German shipbuilder Meyer Werft has introduced a concept for what it says would be the world’s first fully battery-electric cruise ship exceeding 80,000 gross tons, signaling a bold step forward in the industry’s push toward decarbonization.The concept, dubbed “Vision,” was unveiled at Seatrade Cruise Global in Miami. According to the yard, the 275-meter vessel would accommodate 1,856 passengers and deliver up to a 95% reduction in greenhouse gas emissions compared to conventional cruise ships.The design leans heavily on existing battery technology rather than speculative future solutions.

Australian scientists have demonstrated proof-of-concept for a quantum battery.Like conventional batteries, it charges, stores and discharges energy. However, unlike conventional batteries, it leverages unique properties of quantum mechanics such as superposition and entanglement rather than chemical reactions.The battery has a multi-layered organic microcavity and is wirelessly charged with a laser. It has been demonstrated to have rapid, scalable charging and energy storage at room temperature.The research by CSIRO…

In a major milestone for Auckland’s public transport network, the city’s first plug-in hybrid electric fast ferry has performed exceptionally on sea trials and will soon enter service on the busy Auckland to Devonport commuter route. The vessel achieved a top speed of 36 knots on all-electric mode, with the performance of the electric propulsion and onboard systems consistently meeting and surpassing expectations.Designed by Incat Crowther, built by Q-West Boat Builders with systems integration by Hamilton Jet…

Mia Elg, R&D Manager at Deltamarin, says there’s not many of the company’s new designs, no matter what the vessel type is, that don’t include batteries.Installing smaller battery capacity to a diesel engine driven vessel with electrical power train can enable spinning reserve. Here, an optimal number of engines can be kept online, and the batteries can work as a black out preventer. This can save, depending on the type of the ship and operation, anything between a few percent…
