The developments in automotive industry has always had a direct bearing on the marine industry. It is no different in the case of batteries. Due to continued focus on electric cars. Lithium Ion technology in particular has undergone major development.
There are definitely a lot of advantages in going electric- efficient powertrain, quiet operation and reduced carbon emissions. But batteries with higher energy density than of existing technologies especially for recreational boats which are used for relatively short runs still have lower price to benefit ratio.
In Lithium ion battery segment, Solar panels are now found on most cruising yachts and vary hugely in quality and price. The main limitations are in available space where they can be mounted without being in shade.
There has been significant development in 3D printed batteries in 2020 and there is a real possibility of developing cheaper, more energy dense and versatile batteries in coming years.
Energy density of 3D printed batteries is higher as the battery modules don’t need extra substances to glue and wire them together.
3D printing can greatly improve the cost efficiency as it will eliminate the need to manufacture the cells separately and then assemble them into module.
The growth of yacht battery market will closely depend on the growth in charging infrastructure. For example, in Netherlands, Skoon energy and Port of Amsterdam launched floating battery terminal powered by renewable energy to bring mobile energy storage into the port and inner city of Amsterdam.
The global Yacht Battery market is estimated at $XX Million in 2020, growing at –% CAGR till 2025.
The new MLI Ultra 1250 battery, the most compact in the Mastervolt lineup, offers five times more energy storage and 70 percent more space and weight savings than conventional lead acid batteries, according to Mastervolt, a division of Advanced Systems Group (ASG).
The newest model in Mastervolt’s Lithium-Ion Range may be found at exhibit #MB3508 at the Miami International Boat Show.
Due to the almost total lack of self-discharge and the limited accumulation of the “memory effect,” the MLI Ultra 1250 has a lifespan of 3500 cycles and a depth of discharge (DOD) of 80%. The MLI Ultra 1250 can be recharged in 60 minutes, much like the other models in the MLI Ultra line.
The MLI Ultra 1250, which is offered in 12 V and 24 V variants, is perfect for mobile and marine applications where space is at a premium. The battery cells’ high energy density was created as a drop-in replacement for size Group 31 and Group 49 batteries, which weigh only 15 kg.
Extra features of the product include: Self-balancing algorithm, Compatibility, All weather performance, Integrated battery switch and Plug-and-play communication.
The passenger ship Havila Castor used a Corvus Energy 6.1MWh Orca battery system to achieve zero-emission cruising in and out of Norway’s Geiranger fjord. The system is thought to be the world’s largest battery pack aboard a commercial ship.
When combined with other sustainable technology on board, energy storage systems have the potential to reduce CO2 emissions by about 30% and NOx emissions by 90%. CO2 emissions will be decreased by 50 percent or more as biogas is gradually blended in.
HAV Hydrogen has also prepared each ship for the installation of hydrogen and fuel cells, ensuring that it is future-proof. HAV Design, which designed the vessel, and Norwegian Greentech, which offered a low-energy, low-footprint ballast water cleaning system, were among the project’s many collaborators.
The hybrid gas-electric propulsion system, which included battery packs and generators as well as entire switchboards, was integrated and provided by Norwegian Electric Systems. Raven INS, a fully integrated bridge system with smart capabilities like data storage and analysis, was also added to help the organisation build better and more effective operations.
This is a significant achievement for Corvus Energy and a significant step forward in the decarbonization of shipping; a large passenger ship has sailed this journey silently and without emitting any emissions.
This demonstrates that technology is capable of allowing even huge ships to run in zero-emission mode for extended periods of time. The most beautiful coastline in the world now boasts the most environmentally friendly coastal ship in the world.
They have succeeded to create a new benchmark for the cruise and passenger sector by maintaining a constant focus on the environment and providing the greatest possible passenger experience. The initial trip on batteries alone went incredibly well, and they believe that by testing and finetuning all of the equipment on board, they can achieve much more.
There are more than 10 players in yacht battery market. Almost all battery manufacturers are actively researching on solid state battery and trying to figure out what the combination of solid electrolyte with different metals and oxides in the electrodes.
The energy density of a battery pack can greatly help in reducing range anxiety in electric boats. To achieve that, the lithium-sulphur batteries developed by Oxis Energy in the UK have a power density of 500-watt hours per kilogram or double of Tesla Model 3 batteries.
Taiwan based Xing Mobility has developed a Modular Battery System where the batteries are immersed in a non-conductive cooling fluid and can be assembled to power any kind of boats/yachts. Every unit is made up of 42 lithium ion cells, surrounded by the coolant
