The Exeter Port Authority has embarked on a green initiative by introducing a hydrogen electric boat, MV Dirac, for trials on the Exe Estuary. Designed by Ecomar Propulsion, the boat is powered by two 250kW Ecomar Kairos motors and features 180kWh of Li Ion Batteries supplemented by a hydrogen fuel cell, allowing for a considerably extended range. The innovative aspect lies in the use of hand-portable BOC Genie bottles to supply hydrogen, making refueling convenient and eliminating the need for installing expensive equipment at the port. Collaborating with Exeter University's Centre for Clean Future Mobility, the project aims to gather data during an extended trial period to showcase the ease and safety of transitioning to clean maritime practices. The initiative is a testament to British engineering and innovation, positioning the UK as a leader in decarbonizing waterways. With less than 50 hydrogen vessels globally, MV Dirac represents a significant step towards a carbon-free future for boats. The project has garnered positive support from various stakeholders, including Exeter City Council and the Harbour Master, emphasizing the importance of such initiatives in achieving sustainability goals. The collaboration aims to spark a two-way dialogue with communities, debunking common misconceptions about range and safety in hydrogen-powered vessels. As the trial progresses, the Ecomar team plans to upgrade and modify systems to ensure MV Dirac can handle tasks performed by combustion-powered boats. Overall, the trial of MV Dirac signifies a crucial milestone in the maritime industry's transition towards clean energy propulsion. The project's positive reception and collaborative efforts underline the commitment to sustainable and innovative solutions for marine transportation, setting a precedent for future advancements in the sector.
