The definition describes a hybrid-drive as a propulsion system, which consists out of two different drive-systems. For this purpose at least two energy converters and energy storages must be in use. Apart from some exceptions preferably combustion engines and electric motors are combined into a hybrid-drive.Dutch Veth Propulsions Technical Director Marco Huisman: ”The innovation on this new system is that two different drives are used. The Veth Propulsion hybrid drive offers a lot more solutions for drive profiles, because of its combination of diesel and / or electric motor propulsion. Both drives can be used within their optimal system effectiveness curve. This offers all benefits of a diesel electric drive without any disadvantages.
The hybrid drive features moreover an additional advantage: the asynchronous electric motor can also be used as a generator. In doing so it does not cost any additional fuel compared to a separate running gen-set which runs in low idle &nda... [More]
Propulsion of yachts and boats up to 24 meters (78.7 ft) may be revolutionised if the outcome of the three-year €2 million European Union financed R&D project ‘High Efficiency Hybrid Drive Trains for Small and Medium-sized Marine Craft’ (project acronym – ‘HYMAR’) bears fruit. Reduction of GHG emissions from tens of thousands of small craft attracted the European Union’s support for the project.The R&D target is to come up with a fully integrated, computer controlled diesel-electric hybrid drive configuration that will take over the traditional role of the diesel engine as the direct drive of sailboats and small commercial vessels.At the centre of the system under development is a comprehensive Energy Management Module (EMM) to synchronise and control all the energy flows (generator, wind, trailing propellor, solar panels) in and out of a specially designed battery bank.
