Increasing the carbon capture efficiency of the Ca/Cu looping process for power production with advanced process schemes
TL;DR: In this paper, the Ca-Cu process is proposed to be carried out in adiabatic, dynamically operated fixed bed reactors operating in parallel, and it is demonstrated that the formation of a high temperature plateau during the sorptionenhanced reforming stage of the process, caused by the decoupling between the steam methane reforming and the carbonation reactions in different positions along the bed, decreases the carbon capture efficiency that can be achieved in this process.

TL;DR: In this paper, a special report, prepared by Working Group III of the Intergovernmental Panel on Climate Change, provides information for policymakers, scientists and engineers in the field of climate change and reduction of CO2 emissions.
Abstract: This special report, prepared by Working Group III of the Intergovernmental Panel on Climate Change, provides information for policymakers, scientists and engineers in the field of climate change and reduction of CO2 emissions. It describes sources, capture, transport, and storage of CO2. It also discusses the costs, economic potential, and societal issues of the technology, including public perception and regulatory aspects. Storage options evaluated include geological storage, ocean storage, and mineral carbonation. Notably, the report places CO2 capture and storage in the context of other climate change mitigation options, such as fuel switch, energy efficiency, renewables and nuclear energy. This report shows that the potential of CO2 capture and storage is considerable, and the costs for mitigating climate change can be decreased compared to strategies where only other climate change mitigation options are considered. The importance of future capture and storage of CO2 for mitigating climate change will depend on a number of factors, including financial incentives provided for deployment, and whether the risks of storage can be successfully managed. The volume includes a summary for policymakers approved by governments represented in the IPCC, and a technical summary. The full special report (only in English) as well as the summary for policymakers (in Arabic, Chinese, English, French, Russian and Spanish) can be downloaded from the Web site: www.ipcc.ch/activity/srccs/index.htm.
