A recent study by the University of Michigan that looked at methods of carbon capture and utilisation (CCU) revealed which would be most beneficial for the climate and generate a ‘net climate benefit’.
A net climate benefit is defined by the study as the emissions avoided by using CCU technology that outweighs the emissions generated while capturing the gas and making the final product.
The research investigated the uses of captured CO2 in three categories – concrete, chemicals and minerals, ranking them by how much each category benefits the climate.
With estimates showing that captured CO2 could reduce climate-altering emissions by up to 15% by 2030, previous studies discovered that 6.2 gigatonnes of CO2 could be consumed annually by 2050 by using CCU to make products in the above categories.
