Electric and Hybrid Marine World Expo 2017

Electric boat technology strives to keep up with the auto industry.

Chevy’s Bolt EV just won Car of the Year at the Detroit Auto Show, and luxury auto maker Tesla reports sales figures for the Q4 of 2016 up an impressive 27 percent. What’s taking so long for the technology to trickle down to the electric boat category? “We are not converting the message as a group,” Phil Purcell, CEO and Executive Director of the Marine Industries Association of South Florida stated rather bluntly as the opening keynote speaker at this year’s Electric and Hybrid Marine World Expo in Tampa. “I drive a Tesla, own a Duffy Electric Boat, have a Torqeedo motor for my dinghy… Electric is not a fad, but the battery makers are all in competition for a small slice of pie, and they need to be working together.”
Torqeedo, in collaboration with BMW, is making the very latest automotive battery engineering available for boats. Adapted to work with Torqeedo’s 40- or 80-hp Deep Blue systems, the BMWi3 technology is based on prismatic cell design allowing for efficient cooling and even temperature distribution within the battery, all in a compact form and tucked neatly into an extremely rugged structure with external power and data connectors.
Prismatic cells require precision assembly in a robust frame to achieve a long service life. Early adopters of electric technology have discovered that charging and discharging over time leads to cell expansion and collapsing, hastening the aging process. Boat applications place high demands on shock resistance and the BMW/Torqeedo design addresses those concerns.
The battery is waterproof to IP67 standards and has laser-welded cell connections over a larger surface, suggesting a stronger and more powerful design than conventional spot-welded cell connections. Should a particular cell fail, interchangeable access points and modules allow for upgrades.
BMW’s battery management system detects a replacement module and adjusts for that cell accordingly, while still providing appropriate recharging levels for older modules.
Torqeedo debuted a 25kW Range Extender for the Deep Blue system that is the first inverter generator capable of supplying electricity for yachts and supporting serial hybrid systems. With a promise of reduced pollutants, less vibration and a longer life for the combustion engine, the system does not require a separate starter. Instead, it uses the electric motor included in the genset.
Sailboaters also seem enamored with Torqeedo’s Cruise Fixed Pod motor as an alternative to an inboard diesel engine. Winner of the 2016 DAME Design Award, this year’s upgrades include new electronic throttles, a dedicated high-resolution marine display and an easy-to-understand user interface. The pod can be charged from shore power, solar, a generator, and even hydro-generation while underway.
On the commercial side, BAE Systems introduced HybriDrive marine solutions that work in concert with leading marine diesel engines to provide efficient propulsion and auxiliary power systems. HybriGen Power & Propulsion eliminates conventional main engines and is targeted for passenger ferries, research vessels and expedition yachts. Hybrid Assist uses various components to drive a vessel electrically at low speeds and assist the main engine when high-end boost is required. Aimed at the tug market, BAE says there is a fuel cost savings and main engine hours savings of up to 50 percent. Their third product, HybriGen Zero, eliminates the need for conventional diesel generators with a focus on towboats and fishing fleets.
Several battery makers addressed thermal runaway—think Galaxy Note 7, hoverboards and Boeing Dreamliner battery fires—with proprietary heat dissipation design. AllCell Technologies, a Chicago lithium-ion assembler, offered a breakthrough honeycomb design that prevents the spread of thermal runaway. Scott Novack explained how their patented phase change composite, a mix of wax and graphite, keeps the battery in a constant cooling state and avoids “the domino effect prevalent in thermal runaway.”
While big names like Valence, Spear Power Systems and Rolls Royce were on hand touting their progress, there was also room for the garage entrepreneur. Seattle-based PureWatercraft debuted an all-electric engine resembling the outdrive of a stern-powered outdrive. “The difference is we built all the parts, including a more efficient propeller,” notes founder Andy Rebele. The Pure Outboard replaces a 9.9- to 40-hp engine, connects to standard steering cables and weighs under 100 lbs. With two modestly sized battery packs that charge from a standard 120V system, it delivers 35 minutes at wide open throttle or an entire day of typical tournament fishing on a lake. Rebele and his team of inventors are in the manufacturing stage with delivery expected this spring. “Quiet is what people pay for,” quips the former rowing coach.

Cruise ferry Viking Grace install turbosail for hybrid usage of wind power

Viking Grace

The cruise ferry Viking Grace, which was built in 2013 specifically for the route Stockholm (Sweden) – Turku (Finland), is the world’s first hybrid passenger vessel and will use wind energy along with the main power plant. The Finnish ferry operator Viking Line will be the first to introduce the technology on their cruise and ferry ships, said the shipping company. On board of the cruise ferry will be installed cylinder with height of 24.00 m and a width of 4.00 m. During sail, the cylinder rotates around its axis, creating phenomenon in which the air flow around the rotating body and creates additional power.

