Green Marine UK has received approval in principle (AiP) from RINA for its maritime initiative, Project Verdant, aimed at retrofitting crew transfer vessels (CTVs) with hydrogen fuel cells and batteries to reduce emissions while servicing offshore wind farms. The first phase involving a preliminary design and feasibility study has been completed successfully, paving the way for subsequent project phases. The hybrid system proposed by Project Verdant could significantly cut CO2 emissions by up to 30% and NOx emissions by up to 40%, particularly beneficial when CTVs operate in loiter mode for extended periods. Led by Managing Director Jason Schofield, the project aims to ensure safe operation in UK waters in line with regulations. The approval marks a milestone in the wind industry towards achieving greener service maintenance. With support from Innovate UK, Waves Group, and EMEC, the initiative also involves Energys and Engineered Marine Systems (EMS) for design and engineering. Projections suggest a growing need for vessels in the offshore support sector, making the adoption of hydrogen technology crucial for realizing sustainability goals and transitioning to net zero emissions by 2050.
