Project Description

Beta Hybrid Propulsion

The Beta Marine, Hybrid-Marine partnership has delivered a state of the art, robust and reliable hybrid solution 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 43 Engine with Single Hybrid Motor/Generator

Beta 90 Engine with Twin 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 100 Amp domestic battery alternators equates to a total of 8kW of available power whist under diesel propulsion.

Twin Hybrid Motor (Beta 75 – Beta 115T)

From the Beta 75 up to the Beta 115T, engines are fitted with a twin motor/generator 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 total of 13kW of power would be available whilst under diesel propulsion.

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

All our Hybrids utilise a 48V battery bank that is essentially a vessels domestic power supply. 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.

Depending on whether you opt for 400Ah or 800Ah battery bank up to 30kWh of energy can be stored, this would provide 8 to 12 hours of electric propulsion for a Narrowboat or 4 to 6 hours for a Wide beam or Dutch Barge. Or if this energy is retained for domestic use there will be an abundance of power available during sensitive hours with no need to run the engine.

Solar Panels

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 8 or 13kW 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 an additional two hours of propulsion. By adopting this rule as best practise for diesel hybrid cycling, a 50% improvement in fuel economy is common place 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. For more detailed information please contact Beta Marine or Hybrid Marine.
