Performance analysis of a double calcium looping‐integrated biomass‐fired power plant: Exploring a carbon reduction opportunity

Abstract

Summary Integrating biomass energy generation with carbon capture will result in “carbon neutral” to “carbon negative” technology. Countries like India and China possess significant reserves of limestone. Calcium looping (CaL) technology can prove to be a promising option for carbon capture in these countries. The present work aims at improving the performance of CaL‐integrated biomass‐fired power plant (BFPP) by exploring different looping configurations. In this study, (i) standalone BFPP, (ii) conventional CaL (single stage), and (iii) double CaL‐integrated BFPP have been systematically evaluated. A comparative performance evaluation of these three plants in terms of energy, exergy and ecological assessment, has been carried out. A detailed parametric study and unit‐wise exergy analysis of the best configuration among the three are presented to identify the scope for further improvement in efficiency and energy savings.

Energy and Exergy Analyses of Chemical Looping Combustion based 660 MWe Supercritical Coal Fired Power Plant

“…is assessed in terms of (kg/MWh), as given in equation ( 5 is the total amount of CO 2 emitted from combustion process (kg/s). Furthermore, the annual CO 2 emissions rate (for 7,000 working hours of the plant) per unit of coal is determined as given below (Pillai et al, 2019) from equation (7).…”

A novel calcium looping–integrated NGCC power plant configuration for carbon capture and utilization—Comprehensive performance analysis

“…At present, the most dominant and mature CO 2 capture technologies in the market are the oxy‐combustion and amine scrubbing 19,20 . However, these first‐generation technologies have the following major bottlenecks: solvent degradation, equipment corrosion, high energy penalty, and high operational cost 21 . Alternatively, the chemical and calcium looping technologies have become sustainable options to capture CO 2 from thermal power plant because of their salient features such as easy retrofitting, low cost, and energy penalty 22,23 .…”

“…Diego et al, also carried out a study to integrate the double calcium looping configuration with cement plants for CO 2 capture and reported 94% of CO 2 capture 30 . This double calcium looping configuration was later integrated with the biomass‐fired power plant 21 . The results demonstrated that the proposed configuration captures nearly 90% of CO 2 emissions with an extra energy and exergy efficiency penalty of only 0.1% when compared to the conventional biomass power plant.…”

Application of artificial intelligence to maximize methane production from waste paper

“…Energy from renewable sources is considered as the best alternatives to fossil fuels, 3,4 and there is a strong relation between the circular economy and renewable energy 5,6 . Biomass is a promising renewable energy source as it can be effectively used simultaneously for waste management and energy source 7‐9 . Waste paper and cardboard are two major fractions in the municipal solid waste (MSW) both by weight and volume 10 .…”
