Damen Shipyards has achieved official EU Stage V certification for its in-house-developed emissions reduction system (ERS). With many vessels operating in harbors and waterways close to or within urban areas, Damen’s teams opted to develop an emission-reduction system to address health issues related to the particulate matter emitted by diesel engines, as well as the environmental impacts resulting from excess nitrogen oxides.
Damen’s emission reduction system (ERS) combines soot filters with a selective catalytic reduction system to remove particulate matter and nitrogen oxides (NOx) as they leave the engine and before they enter the atmosphere, and also delivers noise reduction of an average of 45dB(A).
EMEC Hydrogen has chosen Genevos as a marine fuel cell supplier for the £2.2m (US$2.9m) HIMET (Hydrogen in an Integrated Maritime Energy Transition) project. The company will provide a zero-emission auxiliary power solution that will undergo trials on board a ro-ro ferry.
Based in Orkney, UK, and led by EMEC Hydrogen, the HIMET project will explore the decarbonization of ferries and shore-side activities in ports.
Over a period of seven months the project will design and demonstrate several solutions including hydrogen storage, the supply of onboard auxiliary power using a hydrogen fuel cell and the use of hydrogen in a conventional ferry propulsion engine.
A next-generation power and propulsion system has been launched by BAE Systems for application within the marine sector.
Called the HybriGen Power and Propulsion system, the flexible solution has been designed to help vessel operators achieve zero emissions while improving vessel range, electrical efficiency and propulsion power.
BAE’s modular accessory power system (MAPS) and modular power control system (MPCS) enable scalability, meaning the solution can be fitted to a range of vessels with differing power and propulsion requirements. The system has also been built using smaller and lighter components.
“Our investment in this next-generation technology will provide marine operators with cutting-edge capabilities to create clean transportation,” commented Steve Trichka, vice president and general manager of power and propulsion solutions, BAE Systems.
Finneco III, the third hybrid ro-ro vessel set for the Finnlines fleet, has been launched from the China Merchants Jinling Shipyard (Jiangsu) in China.
The new vessels have been designed to improve energy efficiency and reduce the environmental impact of the company’s fleet. They feature lithium-ion battery systems to enable zero-emissions port visits, and two low-emission two-stroke engines capable of outputting 12,780kW each. Furthermore, emission abatement systems, solar panels and an air lubrication system have all been installed to reduce the vessels’ emissions further.
The Finneco series vessels are 238m long and can achieve a speed of 20.7kts.
Electric & Hybrid Marine Expo USA & Canada Virtual ‘Live’, a free-to-attend, online conference that takes place on December 7, 8, 9, 2021, will provide a much-needed platform for US shipowners, shipyards, operators, fleet managers, naval architects and port authorities to engage with speakers and suppliers who will present the next generation of electric and hybrid marine propulsion and port infrastructure technologies and solutions.
Many vessels, from tugboats, ferries, offshore support vessels and other workboats, through to pleasure craft, luxury yachts, container ships and naval boats, are suitable for hybridization or full electrification.
Thoma-Sea Marine Constructors has awarded Siemens Energy with a contract to supply the power, propulsion, control systems and battery storage technology for two research vessels.
The new ships – called the Oceanographer and the Discoverer – will be acquired by the National Oceanic and Atmospheric Administration (NOAA).
Both ships will be equipped with SiSHIP Blue Drive PlusC advanced diesel-electric propulsion systems and BlueVault battery storage solutions. These technologies will enable the NOAA to optimize loading on variable-speed diesel engines, resulting in fuel savings and a reduction in maintenance and emissions.
Compared with vessels with traditional fixed-speed diesel engines of similar size and operating profile, the technology is estimated to deliver fuel savings of 15,000 gallons (68,191 liters) per year for each vessel – equating to a reduction of approximately 5,700 tons of CO2.
The Yara Birkeland, claimed to be the world’s first electric, self-propelled container ship, has undertaken its maiden voyage in the Oslo fjord in Norway.
“We are proud to be able to showcase the world’s first fully electric and self-propelled container ship. It will cut 1,000 tons of CO2 and replace 40,000 trips by diesel-powered trucks a year,” commented Svein Tore Holsether, Yara’s CEO.
The Yara Birkeland is a collaborative project involving several partners, including Kongsberg, which was responsible for the delivery and development of the technology on board the ship. Financial support was provided by Enova and the vessel was built by Vard.
The American Bureau of Shipping has released a white paper titled Emerging Battery Technologies in the Maritime Industry.
The white paper presents an overview of advantages, challenges and maritime applications for a range of battery types including metal-air, redox flow, ammonia, solid-state and lithium-ion batteries. It goes on to explore how emerging battery technologies can contribute to the decarbonization of the shipping industry.
ABS’s paper gives pros and cons for multiple different technologies that are relevant to the marine industry and analyzes their maturity compared with currently used lithium-ion batteries. Hybrid battery systems can also reduce vessel emissions but need sustainable and efficient battery technology to provide the necessary power.
