EST-Floattech, a Dutch maritime battery supplier, has secured a contract with Electric Marine Support (EMS) to provide its Octopus Series battery system for Rhenus PartnerShip's fleet expansion. The project includes three new inland shipping vessels—Mannheim I+II, Wörth I+II, and Ludwigshafen. Mannheim I+II and Wörth I+II feature hybrid propulsion systems with High Energy batteries, while Mannheim I+II also integrates a hydrogen-electric propulsion system, achieving significant emission reductions. The vessels are being built at Den Breejen Shipyard in the Netherlands, known for constructing ships optimized for shallow waters. Additionally, Wörth will have a diesel-electric system convertible to fuel cells, and Ludwigshafen will be equipped with Octopus Series modules and a fuel cell for container transport. EST-Floattech focuses on lithium-ion battery systems for maritime applications, while EMS specializes in electric and hybrid propulsion. Rhenus PartnerShip, involved in sustainable logistics, aims to enhance its fleet with eco-friendly technologies.
