Total CO2

CCU
is an industrial process that makes an economically valuable product using CO2 at concentrations above atmospheric levels. CO2 is either transformed using chemical reactions into materials, chemicals and fuels, or it is used directly in processes such as enhanced oil recovery.
CO2 Chemicals
using chemical reactions to build products, such as methanol, urea (to use as fertilizer) or polymers (for use as durable products in buildings or cars)
Possible link to use of chemicals in cars, buildings and agriculture
CO2 Fuels
Combining hydrogen with CO2 to produce hydrocarbon fuels, including methanol, synfuels, and syngas
-
Micro algae
processing the biomass to make products, such as fuels and high-value chemicals
-
-
-
Bioenergy with CCS
captures CO2 by growing trees, produces electricity through bioenergy and sequesters the resulting emissions.
-
-
Enhanced weatherings
Crushing rocks, such as basalt, and spreading them on land can result in the accelerated formation of stable carbonate from atmospheric CO2.
-
-
Soil Carbon Sequestration
Land management techniques for soil carbon sequestration to enhance agricultural yields
-
Biochar
“pyrolyzed” biomass: plant material that has been burnt at high temperatures under low oxygen levels.
-
Diffusion into Oceans
Possible link: Coal, oil and Gas
