Marine battery manufacturer AYK Energy has expanded its presence in maritime electrification with the installation of its Aries+S battery system on what is set to become the world’s first battery-powered self-unloading bulk carrier.
The system has been developed in collaboration with Wärtsilä and will be delivered for CSL Australia (CSL) on the 11,000 DWT MV Yampu, currently under construction at Jiangjiang Nanyang Shipyard in China.
The vessel recently underwent its naming ceremony, with sea trials expected to begin shortly.
The Aries+S system provides 6,758 kWh of capacity and will operate as part of a hybrid diesel-electric configuration.
Around 50 per cent of the vessel’s energy demand will be met through shore power and battery energy storage, with the design allowing a pathway towards full electrification in future iterations.
Chris Kruger, Founder and President, AYK Energy, said: “Collaboration with Wärtsilä was central to this project’s success and we’d like to thank them and CSL for trusting AYK to provide the battery system. We are very proud to work on this groundbreaking bulk cargo vessel design and provide a battery with the highest standards of safety, quality and performance.”

The MV Yampu will be operated by CSL for Adbri Cement, supporting limestone logistics in South Australia. The self-loading, self-discharging design will replace the Accolade II and is expected to transport up to 2.7 million tonnes of limestone annually, representing a 35 per cent increase in carrying capacity.
The project builds on AYK Energy’s growing portfolio of large-scale maritime battery deployments across Europe and beyond.
These include hybrid ferry and specialist vessel applications, as well as a major contract with Wärtsilä to supply a 16 MWh battery system for Germany’s new ice-class polar research vessel Polarstern, due for delivery in 2028.
For the maritime sector, the MV Yampu installation reflects a broader shift towards hybridisation in bulk shipping, where battery systems are increasingly being integrated into propulsion and auxiliary power architectures.
It also signals a gradual move towards scalable electrification models, particularly for vessels operating on fixed routes with access to shore charging infrastructure.
