PowerX and Imabari Shipbuilding will jointly develop the first prototype of the Power Transfer Vessel, "Power ARK," by the end of 2025.

The shift to zero emission boats and ships has been hampered by the enormous energy consumption and correspondingly low range of conventional electric boats. Flying on computer-guided underwater wings -- known as hydrofoils -- that reduce energy consumption by 80% compared to conventional planing craft, Candela's vessels soar above the waves in silence with 2-3 times longer endurance than the best conventional electric powerboats.

Class society RINA, together with technology providers ABB, Helbio (subsidiary of Metacon AB), the Liberian Registry, Wärtsilä and an Energy Major have entered in a common effort to deliver a solution with hydrogen as fuel that would exceed IMO 2050 targets for 70% reduction of carbon intensity without the need for extensive infrastructure investment, offering the shipping industry a low-carbon pathway in shorter timescales.

General Motors has acquired a 25 percent ownership stake in Pure Watercraft, a Seattle-based company that specializes in creating all-electric boating solutions.Through 2025, GM is investing $35 billion in electric and autonomous vehicle technology — including work to improve performance and reduce battery costs.

Ocean Infinity, the marine robotics company is pleased to announce it is a winner of The Clean Maritime Demonstration Competition, enabling the Company and its partners to build a Marine Propulsion Test facility, with an integrated Ammonia Marine Propulsion System. The test facility will demonstrate clean-fuelled technology eventually capable of powering Ocean Infinity's Armada fleet, using an innovative ammonia based fuel cell system.

Unitrove has unveiled the world's first liquid hydrogen bunkering facility for fuelling zero-emission ships. The unveiling, at the City of Glasgow College's Riverside Campus, is the culmination of months of work.

Stockholm-based Echandia has signed an agreement to supply the world's first emission-free high-speed catamaran with an integrated battery and hydrogen-based fuel cell system. The client is Green City Ferries AB and the ferry is planned for commercial traffic in Stockholm.

The cruise industry's first hybrid powered ship is set to debut summer 2023 as part of Royal Caribbean Group's ultra-luxury brand Silversea Cruises. The new class of ships, known as 'Project Evolution,' will operate using a trio of power sources including a fuel cell system, battery technology and dual fuel engines using liquefied natural gas as the main fuel. This hybrid solution, using fuel cell technology, allows the ship to be free of local emissions while at port.

Marking the start of the greenest London International Shipping Week yet, the UK backs a world-leading absolute zero target for international shipping emissions by 2050, as announced by Transport Secretary Grant Shapps. This target, which would need to be agreed through the International Maritime Organization, would be a significant increase of ambition for the sector, which is currently accountable for 3% of global emissions.
