2023, Elogen has successfully completed the various stages of certification by the KGS, including a thorough audit of the design, production, and testing methods of its stacks. Compliance with the recent Korean standard KGS AC111, applicable to pressurized electrolysis stacks, was thereby demonstrated in terms of quality and safety. This recognition also paves the way for the continued commercial deployment of Elogen in the Korean market, known for its high standards of safety and reliability.
