Modular Energy Containers - Zero Emission Shipping

The project

Zero Emission Shipping (ZES) supplies interchangeable modular energy containers (MECs), socalled ZESpacks, for new and existing inland vessels. 

The containers are charged using renewable power and can easily be exchanged at exchange and loading stations. These stations are standardized and equipped with an ‘open-access’ network. In the future, ZESpacks will also be able to work with hydrogen and fuel cells to propel the electric drivetrain that is required for ZES.

The project started with a large consortium and has led to the establishment of a company per April 2020, with the Port of Rotterdam as a shareholder. The world first commercial container vessel is sailing zero-emission as per September 2021 with Heineken as launching customer  

Scope and Dimensions

The ambition is to have 45 ships sailing as per 2027. Total investment is around €100 millions of which 50% subsidy will be required.



DAREL acted as business opportunity manager and JV representative on behalf of the Port of Rotterdam; DAREL facilitated the development of the business plan and build the business case model


When 45 ships are sailing in 2025, 500.000 tons of CO2 will be avoided (in addition to 3500 tons of NOx).
