Replaceable battery containers have been installed on a 104-TEU inland waterway container vessel
Wärtsilä has developed and delivered a mobile battery container solution that will enable inland waterway vessels to operate with zero emissions.
The first order, comprising three units, was placed by Zero Emission Services (ZES) 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 were delivered in June 2021.
The battery containers are installed on a 104-TEU inland waterway container vessel, which has been modified to allow two units to be mounted on board. The system enables the vessel to operate on full electric power alone, with no carbon emissions 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 5% of 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 1,000 tonnes of CO2 and 7 tonnes of NOx per year,” said ZES chief executive Willem Dedden.
“Wärtsilä is committed to supporting all efforts towards the decarbonisation of shipping. This initiative is part of that commitment. We have leveraged our inhouse know-how in maritime battery and hybrid systems, our shore power and remote connection capabilities, as well as our extensive experience in serving inland waterway applications for the development of this product,” said Wärtsilä marine power director, electrical and power management systems Torsten Büssow.
The Wärtsilä swappable battery container is equipped with safety systems including an onboard fire protection skid and is connected for remote monitoring. The operational and certification trials were carried out at the end of August.
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.
The first vessel fitted with the Wärtsilä battery containers, Alphenaar, started operations along the Zoeterwoude–Alpherium–Moerdijk corridor in the Netherlands on 6 September 2021. The vessel transports beer for Heineken, the first customer for the service.
