Swedish marine technology company Alfa Laval has achieved a major milestone by securing Approval in Principle (AiP) from DNV for its gas combustion unit (GCU) technology designed for managing hydrogen boil-off gas. This development allows Alfa Laval to implement the GCU on liquid hydrogen carriers, enhancing the safety of hydrogen transportation. The AiP represents a crucial step towards the creation of a GCU prototype that will undergo testing and approval to ensure a secure and efficient system for handling hydrogen gas. The challenges of utilizing hydrogen as a marine fuel are acknowledged, including its limitations with deep-sea vessels and the complexities of transportation due to its unique properties. Alfa Laval's GCU technology is essential for maintaining safe tank conditions on liquid hydrogen carriers by regulating pressure and temperature for the controlled combustion of hydrogen gas. David Jung from Alfa Laval emphasized the importance of ensuring the safety and reliability of technologies in hydrogen transportation. Alfa Laval's experience in LNG GCU technology and their collaboration with Shell International Trading and Shipping Company showcase their preparedness for the growing hydrogen transportation market.
