Carbon recycling applications: Practical applications of captured carbon in fuels, chemicals, and sustainable products.

Carbon recycling, often synonymous with CO2 Utilization (CCU), involves transforming captured CO2 into valuable products, thereby creating a circular carbon economy. The applications are diverse and growing, spanning chemical, material, biological, and fuel sectors. A major application is the conversion of CO2 into synthetic fuels, such as methanol, jet fuel, or other hydrocarbons, through chemical processes that combine CO2 with low-carbon hydrogen.

When powered by renewable energy, this creates 'e-fuels' that are essential for decarbonizing aviation and shipping. In the chemical industry, CO2 is recycled as a feedstock for producing important chemicals like urea (for fertilizers), polymers, and polycarbonates. Another high-impact application is the use of CO2 in building materials, where it is mineralized to form stable carbonates, effectively locking the carbon away permanently in concrete or aggregates. This process can enhance the material's performance while simultaneously reducing its carbon footprint. Biological recycling utilizes CO2 to accelerate the growth of algae or crops, which can then be used to produce biofuels, food, or specialty chemicals.

While carbon recycling applications offer tangible economic benefits and can substitute for products traditionally derived from fossil fuels, the overall volume of CO2 utilized is currently constrained by market size and the significant energy required for some conversion processes, meaning they will complement but not replace the need for permanent geological storage.

FAQs on Carbon recycling applications

Q: Which carbon recycling application is most valued for its potential to achieve permanent CO2 sequestration?
A: The use of CO2 in building materials for mineralization, where the CO2 chemically reacts to form stable, long-lasting carbonate minerals.

Q: What is the critical input, besides captured CO2, necessary for creating carbon-recycled synthetic fuels (e-fuels)?
A: The critical co-input is low-carbon hydrogen, and the overall process requires a substantial supply of renewable or non-fossil electricity.

Q: What is the main limitation on the total volume of CO2 that can be addressed through recycling applications?
A: The limitation is the size of the end-product markets; the total global demand for CO2-derived products is currently smaller than the vast quantities of CO2 that must be captured for climate mitigation.
