Scotland's LoganAir, the largest regional airline, is collaborating with ZeroAvia to adopt hydrogen propulsion for commercial flights, aiming to achieve zero emissions. ZeroAvia, known for its hydrogen-electric engines, has partnered with LoganAir to integrate this technology into the airline's fleet. The initial focus will be on retrofitting a Cessna Caravan with ZeroAvia's 600-kilowatt system designed for smaller aircraft carrying 10-20 passengers. The partnership follows ZeroAvia's successful agreements with RVL Aviation and United Airlines, showcasing growing interest in hydrogen propulsion. ZeroAvia's engines utilize hydrogen fuel cells to drive electric motors, producing only water as a byproduct, aligning with LoganAir's sustainability goals. The company is pursuing certification for its hydrogen-electric systems for aircraft like the Twin Otter and ATR series flown by LoganAir. Despite challenges like higher fuel costs and system weight, hydrogen fuel cells show potential in reducing overall fuel consumption and maintenance costs. LoganAir's CEO expressed optimism about the partnership, emphasizing the airline's dedication to a cleaner future. The collaboration between LoganAir and ZeroAvia marks a significant step towards advancing sustainable air travel in Scotland and the UK.
