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...

CCS, Carbon Capture and Storage, is considered a promising technology to abate CO2 emissions from point sources. The present review deals with the principle of post-combustion capture techniques, including thermal or pressure swing principles, adsorption absorption, electrical membrane separation processes. Opportunities challenges are assessed. In first section absorption processes, several co...

A series of porous carbon materials obtained from biomass waste have been synthesized, with different morphologies and structural properties, and evaluated as potential adsorbents for CO2 capture in post-combustion conditions. These carbon materials present CO2 adsorption capacities, at 25°C and 101.3 kPa, comparable to those obtained by other complex carbon or inorganic materials. Furthermore,...

Flue gas from a plant using fossil fuels contains CO2. Thus power/process plants using fossil fuels contribute to climate change if CO2 in flue gas is not captured. The process of CO2 capture from flue gas is called „postcombustion‟ CO2 capture. Existing plants may be retrofitted with this process to minimize CO2 emission. Amine solutions are mostly used for this process to scrub the flue gas. ...

this study investigated different concepts for natural-gas-fired power plants with the co2capture, and compared them based on the net plant efficiency and emission of co2. the cycles were based ona six oxy-fuel, one post-combustion and two pre-combustion capture concept. this paper presented theresults of an environmental evaluation performed by the application of the life cycle analysis (lca) ...

It is widely recognized that fossil fuel power plants will continue to play an important role in the energy supply for a large number of countries in the decades to come. The implementation of suitable carbon capture and storage (CCS) technologies is an essential task to meet the objective of reducing green house gas emissions into the atmosphere and obtaining a sustainable power generation fro...
