A Hybrid Power System Laboratory: Testing Electric and Hybrid Propulsion
IEEE Electrification Magazine, 2019International shipping contributes to a major portion of global emissions. This is expected to grow at a faster pace due to economic and population growth. According to the Third Greenhouse Gas (GHG) Study 2014 of the International Maritime Organization (IMO), the total shipping emissions during 2007-2012 were 3.1% of global CO2 emissions, 2.8% of ...

Non-electric Hybrid Propulsion Systems
2013The introductory section of this chapter describes several devices that may all be classified as short-term storage systems. The use of short-term storage systems in powertrain applications and the possible powertrain configurations are discussed first.

Development of a Hybrid Propulsion System
SNAME Propellers '84 Symposium, 1984For the propulsion of high speed vessels of the semi-displacement or planing type a propulsion system has been designed and tested at model scale which uses partially submerged controllable pitch propellers in semi-ducts for the high speed boost condition. For low speed cruising the same propellers operate fully wetted.

Progress in Marine Hybrid Propulsion Drive Systems
2023 IEEE International Conference on Electrical Systems for Aircraft, Railway, Ship Propulsion and Road Vehicles & International Transportation Electrification Conference (ESARS-ITEC), 2023The paper provides an overview of current marine hybrid propulsion drive solutions, focusing on a particular device for engaging and disengaging the electric motor or diesel engine on the same propeller shaft line. The coupling system is controlled by an overrunning clutch (freewheel type) with ball bearings, allowing a fast change in diesel or ...

Electric and Hybrid-Electric Propulsion Systems
2013While in conventional ICE-based vehicles the energy carrier is a fossil fuel, electric and hybrid-electric propulsion systems are characterized by the presence of an electrochemical or electrostatic energy storage system. Moreover, at least one electric motor is responsible — totally or partially — for the vehicle propulsion.

Fuel-Cell Based Propulsion Systems for Hybrid Railcars
2019 IEEE Milan PowerTech, 2019Railcars for regional no-electrified rail lines typically use powertrains composed by an internal combustion engine coupled to a mechanical transmission. Since they are normally employed on short distances with many stops, different level of hybridization may be considered, in order to recover during braking at least part of the kinetic energy of the ...

New Propulsion System for Hybrid Vehicles
SAE Technical Paper Series, 1993<div class="htmlview paragraph">The search for clean automotive propulsion system has brought to study a new hybrid system. This hybrid system allows the mechanical energy produced by the thermal engine be partly stored in battery pack and partly be sent directly to the wheels without being converted into electrical energy.</div> <div ...

Design of a Hybrid Electrical Propulsion System
52nd AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics and Materials Conference, 2011The focus of this work is on exploring the design of an aircraft hybrid propulsion system by integrating a gas turbine engine with an electric motor assisted by solar power. We discuss how the two systems can work in tandem while optimizing the efficiency.
