A hybrid electric vehicle (HEV) is a type of hybrid vehicle and electric vehicle that combines a conventional internal combustion engine (ICE) propulsion system with an electric propulsion system (hybrid vehicle drivetrain). The presence of the electric powertrain is intended to achieve either better fuel economy than a conventional vehicle or better performance. There are a variety of HEV types, and the degree to which each functions as an electric vehicle (EV) varies as well. The most common form of HEV is the hybrid electric car, although hybrid electric trucks (pickups and tractors) and buses also exist.

    During COP23, the Centre provided country Parties and other stakeholders with a platform to discuss progress and trends in technology transfer in terms of bridging gaps between countries' technology planning and the innovators and financiers implementing technology solutions. Below, you'll find a selection of presentations from various CTCN events at COP23.

    As a government-funded research institute under the Ministry of Science, ICT and Future Planning of the Republic of Korea, the mission of Korea Institute of Materials and Science KIMS is to comprehensively facilitate R&D, test, evaluate and provide technical support in order to promote innova

  • Objective

    The smart grid is the state-­‐of-­‐the-­‐art technology for electrical system that can sensibly execute the operations to all interconnected elements -­‐ from generator to consumers. Smart grid simply converts the conventional power grid towards the modern grid in order to regulate sustainable, economic and reliable electricity (Massoud &Wollenberg, 2005 and Gellings, 2009). Smart grid intelligently executes operations from primary and secondary generators through the transmission and distribution network to the different types of consumers.

    Objective

    The advent of electric vehicles (EVs) promises to be

    a game-changer for the world’s shift to sustainable

    energy and particularly to renewable power generation.

    This is true for several reasons. Most notably, along

    with transforming the transport sector, EVs present a

    viable opportunity to introduce much higher shares of

    renewables into the overall power generation mix.

    EV charging can create significant additional electricity

    demand. This can be met practically and cost-effectively

  • Vehicle to Grid (V2G) involves using excess battery power from electric vehicles such as Battery Electric Vehicles and Plug-in Hybrid Electric Vehicles to help balance the load of localized power grid segments during peak hours. The storage in electric vehicles has not been used previously by the electric grid. There has never been any business that negotiates between grid operator power need and automobiles.

  • Microbial fuel cells (MFC) or electrochemical or biological cells are used to convert biomass material into liquid fuel and ultimately into electricity. They convert chemical energy into electrical energy through the catalytic reaction of micro-organisms. This process occurs in nature and researchers have had difficulty effectively and efficiently duplicating the process. MSU’s invention is an electrochemical cell that can be used to convert biomass material to liquid fuel electricity.
