The BOxHy project, a collaboration between Flexens, Lhyfe, and the Department of Ecology, Environment, and Plant Sciences (DEEP) at Stockholm University, has achieved a significant milestone by being endorsed under the United Nations Decade of Ocean Science for Sustainable Development 2021-2030. This project aims to combat anoxia in the Baltic Sea, caused by oxygen loss due to human-induced factors like water pollution and global warming. By injecting oxygen into the sea through offshore hydrogen production using water electrolysis, the project seeks to restore aquatic vitality and explore green hydrogen production, offering a sustainable model for environmental restoration and economic development. The UN endorsement validates the project's commitment to sustainable ocean governance and its alignment with the 2030 Agenda for Sustainable Development. BOxHy's future plans include expanding stakeholder engagement, implementing the Baltic Sea Pilot for Pure Oxygen Injection (BOxIn), and collaborating with international partners to mitigate anoxia on a Baltic-sea-wide scale, emphasizing global collaboration and innovation for ocean health.
