Adding value to CO₂

Convert CO₂ to higher value products through OX•ESYN™ technology packages.

Made from Waste CO₂

OX•ESYN™ technology converts Hydrogen and waste CO₂ into highly reactive and useful Synthesis gas. This gas can be used as a feedstock for numerous current, proven technology pathways, diesel fuel, hydrocarbon wax and much more.

Efficiently turning hydrogen and waste CO₂ into synthesis gas for various applications.

OXCCU eliminates the requirement for fossil fuel feedstocks by offering a way to utilise green hydrogen and waste CO₂ as the initial step for current processing infrastructure.

Validated solution

Proven performance in pilot plant trials, collaborating with top international partners to scale up and bring the technology to market.

Energy Savings

Lower reactor temperatures and pressures in comparison to competing processes result in energy savings and reduced process emissions.

The advantages of the OX•ESYN™ technology


High activity catalyst enables smaller reactor sizes leading to less plot plan and smaller catalyst inventories

Energy Savings and Lower Emissions

Lower reactor temperatures and pressures compared to competitive processes leads to energy savings and lower process emissions

Longer Catalyst Lifetimes

Our iron based catalyst is more stable and robust towards catalyst poisons and deactivation leading to longer lifetimes

Higher Productivity

Highly selective catalyst with very high carbon efficiency achieving 100% selectivity to CO

Technology Validation

Performance proven in pilot plant trials. Working with leading international partners to scale up and commercialise technology

Experienced Engineering Team

A responsive and experienced engineering team is in place to support new projects and customers

Decarbonised production

Current processes using synthesis gas utilise either steam methane reforming or coal gasification technologies to provide the feedstock. OXCCU remove the need for fossil fuel feedstocks, instead providing a route to use green hydrogen and waste CO₂ as the starting point for existing processing infrastructure.

Unlock decarbonised products

The OXCCU process converts carbon dioxide and hydrogen into synthesis gas (syngas); a valuable feedstock for further downstream processes:


Ethylene glycol

Acetic acid

Oxo alcohols

Dimethyl ether


Polyglycolic acid (PGA)

Diesel fuel

Hydrocarbon wax

Who do you partner with to make sustainable aviation fuel?

For the AFF grant we have partnered with Coryton and Sheffield TERC (details in the release). Please also see our Series A investors.

Has the OXCCU process been tested? What scale?

Our novel catalyst has been validated for over 2000 hours in the lab. We are currently building a demonstration plant at Oxford Airport and already have plans for a larger demo plant. This fuel will be blended into jet A1 and then tested in a jet turbine engine APU.

Is this process energy-intensive? How much energy is consumed?

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.

What do airlines need to do to switch to hydrogen fuels? / Can existing planes be altered to accommodate hydrogen fuel or do new planes need to be developed/built?

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.

What sets OXCCU apart from others?

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.‍
