Chalmers researchers show possibilities of hydrogen-powered flight

In Sweden, the possibility of hydrogen-powered flight means greater opportunities for fossil-free travel, and the technological advances to make this happen are moving fast. New studies from Chalmers University of Technology, in Sweden, show that almost all air travel within a 750-mile radius (1200 km) could be made with hydrogen-powered aircraft by 2045, and with a novel heat exchanger currently in development, this range could be even further.  

Some of these technological advances can be seen inside the Chalmers wind tunnels, where researchers test airflow conditions in cutting edge facilities. Here, more energy-efficient engines are being developed that pave the way for safe and efficient hydrogen flight for heavy-duty vehicles. 

For this study, the researchers assumed a maximum flight distance of 750 miles and the use of an existing aircraft model adapted for hydrogen power. The study also showcased a new fuel tank that could hold enough fuel, was insulated enough to hold the super-cold liquid hydrogen and at the same time was lighter than today’s fossil-based fuel tank systems.
