“…The study area consists of regions where we have conducted CCS research and specifically CO 2 -source-sinking mapping in the last two years. It consists of (1) the east coast of China between Shanghai and Hainan, (2) India, , (3) Sumatra, West Java, and Kalimantan of Indonesia, , Malaysia, Vietnam, (4) Thailand, , and Brunei (Figure ). The number of CPs included in the study is 520 (Table ).…”

“…For CO 2 storage readiness, the storage capacity should be large enough to store 100 years or longer of injection. We use the results of our previous studies − ,,− to determine the CO 2 storage capacity in three types of subsurface reservoirs: oil reservoirs, gas reservoirs and saline aquifers. In these studies, only major oil reservoirs with OOIP > 16 × 10 6 m 3 and gas reservoirs with OGIP > 20,000 × 10 6 m 3 are evaluated for CO 2 storage.…”

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.

“…Carbon capture and storage (CCS) has been recognized as a key technology for reducing CO 2 emissions from cement production since it can be used to mitigate CO 2 coming from both the calcination process and the combustion of fossil fuels providing the heat required for calcination [16]. Recently, Harsha and Lau (2023) published their study on using CCS to decarbonize Vietnam's power and industry sectors [17]. They have estimated the subsurface CO 2 storage capacity of oil and gas reservoirs as well as saline aquifers in Vietnam and conclude that there is adequate capacity to store anthropogenic CO 2 from both the power and industry sectors in Vietnam for over a century.…”

Vietnam is the world’s largest cement exporter. In 2022, it produced 118 Mtpa cement while emitting 109 Mtpa cement-related CO2, equal to 33% of Vietnam’s total CO2 emission. As Vietnam has pledged to achieve net zero by 2050, unabated cement-related CO2 emission must be drastically reduced in the future. This paper investigates the contribution of carbon capture and storage (CCS) to decarbonizing Vietnam’s cement industry to make cement production cleaner and more sustainable. A first-of-a-kind CO2 source-sink mapping exercise was conducted to map 68 cement plants to subsurface sinks, including oil and gas reservoirs and saline aquifers, using four CCS field development concepts. The results have identified four first-mover CCS projects where CO2 emissions from 27 cement plants are mapped to nearby offshore subsurface CO2 sinks. Two of these projects are located in Vietnam-north, one in Vietnam-central, and one in Vietnam-south. In the Vietnam-south CCS project, CO2 emission from the Kien Giang province is transported and stored in the offshore Block B gas field. In the other three CCS projects, CO2 emission is transported to nearshore saline aquifers in the Song Hong Basin. At a CO2 capture rate of 90%, these four projects will mitigate 50 Mtpa CO2, which is 46% of cement-related CO2 emission or 15% of total CO2 emission from Vietnam, thus making Vietnam’s cement production cleaner and more sustainable. Future research should focus on subsurface characterization of saline aquifers in the Song Hong Basin. The methodology developed in this study is usable in other cement-producing countries with significant CO2 sinks in the nearshore continental shelf.

“…Given the high amount of energy production and other human activities, it is highly likely that by 2050 this value will reach 1.5ºC [3]. Therefore, some short and midterm solutions should be applied to improve the current situation, for which carbon capture and storage (CCS) arises as one of the main possible solutions since it could reduce GHG emissions by almost 90% [2], [4].…”
