1. CO2 chemicals: Reducing CO2 to its constituent components using catalysts and using chemical reactions to build products, such as methanol, urea or polymers.
2. CO2 fuels: Combining hydrogen with CO2 to produce hydrocarbon fuels, including methanol, synfuels, and syngas.
3. Microalgae: Using microalgae to fix CO2 at high efficiencies and then processing the biomass to make products, such as fuels and high-value chemicals, has been the focus of research efforts for many years.
4. Concrete building materials: CO2 can be used to “cure” cement, or in the manufacture of aggregates. Doing so stores some CO2 for the long term and could displace emissions-intensive conventional cement.
5. CO2-enhanced oil recovery: Injecting CO2 into oil wells can increase the production of oil. Normally, operators maximise oil and CO2 recovered from the well, but, critically, it is possible to operate EOR so that more CO2 is injected and stored than is produced on consumption of the final oil product.
6. Bioenergy with carbon capture and storage: In bioenergy with carbon capture, the operator captures CO2 by growing trees, produces electricity through bioenergy and sequesters the resulting emissions.
7. Enhanced weathering: Crushing rocks, such as basalt, and spreading them on land can result in the accelerated formation of stable carbonate from atmospheric CO2. It is likely that doing this on agricultural lands will result in enhanced yields.
8. Forestry: Timber from forests is an economically valuable product that could potentially store CO2 in buildings and, hence, displace cement use.
9. Soil carbon sequestration: Land management techniques for soil carbon sequestration can not only store CO2 in the soil but also enhance agricultural yields.
10.Biochar: Biochar application to agricultural soils has the potential to increase crop yields by 10% – but it is very hard to make a consistent product or predict soil reactions.
