DNV has awarded Approval in Principle (AiP) to an amine absorption-based Onboard Carbon Capture (OCC) system developed by ERMA FIRST. 

The AiP was issued by DNV following the successful completion of a technical review, risk assessment and review of the company’s feasibility study for Onboard Carbon Capture (OCC) on RoRo vessels.

The ERMA FIRST CCS system uses amine absorption technology and a proprietary amine solvent to absorb CO₂ from flue gases. When heated, the chemical reaction that occurs reverses the absorption and separates the CO₂ from the solvent. The CO₂ that is released is subsequently liquified and stored under cryogenic conditions onboard while the regenerated solvent can be re-used, creating a highly efficient regenerative OCC process.
