Integrating compressed CO2 energy storage in an oxy-coal combustion power plant with CO2 capture

CO2 CAPTURE OPTIONS FOR AN EXISTING COAL FIRED POWER PLANT: O2/CO2 RECYCLE COMBUSTION vs. AMINE SCRUBBING

The existing fleet of modern pulverized coal fired power plants represents an opportunity to achieve significant greenhouse gas (GHG) emissions in the coming years providing efficient and economical CO2 capture technologies are available for retrofit. One option is to separate CO2 from the products of combustion using conventional approaches such as amine scrubbing. An emerging alternate, commo...

The Outlook for Power Plant CO2 Capture

There is growing international interest in carbon capture and sequestration (CCS) technology to reduce carbon dioxide emissions linked to global climate change. CCS is especially attractive for electric power plants burning coal and other fossil fuels, which are a major source of global CO2 emissions. This paper describes the performance and cost of CO2 capture technologies for large-scale elec...

Systems Analysis of Ionic Liquids for Post-combustion CO2 Capture at Coal-fired Power Plants

The main objective of this study is to investigate the feasibility and costs of ionic liquid (IL)-based CO2 capture systems at pulverized coal-fired (PC) power plants. The IL selected for this assessment is trihexyl(tetradecyl)phosphonium 2-cyanopyrrolide ([P66614][2-CNpyr]), achieving a 1:1 and reversible chemical reaction between [2-CNpyr] and CO2. A multi-stage equilibrium-based modeling fra...

Clean Hydrogen Energy and Electric Power Production with CO2 Capturing by Using Coal Gasification

Clean hydrogen is the major energy carrier for power production. The conversion of CO to CO2 and zero emission during hydrogen energy production causes high capital cost. It is a matter of prestige to optimize the process in order to make zero emission and cost effective production of clean hydrogen energy and electric power. In this era, coal gasification is th...
