Pratt & Whitney Awarded Department of Energy Project to Develop Hydrogen Propulsion Technology
Source: Pratt & Whitney Pratt & Whitney has been selected by the U.S. Department of Energy (DoE) to develop novel, high-efficiency hydrogen-fueled propulsion technology for commercial aviation, as part of DoE's Advanced Research Projects Agency-Energy (ARPA-E). The Hydrogen Steam Injected, Inter‐Cooled Turbine Engine (HySIITE) project will use liquid hydrogen combustion and water vapor recovery to achieve zero in-flight CO2 emissions, while reducing nitrogen-oxide (NOx) emissions by up to 80 percent and reducing fuel consumption by up to 35 percent for next generation single-aisle aircraft. "This truly is an exciting opportunity to start developing the key technologies that could bring the industry's first hydrogen steam injected, inter-cooled engine from concept to reality," said Geoff Hunt, senior vice president, Engineering and Technology, at Pratt [...]
