Pratt & Whitney's Hydrogen Steam Injected, Inter‐Cooled Turbine Engine (HySIITE) concept is designed to take full advantage of the cryogenic properties of liquid hydrogen fuel, using water vapor recovery and steam injection technology to enable up to a 35% improved energy efficiency, compared to a current state-of-the-art single aisle propulsion system. As part of a project supported by the U.S. Department of Energy’s ARPA-E program, rig tests conducted by Pratt & Whitney demonstrated the potential to reduce NOx by up to 99.3% and capture one gallon of water every three seconds from the engine exhaust.
RTX is the world's largest aerospace and defense company. With more than 185,000 global employees, we push the limits of technology and science to redefine how we connect and protect our world.
