Latsco Marine Management - A new study for OCCS

Latsco Marine Management, announced through social media (LinkedIn), their participation in the study “Onboard Carbon Capture Technologies”, commissioned by the European Maritime Safety Agency (EMSA).

Among several expert organizations, they supported the Hazard Identification (HAZID) workshops, contributing their operational expertise to the evaluation of onboard carbon capture applications within the maritime sector.

Furthermore, according to the study, (https://lnkd.in/eW5NKsmK) OCCS technologies rely on the integration of pre-treatment, absorption, regeneration, and temporary CO₂ storage systems, categorized into post-combustion, pre-combustion, and oxy-combustion.

The most mature and widely tested technology is chemical absorption, which allows for successively proven pilots and applications on ships.

The remaining technologies, such as membrane separation, cryogenic separation, and post-combustion, present further challenges in efficiency and energy consumption but show potential for development.

The environmental footprint of OCCS varies depending on the technology and the ship, with absorption systems yielding an average of 30-90%, and the use of biofuels further enhancing emission reductions by up to 120%.

The energy consumption of the technologies, particularly chemical absorption, ranges between 1.8 and 4 GJ/ton of CO2, with the energy load and the management of the solutions posing significant challenges.

Application on ships depends on many factors, such as space, structural strength, current infrastructure, and safety, and the choice of technology must consider the specific ship and trade.

Promotion through certifications from Classification Societies (DNV, ABS, Lloyd's, BV) and the development of international regulations (IMO, EU) are crucial for smooth integration and risk management, with gaps remaining in areas such as safety, documentation, and certification in routing and storage.

The integrated risk assessment (HAZID/HAZOP) highlights that CO₂ leakage, overpressure, combustion, and chemical leaks are key grey areas, requiring detection, containment, and mitigation systems.

The entire development and safety framework requires continuous collaboration between technology, regulation, infrastructure, and safety to ensure sustainability and compliance.

In conclusion, OCCS can significantly contribute to emission reduction, but their successful implementation depends on the mature development of technologies, the development of infrastructure, and the harmonization of regulations at the international level.
