Alfa Laval has achieved Approval in Principle (AiP) from DNV for its Gas Combustion Unit (GCU) technology designed for handling hydrogen boil-off gas on liquid carriers. The AiP validates the technical feasibility and safety features of the GCU, which is essential for managing the boil-off gas from liquid hydrogen carriers. With restrictions on venting cargo, a GCU is necessary to control tank pressure and temperature to safely combust hydrogen boil-off gas. This milestone paves the way for the development and testing of a GCU prototype to ensure a secure and effective system for handling boil-off gas on liquid hydrogen carriers. Alfa Laval's Business Development Manager, David Jung, highlighted the significance of the AiP as a testament to their adherence to safety standards and DNV's classification rules. The challenges of transporting hydrogen, with its extremely low boiling point and unique properties, emphasize the importance of prioritizing safety in developing technologies like the GCU. Jung emphasized the critical role of ensuring safety and reliability in enabling technologies for hydrogen transportation. Alfa Laval's experience in gas combustion technology for LNG carriers positions them well to address these challenges and contribute to the safe transport of hydrogen in the future.
