Beta Hybrid Propulsion

The Beta Marine, Hybrid-Marine partnership offers a range of integrated Hybrid systems developed to provide combined power and propulsion solutions for Narrowboats, Wide Beams & Dutch Barges. Hybrid systems are based on our renowned Greenline range of engines and available for the Beta 43 through to the Beta 115T.

Beta 50 Engine with Single Hybrid Motor/Generator

Single Hybrid Motor (Beta 43 – Beta 60)

For the Beta 43 up to the Beta 60, engines are fitted with a single motor/generator which provides 10kW of electric propulsion and when in generation mode 5kW of power capability. Which when added to the standard engine twin 60 Amp domestic battery alternators equates to a maximum of 8kW of available power whist under diesel propulsion.

Beta 105T Engine with Twin Hybrid Motor/Generator

Twin Hybrid Motor (Beta 75 – Beta 115T)

From the Beta 75 up to the Beta 115T, engines are fitted with a V twin motor/generator assembly which provides a total of 20kW of electric propulsion and when in generation mode a total of 10kW of power capability. Again factoring in the standard engine twin 100 Amp domestic battery alternators a maximum of up to 15kW of power can be available whilst under diesel propulsion, maximum generation power is set according to battery bank size.

Control Box & Control Panels

The electric motor/generator is also connected to a master control box managed by a push button controller complete with display panel.

Battery Bank

Our Hybrids can use many different battery technologies, this includes Lead/Acid, AGM & Lithium. For seagoing craft sealed batteries are required and AGM offers the most cost effective solution. For Lithium options please contact Hybrid Marine. Using powerful inverter technology, it is possible to run all the electrical domestic appliances you would expect at home and eliminate the need for gas (cooking) on board.

Electrical propulsion range will depend on the size of the available battery bank but a 40` sailing vessel requiring 4kW to achieve 5-6kts and utilising a 48v/200Ah battery bank (4x 12v/200Ah) would be able to travel for 2hrs at 5-6kts. Increasing the battery bank Ah size will allow a higher hull speed or greater range.

Solar Panels

Our solution additionally allows solar panels, wind generators and shore power integration. The addition of solar panels can make a significant contribution to your power needs, shown is 1kW array shown disguised as a hatch.

Use – Best Practice

The most efficient way to charge your battery bank is under diesel propulsion, which depending on engine model either the full 9 or 16kW is available at cruising speed 1,200 > 1,400 engine RPM. However should you decide to moor up in the countryside for an extended period and the batteries start to run low, depending on model the engine twin domestic alternators will provide either a 3kW or 5kW battery bank charging capability without the need to spin the prop.

In electric propulsion mode, the powerful single 10kW or twin 20kW motor/s provide ample power for non-tidal inland waterways and allows a silent & serene departure, voyage and arrival, no matter the time of the day. Additionally this mode produces no exhaust fumes which is especially pleasant when passing through extended canal tunnels or negotiating large flights of locks as well as being beneficial to the environment.

For every hour of diesel propulsion enough electrical energy is generated to power the electric motor for up to two hours of propulsion dependent on loads. By adopting this rule as best practice for diesel hybrid cycling, a significant improvement in fuel economy can be achieved together with an abundant storage of energy available for running domestic appliances.

Inland Waterway Keel Cooled Engines that are available with this option are the Beta 43 through to the Beta 115T please refer to our Greenline Engine Range. Hybrid is only available for engines specified with either a PRM150 or PRM500 gearbox option.
