South Korea's HD Korea Shipbuilding & Offshore Engineering (HD KSOE) and its subsidiary HD Hydrogen have partnered with classification society DNV to work on CO2 capture technology for solid oxide fuel cells (SOFC). The project aims to develop and validate pressure swing adsorption (PSA) technology for capturing CO2 in SOFC, high-efficiency fuel cells that use natural gas, ammonia, or hydrogen as fuel. The innovative PSA technology selectively captures and releases CO2 by cyclically altering pressure within a capture chamber, offering a 40% improvement in energy efficiency compared to traditional methods used in marine applications. The agreement focuses on integrating PSA-based carbon capture technology into SOFC systems for shipboard power generation, with the goal of replacing conventional engines and reducing maritime carbon emissions. Vidar Dolonen, Regional Manager for DNV Korea & Japan, emphasized the importance of energy efficiency and carbon capture technologies in addressing the decarbonization challenge in the shipping industry. Seunghwan Oh, Vice President of Business Development and Strategy at HD Hydrogen, highlighted the significant role of PSA technology in Carbon Capture, Utilization, and Storage (CCUS) initiatives. The collaboration signifies a crucial advancement in exploring practical and scalable carbon reduction strategies for the maritime sector. Last year, HD KSOE made a substantial investment of around $80 million to acquire the majority of shares in Convion, a Finnish company specializing in SOFC and solid oxide electrolyzer cell (SOEC) technology. By integrating PSA technology with SOFC systems, the maritime industry can enhance power generation efficiency and accelerate the transition to carbon-neutral fuels.
