OXCCU ($26M to convert CO2 to jet fuel and PGA plastic for net-zero carbon emissions)

OXCCU, a UK cleantech startup founded in 2021, develops  highly efficient and inexpensive iron-based catalysts for direct conversion of recycled carbon dioxide and green hydrogen into jet fuels and plastics. OXCCU’s technology provides an attractive route not only to reduce carbon dioxide emissions, but also to produce carbon-neutral jet fuels and plastics.

Challenges: carbon neutral jet fuel

About 3% of global carbon dioxide emissions come from the aviation industry, and that number is going up. The industry has pledged to achieve net-zero emissions by 2050. Carbon-neutral jet fuels, which don't add to greenhouse gas emissions, are being looked into by the aviation industry. The carbon-neutral jet fuels include sustainable aviation fuels (SAF) and synthetic fuels.

Sustainable aviation fuel (SAF) is a type of fuel that has similar properties to conventional jet fuel but with a smaller carbon footprint. Compared to conventional jet fuel, it can reduce greenhouse gas emissions by up to 94%. SAF is made from green hydrogen and non-petroleum feedstocks, including forestry and agricultural waste, used cooking oil, and carbon captured from the air. SAF is a “drop-in” fuel, which means it can be blended with or replace traditional jet fuel without requiring infrastructure or equipment modifications.

Synthetic fuels are manufactured using green hydrogen and carbon dioxide or carbon monoxide. The process involves adding carbon to hydrogen to produce a liquid fuel, which can be gasoline, diesel, gas, or even kerosene. Carbon dioxide can be recycled from industrial processes or even captured from the air. Synthetic fuels are also a “drop-in” fuel.

OXCCU Technology

OXCCU has developed inexpensive, highly efficient iron-based catalysts for the direct and efficient conversion of recycled carbon dioxide (CO₂) and green hydrogen (H₂) to jet fuel range hydrocarbons. The iron-based catalysts are prepared using a facile, energy-saving, and cost-effective one-pot synthesis method. The size of the produced catalyst particles is around 14 nm. After activation, the catalysts show a high carbon dioxide hydrogenation activity and a high selectivity of jet fuel range hydrocarbons.
