## Summary

CleanJoule maintains a public website at cleanjoule.com describing its biomanufactured sustainable aviation fuel (CycloSAF) and rocket propellant (SpaceSAF) products. The company's public materials describe a feedstock-flexible biochemical process producing fuels with higher energy density than petroleum-derived equivalents. Business Wire press releases from December 2024 and January 2025 document the SpaceSAF announcement and 2024 milestones respectively, providing the most specific public claims available about product specifications and investor relationships.

## Useful Claims

- CycloSAF has approximately 10 percent higher energy density than standard Jet-A aviation fuel.
- SpaceSAF is designed as a drop-in replacement for RP-1 rocket kerosene with over 4 percent higher energy density.
- Strategic investors include Frontier Airlines, Wizz Airlines, Volaris, Indigo Partners, and GenZero.
- ASTM certification for CycloSAF was in progress as of late 2024.
- The company was building its first full-scale US manufacturing facility, targeting 2025.
- A DoD partnership exists; specific terms are not publicly disclosed.
- Founded approximately 2020; headquartered in Salt Lake City, UT.

## Reliability Notes

The official website is the primary public source and is self-reported. Press releases (Business Wire, December 2024 and January 2025) corroborate the investor and product claims. ASTM certification status and manufacturing facility progress should be verified against current sources, as these were described as in-progress milestones. Airline strategic investor relationships are public and corroborated by multiple sources, reducing reliance on self-reporting for those claims.
