Hydrogen-Powered Airliners — What Are The Possibilities?

I t is clear that all-electric aircraft’s feasibility in the airlines on a mass scale is still some time ahead of us, as the current battery and motor technologies are not up to the task of flying in the flight levels with hundreds of passengers. With current battery technology, the battery pack required would take up most of the space and weight limitation of an airliner. However, hydrogen-powered aircraft are another story. In this week’s On Aviation™ Digest, we will take a look at some articles relating to hydrogen-powered aircraft, their current development, and their possible application as airliners.

The Hydrogen Revolution In The Skies

A record-breaking commercial-scale hydrogen plane has taken off in the UK, with more set to join it soon. How far can such planes go in cutting the aviation industry’s emissions?

Large Hydrogen-Powered airliners Could Be In Service By 2030

In May 2021 Clean Sky 2 published its first Technology Evaluator1. One of its main conclusions is that “the main focus on decarbonising aviation should be on short-range aircraft flying distances of less than 4,000km, however with much larger passenger capacity, well over 300, even over 400 passengers in the cabin. This type of aircraft does not exist today.” This article, however, will show that the ideal type of aircraft almost exists now if liquid hydrogen is the preferred fuel.

A New Hydrogen Plane Can Fly Halfway Around the World Without Refueling

A U.K. government-backed research firm, Aerospace Technology Institute (ATI), revealed a new liquid-hydrogen-powered airliner concept called FlyZero. In theory, this 279-seater aircraft will have the same performance capability as a traditional midsize aircraft, but without producing carbon emissions, the ATI says in a press release.
