Using deep oxygen BOxHyImage Source: SteelGuru Synopsis The BOxHy project, a joint effort by Flexens, Lhyfe, and Stockholm University, aims to combat anoxia in the Baltic Sea. Using deep oxygen injection and green hydrogen production, they plan to rejuvenate marine ecosystems. This pioneering initiative targets to eliminate anoxia, fostering marine health, and harnesses hydrogen production to fund Baltic Sea restoration. Article: A groundbreaking collaboration, the "BOxHy" project, brings together Flexens, Lhyfe, and Stockholm University to address the severe issue of anoxia in the Baltic Sea. This venture, launched in October 2023 and slated to conclude in October 2024, endeavors to counter the dire lack of oxygen in the marine environment through innovative methods. Anoxia, characterized by a complete absence of oxygen in the Baltic Sea, poses a significant threat to marine life. The project's primary objective revolves around introducing oxygen into the sea via tailored technology, aiming to identify suitable coastal areas for a pilot study while exploring opportunities to couple this endeavor with green hydrogen production. Deep Oxygen Injection (DOI), a method involving the release of pure oxygen deep below the water's surface, is central to the project. This technology, leveraging micro-bubbles to distribute oxygen evenly, has demonstrated success in freshwater lakes in the United States. The project seeks to identify a fitting fjord-scale pilot site for DOI and commence preparatory measures, including stakeholder engagement and sourcing potential funding channels. The ecological implications of this venture are promising. Restoring Baltic Sea oxygen levels can significantly expand habitats for marine life, enhancing conditions for cod reproduction and feeding. Additionally, this restoration effort could potentially reduce phosphorus concentrations and mitigate the proliferation of toxic cyanobacteria. BOxHy takes a novel approach, integrating the burgeoning green hydrogen sector with Baltic Sea restoration. This strategy envisions utilizing oxygen co-produced during hydrogen electrolysis to aid in the rejuvenation of marine ecosystems. This super-green hydrogen production emerges as a potential financial contributor to the Baltic Sea Oxygenation initiative. The project's coordinators from Flexens emphasize their commitment to manage and navigate the multifaceted landscapes essential for the initiative's success. Engaging key stakeholders, investigating energy supply availability, and mapping potential connections with anoxic regions are integral to their role. Lhyfe, a major player in renewable hydrogen production, brings valuable experience to the table. Their prior offshore hydrogen production projects demonstrate potential integration with DOI technology in the Baltic Sea environment Stockholm University's DEEP department, with extensive Baltic Sea research, spearheads the evaluation of coastal bays for oxygenation tests and assesses anoxic areas and oxygen addition requirements. The project is supported by a Science and Technology Advisory Committee, aiming to bridge knowledge gaps and enhance possibilities in oxygenation. Conclusion The BOxHy initiative, uniting Flexens, Lhyfe, and Stockholm University, pioneers solutions against anoxia in the Baltic Sea. By injecting oxygen and linking it to green hydrogen production, the project aims to revitalize marine ecosystems. This innovative approach signals hope for restoring Baltic Sea health and underscores hydrogen's potential in funding ecological initiatives.
