Replaceable battery containers save recharging time
A rapidly switched over battery container solution will enable inland waterway vessels to operate with zero emissions and no range anxiety.
The first order, comprising three units, was placed by ZES (Zero Emission Services) BV, a Netherlands based company founded in 2020 by ING Bank, energy and technical service provider Engie, the Port of Rotterdam, and Wärtsilä. The order was placed and two containers delivered in June 2021.
The Wärtsilä battery containers are installed on a 104 TEU inland waterway container vessel, which has been modified to allow two units to be mounted onboard. The system enables the vessel to operate on full electric power alone, with no carbon emissions being generated. The energy capacity is equivalent to that of approximately 36 electric passenger cars. When discharged, the containers can be exchanged and charged onshore using energy from renewable sources. This replaceability is unique since battery containers have thus far been stationary installations.
“Within the Dutch transport sector, inland navigation accounts for five percent of the CO2 emissions. By switching from diesel fuelled to electric propulsion, an important step can be taken towards realising the Paris Climate Agreement targets. Ships participating in the ZES service will eliminate around 1000 tonnes of CO2 and 7 tonnes of NOx per year,” says Willem Dedden, CEO of ZES.
The Wärtsilä swappable battery container is fully equipped with safety systems, including an onboard fire protection skid. It is connected for remote monitoring. The operational and certification trials were carried out commencing in the end of August 2021.
The concept, which is supported by the Dutch Ministry of Infrastructure and Water Management, is based on a network of open access charging points. Here, depleted battery containers can be exchanged for fully charged replacements. A ‘pay-per-use’ model has been set-up whereby ZES charges only for the cost of consumed renewable energy. This allows the vessel’s operating costs to remain competitive.
This first vessel fitted with the Wärtsilä battery containers, the Alphenaar commenced operations along the Zoeterwoude – Alpherium – Moerdijk corridor in the Netherlands on September 6 2021, transporting beer for Heineken.
