Overview
ZeroAvia develops hydrogen-electric propulsion for aircraft and focuses on retrofitting existing planes with a hydrogen-electric engine to cut emissions and operating costs. The engines run on green hydrogen produced via electrolysis and offer higher specific energy and lower maintenance costs than traditional jet engines, making them suitable for commercial aviation. The company targets retrofits that can cover most common flight missions—up to 300 nautical miles for small, 19-seat aircraft and up to 1000 nautical miles for larger 50-90 seat planes—thereby addressing 95%+ of today’s missions. This approach differentiates ZeroAvia from competitors by offering a retrofit path rather than building new aircraft from scratch, leveraging greener fuel and a cost-effective operating model, and aligning with global regulatory pushes toward net-zero emissions. The overarching goal is to make aviation substantially cleaner and steer the industry toward net-zero carbon emissions by 2050.

↑ 10%The largest battery-electric plane ever made has flown for the first time. Heart Aerospace's X1 demonstrator flew for 27 minutes on $5 of electricity Heart Aerospace has announced the successful first flight of its prototype all-electric aircraft, the X1 demonstrator. X1 took off from Plattsburgh International Airport in Upstate New York and flew for 27 minutes, reaching an altitude of 1,100 feet, running entirely on its batteries. Heart added the flight, including takeoff and landing, consumed less than $5 worth of electricity, a useful selling point given the price of fuel. It has already earned praise from executives at United Airlines and Air Canada, who are interested in adding electric planes to its fleets. If Heart is successful, the X1 will be followed by the ES-30, a fixed-wing 30-seat hybrid model designed to service regional airports. The company's hope is that its planes can offer a far cheaper service for hopper flights currently operated by turboprop planes like the Embraer ERJ. It is aiming for an all-electric range of 125 miles, with that figure climbing to 500 miles with the hybrid engine. Heart's broader pitch is that it won't just be in the cheaper cost of electricity versus jet fuel that will make its plane affordable. Naturally, the cheaper maintenance and operation cost of electric motors, their better reliability will add to the balance sheet. Of more concern, perhaps, is Heart's belief that the ES-30, while operated by a single pilot initially, will enable autonomous service in the future. Right now, the company is aiming for the ES-30 to enter service by 2031, a date Engadget, Inc.'ll only say is "ambitious" by most plane development standards. The next decade does appear to be one in which a number of aviation startups are looking to offer their vision for the future of flight. Heart will be jostling for space alongside Boom Supersonic, Harbour Air, ZeroAvia, and Rolls-Royce. But, as Engadget, Inc. opined back in 2021, the future of electric flight is entirely dependent on batteries getting a lot denser and lighter compared to their current-day equivalents.

ZeroAvia to lead project developing hydrogen refuelling network for commercial aircraft. ZeroAvia reports it is leading the Project Hydrogen Propulsion Refuelling Infrastructure Mobile Ecosystem (HyPRIME), a UK Department for Transport-supported project developing and demonstrating the hydrogen infrastructure needed to support future liquid hydrogen-powered commercial aircraft and zero-emission airport operations. The programme is integrated with ULEMCo's 'MATT' ground support equipment and GeoPura's Hydrogen Powered Unit 'HPU1'. "Demonstrated in a live airport environment, HyPRIME will evaluate the operational, safety and economic requirements for introducing and scaling liquid hydrogen across UK airport networks," says the company. "The project will generate critical insights into refuelling procedures, infrastructure, and the wider benefits of hydrogen adoption for aviation. A key objective is to demonstrate aircraft refuelling within standard commercial turnaround times. HyPRIME will capture and utilise hydrogen boil-off for hydrogen-powered ground support equipment and airport utilities and incorporate novel Helium-free inerting to reduce gas wastage, demonstrating an efficient and integrated hydrogen aviation ecosystem." By demonstrating how aircraft, ground vehicles and airport energy systems can operate together using hydrogen, HyPRIME will help lay the foundations for the future deployment of zero-emission airport operations and hydrogen-powered flight, according to ZeroAvia.
Birmingham and Bristol airports join ZeroAvia hydrogen infrastructure project. Last updated: 28 July 2026 12:28 Birmingham Airport will help test and build net-zero aviation technology as part of ZeroAvia's HyPRIME project (C) Damian Karpinski Birmingham Airport (BHX) will join zero-emission aviation developer ZeroAvia's project to develop and test a mobile liquid hydrogen refuelling vehicle to supply commercial hydrogen-electric aircraft and ground equipment, as well as generate power on-site. The Hydrogen Propulsion Refuelling Infrastructure Mobile Ecosystem (HyPRIME) project also includes zero-emission energy companies ULEMCO and GeoPura, as well as Bristol Airport. Zero-emission innovation. Discover more Air Travel Poker & Casino Games The HyPRIME project is one of eight projects to receive funding from the United Kingdom (UK) Department for Transport (DfT) as part of several initiatives to support the transition to zero-emission aviation. The DfT funds 62% of the HyPRIME project's costs, amounting to £2,124,651. On Feb. 20, 2023, ZeroAvia and Birmingham Airport announced a long-term partnership to develop on-airfield hydrogen refuelling capabilities and zero-emission passenger flights. Tom Denton, head of sustainability at Birmingham Airport, said: "Hydrogen electric aircraft are progressing quickly, and airports need to understand how this fuel can be safely and efficiently integrated into daily operations. HyPRIME gives us the opportunity to test procedures and build the knowledge required to support future zero emission flights from Birmingham. Taking part in this project helps us maintain the momentum we've built over the past few years and moves us that little bit closer to achieving our mission of running a lower carbon airport." UK airports' zero-emissions goal. Discover more Recreational Aviation Low Cost & Last Minute Travel Birmingham Airport announced an 11% reduction in its location-based greenhouse gas emissions in 2025/26 and targets a 60% reduction in airport-controlled emissions by the end of 2026, as part of its commitment to net-zero operations by 2033. Similarly, Bristol Airport aims to reduce its carbon emissions by 73% by 2027, with the goal of achieving net-zero operations by 2030. The mobile liquid hydrogen refuelling vehicle built by the HyPRIME project can be an important step in supporting the use of hydrogen-electric aircraft by providing on-site means to refuel jets within commercially relevant timeframes and costs, without committing to a permanent hydrogen refuelling infrastructure.
