About 26% of global CO2 emissions came from coal-fired power plants (CP) in 2021. Furthermore, 72% of this came from Asian countries, especially China and India. Therefore, reducing CO2 emission from CPs is a must if Asian countries were to achieve net-zero CO2 emission by 2050 or soon afterward. In this study, we evaluate the potential contribution of carbon capture and storage (CCS) to decarbonize CPs in selected Asian countries. Our study area consists of the east coast of China, India, Sumatra, West Java and Kalimantan of Indonesia, Malaysia, Brunei, Vietnam, and Thailand which contains one-quarter of the global CP capacity. We screen all existing CPs in the study area for CCS retrofit readiness, considering the size and age of CPs, the CO2 transportation distance, and the storage capacity of nearby oil and gas reservoirs and saline aquifers. Analyses show that out of 520 CPs in the study area, 305 (59%) pass the screening criteria for CCS-retrofitting. If fully implemented at a 90% CO2 capture rate, CCS retrofitting will result in the abatement of 1.55 Gtpa of CO2, equal to 65% of CO2 emission from CPs in the study area and 16% of global CO2 emission from CPs. Furthermore, retrofitting CPs with CCS has the potential to reduce CO2 emissions by 18% for Malaysia, 26% for India, and 26% for Vietnam. However, the biggest CO2 abatement will be realized in India (715 Mtpa) and China (636 Mtpa). These results quantify the potential contribution of CCS in decarbonizing CPs in Asia. Policy implications to accelerate CCS implementation based on our findings are also discussed.

“…These authors have proposed establishing regional CCS corridors to facilitate implementation of CCS projects by using economies of scale [86]. Recently, the Indonesian government has been planning to install CCS in the depleted giant Arun gas field in North Sumatra [87,88]. recently estimated that there is 3.6 Gt of CO 2 storage capacity in saline aquifers in the West Taiwan basin, which can serve as storage sites for anthropogenic CO 2 emission from the west coast of Taiwan [59].…”

The objective of this paper is to propose a decarbonization roadmap for Taiwan to achieve net-zero emissions by 2050 by analyzing the status of fossil and non-fossil energies, screening applicable decarbonization technologies for their effectiveness, and then proposing an energy mix for the future. The novelty of this work lies in the screening process, which considers six, instead of one or two, categories: sustainability, security, affordability, reliability, technology readiness, and technology impact. Based on this screening, a decarbonization roadmap is proposed and compared with the announced net-zero emissions (NZE) plan. The proposed roadmap requires renewable electricity to grow at an average annual growth rate of 7% between now and 2050, instead of the 10.1% required by the NZE plan, which is more achievable based on issues identified with renewable energies during our screening exercise. The proposed roadmap improves on the NZE plan in the following aspects: (1) using clean coal technologies to decarbonize existing coal-fired power plants, (2) relying more on gas than wind and solar energies to replace coal and nuclear energy for power generation, (3) accelerating carbon capture and storage (CCS) implementation, (4) delaying the phaseout of nuclear energy until 2050, and (5) using blue instead of green hydrogen to decarbonize the transport and industry sectors. Implications of this roadmap for future research and development and energy policies are also discussed.

CO2 flooding is an effective technology for suppling condensate gas reservoir pressure and mitigating global warming. In this study, numerical simulation studies have been conducted to enhance gas recovery in Pen5 condensate gas reservoir using CO2 flooding. Pen5 reservoir has lasted 20 years of primary depletion, which affected by water invasion and retrograde condensation. In numerical simulation study, the GEM module is applied to implement history‐matching of production data, and good agreement has been achieved. Based on comprehensive geological understanding, production dynamics, and numerical simulation techniques, areas with minimal impact from water invasion and retrograde condensation contamination have been delineated. The comparison between continued depletion and the implementation of CO2 injection as a replacement technology in favorable areas has demonstrated the feasibility of CO2 flooding development in these regions. The analysis of the advantages and disadvantages of using miscible flooding and immiscible flooding was conducted, and the optimal development well pattern was evaluated. In the end, the plan of CO2 flooding of Pen5 reservoir has been designed and the gas production rate in the next 10 years has been predicted. The research findings of this study have reference significance for the practical application of CO2 flooding in developing condensate gas reservoirs.
