SWITCH Maritime, in collaboration with LH2 Shipping and LMG Marin, has announced plans to embark on the construction of the first liquid hydrogen-fueled ferry in the United States. The project involves the transformation of the existing RoPax vehicle ferry, MF Hydra, which is currently operational in Norway. Following the successful launch of the hydrogen-powered ferry Sea Change in the US, SWITCH Maritime is eager to progress towards their next zero-emission vessel initiative. The Sea Change, a 75-passenger catamaran ferry, has already begun public service in the San Francisco Bay Ferry system after meeting regulatory requirements from the US Coast Guard. The vessel utilizes electric motor propulsion and fuel cells powered by gaseous hydrogen storage. As a step towards larger vessels, SWITCH is working on a 150-passenger catamaran with plans for a 300+ passenger ferry in the future. The shift from gaseous to cryogenic liquid hydrogen storage is seen as a strategic move by SWITCH to accommodate larger vessels and increased energy demands. The RoPax vehicle ferry, designed for the US market, will operate using liquid hydrogen that is vaporized onboard to generate electricity for the fuel cells, ensuring a sustainable and efficient power source. This transition aligns with the International Code of Safety for Ships using Gases or other Low-flashpoint Fuels (IGF Code), establishing a regulatory framework for safe hydrogen fueling in the maritime sector. By opting for liquid hydrogen, SWITCH aims to streamline fueling processes and reduce the need for continuous refueling, offering a promising solution for long-term maritime operations. The innovative approach of using liquid hydrogen as a marine fuel showcases a commitment to green technology and sustainability within the maritime industry, setting a new standard for eco-friendly vessels in the US. With a focus on compliance, safety, and efficiency, SWITCH Maritime is poised to lead the way in integrating hydrogen propulsion systems into the future of maritime transportation.
