Lhyfe, a green hydrogen producer invested in wind power offshoreis expanding its horizons by contributing to the reoxygenation of the oceans. In partnership with Flexens, a Finnish developer of hydrogen projects, and the Department of Ecology, Environment and Plant Sciences (DEEP) at Stockholm University, the project called Boxhy (Baltic Sea Oxygenation and the Super-Green Hydrogen Economy) aims to revitalize the Baltic Sea with oxygen.
Initiated in June 2020 with partners such as the Research Institute for Development (IRD) in Brest, the Boxhy project is based on deep oxygen injection (DOI). This method releases pure oxygen gas below the water surface, below the pycnocline, to rejuvenate marine ecosystems. Lhyfe thus intends to use the oxygen co-produced during the electrolysis of water, thus marking a further step in its quest for environmental innovation.
The oxygen demand below the pycnocline in the Baltic Sea and the Gulf of Finland is between 10,000 and 15,000 tonnes per day. Supported by the Science and Technology Advisory Committee (STACO), composed of nine global experts in oxygenation, the Boxhy project embodies Lhyfe’s commitment to marine sustainability and green hydrogen, marking a significant step forward in preserving ocean ecosystems.
