“…As mentioned earlier, chemisorption using amine-based solvents is a ready technology for retrofitting of current power plants. Based on that technology, pilot-scale power plants that have been implemented showed a CO 2 absorption capacity of 80 tonnes per day (Vega et al 2020). It is projected that the first integrated commercial carbon capture and storage along with coal-fired power plants will be open by 2020-2025.…”

“…Consequently, it will be utilised in the rest of the carbon-intensive commercial-scale processes afterward. Vega et al (2020) compared traditional and novel technologies that are used in carbon capture and storage areas such as post-combustion (traditional) and partial oxy-combustion (novel). At the pilot-scale of the absorption route, novel along with blend solvents have been deployed to reduce the energy footprint of the overall process before demonstration-scale trials.…”

“…There are desirable properties in novel solvents such as the high cyclic capacities, low production cost, low corrosiveness, lower degradation and thus lower by-products along with the environmental impact. Over the currently deployed pilot power plants, CO 2 capacity was in the range of 0.1 to 1 tonne per day at a low capacity level, while the high capacity level showed values in the range of 10-80 tonnes per day (Vega et al 2020).

“…Globally, there are 22 demo projects for carbon capture and storage based on power generation with the majority share of pre-and post-combustion projects, nearly equalling 10 and 9, respectively. There are only three demo projects based on oxyfuel combustion projects (Vega et al 2020). In terms of countries that invest in carbon capture and storage, the USA is leading the world with seven projects, and China comes second with five demo projects.…”

Human activities have led to a massive increase in $$\hbox {CO}_{2}$$ CO 2 emissions as a primary greenhouse gas that is contributing to climate change with higher than $$1\,^{\circ }\hbox {C}$$ 1 ∘ C global warming than that of the pre-industrial level. We evaluate the three major technologies that are utilised for carbon capture: pre-combustion, post-combustion and oxyfuel combustion. We review the advances in carbon capture, storage and utilisation. We compare carbon uptake technologies with techniques of carbon dioxide separation. Monoethanolamine is the most common carbon sorbent; yet it requires a high regeneration energy of 3.5 GJ per tonne of $$\hbox {CO}_{2}$$ CO 2 . Alternatively, recent advances in sorbent technology reveal novel solvents such as a modulated amine blend with lower regeneration energy of 2.17 GJ per tonne of $$\hbox {CO}_{2}$$ CO 2 . Graphene-type materials show $$\hbox {CO}_{2}$$ CO 2 adsorption capacity of 0.07 mol/g, which is 10 times higher than that of specific types of activated carbon, zeolites and metal–organic frameworks. $$\hbox {CO}_{2}$$ CO 2 geosequestration provides an efficient and long-term strategy for storing the captured $$\hbox {CO}_{2}$$ CO 2 in geological formations with a global storage capacity factor at a Gt-scale within operational timescales. Regarding the utilisation route, currently, the gross global utilisation of $$\hbox {CO}_{2}$$ CO 2 is lower than 200 million tonnes per year, which is roughly negligible compared with the extent of global anthropogenic $$\hbox {CO}_{2}$$ CO 2 emissions, which is higher than 32,000 million tonnes per year. Herein, we review different $$\hbox {CO}_{2}$$ CO 2 utilisation methods such as direct routes, i.e. beverage carbonation, food packaging and oil recovery, chemical industries and fuels. Moreover, we investigated additional $$\hbox {CO}_{2}$$ CO 2 utilisation for base-load power generation, seasonal energy storage, and district cooling and cryogenic direct air $$\hbox {CO}_{2}$$ CO 2 capture using geothermal energy. Through bibliometric mapping, we identified the research gap in the literature within this field which requires future investigations, for instance, designing new and stable ionic liquids, pore size and selectivity of metal–organic frameworks and enhancing the adsorption capacity of novel solvents. Moreover, areas such as techno-economic evaluation of novel solvents, process design and dynamic simulation require further effort as well as research and development before pilot- and commercial-scale trials.

“…In consequence, finding methods to convert CO2 to useful commodities could spur the development of novel techniques, products, and industries, and help to reduce the climate-altering emissions. Several international agreements have been reached, considering that carbon capture, utilization and sequestration (CCUS)-an integration of carbon capture and utilization (CCU) and carbon capture and storage (CCS)-is essential to cut CO₂ emissions in a sustainable way to limit the severity of climate change [6][7][8].…”
