Ampaire has completed ground tests with its hybrid-electric propulsion system running on 100 percent sustainable aviation fuel (SAF). Dimensional Energy produced the ASTM D7566 fuel using a process involving electricity and carbon dioxide.

According to Ampaire, running its AMP-H570 AMP Drive powertrain on 100 percent SAF will act as a force multiplier in decarbonizing flights while offering the superior payload and range of a hybrid-electric system, as opposed to a battery-electric propulsion system. Both companies have received investments from Elemental Excelerator, and this connection led to the use of Dimensional Energy’s e-fuels with Ampaire’s technology in a move they say doubles the efficiency of SAF. The companies said the test results exceeded their expectations.
