GE Aerospace has received a $4.5 million grant from the Advanced Research Projects Agency–Energy (ARPA-E) to develop a small prototype engine that will combine fuel cells with the use of a gas turbine powered by sustainable aviation fuel (SAF).

The project is Phase 2 of the engine maker’s FLyCLEEN program. According to GE's engineers, the use of solid oxide fuel cells in the 25kW hybrid-electric unit “could vastly improve the efficiency of converting the chemical energy from SAF into electric power and move closer to net-zero CO2 emissions.”
