HD Korea Shipbuilding and Offshore Engineering (HD KSOE), HD Hydrogen, and DNV recently signed a Joint Industry Project (JIP) agreement to develop and validate Pressure Swing Adsorption (PSA) technology for carbon capture in Solid Oxide Fuel Cells (SOFC).

SOFCs are high-efficiency fuel cells that generate electricity using natural gas, ammonia, or hydrogen as fuel. As part of this agreement, HD KSOE and its subsidiary HD Hydrogen will explore the integration of PSA-based carbon capture technology into SOFCs for shipboard power generation. The ultimate goal is to replace conventional ship propulsion and power generation engines with SOFC systems, significantly reducing maritime carbon emissions.o significant technical obstacles hindering its implementation.

PSA technology selectively captures and releases CO₂ by cyclically altering pressure within a capture chamber. This approach is expected to be at least 40% more energy-efficient than conventional CO₂ absorption technologies used in marine applications.
