Transforming CO₂ into sustainable fuels for a cleaner, net-zero future.

Innovation for Tomorrow’s Energy Demand

About Us

IONIST is a carbon-recycling company pioneering eCOSAFTM, a next-generation CO₂-to-Fuel platform that turns industrial emissions into Sustainable Aviation Fuel (SAF).

We combine proprietary electrochemical CO₂ conversion, renewable hydrogen, and low-pressure Fischer-Tropsch synthesis to produce ASTM-compatible, drop-in jet fuel for today’s aircraft. Unlike conventional biofuels, our approach doesn’t compete for food or land. Installed on site at emission sources, eCOSAFTM recycles point-source CO₂ and closes the carbon loop.

Based in Newcastle upon Tyne, we build modular systems that scale from single facilities to multi-site deployments, enabling deep lifecycle CO₂ reductions when powered by clean electricity.

eCOGEN™

A membrane-free capillary electrolyser, running at low temperatures (40–60 °C), converts captured CO₂ into CO with renewable electricity. Compact, modular, and scalable, this unit delivers syngas for downstream fuel synthesis.

eCOSAF™

Our low-pressure Fischer–Tropsch reactor combines CO and renewable hydrogen to produce ASTM-grade SAF (C₈–C₁₆ hydrocarbons). The plug-and-play 20 ft ISO unit is designed for on-site deployment at SME and industrial facilities.

FT Reactor Module

IONIST’s low-pressure, modular Fischer–Tropsch reactor transforms syngas into ASTM-compliant C₈–C₁₆ sustainable aviation fuels, integrating effortlessly with the eCOGen electrolyser for maximum efficiency.

Data & Validation

Comprehensive pilot studies and third-party validations demonstrate reliable CO₂ conversion, robust syngas production, and high-quality fuel generation, confirming the technology’s readiness level (TRL 6+).

Key Advantages

Modular

Deployable at small, medium, and large scales.

Affordable

Low CAPEX , Early payback.

Efficient

Low-temperature, low-maintenance, membrane-free design.

High Impact
