SCHMID Energy System GmbH has been awarded a major contract by Dutch shipping company Portliner to design and construct a large-scale flow battery system with up to 1.5 MW of peak power. This state-of-the-art energy storage solution will serve as the primary power source for the zero-emission propulsion of an all-new container vessel.
This landmark project marks SCHMID Energy System’s entry into the maritime propulsion market and strengthens its position as a pioneer in sustainable energy storage solutions for shipping. The chosen flow battery technology offers high energy density, exceptional longevity, and flexible charging and discharging capabilities- all critical requirements for the reliable operation of large cargo vessels on long-haul routes. It allows charging the battery from onshore electrical charger or for very fast charging swapping of discharged electrolyte with charged electrolyte from charging pontoons will be developed.
“This contract is a major strategic milestone for our company,” said Henrik Buschmann, Vice President BU Energy Systems, SCHMID Group.
“We are leveraging decades of experience in innovative energy systems to enter the maritime sector for the first time, sending a strong signal for sustainable solutions worldwide. Partnering with Portliner allows us to combine technological excellence with a clear commitment to environmental and climate protection.”
Portliner is equally enthusiastic about the collaboration.
“With SCHMID Energy Systems, we have found a partner that not only brings deep technical expertise but also shares our vision for clean, future-proof shipping,” said Ton van Meegen, CEO, Portliner.
“The flow battery will enable us to operate our container ships entirely emission-free, making a tangible contribution to reducing CO₂ emissions in global trade.”
The vessel will operate without any fossil fuels, directly contributing to the decarbonization of maritime freight transport and supporting international climate goals.
Upon successful delivery of this project, SCHMID Energy Systems intends to further advance maritime applications of its flow battery technology – from cargo ships and ferries and swimming electrolyte pontoons.