The new technology is called Rotor Sail Solution and developed by the Finnish company Norsepower, which is one of the leaders in the introduction of renewable energy sources in the marine industry. Into the ferry will be used turbosail, which is also called rotary sail, is the first such propulsion developed and patented a German engineer Anton Flettner in 1922. It spawned a class of rotary vessels using as a propulsion device characteristic. However, the introduction of large-scale development in maritime transport it came only at the turn of XX-XXI centuries.
The development of Norsepower is a modernized version of the Flettner rotor and quite compact. The operation of the propulsion unit is a physical phenomenon in which the air flow around the rotating body, creates an additional force. This effect allows the ship to move with much more momentum, as using the classic bulky sails. This phenomenon is called the Magnus effect, which will be used by cruise ferry Viking Grace and opens new age for maritime transport.
Preliminary studies promise a significant reduction in fuel consumption and therefore emissions. Viking Grace uses as fuel liquefied natural gas (LNG). Its consumption when using the installation Rotor Sail Solution will be reduced by 300 tons per year. Thus, the most environmentally friendly ship in the region will become even more green. The combination in one vessel engines to LNG, electric drive propellers, a special form of the body and the rotor sails – not found anywhere else in the world, makes Viking Grace one of the most environmental vessels in the world.
The technology has already proved its commercial viability of the operation on cargo ships. Preparing to implement the system on Viking Grace begun and will be completed in 2018 with the installation of turbosail. It is fully automatic and starts when the wind load is sufficient to be effective. If the system is not needed, it requires absolutely no additional cost.
“This is the first use of wind power for such a large cruise ship as the Viking Grace. As an engineering company based in Finland, we are proud to work with a large and well-known shipping concern. Together we go to a new era, where the use of an auxiliary wind power will be an important part of maritime transport”, said the CEO of Norsepower, Tuomas Riski.
The Rotor Sail Solution from Norsepower was named “Innovation of the Year” in 2016 at the exhibition Electric and Hybrid Marine World Expo in Amsterdam. Today it is one of the most promising developments in the field of renewable energy sources in maritime transport. Independent studies show that technology can save up to 20% of fuel per year, depending on weather conditions.

Marine Hybrid Propulsion Market- Positive Long-Term Growth Outlook 2022

The global market for marine hybrid propulsion is expected to possess a medium degree of competition till 2022. There exist a number of small-scale manufacturers that operate in key regional markets, along with players such as BAE Systems Plc., Caterpillar Inc., and Aspin Kemp & Associates that operate on a global front.
These key players are able to provide products and services across a large regional span and show a consolidated effort towards development of marine hybrid propulsion technologies.
According to a publication by Transparency Market Research, the threat of new entrants is expected to go down over time, owing to the presence of patented technology and the high level of brand loyalty that consumers show towards the prominent names in the market.

The global market for marine hybrid propulsion has been expanding at a CAGR of 8.02% in revenue from 2014 to 2022. This revenue is expected to reach US$2.77 bn by the end of 2016 and US$4.45 bn by the end of 2022.
Diesel-electric marine hybrid propulsion systems are expected to continue being the leading segment in terms of system configuration, albeit a small drop in market value from the past. By the end of 2022, US$2.24 bn in revenue is expected to be generated from the demand for marine hybrid propulsion systems.
Europe to Continue Leading Marine Hybrid Propulsion Demand
Europe and North America have respectively been the top consumers of marine hybrid propulsion systems in the recent past and are expected to remain at their top two positions till 2022.
Although Europe is expected to continue holding the leading positions, it may lose share to North America over the coming years. This does not imply a reduction in demand in Europe, but rather an increase in investments made by APAC and North America in marine hybrid propulsion. By the end of 2022, Europe is expected to take up 31.42% of the market value for marine hybrid propulsion systems.
Growing Need to Improve Fuel Efficiency Pushes Demand for Marine Hybrid Propulsion
“The cost of fuel is one of the larger chunks of any vessel operator’s bill. Add to that the volatility in fuel prices, operators are compelled to look for options that can help them reduce fuel consumption as much as possible,” states a TMR analyst. This implies the use of marine hybrid propulsion systems to make the best of the given power input.
The pressure on vessel operators to cut down their emissions is also very high in developed economies from North America and Europe. Regulatory norms are getting more and more stringent and emission norms in all fields have to be followed. The ECAs imposed by the IMO in 2015, for instance, reduced the maximum emission of sulfur from the previous 0.5% to 0.1%. Using marine hybrid propulsion technology is one of the best ways for most small and medium scale vessel operators to follow these norms.
Usage of Clean Fuels in Conventional Propulsion Systems to Pose High Threat to Marine Hybrid Propulsion
While advancements in the marine hybrid propulsion technologies are certainly paving the way for their increased implementation, similar advancements are being made in the adoption of clean fuels. Modern clean fuels are designed so that they can be used in conventional marine propulsion systems. This provides vessel operators an extremely cheap option over the installation of marine hybrid propulsion systems.
The threat of clean fuels in conventional propulsion systems on marine hybrid propulsion is expected to increase over time.
“There is still a large opportunity for marine hybrid propulsion companies through the new ECA declarations. ECAs are currently implemented in North American waters and are expected to be put into action across the Gulf of Mexico, the Sea of Japan, the Turkish Straits, and the Strait of Malacca over the coming years. The stringency of ECAs will most likely push vessel operators towards investing in marine hybrid propulsion systems,” adds the analyst.
The information presented in this review is based on a Transparency Market Research report, titled, “Marine Hybrid Propulsion Market – Global Industry Analysis, Size, Share, Growth, Trends, and Forecast 2014 – 2022.”
Key Takeaways:
Europe is expected to accrue US$1.40 bn in marine hybrid propulsion systems by 2022, leading their regional demand.
Diesel-electric marine hybrid propulsion systems expected to generate US$2.24 bn globally by 2022.
