Global Marine Hybrid propulsion market growth and industry

Marine transport is the backbone of international trade. As per the data revealed by the International Chamber of Shipping based in United Kingdom, nearly 90% of the total volume of merchandise trade occurs via sea route owing to its low cost compared to other mode of transports such as rail and road.


Moreover, nearly 2 billion tons of crude oil, 1 billion tons of iron ore, 350 million tons of grains, and 11 billion tons of goods are transported by ship each year and about 90% of the world trade is carried by the shipping industry. Thus, the surge in international trade boosts the number of cargo vessels and ships fleet and which in turn, drives the market for marine hybrid propulsion.


Marine propulsion is the mechanism or system used to generate thrust to move a a naval vessel across water. At present, 90% of the sea-going naval ship are diesel-powered. Still, ship operators are giving a preference to cut their fuel bills and reduce the environmental eect of their naval operations.

Flapping Foil Propulsion System in Ship and Underwater Vehicles


There are numerous benefits to electric motor propulsion including that it’s quieter, more efficient at lower speeds and less smelly. It’s also expected to lower overall costs of ownership by reducing or eliminating the needs for oil and transmission fluid changes, filter and impeller replacements and starter problems. There’s less to winterize too. Additionally, unlike diesel or gas engines, electric motors provide full torque instantly so boats get up on plane faster. Aftermarket conversions (which currently make up the lion’s share of the market) can use existing drive shafts and components so there is a cost-savings when re-powering.


A hybrid marine propulsion system is any combination of a combustion engine and an electric motor. Electricity can be produced by one or a combination of the following: a combustion engine generator, a wind generator, a towed water generator or solar panels. A purely electric solution with solar panels is enviable due to its zero carbon footprint and low operating costs and various takes on theses systems have been gaining traction on alternative energy vessels. Advances in both energy storage and solar panel technology have reduced costs and physical footprint making solar power propulsion systems more feasible for use on boats.


Hybrid propulsion improves the fuel efficiency of vessels with variable power demand such as tug boats, fishing vessels, and others. The main propulsion types of marine hybrid propulsion are diesel-electric, parallel hybrid, serial hybrid, full electric, gas turbine, and fuel cell.A diesel-electric propulsion system can employ a single engine to drive several propellers or several engines to power one or more propellers.


Hybrid and pure electric propulsion systems have proliferated within the automotive industry, hybrid or electric boats are beginning to gain steam. Still, the marine world is a relatively small niche market that tends to follow rather than lead other industries in terms of innovation. Currently only less than 2 percent of boats today are integrating electric or hybrid propulsion. This slow adaption is partly due to the unique issues of boating. Boats have a different frequency and variance of use than cars and the market has many segments (ferries, sailboats, small high speed planers, large distance cruising yachts, etc.) where boats are used differently, making it hard to build one solution to fit all applications. However, a few companies are trying to change all that.


Power and auxiliary sailboats are typically propelled by inboard or outboard engines using diesel or gasoline fuel. A growing appeal has been placed on electric motors for these purposes – i.e. pure electric engines powered by large battery banks. As with any new technology, there’s an adoption curve. The early adopters are the technologists, visionaries and tinkerers and they make up only about 15% of the market. In marine, these are distance sailors that need efficient sustainability and autonomy but they’re also ferries and water taxis that operate on bodies of water where combustion engines aren’t allowed. Then come the trailerable towboats, tenders and fishing boats as well as charter boats to fill the boating sweet spot of the 25-75 foot midrange power market.


Because e-propulsion is in its infancy in the marine market, available solutions are few and they’re expensive. So far, most electric boats have been slow and small and had very restricted range but that is changing. There’s also the problem of infrastructure, which is the same for automotive: What is the range of these new vessels and where do they recharge? Just like a Tesla that you’d probably not take on a cross-country road trip, a boat may need charging stations close together to “fuel” quickly.


