Transforming CO2 into Sustainable Aviation Fuel, Chemicals & Plastics

Discover how OXCCU combines CO2 with H2 and renewable electricity to create sustainable fuels and materials.

The future of sustainable fuel and petrochemical production

At OXCCU, we have developed cutting-edge technological processes and catalysts that revolutionise the way we produce fuels, chemicals, and biodegradable plastics. We combine CO2 from a variety of sustainable sources with H2 and renewable electricity, resulting in a sustainable and environmentally-friendly solution for a world without fossil fuels.

Converting Green Electricity to Green Molecules

Efficient Carbon Capture and Utilisation Process

Innovative Approach to Sustainable Fuel Production

In a net zero world, we will still need hydrocarbons.

Renewables can be used directly for power and ground transport, and some sectors can use hydrogen directly, but we will still need carbon-based molecules for sustainable aviation fuel (SAF), chemicals and plastics.

  • Fuels due to energy density
  • Petrochemicals and plastics as carbon is the backbone of the molecules.

But with no fossil fuels, where will we get them from?

Bio-derived fuels and chemicals based on ethanol or vegetable oil have well-known issues at scale due to limited feedstocks, land use, and competition with food.

Waste-based fuels and chemicals have huge challenges in aggregating enough consistent feedstock for decades, as well as technically in the many steps required to transform it.

The solution is utilising carbon dioxide (CO2).

This production pathway, known as Power-to-Liquid (PtL) or e-fuels,  is emerging as critical for the future of SAF, and regulation is already underway to support this transition. For example the EU requires 50% of the 2050 blending requirement under ReFuelEU to be via PtL.

The clear advantage versus the other options is scale; the feedstocks required, CO2 and hydrogen are theoretically unlimited given access to a lot of green energy. The challenge for e-fuels currently is cost.

Simplifying and scaling processes

OXCCU is focussed on reducing the cost of PtL by simplifying the process to convert the CO2 and hydrogen with high yield into SAF.

OXCCU is scaling up a novel catalyst and process to convert CO2 and hydrogen directly into SAF.

We are proving that it’s possible to make jet fuel-range hydrocarbons in a single step.

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.‍
