CO2 mineralization not only captures and stores permanently but also yields value-added products utilized in, for example, the cement industry. has been shown to potentially substantially reduce greenhouse gas (GHG) emissions. Realizing mineralization's potential on a large scale requires a) solid feedstock, b) sources, c) low-carbon energy, d) markets products. In general, these four requireme...

Carbon Capture and Storage is being actively developed for deployment in fossil fuel power stations in an attempt to reduce future emissions of CO2 due to concerns about climate change. The deployment of this technology will cause an inevitable reduction in the overall efficiency of any electricity generation plant leading to an increase in demand for the fossil fuels used to power the generati...

In this paper, the development of a new potassium carbonateon alumina support sorbent prepared by impregnating K2CO3 with an industrial grade of Al2O3 support was investigated. The CO2 capture capacity was measured using real flue gas with 8% CO2 and 12% H2O in a fixed-bed reactor at a temperature of 65 °C using breakthrough curves. The developed sorbent showed an adsorption capacity of 66.2 mg...

Abstract Porous materials possessing high surface areas are of paramount importance in gas separation and storage, as they can potentially adsorb a large amount per unit mass or volume. Pore structure functionality also important factors affecting adsorbate–absorbent interactions. Hence, efforts have been devoted to developing adsorbents with accessible tunable functionalities realize improveme...

Carbon Capture and Storage (CCS) is a method to reduce anthropogenic greenhouse gas emissions thereby mitigating global warming. In CCS, carbon dioxide (CO2) is captured from fossil fuel-fired power plants or other large point-source emitters, purified, compressed and injected deep underground into subsurface formations at depths of or greater than 800m. At such depths CO2 is in a supercritical...

The IEA Energy Technology Perspectives (ETP) model has been used for an assessment of the future role of CO2 capture and storage (CCS) in a greenhouse gas emission constrained world. This bottom-up systems engineering model covers the whole global energy system “from cradle to grave”, and it contains a technology database. The market forces are simulated in a least-cost optimisation. Competing ...