The marine hybrid propulsion is a combination of a battery-powered propulsion system along with alternate fuel such as diesel and liqueed natural gas (LNG) utilized during propulsion of the naval vessels. Marine hybrid propulsion systems are gradually emerging as one of the most preferred clean propulsion systems globally and are being used in several vessel categories. One of the major advantages of using hybrid propulsion systems is their clean and efficient mechanism, which significantly lowers emissions as compared to conventional propulsion systems. Features such as silent maneuvering, emission-free operations, and lower degrees of fuel consumption have prompted vessel and towage operators to invest in this technology.


The main applications of marine hybrid propulsion market are in offshore vessels and navy applications. Offshore patrol ships are good examples of ships that are equipped with the hybrid propulsion system. Patrol ships can be operated at low speeds by the electric motor and at a high power demand by the main engine. Moreover, Anchor Handling Tug Supply vessels are good examples of offshore ships with highly flexible power demand and per consequence, different operation modes, and sailing speeds.


The current trend in Navies is moving to electric hybrid gas turbine propulsion plants, again improving efficiency and reducing the need to refuel, while increasing operational availability and performance.  The electric propulsion ship by using electric motor is drawing considerable attention because of great advantages such as high efficiency, silent operation, controllability and low life-cycle cost. Especially interior permanent magnet (IPM) motor are considered motor attractive option for wide range operation ability and high torque density.


Hybrid propulsion Technology

A hybrid vehicle can achieve propulsion using a fuelled power source for e.g. a diesel engine or through a stored energy source, which is a battery bank and electric motor. Hybrid propulsion systems can be differentiated between configurations, where the diesel engines and the E-motors work in parallel on the propeller.


The electric propulsion system consists of a prime mover which may be of two types:  Diesel driven or Turbine or steam driven both generate mechanical energy and drive generators. The propeller shaft of the ship is connected to large motors, which can be D.C or A.C driven and are known as propulsion motors. Power for propulsion motor is supplied by the ship’s generator and prime mover assembly. Both the systems produce less pollution as compared to conventional marine propulsion system, which involves burning of heavy oil.


Marine hybrid propulsion systems are designed to use two independent drive systems for propulsion: a diesel engine and an electric motor, where electric power is generally stored in batteries or a super capacitor. The system utilizes the unused capacity of the main diesel engine to generate electricity and store it in batteries for later use.


Use of brushless permanent magnet electric motors and advances in lithium ion battery technology have allowed for leaps to be made in the rush to marine electric. Lithium-ion batteries are half as heavy as lead-acid batteries and last three times as long, and advances in their effectiveness and stability have been significant.


German electric motor manufacturer, Torqeedo, teamed with BMW and “marinized” the automaker’s i3 and i8 Series batteries for use in a variety of boats. They added a rugged damping frame to minimize shock, a venting system to channel gasses safely and waterproofing to IP67 standard. The new batteries tout a 31% increase in capacity (energy density) over the previous similarly sized model and their footprint (roughly 5’ x 3’ x 6”) can be fitted into even the most compact engine spaces.


Serial and Parallel Hybrid Boats

Currently, two approaches are battling it out on the water – serial and parallel hybrids. The serial hybrid system integrates a range-extending generator. The engine drives the generator, which powers an electric motor connected to the driveshaft—there is no mechanical connection between the engine and the driveshaft. A parallel system has a direct mechanical connection between the engine and the driveshaft but also drives an additional electric motor that operates as a generator – on the same shaft.


Range-extending power regeneration may be accomplished by a free-spinning propeller, which is easy to do on a moving sailboat and can be accomplished by using only one engine at a time on a powerboat. UK motor manufacturer, Hybrid Marine, is offering a third option: a multimode system that combines the best of serial and parallel approaches with an arrangement of clutches and gears.


Fully Electric Marine Propulsion Systems

Torqeedo’s Deep Blue 100i motor is the first fully integrated inboard electric propulsion system, which is available in two versions – 2400 rpm for faster planing boats and 900 rpm for heavier displacement vessels up to 120 feet. The focus of the entire system, from helm to prop, is on safety and it’s expanded the target market in terms of size, speed and typical use of the vessel.


