Reduced diesel consumption in a hybrid generation system with an electric turbocharger


  • Electric power generation in remote communities represents a technological challenge that must take into account environmental requirements in terms of GHG emissions and production costs while ensuring continuity of energy supply to consumers.
  • Among the resources used in these areas are renewable energy and diesel generators. The latter often operate at low loads characterized by poor performance and high operating and production costs.
  • The purpose of this invention is to improve the diesel generators performance (brake specific fuel consumption – BSFC) and increase the penetration rate of renewable energy in remote communities or energy isolated areas in general, thus reducing overall fuel consumption.
  • The energy required for the proposed system will be provided by excess production during periods when available wind or solar power exceeds demand, often dissipated or used for heating.

Technology Overview

  • Storage of excess renewable energy in the form of electrochemical energy (deep discharge battery)
  • The stored electrical energy is used to drive an electric motor that will drive the turbocharger to provide the optimal amount of air at the intake.
  • Add a turbo compressor driven by an electric motor or modify the turbo compressor that exists in most generators by adding an electric motor.
  • Technology developed by Prof. Adrian ILINCA and Sami AYADI (Department of Mathematics, Computer Science and Engineering, L’Université du Québec à Rimouski (UQAR)).

Competitive advantages

  • Reduced fuel consumption
  • Increase the penetration rate of renewable energies in the energy systems of isolated sites.
  • Improve the performance of diesel engines operating at low loads: efficiency, fuel consumption, GHG emissions, rated operating temperature, proper lubrication, etc.
  • Similar overcharging technique is not yet used in energy systems in remote communities but it is used in vehicles.
  • Design for retrofit of existing diesel generators
  • Less volume compared to other solutions
  • Relatively low costs and rapid return on investment
  • Downsizing possibility (use a diesel generator of lower rated power with pneumatic hybridization to increase maximum output power)

Market applications

  • Oil companies
  • Remote Communities
  • Service stations on highways
  • Mining industry
  • Road, rail and naval transport

Business opportunity 

  • Technology available for licensing
