Summary
CleanJoule's public website at cleanjoule.com, describing its biomanufactured sustainable aviation fuel (CycloSAF) and a feedstock-flexible biochemical process it says yields higher energy density than petroleum-derived equivalents. This capture is the homepage only: product specifications, investor relationships, and dated milestones reported elsewhere are not established by this document. The GenZero investment in CleanJoule is separately documented.
Useful Claims
- CleanJoule's public website describes CycloSAF as a higher-energy-density sustainable aviation fuel alternative to Jet A, with ASTM International qualification in progress.
- This homepage capture does not state SpaceSAF rocket propellant specs, named airline/strategic investors, a DoD partnership, Salt Lake City headquarters, founding date, or manufacturing-timeline targets; those details were previously listed from other site pages and press releases and are unconfirmed here.
Verbatim
"CleanJoule delivers alternative, domestically-produced fuels, enabling the vital aviation industry to go farther, faster." — Home page, heading
"future flights will run on superior fuels including CleanJoule's CycloSAF, which delivers significantly greater energy density than Jet A, reduces engine maintenance, and can be domestically produced globally." — Home page, fuels section
"Accepted into ASTM International's Qualification Process" — Home page, fuel attributes list
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.
Capture gap. This homepage fetch is a short marketing shell. SpaceSAF, investor roster, DoD partnership, headquarters, founding date, and manufacturing-timeline claims recorded on the entity page and in press releases do not appear in this capture.
