Hydrogen-powered flight would offer new opportunities for fossil-free travel, and technological advancements in the field are moving fast. New studies from Chalmers University of Technology in Sweden indicate that by 2045, almost all air travel within a 750-mile radius could be made with hydrogen-powered aircraft. Additionally, with a novel heat exchanger currently in development, this range could be even further.

“If everything falls into place, the commercialization of hydrogen flight can go really fast now. As early as 2028, the first commercial hydrogen flights in Sweden could be in the air,” says Tomas Grönstedt, Professor at Chalmers University of Technology, and Director of the competence center TechForH2* at Chalmers.

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.

1. Hydrogen is decidedly NOT green and not clean. The belief in this is yet another example of greenwashing fossil fuels.

A Giant Climate Lie: When they're selling hydrogen, what they're really selling is fossil fuels.

One of the reasons we're observing what we're observing is general public disregard of the laws of thermodynamics, as the 2nd law of thermodynamics could be repealed by appeal to wishful thinking.

The laws of physics however are not subject to repeal.

2. I saw proposals for fat hydrogen airliners much like this fifty years ago.

Fancy color renderings and everything.

It was an absurd idea then as it is now.

If you've got some magical "green" energy source to make hydrogen you might as well go all the way and turn it into traditional jet fuel for use in ordinary jetliners.

Of course there is no magical source of green hydrogen. This is just another dodge by the filthy fossil fuel industry. They want to distract us with shiny things as the world burns.

Besides, there's already a high speed carbon-free transportation system for routes less than 750 miles that's a lot more comfortable and more convenient than flying. It's called a train.
