The legendary engine manufacturer Rolls-Royce is still working to reduce aviation’s carbon footprint. The business disclosed on Wednesday that it has inked a contract to test environmentally friendly aviation gasoline made by US-based Alder Fuels with a Rolls-Royce Pearl engine.
The testing outlined in the Memorandum of Understanding (MoU) inked by the two parties includes assessing the SAF made from Alder’s patented greencrude technology’s energy efficiency, emissions standards, and low-carbon credentials. This is produced using biomass, which is then transformed into aviation fuel that is, according to the company, “low-carbon to carbon-negative.” It is now being readied for a global rollout as a direct swap for aviation fuel derived from petroleum.
The private aircraft engine family from Rolls-Royce is called the Pearl engine. The Pearl 10X, created specifically to power Dassault’s brand-new flagship, Falcon 10X, is currently being developed. The deal with Alder Fuels was discussed by the SVP Strategy and Future Programmes.Business Aviation of Rolls-Royce
“To decarbonize medium- to long-haul air travel, the utilisation of Sustainable Aviation Fuel as a low-emission solution and its global commercial deployment are necessary. Rapid decarbonization is possible through this crucial pathway, however we are also working on electrification, hybrid-electric, and hydrogen technologies as long-term alternatives. We are moving forward on our path to net zero with our relationship with Alder Fuels, and we firmly support the UN Race to Zero target of 10% SAF use in aviation by 2030.”
Interest is growing in Greencrude
Alder Fuels produces low-carbon Alder Greencrude from sustainable biomass, including regenerative grasses, forest byproducts, and agricultural waste products (AGC). Using the infrastructure already present in bio and petroleum refineries, this can then be transformed into a drop-in SAF. The business has already partnered with Boeing, and United Airlines and Honeywell have each invested a significant sum.

“At Alder, our mission is to transform energy on a worldwide scale, and partnering is essential to realising this goal. Rolls-Royce, a leader in industrial technology and environmentally friendly aviation, will be instrumental in the decarbonization of the aerospace sector. Their name is a byword for superior engineering. In addition to being a significant step toward decarbonizing aviation, we anticipate that this partnership will strongly communicate to the market that the future of sustainable travel has arrived and that the time to make the switch is now.”
To support the performance of AGC-derived SAF as a drop-in substitute for conventional jet fuel and to produce crucial data for ASTM International’s development of a 100% SAF specification, engine testing will compare its performance to that of fossil-based jet fuel. The current SAF certification for all Rolls-Royce Trent and Business Aviation engines is for 50% SAF. By 2023, the corporation has committed to delivering complete SAF compatibility.