A comprehensive propulsion system is a complex combination of voltages and that makes things complicated on the water. For example, one inboard motor installation may include all of the following:

400 VDC for propulsion using automotive battery technology
110/240 VAC for hotel loads on AC
24 VDC for onboard electrics
12 VDC to “wake up” the larger batteries and generator/range extender
bi-directional switching between 24 and 400V networks

That’s a lot of technology to pack into space-sensitive hulls. It also adds complexity and cost.



Gearboxes for hybrid propulsion systems

Manufacturers of transmission systems are developing new clutches and gearboxes to meet the requirements of ship operators choosing hybrid propulsion systems for their new vessels. All major engine manufacturers have developed diesel-electric engines and are introducing shaft generators into their propulsion packages. More vessels are being powered via a combination of batteries, electric motors and diesel engines, with combined power feeding thrusters. These can be passenger ships, tugs, workboats, offshore support vessels and increasingly, merchant ships.


Katsa has extended its range to accommodate hybrid propulsion applications, adding power-take-off (PTO) gearboxes and clutches and hybrid gearboxes, among other solutions. “We are providing innovative technical products in demanding applications with our new hybrid gearbox,” said Katsa director of gearbox business Tomi Dewes. The unit combines input from a diesel engine and electric motor to provide power to thrusters. Katsa’s newest product is a hybrid PTO gearbox, combining diesel and electric motors into a vessel´s propulsion driveline. It is flexible, with an adjustable optimal electric-motor ratio via clutches and control systems.


This hybrid PTO gearbox can cater for engine power up to 1,300 kW and has a hydraulic clutch dynamic torque up to 16,000 Nm. It has independent oil circulation with pump and integrated oil sump, hydraulic clutch control system with proportional valves and a clutch protection system with a remote bridge control. These PTO gearboxes also have flexible gear ratios for optimal engine and pump revolutions.The range will continue to expand, said Mr Dewes; a version that could provide 2.5 MW of power to thrusters is due to be tested and Katsa also plans to introduce a smaller version of the hybrid PTO in Q4 2020.


Other applications of the Katsa PTO gearboxes and clutches include hydraulic pumps on fishing vessels, tugboats and workboats. These PTO gearboxes can be used for driving and engaging cargo pumps on commercial vessels or mud pumps in oil and gas applications. Katsa is also developing new winch gears and winch electric powerpacks, incorporating permanent magnet (PM) motor technology. For the marine and offshore sector, these could be used for demanding applications such as escort winches on tugs. In the Netherlands, Katsa has worked with ADS van Stigt in developing these technologies, including clutched pump-drives, thruster PTO clutches and vessel drivetrain dropboxes.


Reintjes has also developed an electrically driven hybrid solution for gearboxes which enable vessels to sail at slow speeds, below the main engine idle speed. The electric drive is designed to achieve smooth running, with less noise and low energy consumption. For easy installation, the combined electric motor and generator are already flanged to the gearbox. The complete system is supplied with a frequency converter.


Reintjes gears have been supplied to several inland waterway tugs in the US this year. Reintjes WAF 665 reverse reduction gear systems have been installed on a series of towboats built at John Bludworth Shipyard. These are 25.6-m long vessels with Cummins QSK38 main engines that are compliant with Environmental Protection Agency (EPA) Tier 3 emissions requirements. The system turns four-blade Sound Propeller Services stainless steel propellers through WAF 665 gears with internal shaft brakes supplied by Karl Senner.


RENK has supplied power plant and gear systems to naval ships being built in Turkey, Spain and Pakistan. It is supplying power systems to four Ada-class, Milgem corvettes being built for defence forces in Turkey and in Karachi Shipyard, Pakistan. The first two of these ships are scheduled to enter service in 2023 and the other two in 2024.

