Swiss aviation pioneer Bertrand Piccard is developing a plane powered by liquid hydrogen after a much-hyped flight in 2015 ...

in hopes of heading toward greener commercial flight than that of fossil fuel-powered planes today - this time using super-cold liquid hydrogen. Climate Impulse is a project that was started last ...

The push to develop hydrogen-powered planes was once a key part of the aviation industry’s bid to eliminate carbon emissions. But in the last few weeks, it has fallen suddenly and dramatically ...

Arlington-based startup Eviation, which in 2022 flew the first flight of its electric airplane at Moses Lake, laid off most staff and paused operations indefinitely.

in hopes of heading toward greener commercial flight than that of fossil fuel-powered planes today — this time using super-cold liquid hydrogen. From a workshop on France's Atlantic coast ...

Now, the 66-year-old Swiss adventurer behind Solar Impulse is aiming higher, in hopes of heading toward greener commercial flight than that of fossil fuel-powered planes today - this time using ...

The controlled release of liquid hydrogen from ultra-insulated tanks under the airplane's wings causes it to heat into a gas, a bit like how pressurized water vapor powered 19th-century steam engines.

Many governments want to produce more green hydrogen, but for now, the world can't make enough clean electricity for power needs on land, let alone to generate enough for wide-scale use by planes ...
