“…In a carbon-constrained world, these young coal plants may need to retire early by midcentury, the likely time horizon when CBECCS can start to play a more important role. Specifically, we develop a scenario where a total of 150 GW of net-zero GHG emission CBECCS units (CBECCS-CrB2) are deployed, based on the scale of projected coal additions by the International Energy Agency (43). Specifically, we assume ∼24.3% of crop residues available in mainland China are utilized as input fuel, which can thus support the deployment and operation of 366 net-zero GHG emission CBECCS units (i.e., CBECCS-CrB2), each with a capacity of 410 MW (44).…”

“…In the broad context of designing China’s CCS strategy, besides gasification-based precombustion CO 2 capture technology as the focus of this study, postcombustion capture has also been viewed as a promising technology choice, especially as an option to retrofit existing coal-fired plants (43). Successful commercial-scale demonstrations have already been realized in China and elsewhere (22).…”

Realizing the goal of the Paris Agreement to limit global warming to 2 °C by the end of this century will most likely require deployment of carbon-negative technologies. It is particularly important that China, as the world’s top carbon emitter, avoids being locked into carbon-intensive, coal-fired power-generation technologies and undertakes a smooth transition from high- to negative-carbon electricity production. We focus here on deploying a combination of coal and biomass energy to produce electricity in China using an integrated gasification cycle system combined with carbon capture and storage (CBECCS). Such a system will also reduce air pollutant emissions, thus contributing to China’s near-term goal of improving air quality. We evaluate the bus-bar electricity-generation prices for CBECCS with mixing ratios of crop residues varying from 0 to 100%, as well as associated costs for carbon mitigation and cobenefits for air quality. We find that CBECCS systems employing a crop residue ratio of 35% could produce electricity with net-zero life-cycle emissions of greenhouse gases, with a levelized cost of electricity of no more than 9.2 US cents per kilowatt hour. A carbon price of approximately $52.0 per ton would make CBECCS cost-competitive with pulverized coal power plants. Therefore, our results provide critical insights for designing a CBECCS strategy in China to harness near-term air-quality cobenefits while laying the foundation for achieving negative carbon emissions in the long run.

BACKGROUND The Malaysia Green Technology Master Plan (GTMP) is a systematic framework and planning initiative to mitigate national CO2 footprints by targeting several sectors which include power generation (energy sector). Thus, the objective of this study is to analyze economic and environmental sustainability (via techno‐economic analysis) of CO2 mitigation technology (i.e. postcombustion CO2 capture system, PCC) that can be employed by the energy sector as a way forward for low‐carbon power generation. RESULTS The analysis was performed by using a previously developed hybrid mixed integer nonlinear programming and model predictive control (MINLP‐MPC) algorithm. Based on the simulation results, operation of coal‐fired power plant associated with PCC plant under fixed forecast conditions (year 2020) would be capable of delivering substantial net operating revenue, subject to carbon taxes at US$7, 10 and 14 t–1 CO2 (scenarios 1–3), with the highest revenue gained from Scenario 1 (US$7 t–1 CO2) of US$601 million yr–1. Contrariwise, PCC plant operated at minimum efficiency by only capturing c.24% from the total CO2 emissions (under three carbon tax prices), illustrating the ineffectiveness of this plant for promoting national environmental sustainability. CONCLUSION The big trade‐off between economic and environmental sustainability found in this study demonstrates the impracticality of PCC technology as a mitigation measure in pursuing low‐carbon power generation as part of Malaysia's GTMP. © 2018 Society of Chemical Industry
