H2TC, led by Nabil Bennouna of Climate Aligned Industries, envisions a 'green tunnel' that metaphorically connects the US Gulf Coast to Europe to transport renewable hydrogen derivatives. This initiative is part of a global race towards renewable hydrogen, with H2TC targeting to deliver 3 million metric tons annually by 2030, establishing a vital transatlantic clean energy corridor. The project recognizes ammonia as the preferred carrier for hydrogen due to its energy density, cost efficiency, and compatibility with existing infrastructure. With industry giants like Shell and Linde onboard, H2TC is working to overcome regulatory and technological challenges, advancing the global hydrogen supply chain. Aligning US-EU trade laws and establishing standardized market practices are central to H2TC's goal of a seamless transatlantic clean hydrogen trade tunnel. The recent US Inflation Reduction Act, offering tax credits up to $3 per kilogram of hydrogen, has accelerated hydrogen production, making the green hydrogen pipeline to Europe economically feasible. Leveraging existing infrastructure along the Gulf Coast, including pipelines, storage facilities, and ports, forms the foundation of the hydrogen tunnel, enabling cost-efficient large-scale transportation to Europe. Bryan Fisher of RMI emphasizes the project's potential to ensure energy security and facilitate the decarbonization of economies globally, serving as a model for renewable energy trade. H2TC plans its inaugural hydrogen shipment in 2026, heralding the commencement of a transatlantic energy revolution and setting the stage for decarbonizing global systems.
