Corvus Energy is to supply its energy storage system (ESS) to Scandlines three new hybrid ferries, which will operate between Puttgarden on the German island of Fehmarn and Rødby, Denmark.
Following the success of the ESS on Princesses Benedikte – Scandline’s first hybrid vessel – Deutschland, Schleswig-Holstein and Prins Richard will each feature a 2.7MWh ESS, which consists of advanced lithium polymer batteries integrated with drive systems from Siemens.
Delivering significantly reduced carbon dioxide and other greenhouse gas emissions, the ESS optimises engine performance, decreasing maintenance and operating costs. Corvus’ integrated lithium polymer ESS is expected to last for more than ten years, while its adaptable modular structure allows vessel system integrators and designers to redesign systems to reduce system complexity and costs throughout the vessels.
Recently Scandlines, Corvus Energy and Lloyds Regster tested the system onboard one of the ferries by forcing the main diesel generators offline and measuring the ESS’ ability to provide full power for all of the ship’s systems in its absence. All test were completed successfully.
“The 2.7MWh of modules are the most reliable and safe battery in the world, designed to operate both house and drive line systems,” said Corvus Energy’s CEO Brent Perry. “Siemens, the integrator, is using this partnership opportunity as a template to develop a seamless, customer-based solution for current and future ferry fleets around the world.”
After the three newbuilds have launched, Scandlines will have the largest fleet of hybrid vessels in operation today. The ferries will provide a 24-hour service throughout the year, offering departures from both Germany and Denmark every 30 minutes.
“Scandlines is making a significant investment in new green technology that will benefit the people in the areas adjacent to the harbour and beyond in terms of reduced pollution,” said Fini Hansen, technical superintendent of fleet management at Scandlines Denmark. “Corvus batteries are used primarily to minimise diesel engines running at non-optimal load. Further, this means load-levelling function in order to keep a high level of fuel efficiency and reduced number of generating sets in service.”
