In South Korea, researchers are delving into an innovative approach to enhance the eco-friendliness of carbon capture and utilization (CCU) technology. Rather than relying on fossil fuels, they are investigating the potential of using electricity to power this energy-intensive process. This shift, discussed at a symposium organized by the Korean Institute of Chemical Engineers at the Jeju International Convention Center, could not only boost CCU efficiency but also extend its applicability into the energy sector.
Traditionally, CCU, designed to mitigate carbon emissions, has paradoxically depended on fossil fuels for its production processes. By transitioning to renewable electricity, researchers believe CCU could evolve into a nearly zero-carbon solution. Hwang Dong-Won, head of the chemical process research division at the Korea Research Institute of Chemical Technology (KRICT), highlighted the imperative to adopt clean energy sources, emphasizing the role of electrification in this endeavor.
The benefits of electrification extend beyond mere fuel substitution. According to the experts, it can enhance efficiency by shortening reaction times and increasing product selectivity. Park Ji-Hoon, director of KRICT’s CO2 Energy Research Center, noted that overseas studies suggest electrification could drastically reduce reactor size and offer modular, decentralized deployment, facilitating implementation across diverse industrial settings with varying CO2 emission profiles.
Nevertheless, transitioning CCU to electrification presents substantial challenges, necessitating the development of new catalysts, reactors, and tailored processes. The researchers stressed the importance of a long-term perspective in developing electrified CCU, advocating for a gradual transition to renewable energy while leveraging existing CCU technologies.
Recognizing the significance of this endeavor, the South Korean government has endorsed a joint proposal from research institutes, focusing on zero-carbon, electrified CCU as part of a strategic global top-tier research program. Hwang emphasized the collaborative effort required for success, envisioning the development of cost-competitive technologies primed for widespread adoption as clean energy gains prominence.
