ZeroAvia, a UK-based company with headquarters in California, is making significant strides in the development of hydrogen-electric jet engines. The company recently raised $34 million in funding, with support from big players like American Airlines, Airbus, and Alaska Airlines. This investment is part of an ongoing effort to advance aviation technology and shift towards more sustainable practices. ZeroAvia's focus is on creating engines that support a 300-mile range for smaller aircraft and eventually expanding to a 700-mile range for larger planes. The company's engines utilize hydrogen in fuel cells to generate electricity, with the only byproduct being water during flight, promoting environmentally friendly aviation. With almost 2,000 pre-orders already in place from various airlines, operators, and manufacturers, ZeroAvia is poised for growth. The company has been actively testing prototypes and key components, including a successful test on a Dornier 228 aircraft in the UK. In addition to further engine development, ZeroAvia is considering establishing a manufacturing facility in the UK to support production. This move aligns with the company's vision to revolutionize the aviation industry with innovative and sustainable technology. The funding boost and partnerships with industry leaders position ZeroAvia as a key player in the future of eco-friendly air travel.