The report exhibits 16.95 % growth in the containerized trade, 28.8% growth in the dry bulk carriers, and 2.3% growth in the container ships. Arise in the demand for maritime trade has further increased the demand for marine vessels. The hybrid propulsion is an essential system of the naval vessels. Therefore the increasing demand for container ships for maritime trades is boosting the market.


Increasing Operational Performance of Naval Vessels is Propelling Growth

Shipyard management and vessel owners are continuously investing in marine hybrid systems to improve the operational performance of naval vessels. The hybrid system is minimizing the power consumption of marine engines. The fuel-driven marine engines are able to handle a static load of around 65-80% of the overall capacity of a naval vessel. The reduction in the operational performance of the diesel-based marine engine is due to the interruption of wind and tidal sea waves. Moreover, introducing a battery-powered storage system act as a backup unit of the propulsion system. This battery-powered storage system is used to emulate the external load of the marine engines and help to reduce fuel consumption.

Ideal Power Signs $1.2 Million Contract to Partner with Diversified Technologies on Demonstration of B-TRAN™ Enabled High Efficiency Direct Current Circuit Breaker

Ideal Power Inc. (NASDAQ: IPWR) (the “Company”), pioneering the development and commercialization of highly efficient and broadly patented B-TRAN™ bi-directional power switches, was awarded a $1.2 million contract by Diversified Technologies, Inc. (DTI) to supply B-TRAN™ devices as part of a two-year, $3.0 million contract awarded to DTI by the United States Naval Sea Systems Command (NAVSEA). The objective of the project is to develop and demonstrate B-TRAN™ enabled high efficiency 12kV medium voltage direct current (MVDC) circuit breakers for the U.S. Navy as part of their ship electrification program. The project is funded under the Department of Defense’s Rapid Innovation Fund, which is designed to accelerate the commercialization of high-value, high-impact technologies.


Ideal Power’s B-TRAN™ technology is an enabling technology for high-efficiency MVDC circuit breakers. The Company believes that the low conduction loss of B-TRAN™ is an improvement of more than 50% compared to conventional semiconductor power switches, such as insulated gate bipolar transistors (IGBTs). In an MVDC circuit breaker, where the device is continuously conducting electricity and producing heat, the importance of the B-TRAN™’s low conduction loss is magnified and results in higher energy efficiency and simpler, lower cost and more compact thermal management. In addition, the fast switching speed of the B-TRAN™ can protect power distribution systems from faults 100 to 200 times faster than conventional mechanical circuit breakers. DTI intends to introduce a family of MVDC circuit breaker products incorporating B-TRAN™ as a result of the demonstration.


Ideal Power and DTI’s collaboration will help establish the viability of shipboard MVDC power distribution by delivering extremely fast fault interruption, low fault currents, flexible programmable coordination, and mechanical isolation, which are key factors to the reliable and safe operation of DC power systems. The U.S. Navy has stated a goal to electrify its fleet to increase shipboard power densities necessary to field more efficient ships with greater operational flexibility. The use of MVDCs in ship electrification and distributed DC networks would result in less vulnerable power distribution systems and naval vessels.


“Legacy circuit breakers have always been limited by their mechanical complexity, slow switching speed, and high conduction losses – all issues that are solved by the integration of our B-TRAN™ power semiconductor technology,” continued Mr. Brdar. “To date, the widespread adoption of DC distribution and transmission has been stalled by the lack of an efficient, low-loss, solid-state circuit breaker. B-TRAN™-enabled high-efficiency MVDC circuit breakers could potentially be utilized in various industrial applications, including medium-to-high voltage DC transmission systems and new electrical generation, such as solar and wind, that are DC-based. We believe B-TRAN to be a potential game-changer for distributed DC networks and will seek to leverage our collaboration with DTI for the U.S. Navy to establish inroads into the broader market for industrial and utility DC networks. According to a recent market research report from MarketsandMarkets™, the market for industrial and utility DC networks is anticipated to exceed $12 billion by 2024.”
