| Project Name | Hydrogen Steam and Inter-Cooled Turbine Engine (HySITE) |
| Project Detail | Pratt & Whitney will design a novel, high-efficiency hydrogen-power turbomachine for commercial aviation. The Hydrogen Steam Injected Intercooled Turbine Engine (HySIITE) concept is intended to eliminate carbon emissions and significantly reduce nitrous oxide (NOx) inflight emissions for commercial single-aisle aircraft. The HySIITE engine will burn hydrogen in a Brayton (thermodynamic) cycle engine and use steam injection to dramatically reduce NOx. Via an innovative semi-closed system architecture, HySIITE aims to achieve thermal efficiency greater than fuel cells and reduce total operating cost compared with “drop in” sustainable aviation fuels. Potential Impact: This technology has the potential to achieve economical zero in-flight CO2 emissions and up to an 80% reduction in nitrogen oxides (NOx). |
