Aviation has long been grappling with the challenge of decarbonization, but a recent breakthrough has sparked hope for a cleaner and more sustainable future. Universal Hydrogen, a pioneering company, has unveiled a revolutionary hybrid-electric regional aircraft propulsion system powered by hydrogen fuel cells.
Unlike traditional combustion engines, this innovative system utilizes hydrogen fuel cells, which operate silently and emit zero emissions. The ProtonExchange Membrane (PEM) fuel cell from Ballard generates up to 1 megawatt of electricity using liquid hydrogen as its fuel source. Paired with electric motors developed by magniX and an advanced battery system, this propulsion solution offers a perfect balance of endurance and power density.
One of the remarkable features of this hydrogen-powered engine is its efficiency. Fuel cells provide 2-3 times higher efficiency compared to traditional combustion engines. Moreover, liquid hydrogen, which is used as a fuel, is lightweight and offers higher energy density than jet fuel. This means extended flight times and increased payload capacity, making it suitable for regional aircraft up to the size of the De Havilland Dash 8.
More importantly, this new engine has the potential to revolutionize air travel as it emits only water vapor and warm air, eliminating carbon emissions. By harnessing the power of hydrogen fuel cells, Universal Hydrogen aims to achieve zero-carbon regional air travel within the next five years.
To put the technology to the test, the hydrogen aircraft engine underwent a ground-breaking trial at ZeroAvia’s facility in California. The test flight, conducted on a modified Dornier 228 aircraft, marked the first time a flight-weight hydrogen fuel cell powertrain with over 1 MW was tested in the air. During the 10-minute flight, the experimental engine successfully powered one wing while the conventional engine remained as a safety backup.
The successful test flight demonstrates the immense potential of hydrogen for aviation. As major manufacturers, including Airbus, show interest in this clean and sustainable technology, it becomes evident that hydrogen fuel cells can truly transform medium and long-haul air travel, ushering in a new era of emission-free flights across the globe.
