OEMs were equally quick to accelerate development of more environmentally-friendly products. The current emphasis is on propulsion systems that are powered by clean-burning sources – electricity, hydrogen, and sustainable aviation fuel (SAF.) Interest in biofuel started years ago The move to SAF, in particular, is gaining the most momentum, yet research on SAF viability production started some two decades ago. Then, biofuels produced from plant matter offered
