OCCS (Onboard Carbon Capture System)
OCCS (Onboard Carbon Capture System)
IMO GHG(Greenhouse Gas) Emissions Strategy:
1) Reduce carbon intensity at least 40% by 2030, pursuing efforts towards 70% by 2050
2) Reduce total annual GHG emission 50% by 2050

Onboard Carbon Capture and Storage System (OCCS)
- HI AIR Korea’s OCCS captures and stores carbon dioxide emitted from the use of fossil fuels in ships.
- HI AIR Korea has acquired 7 patents jointly with DSME. The patent numbers are 1020200132181, 1020200139682, 1020200139692 and etc.
- HI AIR Korea provides a design that optimizes the carbon capture rate to satisfy the ship's operational data and requirements.
- FEATURES
- CO2 Capture using NaOH → CaCO3 Production using CaO
- Process Optimization through Various Chemical Reaction Tests
1) CO2 absorption by Caustic Soda water to Sodium carbonate
H2CO3 + 2NaOH → Na2CO3 + 2H2O
2) Extract Calcium carbonate by Calcium oxide from Sodium carbonate
Na2CO3 + CaO + H2O → 2NaOH + CaCO3(Solid)
- Compare advantages and disadvantages with competitors
<CO2 Absorption using Caustic soda>
<CO2 Adsorption using Amine Chemicals>
경쟁사와의 공정 및 장단점 비교 표 HI AIR KOREA Competitors * Process Method Absorption using caustic soda Adsorption using amine chemicals Installation Area Small
(One scrubbing tower required)Big
(Multiple towers required for quenching, Absorption and desorption)Electric Power
