Towards Sustainable Battery Recycling: Selective Desorption of Nickel(II) and Cobalt(II) from Amino‐Polycarboxylate Derivate Ligands in Model Systems Open
Inter alia due to the high demand for lithium‐ion batteries, the required critical heavy metals have become a scarce resource. Consequently, effective recycling processes that enable the recovery of such materials are of high interest. A s…

Direct Air capture (DAC) deployment: A review of the industrial deployment Open
Currently, scientists and investors consider Direct Air Capture (DAC) as one of the candidates to reduce CO2 emissions. The emissions cut is pressing since 30% (i.e., 20 GtCO2/y) of the current greenhouse gas emissions must be addressed by…

Direct air capture (DAC) deployment: National context cannot be neglected. A case study applied to Norway Open
DAC deployment is still an open question. Recent publications focused on energy consumption and the relationship between the cost of captured CO2 and operating conditions. These works addressed a preliminary assessment of the best location…

Aerosol growth in CO2 absorption with MEA, modelling and comparison with experimental results Open
A new and improved aerosol model has been developed and tested against experimental data. An e-NRTL equilibrium model for MEA was extended to cover sulphuric acid containing droplets and validated against new eboulliometer data in this wor…

Phase Equilibrium Measurements of Ammonia Based CO2 Capture Solvents with FTIRr for Gas Phase Analysis Open
Vapor-liquid-solid equilibrium (VLSE) was measured for four solvents (blends A-D) at atmospheric pressure in a low-temperature setup at 20 oC and at 20, 35, and 55 oC for blend E. The blends are ammonia-based aqueous solutions selected to …

Profiting from CCS innovations: A study to measure potential value creation from CCS research and development Open
Globally, large private and public funds are invested into CO2 capture and storage (CCS) research to provide the knowledge and technology required to mitigate CO2 emissions below a sustainable level. A pertinent question to ask is whether …
