The Zero Emission Hyper Sonic Transport[1] or ZEHST is a supersonic passenger airliner project by EADS and Japan.[2] It can be seen as a descendant of the Concorde airliner.

Unveiled on 18 June 2011 by EADS at Le Bourget air show, it is projected to fly at Mach 4, 32 km above the ground,[3] carrying 50 to 100 people. It would combine three propulsion systems: two turbofans for take-off and up to Mach 0.8, then rocket boosters up to Mach 2.5, then two underwing supersonic ramjets would accelerate it to Mach 4. The plane is envisaged to be propelled by biofuel made from seaweed[1] and by oxygen/hydrogen.[3]

Using turbofans for take off would make ZEHST no more noisy than current-day ordinary planes. ZEHST is envisaged to fly by 2050 and would fly from London to Japan in less than 3 hours.
