As part of the Akvamarin project, Hungarian Gas Storage Ltd, in cooperation with four universities and a research institute, has installed a 2.5 megawatt electrolysis system and associated hydrogen gas production technology at the Kardoskút underground gas storage facility (Békés County).
The cost of the project was HUF 5.6 billion (EUR 15 million) and the state supported the development with HUF 2.5 billion (EUR 6.7 million).
Starting in September, Akvamarin Plus will be able to experiment with hydrogen reconversion to electricity and liquid storage and develop marketable processes.
