Problem
Long‑haul aviation relies on fossil jet fuel and lacks sufficient, affordable sources of Sustainable Aviation Fuel (SAF) to meet tightening emissions regulations and airline sustainability commitments. Existing SAF production pathways are limited in scale, often depend on feedstocks that compete with food or land use, and cannot be rapidly expanded to match projected fuel demand.
Solution
CirculAIRity addresses this gap by converting carbon dioxide captured directly from ambient air into synthetic SAF using a modular, scalable production system. The platform combines Direct Air Capture (DAC) technology with a catalytic fuel synthesis process to generate e‑fuel that meets aviation fuel specifications. By recycling CO₂ from jet exhaust back into new jet fuel, the system creates a closed‑carbon loop that does not increase net atmospheric CO₂ levels. The modular design allows facilities to be sized for a range of production volumes, enabling deployment at airports, industrial sites, or near demand centers. Integrated process control and automation keep operating costs competitive, supporting commercial adoption under existing regulatory frameworks.
Target Audience
Primary customers are commercial airlines and aviation fuel distributors seeking certified SAF to meet regulatory mandates and sustainability goals, as well as airport operators and industrial partners interested in on‑site fuel production.
