Corvus Energy, a global leader in zero-emission solutions for the maritime industry, has partnered with HD Hyundai Mipo to develop a green product tanker design that incorporates a carbon-free electric propulsion system. This innovative design, recently granted Approval in Principle by DNV, is based on using hydrogen from ammonia for zero-emission vessel propulsion. The system combines hydrogen fuel cell technology with an ammonia cracking process to extract hydrogen, resulting in only nitrogen and water vapor emissions when using green ammonia. The vessel design includes an 8.8MWh Corvus Pelican Fuel Cell System and a 2MWh Energy Storage System, setting a new standard for sustainable maritime transportation. HD Hyundai Mipo and Corvus Energy aim to deliver commercially viable, carbon-free vessel designs that prioritize safety, environmental standards, and innovation. DNV has reviewed the design to ensure compliance with safety and operational efficiency standards related to ammonia as a marine fuel, providing technical advice for further development. This collaboration represents a significant milestone in the journey to decarbonize the shipping industry and drive innovation towards a cleaner and more sustainable future.
