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 105T 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 6kW of power capability.
Which when added to the standard engine twin 60 Amp domestic battery alternators equates to a maximum of 9kW 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 V twin motor/generator assembly which provides a total of 20kW of electric propulsion and when in generation mode a total of 12kW of power capability.
Again factoring in the standard engine twin 100 Amp domestic battery alternators a maximum of up to 16kW 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.

Our Hybrids can use many different battery technologies this includes, Lead/Acid, AGM and Lithium. For inland craft the most appropriate technology is wet lead/acid cells. These batteries are very robust, provide long and reliable service (5 year warranty and 10 year expected life) and are cost effective. For safety we standardise on a low voltage 48v battery bank with a combined watering and venting system. The batteries can be toped up from a central watering point and safely vent charging gasses directly overboard.
The battery bank size is typically 15 to 30kWh and provides energy for both propulsion and house domestic loads. Using powerful inverter technology, you can run all the electrical domestic appliances you would expect at home and eliminate the need for gas on board (electric cooking).
The 30kWh battery bank can 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.
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.
