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.

Innovative Approach to Sustainable Fuel Production

OX1 Plant

The FOAK facility, based at London Oxford Airport and designed and operated by OXCCU, will produce 1 kg (~1.2 litres) of liquid fuel per day and will start operations in September 2024.

Scale-up journey

The plant is part of OXCCU’s strategic scale up journey as the first OXCCU plant out of the lab. It will provide the data key to the design, build and operations of the 160 kg (200 litres) per day OX2 plant, previously announced, which will operate at Saltend Chemical Park Hull in 2026. Commercial plants supplying the UK and elsewhere with PtL SAF will then follow.

The heart of the refinery of the future

Our mission is to enable future generations the continued use of hydrocarbon fuels but without their climate impact.

It is this approach which we believe will sit at the heart of the refinery of the future and allow future generations to use hydrocarbons indefinitely.

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.

Our novel catalyst

50% less CAPEX
Unique shape increases surface area, allowing more active sites for chemical reactions, leading to higher efficiencies
Enhanced Flow Dynamics
Optimise the flow of gases or liquids through the reactor, minimising pressure drops and maximising contact between reactants and catalysts
Increased Durability
The shapes improve mechanical strength, reducing catalyst degradation over time, prolonging operational life
Energy Efficiency
More efficient reactions reduce energy consumption, cutting operational costs and emissions during SAF production

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.

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.‍
