This study estimated the induced effects of LNG, mega PV (photovoltaic), small PV, onshore wind and offshore wind power, which will be used as major power sources under the Korea’s energy transition policy. The 2015 Input–Output Statistics of Bank of Korea were used to reflect Korea’s economic structure. The MCI (manufacture, construction and installation) and O&M (operation and maintenance) of each power source would have different effects, so in the analysis the MCI and O&M of each power source were distinguished. According to estimation results, the induced-effect coefficients of the MCI are greater than those of the O&M in every power source. The induced production effect coefficient of the MCI is decreased in the order of mega PV > small PV > LNG power > offshore wind > onshore wind. The induced production effect coefficient of the O&M is decreased in the order of mega PV > small PV > onshore wind > offshore wind > LNG thermal. The induced employment coefficient of the MCI is decreased in the order of LNG thermal > mega PV > small PV > onshore wind > offshore wind. PV power and wind power have bigger induced effects and bring economic effects in Korean economy. The carbon neutrality and energy transition policies implemented by Korea have a certain level of induced effects and offset the burden of transition costs even if existing power sources are replaced with environmentally friendly power sources.
Carbon capture and storage (CCS) is considered as one of the important countermeasures to reduce carbon emission. The Korean government is providing complete support to commercialize CCS. In order to facilitate CCS projects in Korea, there are some preconditions that need to be fulfilled. The geologic condition of isolated sites to store CO 2 and technical condition of CO 2 capture, transport, and storage implementations must be technically feasible. Once all the/these geological and technical conditions have been met, another issue should be addressed. CCS projects require huge costs; it is, therefore, very critical to estimate the cost of the projects as preliminary data prior to the decision-making process. This study suggests the importance of cost analysis in conducting integrated CCS projects and (also) estimates the cost of CCS pipeline transport that will be implemented in the near future as a case study. The overall cost estimation structure is complied with Cooperative Research Centre for Greenhouse Gas Technologies Integrated Carbon Capture and Storage Economics Model with the data collected by the Korean companies (Korea Gas Corporation, Korea National Oil Corporation, and so on). The results show that the transport cost is $6.61 per ton CO 2 for 50 km both onshore and offshore, which incurred during the period of 20 years. The estimated cost is higher than that of the Australian projects, at least in the category of pipeline transport.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
