Rolls-Royce, Alder Fuels, Brazil BioFuels, Topsoe Advance in the Race to Net Zero Aviation
by Jim Lane (Biofuels Digest) … Meanwhile, Topsoe has been picked to support first sustainable aviation fuel-production in Brazil. Brasil BioFuels will build a new biorefinery to produce sustainable aviation fuel and second generation biofuel using Topsoe’s Hydroflex and H2bridge technologies. The new biorefinery will be built in Manaus, Brazil, and will have a production capacity of 500,000 tonnes per year The production is expected to start in 2025, using hydrotreated vegetable oil as a feedstock.
Topsoe’s hydroprocessing technology will allow the biorefinery to produce the low-carbon fuels while at the same time recycling gases and liquids from the process for production of hydrogen that will be integrated in the biorefinery’s operations.

Rolls-Royce accelerates in partnership with Alder
Meanwhile in the UK, Rolls-Royce has signed a Memorandum of Understanding with Alder Fuels to further test Alder’s Sustainable Aviation Fuel as it makes the critical next step on its journey to commercial scalability.
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.
…
The Alder technology backstory
Alder Fuels uses sustainable biomass such as regenerative grasses, forest residues and agricultural waste products to create low-carbon Alder Greencrude (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 Laboratory, can achieve greenhouse gas reductions of over 80 percent compared to fossil-based jet fuel.
