The engineering industry heavily relies on fossil fuels such as coal and petroleum to generate energy through combustion. However, this process emits carbon dioxide into the atmosphere, leading to global warming. To mitigate this issue, researchers have explored various methods to reduce carbon dioxide emissions, one of which is carbon dioxide underground storage technology. This innovative technology involves capturing carbon dioxide from industrial plants and injecting it into the saturated ground layer beneath the earth's surface, storing it securely underground. Despite its potential benefits, carbon dioxide underground storage efficiency needs improvement to optimize storage in a limited space. To address this challenge, our research team has focused on improving storage efficiency by utilizing surfactants. Furthermore, we evaluated how different carbon dioxide states, including gaseous, liquid, and supercritical, impact storage efficiency based on their respective pressures and temperatures within the underground reservoir. Our findings indicate that using surfactants and optimizing the injection rate can effectively enhance storage efficiency across all carbon dioxide states. This research will pave the way for more efficient carbon dioxide underground storage, contributing to mitigating the environmental impact of fossil fuels on the planet.

이산화탄소는 메탄, 오존, 산화질소, CFC등의 온실기체 중 약 50%를 차지하는 물질로서 이산화탄소 발생의 저감과 함께 회수 기술의 개발을 통한 배출량 억제는 환경적 측면에서 대단히 중요한 것으로 간주되고 있다. 따라서 각종 산업분야에서 발생하는 다양한 성분을 가진 다성분계 배가스내에 존재하는 10%내외의 이산화탄소만을 분리정제 농축하여 메탄, 메탄을 등의 다른 화학물질의 제조의 원료, 신에너지원, 고부가가치의 신제품 등으로 전환하는 연구가 활발히 진행 중이다.(중략)

화석연료의 배기가스로부터 온실가스를 저감할 수 있는 기술은 아민 등의 용매를 사용하여 물리 및 화학적으로 제거하거나, 막분리 등을 통하여 분리하는 기술이 이미 상용화단계에 도달하고 있지만, 이러한 기술들은 이산화탄소의 분리를 위하여 많은 에너지를 필요로 하고, 시스템의 효율을 크게 저하시키는 단점들이 있는 것으로 나타나고 있다[1]. 본 연구에서는 발전시스템으로부터 이산화탄소를 분리할 수 있는 여러 개념들에 대한 시스템설계기술의 개발을 목적으로 수행되었다[2,3]. 첫 단계로서, 기존의 개념들에 대하여 보다 단순화되어 질 수 있는 이산화탄소를 고형화시켜 배기가스로부터 분리시키는 공정을 도입하는 경우에 대한 발전시스템의 성능분석을 수행하였다.(중략)

As the sustaindble development becomes the main goal of the global world in the 21st century, it is important that technological innovations should be realized ecologically sound based on co-evolutionalry approach. From this perspective, the trans-disciplinary research method is gaining importance in the evaluation process of public funded R&D, especially in the environmental technology. In our evaluation research on the R&D projects of the $CO_2$reduction and sequestration technology in Korea, we attempt to apply a trans-disciplinary integrated method on the concept of the eco-innovation, the technology push and the market pull. Also, we try to develop the trans-disciplinary indicators of the environmental technology evaluation. This research confirms the necessity of trans-disciplinary research among the three academic perspectives, engineering, social sciences and public policy.

Reducing the emission of carbon dioxide, which is the main contributor to the green house effect, is becoming a global hot issue. Great attention has been thus given to utilization of carbon dioxide rather than just capturing and isolating it because it could convert carbon dioxide to high-value chemicals. In this paper, recent research trends are investigated on the catalytic conversion of carbon dioxide to syngas in the context of $CH_4$, dry-reforming, trireforming, and the electro-catalytic conversion of carbon dioxide through SOFC(Solid Oxide Fuel Cell) system. Research trends for utilizing syngas to high-value-added useful products, mainly fuel such as DME(Dimethyl Ether) are also discussed.

Considerable attention has been given to developing methodologies to reduce the emission of carbon dioxide from industry to meet strengthened environmental regulations. In this article, recent research trends on dry reforming of methane as an alternative method to reduce $CO_2$ emission from large scale industrial processes are addressed. To efficiently provide the energy needed in this strong endothermic reaction without additional $CO_2$ emission, it seems to be desirable to adopt autothermal reaction mode. The produced synthesis gas could be used as a reducing gas, or a feedstock for synthesis of chemicals and fuels.
