PARIS (Reuters) -A French technology startup unveiled plans on Wednesday to work with clean-aircraft venture JetZero to explore a potential hydrogen-powered variant of its futuristic all-wing design.

The move by SHZ Advanced Technologies is likely to rekindle a debate over the potential for zero-emission flight, six months after Europe’s Airbus put the brakes on plans to develop the world’s first hydrogen-powered airliner.

California-based JetZero aims to challenge the traditional duopoly of Airbus and Boeing by developing a so-called blended wing-body aircraft, which it claims will be able to cut fuel consumption – and therefore carbon emissions – in half.

JetZero and SHZ now plan to work together under a NASA research programme to design systems capable of storing and d
