Carbon capture & storage (CCS) is one of the most promising technologies for greenhouse gas (GHG) management. However, an unsolved issue of CCS is the development of appropriate long-term monitoring systems for leak detection of the stored CO2. To complement already existing monitoring infrastructure for CO2 storage areas, and to increase the granularity of gas concentration measurements, a qui...

Multi-stage compression is the normal method to achieve pipeline pressures of 100 bara for the transport of carbon dioxide (CO2) after capture in a carbon capture and storage (CCS) scheme. An alternative method is to partially compress the gas, liquefy it and then pump the liquid CO2 to the required pressure. The advantage of this process is that the CO2 stream can be further purified through l...

The cyclic carbonation-calcination of CaCO3 in fluidized bed reactors not only offers a possibility for CO2 capture but can at the same time be implemented thermochemical energy storage (TCES), feature which will play an important role future that has increasing share non-dispatchable variable electricity generation (e.g., from wind and solar power). This paper provides techno-economic assessme...

Energy and carbon neutral wastewater management is a major goal for environmental sustainability, but current progress has only reduced emission rather than using wastewater for active CO2 capture and utilization. We present here a new microbial electrolytic carbon capture (MECC) approach to potentially transform wastewater treatment to a carbon negative and energy positive process. Wastewater ...

Carbon Capture and Storage (CCS) or Utilization (CCU) are expected to be powerful tools to reduce CO2 emissions to the atmosphere from large scale sources, such as electric power, oil refinery, steal making, cement plants, with continuing their activities Those contain the CO2 separation or capture from flue gases at the plants and the transport and injecting CO2 into oil and gas reservoirs, an...

This study focuses on the derivation of a semi-analytical approach for the evaluation of surface uplift and caprock deflection induced by underground injection of CO2. The adopted methodology includes the development of amathematical model that incorporates the deformable behaviour of the storage reservoir and the flow of two immiscible fluids (CO2 and brine) within the aquifer while the surfac...

This report is in two sections: the first describes the flue gas and its treatment in post-combustion capture and the second covers the flue gas in oxyfuel combustion capture. The main components of the flue gas in pulverised coal combustion for postcombustion capture are CO2, N2, O2 and H2O, and air pollutants such as SOx, NOx, particulates, HCl, HF, mercury as well as other contaminants. The ...
