Question

Which database is best suitable for the life cycle assessment of CO2 capture, Storage, and Utilization?

Answer 1

to quote the EU commission on LCA for carbon capture

"There is currently no standardised easily accessible LCI data on “CO2” and more specifically on CO2 capture technologies, thus there is no standardised data which would enable the upstream impacts to be calculated through a standard database such as Ecoinvent."

I think this means you need the mass and energy balance and need to make your own model. Be sure to check the charecterization factors to ensure they are mapped for the function you are trying to model.

Happy to be corrected if I am wrong, since I have been searching for one too.
