Abstract: “Today the mix of the energy sector is changing from reduction of CO2 emission from fossil fueled power industry into a general focus on renewable industry which is emitting less greenhouse gases. Renewable fuels like biomass for electricity production or biogas for bio-methane production have a potential to create negative emissions using bio-energy carbon capture and storage (BECCS).

All sectors are still in the need for applying more sustainable carbon capture and storage (CCS) technologies which result in lower energy consumption while reducing the impact on the environment. Recently several promoters have been developed for solvent based technologies, but there is still a need to develop new approaches which can potentially reduce energy consumption even further.

Solvents typically used for CCS have the tendency to form carbamate. They are characterized by the speed at which they react with CO2. Advantageous kinetics results in smaller equipment size. But this is not the only benefit….”

Comments: the authors are using CapCO2, a stand-alone module developed at DTU in order to examine how MDEA solvent reactivated with carbon anhydrase works out. CapCO2 may be used as a CAPE-OPEN Unit Operation even if the authors are down playing this aspect by stating “it can take advantage of the CAPE-OPEN principles if the user finds a need for it”.
