Corrosion in CO2 Post-Combustion Capture with Alkanolamines – A Review — CO2 capture and storage plays an important part in industrial strategies for the mitigation of greenhouse gas emissions. CO2 post-combustion capture with alkanolamines is well adapted for the treatment of large industrial point sources using combustion of fossil fuels for power generation, like coal or gas fired power plan...

A significant part of the cost for carbon capture and storage (CCS) is related to the compression of captured CO2 to its supercritical state, at 150 bar and typically 99% purity. These stringent conditions may however not always be necessary for specific cases of carbon capture and utilization (CCU). In this manuscript, we investigate how much the parasitic energy of an adsorbent-based carbon c...

Deep subsurface formations (for example, high-temperature oil reservoirs) are candidate sites for carbon capture and storage technology. However, very little is known about how the subsurface microbial community would respond to an increase in CO2 pressure resulting from carbon capture and storage. Here we construct microcosms mimicking reservoir conditions (55 °C, 5 MPa) using high-temperature...

We discuss our experimental progress toward energyefficient electrochemical CO2 capture from the atmosphere. First we discuss the latest results from an ongoing project that uses a modified-fuel-cell-based approach for CO2 concentration [1]. Using this approach, we have demonstrated CO2 capture from atmospheric concentrations with an energy consumption of less than 400 kJ/mol(CO2). We also disc...

One of the aims of the IEA Greenhouse Gas R&D Programme (IEA GHG) is to understand how to facilitate the introduction of technologies capable of making deep reductions in CO2 emissions, for example capture and geological storage of CO2. This technology faces a number of barriers to its introduction, such as the high cost of capture of CO2 from power plant. This high cost arises from the amount ...

In the Nuon/Vattenfall CO2 Catch-up project, a pre-combustion CO2 capture pilot plant was built and operated at the Buggenum IGCC power plant, the Netherlands. The pilot consist of sweet water-gas shift, physical CO2 absorption and CO2 compression. The technology performance was verified and validated models were obtained. This paper describes the validation of a WGS reactor model and the excel...

The selective capture of carbon dioxide in the presence of water is an outstanding challenge. Here, we show that the interior of IRMOF-74-III can be covalently functionalized with primary amine (IRMOF-74-III-CH2NH2) and used for the selective capture of CO2 in 65% relative humidity. This study encompasses the synthesis, structural characterization, gas adsorption, and CO2 capture properties of ...

Aerogels are a special class of porous material, which have excellent physicochemical properties such as low density, high porosity, high surface area and adjustable surface chemistry. Aerogels were first prepared several decades ago, but never truly commercialized due to their high cost. Technological advancements in the production and quality of different types of aerogel cut costs down and m...

Within the framework of the ETP project, the IEA has assessed the potential and the consequences of CO2 capture and sequestration for long-term energy policies. A number of policy scenarios were analysed quantitatively in order to assess the future role of CO2 capture technology from an economic, energy security and environmental perspective. The preliminary results suggest an important role fo...
