Carbon Capture & Storage on-board ships

Introduction to Carbon Capture & Storage

The shipping industry, a critical component of global trade, is a main contributor to global carbon emissions. In recent years, the maritime sector has faced mounting pressure to reduce its carbon footprint and operate more sustainably. One way it is accomplishing this is through the implementation of onboard Carbon Capture & Storage (CCS) systems. These innovative solutions capture carbon dioxide (CO2) emissions directly from ships, reducing their environmental impact and helping ship owners and operators meet the increasingly stringent international regulations.

Types of CCS

Carbon Capture & Storage technologies can be broadly classified into two main types:

✔️ Post-Combustion Capture: This technique captures CO2 after the fossil fuel (such as marine fuel oil or gas) has been combusted in air. The exhaust gases are captured and processed through chemical scrubbing or absorption methods to separate CO2. The CO2 can then be compressed and stored.

✔️ Pre-Combustion Capture: In this method, the fuel is partially oxidized or gasified to form a ‘synthesis gas’ (a mixture of hydrogen and carbon monoxide). The CO2 is then separated, captured, and stored, while the remaining hydrogen-rich gas is combusted.

In addition to these, there are other, more specialized capture technologies such as Oxy-Fuel Combustion and Chemical Looping Combustion, but these are currently less common in the maritime sector.

ERMA FIRST’s Carbon Capture & Storage Technologies

ERMA FIRST, a leader in green maritime technologies, offers two distinct onboard CCS systems:

✔️ CO2 Capture with Amine Absorption and Storage in Liquid State: This solution utilizes well-established amine absorption technology from land-based installations. A proprietary amine solvent absorbs CO2 from the flue gas in a dedicated absorber. The CO2-rich solvent is then directed to a stripper, where heat application regenerates the amine and releases CO2. The CO2 is then liquefied and stored under cryogenic conditions onboard the ship.

✔️ CO2 Capture with Calcium Hydroxide: This method offers a simpler alternative to amine absorption. It uses calcium hydroxide, a strong inorganic alkali agent, to absorb CO2. The flue gas comes into contact with the calcium hydroxide solution in a specially designed reactor. The resulting calcium carbonate slurry is dehydrated and stored onboard until its final disposal at authorized facilities.

Both ERMA FIRST systems effectively capture CO2, contributing to the reduction of greenhouse gas emissions and the transition towards a more sustainable maritime industry.




ERMA FIRST is leading the charge with its innovative portfolio of green technologies that centre on CO2 capture and storage onboard. Our cutting-edge solutions aim to not only meet but exceed IMO requirements, helping ship owners and operators navigate the course towards a sustainable and compliant future.
