MV Dirac: Trialling a Hydrogen-Electric Boat in Exeter
Key Ideas
- The Exeter Port Authority is testing a new hydrogen-electric boat named MV Dirac on the Exe Estuary to evaluate its performance and viability.
- The boat, designed and manufactured by Ecomar Propulsion, features two 250kW Ecomar Kairos motors, 180kWh of lithium-ion batteries, and a hydrogen fuel cell for extended range.
- The trial is supported by Exeter University's Centre for Clean Future Mobility to gather data and demonstrate the potential of clean maritime technologies.
- The goal is for MV Dirac to handle the same workload as traditional combustion-powered boats by the end of the trial, with further upgrades and modifications planned.
The Exeter Port Authority is conducting a trial of a new hydrogen-electric boat, the MV Dirac, designed and manufactured by Ecomar Propulsion. The vessel, named after physicist Paul Dirac, is undergoing testing on the Exe Estuary to assess its performance and viability. Equipped with two 250kW Ecomar Kairos motors, 180kWh of lithium-ion batteries, and a hydrogen fuel cell, the boat aims to showcase the potential of clean maritime technologies. The hydrogen fuel is stored in portable BOC Genie bottles, allowing for easy recharging onboard. The trial is being supported by Exeter University's Centre for Clean Future Mobility to address concerns about range and safety. The Harbour Master highlighted the simplicity of hydrogen refueling, emphasizing its ease and cost-effectiveness. The ultimate goal is for MV Dirac to handle the workload of traditional boats, with plans for upgrades and modifications during the trial period.
