“…Due to increased demand on electrical energy combined with the necessity of the reduction of greenhouse gases emissions, new energy production methods need to be developed. Despite withdrawing from combustion of fossil fuels, combustion power plants still will have a considerable share in global energy production in the foreseeable future [1].…”

“…CLC (chemical looping combustion) is a new, promising technology for fuel combustion that allows to burn a wide range of fuels such as: gaseous (e.g., hydrogen, methane, syngas), liquid (hydrocarbons including heavy oils), and solid (coal, biomass) with significantly reduced emissions of pollutants as carbon dioxide or nitrogen oxides [1][2][3].…”

“…Assuming that the combustion process occurs only in the presence of oxygen, similar to combusting fuels in pure oxygen (Oxy-combustion), the final products from the fuel reactor will be both carbon dioxide and steam. Furthermore, after water condensation, carbon dioxide could be removed in the carbon capture and storage process (CCS) or even reuse in carbon capture and utilization process (CCU) [1]. In comparison to Oxy-combustion, the main advantage of CLC is that there is no need to use an expensive air separation unit (ASU) [5].…”

This paper contains the results of research on a promising combustion technology known as chemical looping combustion (CLC) and chemical looping with oxygen uncoupling (CLOU). The remarkable advantages of CLC are, among others, that concentrated CO2 stream can be obtained after water condensation without any energy penalty for its separation or significant decrease of NOx emissions. The objective of this work was to prepare a novel bi-metallic Fe–Mn supported on ZrO2 oxygen carriers. Performance of these carriers for the CLOU and CLC process with nitrogen/air and hard coal/air was evaluated. One-cycle CLC tests were conducted with supported Fe–Mn oxygen carriers in thermogravimetric analyzer utilizing hard coal as a fuel. The effects of the oxygen carrier chemical composition and process temperature on the reaction rates were determined. Our study proved that for CLOU, properties formation of bixbyite and spinel forms are responsible. Among iron ferrites, we concluded that iron-rich compounds such as Fe2MnO4 over FeMn2O4 spinel type oxides are more effective for CLOU applications.

“…What to do? A possible solution can be provided by chemical looping [7][8][9][10][11][12][13][14][15][16], a promising technology of low emission, with applications in electricity or heat production, as well as in chemicals and fuels. This novel technology is rapidly evolving towards an established "clean combustion" due to the intrinsic, very efficient CO2 separation.…”

Chemical looping can be considered a technology platform, which refers to one common basic concept that can be used for various applications. Compared with a traditional catalytic process, the chemical looping concept allows fuels’ conversion and products’ separation without extra processes. In addition, the chemical looping technology has another major advantage: combinability, which enables the integration of different reactions into one process, leading to intensification. This review collects various important state-of-the-art examples, such as integration of chemical looping and catalytic processes. Hereby, we demonstrate that chemical looping can in principle be implemented for any catalytic reaction or at least assist in existing processes, provided that the targeted functional group is transferrable by means of suitable carriers.

CC(U)S Initiatives: Public Effects and “Combined Value” Performance

2021

The changes in climate, which are associated with the emission of anthropogenic greenhouse gases, have been widely discussed by scientists and specialists during the last few decades. The promising way to reduce CO2 emission is to implement CC(U)S technologies (carbon capture, (utilization) and storage). However, CC(U)S initiatives are challenging that prevent their widespread adoption. The main purpose of the research is to prove that CC(U)S should be considered broader than a way to reduce emission, and such initiatives could lead to various public effects and create long-term “combined value” for the industry and wider society; all of these should be considered when making decisions on CC(U)S implementation. The results of the research are presented by highlighting bi-directional interaction between CC(U)S and society, including public acceptance and public effects; identifying the possible positive and negative impact of CC(U)S initiatives on the public; developing a system of indicators for assessing the public effects of CC(U)S; proposing the framework for a value at stake analysis (VAS) of CC(U)S initiatives in order to reveal and assess their “combined value”. The methodology of this study includes desk studies, decomposition technique, environment (E), health (H) and safety (S) (EHS) approach, classification techniques, and VAS analysis.
