Greek short-sea operator Neptune Lines has selected Netherlands-based Value Maritime to retrofit two pure car and truck carriers (PCTCs) with exhaust gas cleaning systems designed to accommodate future onboard carbon capture technology.
The systems will be installed aboard Neptune Tharros and Neptune Ethos during scheduled retrofit projects in summer 2026. Value Maritime said the agreement represents its first deployment in the car carrier segment.
The installations will feature Value Maritime’s 15MW Filtree system. While the technology is primarily designed to remove sulphur oxides (SOx) from exhaust gases, the configuration includes provisions for a future upgrade to the company’s onboard carbon capture system.
Space will be reserved on board for the installation of a carbon capture duct, allowing carbon capture equipment to be added at a later stage without requiring major modifications to the exhaust gas cleaning system.
The vessels each have a carrying capacity of approximately 4,700 vehicles and operate in the European short-sea market.
In addition to supporting compliance with sulphur emissions requirements in emission control areas, the Filtree system is designed to reduce particulate matter emissions.
The project forms part of broader industry efforts to assess the potential role of onboard carbon capture in reducing shipping emissions.
Commenting on the agreement, Value Maritime co-founder and director Maarten Lodewijks said: ‘Just like Neptune Lines, we are passionate about making a positive impact. Entering the PCTC market and installing our emission-reducing technology on board these vessels is an exciting step. […] Greece is a market we have been developing for some time, and we are proud to sign this agreement ahead of meeting industry partners at Posidonia in Athens this June.
George Kriezis, technical director of Neptune Lines, said: ‘ Neptune Lines is committed to continuously improving the environmental performance of our fleet. Our goal is the delivery of all cargo in the most cost and carbon-efficient way. Partnering with Value Maritime allows us to implement a practical and future-ready solution that reduces emissions while maintaining operational efficiency. This project marks an important step in our broader decarbonisation strategyrepla.’
