Green Marine UK's ambitious Project Verdant aims to revolutionize the maritime industry by retrofitting Crew Transfer Vessels (CTVs) with advanced technologies such as hydrogen fuel cells and batteries to reduce emissions while servicing offshore wind farms. This groundbreaking initiative has received Approval in Principle from RINA, marking a significant milestone in the project. The project's first phase, which includes a preliminary design and feasibility study, has been successfully completed, paving the way for further development phases involving design, engineering, and sea trials. The innovative design of Project Verdant integrates hydrogen fuel cells with electric motors to achieve zero-emission operation, particularly during low-speed operations at offshore wind farms. By collaborating with leading experts like Energys and Engineered Marine Systems (EMS), the project aims to achieve a substantial reduction in CO2 and NOx emissions, offering a promising solution to the industry's decarbonization challenges. With projections indicating a growing demand for offshore support vessels in the renewable energy sector, Project Verdant's approach aligns with the industry's transition to Net Zero, aiming to enhance vessel redundancy and flexibility. The project's success not only promises environmental benefits but also economic advantages, as demonstrated by the insights provided by EMEC on economic modeling and hydrogen logistics. The recognition received by key team members, such as Roberto Tuda from Waves Group, underscores the industry's acknowledgment of the project's significance in driving decarbonization efforts. Through collaborations with industry leaders and regulatory bodies, Project Verdant sets a new standard for environmental responsibility in offshore services, offering a scalable and sustainable model for integrating hydrogen technology into maritime operations.
