Montana Renewables (MRL) has announced the opening of new onsite blending and shipping facilities. In partnership with Calumet Montana Refining (CMR), the facility now produces a 50/50 blend of renewable and fossil jet fuel (SAF). This blend is certified under ASTM D7566 and ASTM D1655 standards, ensuring it meets existing aviation fuel specifications.
The finished product, known as MaxSAF, is compatible with all current aircraft fueling systems. Initially, it will be distributed through AEG Fuels’ network to select airports in Montana, Washington, and Oregon. The first shipment of MaxSAF has already been sent, marking a significant step toward increasing the availability of SAF in regional markets.
Montana Renewables highlighted this milestone as part of its broader efforts to expand the use of bio-based fuels in aviation.
Landon Larson, Vice President at AEG Fuels, emphasized the importance of this collaboration. “Partnering with Montana Renewables on this inaugural SAF blend demonstrates how strategic alliances can accelerate the transition to sustainable aviation fuels,” he said. “This initiative provides valuable options for operators seeking to reduce their environmental impact.”
The development of this facility aims to support the growing market for bio-based jet fuels. Montana Renewables produces a range of renewable fuels, including SAF, renewable diesel, hydrogen, and naphtha. The company is one of only three producers operating at a commercial scale in North America dedicated to sustainable aviation fuel.
The introduction of MaxSAF offers multiple benefits. For Montana Renewables, it facilitates regional sales and expands market access outside major airports.
This initiative reflects ongoing efforts within the renewable energy sector to develop bio-based solutions that meet the increasing demand for sustainable aviation fuels and reduce reliance on traditional fossil fuels.
