Value Maritime and Carbon Collectors will together perform a conceptual design study for a new fleet of tugs to be built by Carbon Collectors. They will investigate the feasibility of capturing carbon on board these new MGO-fuelled tug boats, using VM’s technology.

Jointly, the two teams will investigate and determine:

  • the required installed power of the diesel generators;
  • the estimated CAPEX / OPEX;
  • the best discharge options for the captured CO2;
  • the optimal solution for unloading and underground storage.

‘This is a first for us,’ says Christiaan Nijst, director and co-founder of Value Maritime. ‘We’ve conducted many studies in relation to larger sea-going vessels but now Carbon Collectors are affording us the opportunity to apply our carbon capture expertise to tugs, extending the reach of our sustainable shipping solutions. We’re excited to see how these vessels will perform with our leading technology.’

Capturing all the tugs’ CO2 emissions

Once the design is proven, Carbon Collectors aim to use Value Maritime’s carbon capture module to the fullest extent. They are currently designing a custom fleet of power-efficient tugs with the construction of the first vessels scheduled to start in the first quarter of 2024. Once operational by 2026, their marine gas oil- (MGO-)fuelled tugs could be effectively capturing all of their CO2 emissions on board.

Both parties will not only review the carbon capture abilities of the vessels, but jointly look into the optimal solution for safely unloading and permanently storing the CO2 underground.

Haije Stigter, technical director at Carbon Collectors: ‘As a company aiming to speed up the reduction of CO2 emissions, we also want to make sure that our own fleet contributes by becoming carbon-neutral as fast as possible. For years to come, carbon-neutral fuels will not be available in amounts that are large enough to fulfill demands, so carbon capture and storage seems the only feasible option in the short and medium term.’


Value Maritime developed “Filtree”, a unique system that cleans both air and water from all ship types and includes an integrated carbon capture feature making today’s fleet (newbuild or retrofit) not only sustainable today, but future-proof.

The CO2 capture feature removes and stores carbon from the vessel’s exhaust gases and uses it to charge a CO2 battery, which can be offloaded and re-used to facilitate the growth of crops, used to enrich future fuels or it can be safely stored until needed – a clean circular solution.
