Insights
Montana Renewables began commercial 50/50 SAF blending and local distribution on
Montana Renewables and Calumet Montana Refining commissioned onsite blending and shipping to supply a nominal 50/50 renewable/fossil jet blend certified to ASTM D7566 and ASTM D1655. The product is described as drop-in compatible and will initially move via AEG Fuels to select hubs in Montana, Washington, and Oregon, enabling local truck-rack sales and regional service.
The primary dependencies are operational throughput at the Great Falls site, ongoing ASTM-compliant fuel quality, and the commercial rollout through AEG Fuels' network; each factor determines near-term uptake. Risks include limited initial geography and the need for consistent feedstock supply, which the release names (tallow, distillers corn oil, canola, used cooking oil, camelina) as sources.
Concrete items to watch: first commercial shipping volumes from the truck rack, confirmations of deliveries to the named Pacific Northwest hubs, and any public sales metrics or offtake agreements in the next several months. These milestones will clarify whether the launch meaningfully expands regional SAF availability and revenue streams for Montana Renewables.
This finished product is drop-in compatible with all existing systems and will initially be distributed through AEG Fuels' network to select aviation hubs in
