Abstract
Growing global temperatures and human population lead to a constant increase in energy demand (Smit et al., 2014). Even with the growing energy supply from renewable sources, consumption of fossil fuels is inevitable in the future (Khaleel et al., 2022). Therefore, we should focus on technologies tackling CO2 emissions and transitioning towards net-zero carbon emissions until 2050 (Feron, 2016). Post-combustion CO2 capture (PCC) using absorption has emerged as the most mature technology to capture the emitted CO2 (Smit, 2016). Monoethanolamine (MEA) has been considered for many years as the benchmark solvent for its effective absorption capacity and low material cost (Bui et al., 2018). An aqueous blend of 3 M 2-amino-2-methyl-1-propanol (AMP) and 1.5 M piperazine (PZ) was found to outperform MEA in terms of energy performance and degradation stability (Feron et al., 2020; Morlando et al., 2024). Therefore, it has been proposed as the new benchmark solvent for this technology (Feron et al., 2020).
