Efficient execution

The Alder Renewables team has operated at the cutting edge of renewable fuel production, as well as the technology development that underpins the clean energy transition. We are scientists, technologists, researchers, engineers, project managers, communicators, and commercial leaders.

The four ways we do it


Our proprietary platform converts abundant and sustainable biomass into low-carbon to carbon-negative Alder Renewable Crude (ARC). ARC can then be refined into low or even carbon-negative sustainable aviation fuel (SAF), other transportation fuels, including marine fuels, and renewable chemicals.


We partner with government, industry, and academics to advance the development of our technology. Alder Renewables is backed by Honeywell UOP, United Airlines Ventures, Directional Aviation, and Avfuel. Its technology has been trialed and tested at the Department of Energy’s National Renewable Energy Laboratory (NREL), with support from the U.S. Defense and Logistics Agency.


Our goal is to develop projects close to the source of sustainable biomass, rather than transporting the raw materials long distances from multiple sites back to one central facility. Our localized approach will allow us to bring direct socioeconomic benefits to local communities, reduce transport needs, and to be more capital and carbon efficient.


We advocate at the state, federal, and global level for government policy that can unlock the next generation of renewable fuels and chemicals, with a specific focus on unleashing the biomass supply chains and industry demand signals that will help to fast-track the clean energy transition.
