Rolls-Royce and Alder Fuels join forces to fuel race to net-zero

news item image
Rolls-Royce has signed a memorandum of understanding (MoU) with Alder Fuels, a clean tech developer and green crude producer to further test sustainable aviation fuel (SAF). The SAF, which has been produced based on Alder Fuels’ proprietary technology, is being readied for global rollout as a drop-in replacement to petroleum-based jet fuel.
The testing, which will include flight tests on a Rolls-Royce Pearl engine, will evaluate the energy efficiency, emissions criteria, and low-carbon credentials of the SAF produced from Alder Greencrude (AGC).
Frank Moesta, SVP strategy and future programmes – business aviation, Rolls-Royce, said, “The use of SAF as a low-emission solution and its global commercial deployment are essential to the decarbonisation of medium to long-haul air travel.
“While we are also working on electrification, hybrid-electric and hydrogen technologies as long-term alternatives, rapid decarbonisation is within reach through this critical pathway. Through our partnership with Alder Fuels, we are taking the next steps on our journey to net zero and are committed supporters of the UN Race to Zero goal of 10% SAF use across aviation by 2030.”
“At Alder, we are on a path to transform energy on the global stage and partnership is key to our vision. As a pioneer in both industrial technology and sustainable aviation, Rolls-Royce will play a leading role in decarbonising the aerospace industry. Their name is synonymous with the best of engineering,” said Bryan Sherbacow, president and CEO of Alder Fuels.
“Our hope is that this collaboration will not only mark an important milestone for the decarbonisation of aviation, but that it will send a strong global signal to the market that the future of sustainable flight is here and the time to transition is now.”
Alder Fuels uses sustainable biomass such as regenerative grasses, forest residues and agricultural waste products to create low-carbon AGC that can be converted into a drop-in SAF using existing bio and petroleum refinery infrastructure.
The process, which has been developed in close partnership with the US Department of Energy’s National Renewable Energy Laboratory, can achieve greenhouse gas reductions of over 80 percent compared to fossil-based jet fuel.
Rolls-Royce has previously committed to ensuring all its Trent and business aviation engines are compatible with 100% SAF by 2023.
