Fuel the Future

OX•EFUEL™ is revolutionising the way we produce fuels, chemicals, and biodegradable plastics using CO₂.

Carbon-neutral fuel

OX•EFUEL™ is our Carbon-Neutral fuel made directly from sustainably sourced CO₂. A new world of fuels without fossil carbon and cleaner because of it.

Our one-step process Sustainable Aviation Fuel

OXCCU have developed and patented a simple one-step process to produce e-hydrocarbons. This highly selective and low CAPEX solution provides industry-leading Sustainable Aviation Fuel yields alongside other high value streams. Easily configured solutions to provide a product made to fit customer needs.

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.‍
