Reducing CO2 emission and lowering the concentration of greenhouse gases in the atmosphere has quickly become one of the most urgent environmental issues. While a variety of technologies and methods have been developed, the separation of CO2 from gas streams is still a critical issue. Apart from establishing new techniques, the exploration of membrane materials with high separation performance ...

CO2 Storage in Saline Aquifers — Saline aquifers represent a promising way for CO2 sequestration. Storage capacities of saline aquifers are very important around the world. The Sleipner site in the North Sea is currently the single case world-wide of CO2 storage in a saline aquifer. A general review is given on the specific risks for CO2 storage in saline aquifer. The regional distribution of C...

To compensate for the high cost of CO2 capture, this study proposes a novel solution that integrates compressed energy storage (CCES) system into an oxy-coal combustion power plant with capture (Oxy_CCES). The integration has potential to create arbitrage from variations in electricity prices. proposed Oxy_CCES can achieve higher net efficiency 34.1%, and exergy 57.5%, than liquified oxygen sto...

in this study, bimodal meso-porous silica (uvm-7) synthesized and fabricated amino silane modified supports were characterized by powder x-ray diffraction (xrd), n2 adsorption/desorption, transmission electron microscope (tem), elemental analysis and titration. capacity of co2 capture on modified bimodal pore structure silica at 70°c was calculated using breakthrough curves; and it was found th...

Materials and processes for CO2 capture and utilisation are an essential part of a holistic approach toward a sustainable energy future. CO2 and energy are tightly intertwined as energy produced from fossil fuel combustion always generates CO2. A major environmental concern, CO2 could also become an invaluable resource for making carbon-based materials and chemicals, and a means to store energy...

Even as the acceptance of the fossil fuel greenhouse effect theory continues to grow amongst academics, statesmen and plebeians alike, the early adopters have already engaged in pre-emptive research activities aimed at mitigating the effects of such greenhouse gases. The focus of one such effort is on the capture and storage of CO2 (carbon dioxide) from anthropogenic fixed source emissions. Thi...

Reducing anthropogenic CO2 emissions to slow down the consequences of climate change concerns all developed countries. In the short term, one of the most viable options to cut down carbon emissions consists on CO2 capture and storage from large stationary sources such as power stations, cement plants, refineries, etc. The near-ready-to-use technology at this scale is amine scrubbing. However, i...

The U.S. Department of Energy (DOE) is the lead Federal agency for the development and deployment of carbon sequestration technologies. As part of its mission to facilitate technology transfer and develop guidelines from lessons learned, DOE is developing a series of best practice manuals (BPMs) for carbon capture and storage (CCS). The ―Site Screening, Site Selection, and Initial Characterizat...
