Carbon Capture and Utilization (CCU) for Synthetic Fuels and Chemicals Production

Detailed overview of innovation with sample startups and prominent university research


What it is

Carbon capture and utilization (CCU) for synthetic fuels and chemicals is an innovative approach to decarbonizing the oil & gas sector while creating valuable products. This technology involves capturing carbon dioxide (CO2) emissions from various sources, including industrial processes and directly from the atmosphere, and converting them into synthetic fuels, chemicals, and other useful materials.

Impact on climate action

Carbon Capture and Utilization (CCU) for Synthetic Fuels and Chemicals accelerates decarbonization in the Oil & Gas Sector by converting captured CO2 into valuable products, reducing emissions. It enhances climate action by fostering sustainable energy transitions and mitigating environmental impacts, crucial for achieving global carbon reduction goals.

Underlying
Technology

CCU for synthetic fuels and chemicals encompasses a multi-stage process:

  • Carbon Capture: The first step is capturing CO2 from different sources. Common methods include:
    • Post-combustion capture: CO2 is removed from flue gases after combustion using solvents or membranes.
    • Pre-combustion capture: CO2 is separated from fuel before combustion, often through gasification processes.
    • Direct Air Capture (DAC): Emerging technologies are capturing CO2 directly from the atmosphere using specialized filters or sorbents.
  • CO2 Conversion: Once captured, CO2 is converted into valuable products through various chemical processes, often powered by renewable energy sources. This includes:
    • Electrochemical Conversion: Using electricity to drive chemical reactions that convert CO2 into fuels like methane or methanol, or chemicals such as formic acid or ethylene.
    • Thermochemical Conversion: Utilizing heat, often from concentrated solar power, to drive chemical reactions that transform CO2 into syngas or other valuable intermediates.
    • Biological Conversion: Employing microorganisms, such as algae or bacteria, to convert CO2 into biofuels, bioplastics, or other bio-based products.
  • Product Refinement and Utilization: The final stage involves refining the synthesized products to meet industry standards and utilizing them in various applications, including transportation fuels, chemical feedstocks, building materials, and consumer products.
