In the UK, Boeing and Clear Sky are joining forces to accelerate sustainability solutions for aviation. As an initial project, the companies will help in testing and advancing Firefly Green Fuels’ technology to increase sustainable aviation fuel production in the UK. Firefly transforms sewage waste feedstock into SAF through hydrothermal liquefaction (HTL). This process uses heat and high pressure to convert waste into biocrude oil and biochar, a powdery substance that can be used as a fertilizer, Boeing said. The Clear Sky-led consortium of investors and strategic partners, including Boeing, will invest in Firefly’s new technology, subject to final diligence. Boeing will provide training, direction and facilitation on testing that will accelerate the qualification of this new route to SAF. “SAF offers the greatest opportunity to decarbonize aviation, and the industry’s collective challenge of bringing it to scale globally requires new sustainable pathways,” said Brian Moran, Boeing’s chief sustainability officer. “Clear Sky combines many years of investment expertise with knowledge on aviation’s decarbonization challenges. Firefly’s technology holds transformative potential as the SAF feedstock, sewage waste, is accessible in all regions of the globe.”
