Successful H2Mare Symposium: Discussions and Insights on Offshore Hydrogen Production

On the second day of the Environment Week 2024, the tent for the H2Mare symposium: “More from the Sea: Green Hydrogen Made Offshore” was filled to capacity. Topics addressed included acceptance research and stakeholder involvement, technical prerequisites, regulations for offshore hydrogen production, as well as water management and environmental aspects.

The forum provided a platform for intensive exchanges between experts and the audience. Dr. Ursula Prall, Thomas Schwabe, Nardine Stybel, and Florencia Saravia, all experts in the field of green hydrogen, engaged with the curious audience. The event was moderated by Marlen Sunnyi Bohne, who skillfully guided the discussions and made the complex topics accessible to all participants.

Green Hydrogen: A Key to Tackling the Climate Crisis

The use of green hydrogen is considered a crucial factor in addressing the climate crisis. Given the increasing demand and the need to reduce emissions, importing green hydrogen in the early market ramp-up phase is seen as inevitable. The use of offshore-generated hydrogen offers a promising opportunity to produce energy sustainably and efficiently.

A compelling aspect discussed during the forum was the necessary integration and repurposing of existing LNG terminals to support the hydrogen market. In the TransHyDE forum “Hydrogen Imports and the Future of LNG Terminals,” Cäcilia Gätsch, Dorothea Müschenborn, Jan Hildebrand (NABU e.V.), Florian Gremme (RWE), and Elena V Timofeeva (Fraunhofer IEG) debated the challenges and opportunities associated with the transition from LNG to hydrogen infrastructure.

The Role of LNG Terminals: Challenges and Opportunities

LNG terminals, originally designed for the import and storage of liquefied natural gas, could potentially accommodate hydrogen in the future. However, this transition to "H2-readiness" is viewed as challenging. While it is commendable that the terminals are being prepared for hydrogen in the long term, the timeline for this conversion is critical. If an LNG terminal is not required to convert to hydrogen until 2044, this would be too late for the swift introduction of green hydrogen.

To allow LNG terminals to fulfill their intended role as a bridge to the hydrogen market ramp-up and thereby significantly contribute to the energy transition, additional incentives for earlier repurposing are needed. Under the current regulatory structure, there is a risk that a fossil lock-in effect could be exacerbated, where investments in fossil infrastructure are solidified long-term, delaying the transition to renewable energies.

Conclusion: Urgency and Perspectives

The discussions at the H2Mare symposium highlighted the opportunities associated with offshore hydrogen production. For a successful energy transition and effective climate protection, technical, regulatory, and societal challenges must be overcome. Particularly, the conversion of existing LNG infrastructure to hydrogen requires targeted incentives and accelerated implementation.

The Environment Week 2024 demonstrated that the path to a sustainable energy future is challenging but achievable. The engaged participation and insightful contributions from experts and panelists at the H2Mare symposium inspire optimism for the future, indicating that green hydrogen can significantly contribute to solving the climate crisis.
