Reduce your CO₂ emissions with

Ship-Based Carbon Capture

Research & Development

Carbotreat maritime participates in numerous, important research projects to contribute to the development of green shipping. Innovation is an integral part of Carbotreat maritime. It helps us to unlock the potential of innovative maritime Carbon Capture Systems, which is essential to reduce the carbon footprint of the existing fleet and new ships.

Have a look at the research projects we are involved in:

Accelerate decarbonization

Our mission is to provide the shipping industry with Ship-Based Carbon Capture.

Why us?
With our field proven land-based solutions we have the right track record with developing emission reduction measures for ships to bring this technology to the seas. In doing so, we are taking an important step towards closing the carbon loop.


The EverLong project will demonstrate Ship-Based Carbon Capture on board two LNG-fuelled ships provided by TotalEnergies and Heerema Marine Contractors.

The system will capture CO2 on board TotalEnergies’ LNG carrier during a 3,000-hour test campaign. It will prove data on environmental emissions and the impact of motion on capture rates, capture solvent behaviour, and degradation. Subsequently, a second campaign of around 500 hours of CO2-capture operations on board Heerema’s Sleipnir ship will allow us to compare the system performance on both ships to provide further insights.


LNG-ZERO is an ambitious research project that’s running alongside the international carbon capture research project EverLonG. The goal: realizing an emission-free shipping industry.

The LNG-ZERO project includes the development of a complete cycle for the application of an advanced LNG-ZERO concept, which TNO originally introduced. To do this successfully, we combine the efforts of the energy and infrastructure developers (Shell, Carbon Collectors), end users (Heerema, Anthony Veder), and important suppliers and system integrators (VDL AEC Maritime with Carbotreat, Conoship International). TNO and the technical universities of Twente and Delft are the research partners working on the environmental topics. Safety and performance standards will be developed in conjunction with Lloyd’s Register.

DerisCO2 is a follow-up study based on the conclusions of the CO2ASTS feasibility study. TNO and Heerema also participate in this new study. The goal of the DerisCO2 project is to reduce direct CO2 emissions from ships and other seafaring units, by capturing the carbon dioxide and temporarily storing it on board.

The project is being implemented with a Topsector Energy subsidy from the Dutch Ministry of Economic Affairs (TCCU118008).

The feasibility study CO2ASTS focused on Ship-Based Carbon Capture and Storage for inland and short sea shipping using LNG ships. The objective was to gain insight into the main cost drivers, and analyse possibilities to minimise the costs per kg of CO2. This has been investigated and tested using three case studies. The dredger Ecodelta served as a case study within this research project.

The most important conclusion from the research is the good adaptability of an onboard carbon capture system through retrofitting due to the LNG as fuel and the space on board for the installation.

The study was supported by an EU INTERREG subsidy.
