Dramatic efficiency increases fuel follow-on orders for world’s largest hybrid ferry fleet

The ferries will comprise the largest fleet of hybrid vessels in operation today.

Corvus Energy has again been selected as the Energy Storage System (ESS) of choice by Scandlines for their next three hybrid ferries. Based on the tremendous success of Scandline’s first hybrid, the MF Prinsesse Benedikte, the next three hybrids will again use a 2.7MWh ESS consisting of Corvus Energy AT6500 advanced lithium polymer batteries integrated with Siemens drive systems. The newly refit hybrid ferries will deliver significantly reduced greenhouse gas emissions, improved maintenance costs and optimized engine performance resulting in greatly decreased operating expenses.

The ferries M/V Deutschland, M/V Schleswig-Holstein and M/V Prins Richard, in operation on the Puttgarden and Rødby route (alongside MF Prinsesse Benedikte) will comprise the largest fleet of hybrid vessels in operation today. A vital economic link between Denmark and Germany, the ferries are in service 24 hours a day, 365 days a year and have sailings every 30 minutes from each side.

On a recent crossing with several senior Scandlines Executives, Denmark government officials, Lloyds Register engineers and Corvus Energy executive staff on board, the system was put to the test. With no notice, the diesel generators were purposely taken offline. Instantly sensing the loss of power from the generators, the Corvus Energy ESS seamlessly filled in the gap, and provided full power for all the ship’s systems without even a flicker in the lights. This was, in fact, a real life test of the system showcasing the capabilities of a Corvus Energy ESS as a truly meaningful part of the overall ship’s energy systems.

“The 2.7MWh of modules are the most reliable and safe battery in the world, designed to operate both house and driveline 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. We are honored to again provide energy storage for such a high profile and important fleet, with esteemed partners like Siemens and Scandlines.”

Corvus’ lithium polymer energy storage solution is a cost effective solution for hybrid ferries. It provides years of consistent and quality performance to meet the growing demand for more sophisticated, greener vessel systems. The integrated system will last for more than 10 years, optimizing ROI by multiples given the long life of ferry vessels.

“Siemens, with battery module supplier Corvus Energy, are proud to be a part of a unique team together with Scandlines. This is the world’s first system of this kind and we are very satisfied with the functionality and the reductions in CO2 emissions,” says Ketil Aagesen, Head of Sales Domestic Siemens AS.

Fini Hansen, Technical Superintendent, Fleet Management, Scandlines Danmark A/S agrees, “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. Corvus batteries are used primarily to minimize diesel engines running at non-optimal load. Further, this means load-leveling function in order to keep a high level of fuel efficiency and reduced number of generating sets in service.”

The adaptable modular Corvus ESS allows vessel system integrators and designers an alternative source of high energy that creates the opportunity to re‐design systems to reduce system complexity and costs throughout the vessel.
