A U.K.-backed research group unveiled a design for a liquid hydrogen-powered airliner theoretically capable of matching the performance of current midsize aircraft without producing carbon emissions. The FlyZero concept envisions a plane carrying 279 passengers non-stop from London to San Francisco at the same speed and comfort as today, the Aerospace Technology Institute said in a statement Monday. The group, a partnership between the U.K. government and industry, is meant to accelerate high-risk projects that will benefit home-grown firms. Hydrogen propulsion is seen as one of the most promising technologies for achieving carbon-neutral commercial flights. However it’s expensive and more challenging to store on board, and it will take years to develop the planes and build infrastructure such as airport refueling capacity. The U.K., which hosted the COP26 climate summit last month, is funding new technologies to help create aerospace jobs while meeting its climate targets. The government has […]
