Independent Review of @syntholene Facility Confirms World Class Proof-of-Performance, Supports Potential for Cost-Competitive Synthetic Aviation Fuel. What our production data has demonstrated: World class efficiency demonstrating the structural cost advantage of our thermally-integrated process. Continuous, baseload operations, mitigating the need for battery and hydrogen storage. Capability to scale into a low cost producer across the low-carbon fuels market, and a credible potential to compete with fossil fuels, completely decoupled from crude oil.
