Flexens, Lhyfe, and the University of Stockholm have unveiled the findings of the BOxHy * project. This initiative evaluates the feasibility of injecting oxygen generated during hydrogen production via water electrolysis to combat the “asphyxiation” of the Baltic Sea.

The BOxHy project, which we’ve covered previously, focuses on reoxygenating the Baltic Sea, a solution validated by the United Nations. Through an in-depth scientific study, 19 coastal sites were analyzed, and three were identified as ideal candidates for a pure oxygen injection pilot project. These selections were based on around ten specific criteria.

The proposed pilot project, code-named BOxIn (Baltic Sea Pilot for Pure Oxygen Injection), is planned to span approximately six years. This timeframe includes an initial period for baseline measurements, at least three years of oxygen injection, and an additional year of post-experiment observation. The initiative will require an estimated budget of €5–6 million. Key factors like the project’s final location, scope, and duration will depend on the level of funding secured.

The BOxHy project represents a groundbreaking step in leveraging hydrogen production byproducts to address ecological challenges. The success of BOxIn could provide valuable insights into combating marine hypoxia and contribute to global sustainability efforts.
