Alfa Laval has received Approval in Principle (AiP) from DNV for its Gas Combustion Unit (GCU) designed for liquid hydrogen carriers.
This approval confirms the GCU’s technical feasibility and safety features, crucial for managing boil-off gas (BOG) from hydrogen storage tanks. The AiP marks a significant milestone, enabling Alfa Laval to proceed with developing a prototype for further testing and type approval.
The GCU is essential for liquid hydrogen carriers due to the challenges associated with hydrogen’s extremely low boiling point of -253°C, which results in a higher boil-off rate compared to LNG. Hydrogen’s flammability and ignitability require meticulous safety measures in the GCU design.
According to the company, Alfa Laval’s experience with LNG GCU technology, which has seen over 200 installations, provides a foundation for adapting the technology to hydrogen. The AiP underscores the company’s capability to ensure safe and efficient hydrogen transportation.
David Jung, Alfa Laval’s Business Development Manager, highlighted that the AiP demonstrates adherence to DNV’s classification rules and safety standards, reinforcing the company’s position in the hydrogen transportation market.
The proven LNG GCU technology offers a strong base, but adapting it to hydrogen’s unique properties involves crucial adjustments to ensure operational safety and efficiency, Alfa Laval explains.
