Corvus Energy has received an order from Wärtsilä to supply four energy storage systems (ESS) to equip the offshore support vessel fleet operated by Louisiana-based Harvey Gulf.
The orders follow the successful sea trial of Harvey Energy, the first-ever LNG-battery hybrid retrofit of a platform supply vessel (PSV) in the Americas, and operated by Harvey Gulf. The company’s CEO, Shane Guidry, reported that clients and investors are increasingly demanding energy efficiency and emissions reduction: “This fleet of vessels will be crucial in assisting our clients’ efforts to achieve net carbon zero, and we will continue to listen to them and invest in technology that will assist with their goals.”
Wärtsilä will integrate the battery-based ESSs, each with a capacity of 745kWh, into its LNG-fueled hybrid-electric propulsion system.
After delivering hybrid ferry Gaarden in July 2020 and the fully electric ferry Düsternbrook, which will enter operations early this year, Holland Shipyards Group has signed a contract to build three additional hybrid vessels for Schlepp- und Fährgesellschaft Kiel (SFK).
The design of the three additional vessels will follow that of the Gaarden. The ferries will measure 32.40m by 8.80m and will be equipped with a hybrid drivetrain that can be powered by either generators or a battery-based energy storage system (ESS). The first two ferries will be delivered in February and May 2022 and the last in early 2026.
The Finnish Transport Infrastructure Agency has launched the Calypso, a new icebreaker concept boat equipped with a hybrid motorized removable bow. The vessel is currently moored in Mustola harbor in Lappeenranta (approx. 20km from the Finnish-Russian border) and has begun operating on Lake Saimaa and the deep waterways of the surrounding area.
The removable bow, which the vessel’s builder says is the largest of its kind, has been delivered by Turku Repair Yard as part of the Winter Navigation Motorways of the Sea II project. The €7.6m (US$9.25m) scheme, co-funded by the EU Connecting Europe Facility program, aims to develop and enhance Finland’s maritime winter navigation system and its safety during the winter.
The advisory board of solar power boat producer Silent-Yachts has been bolstered with the addition of Jochen Rudat, formerly central European director at Tesla.
“I see the same transition happening in the yachting industry as in the automotive industry,” commented Rudat following his appointment. “Since Silent-Yachts is clearly the leading pioneer of this change, I am eager to provide my support and advise on its further path. As the initiating catalyst for a more sustainable future in luxury yachting, we want to continue to drive innovation in the right direction. I see a lot of parallels between Tesla and Silent-Yachts, such as its commitment to creating a solar-powered catamaran from scratch by starting off with a white canvas and a bold vision.
US-based Pure Watercraft, a manufacturer of electric outboard motors, has acquired Elux Marine, a Minnesota-headquartered electric pontoon boat manufacturer.
Elux was founded in 2017 by Howard Root, a former medical device entrepreneur and lifetime Minnesota boater, and Bart Jones, a Minnesota boat craftsman.
“Our mission at Elux was to build a small, but focused electric boat manufacturer that would redefine the Minnesota pontoon experience,” said Root. “But as we introduced our Stealth and Breeze electric pontoons and saw the potential of electric boating, we knew we couldn’t stop there. We needed to scale. In meeting Pure Watercraft, we found a team that shared our passion to deliver boating that’s emission-free, maintenance-free and gas-free.
Founder and owner of NG3 Damien Feger discusses the demands and difficulties of electric power generation for marine vessels via shore power.
Is electric propulsion the answer to a sustainable industry?
In terms of emissions reduction, electric and hybrid technology is part of a portfolio of solutions, and this tech is becoming more and more mature. Ten years ago when we received our first PLUG (power generation during loading and unloading) order, it was just to cover hotel loads for the diesel-driven Color Magic and Fantasy vessels operating in Oslo, Norway. Back then, nobody was talking about electric or hybrid propulsion for marine vessels.
The firm continues to roll out its Clean Futures Plan with the launch of its third battery electric-hybrid island class vessel. Construction is well underway and sea trials are scheduled for February 2021. Following successful sea trials, the vessel will make its way to Point Hope Shipyards in Victoria in summer 2021 for final preparations. The ferry will begin service on the Campbell River – Quadra Island, Quathiaski Cove route in British Columbia in late 2021.
Solid-state battery technology is perpetually considered key to the next generation of electric and hybrid marine vessels. Leading developers explain the practicalities of this breakthrough tech, and look ahead to its future application.
Much like the EV industry, the marine sector’s efforts to decarbonize have depended on a series of technological milestones. Of the obstacles still to be overcome, the emergence and widespread application of solid-state battery technology has perhaps the greatest potential to mark a significant leap forward in electric and hybrid vessel capabilities.
“The primary challenge to broader application of electrification in the maritime industry has been the performance and safety limitations of more conventional lithium-ion storage technologies.
