OXCCU is pronounced Ox.C.C.U.

OXCCU shareholders include Kiko Ventures (IP Group’s cleantech investment platform), Clean Energy Ventures, Aramco, Eni, United Airlines, Braavos Capital, University of Oxford, Trafigura, TechEnergy Ventures and Doral Energy-Tech Ventures, and key management. Series A funding was secured in 2023.

The key differentiator is being a one-step process, significantly reducing both CAPEX and OPEX when compared to conventional two-step processes. Our patented multifunctional iron catalyst converts CO₂ and H₂ directly into jet fuel range hydrocarbons using different active sites on the same catalyst surface, avoiding the step to first produce CO. It is underpinned by scientific breakthroughs published in top-tier scientific journals.This is distinctive amongst all other e-fuels companies who are focused on the two step approach. To our knowledge we are the only SAF company with a one step catalyst which does not produce significant amounts of alcohols as a byproduct. Other sustainable fuel companies typically rely on sources such as vegetable oil, used cooking oil or ethanol but they rely on crops and are limited due to land use. Others use waste plastics but significant challenges remain around waste sorting, feedstock reliability, controlling the gasification of the waste and the gas clean up. In contrast, by using CO₂, OXCCU can guarantee access to a consistent, reliable and scalable feedstock.‍

The OXCCU process eliminates the need for a Reverse Water Gas Shift or electrochemical syngas step to first produce CO, which leads to a step-change, simpler reactor design with higher efficiency and reduced balance of plant.Modelling completed by independent researchers from Imperial College London, through Imperial Consultants, has shown that OXCCU’s one-step process significantly reduces SAF cost due to higher selectivity yield in the jet fuel range and a 50% lower capital cost.

Production can be at a range of scale and in a range of locations. The key for sites is to be near a source of renewable energy and CO₂. The renewable energy is used to make the green hydrogen from water. The hydrogen then reacts with CO₂ to form SAF.

Hydrogen planes are very far away from being a realistic option. The advantage of SAF from power to Liquid (PtL) is there is no need for a new plane. The synthetically produced liquid hydrocarbons utilize the pre-existing fossil fuel infrastructure for transportation and distribution, encompassing pipelines and refuelling stations. The PtL SAF can be seamlessly combined with traditional kerosene, to ensure it complies with all existing jet A fuel standards. All geographical regions are expected to have SAF mandates eventually with e-fuels (PtL) sub mandates within them, with major aviation fuel purchaser regions (like the EU) having mandates already in place. Key to commercial plant locations will be access to inexpensive green electricity and therefore inexpensive green hydrogen as well as the availability of CO₂.

A significant amount of green electricity is used to produce the green hydrogen from water via electrolysis, but our process (CO₂ + H₂) to SAF is exothermic i.e. it releases energy and we operate under mild conditions.
