Solar Hydel Hybrid Power Stations

We hear a lot of fuzz about solar-wind hybrid power plants. Its surprising why there’s no major projects which utilize solar energy to multiply the output from an existing hydro electric power station.

A solar-hydel hybrid plant would work, in a very basic sense, as below –

  1. Photo voltaic panels are deployed in arrays supported on floating barges in the reservoir. (OR on barren land if available in proximity)
  2. Additional penstock-turbine-generator circuits are built for the EXTRA power to be generated.
  3. A sump collects the water used by the NEW water circuits described in step 2.
  4. Solar energy created by the PV arrays are used by several DC motors to pump the water from sump back to the reservoir.

(Detailed design will involve output power, back-up duration, fluid flow losses etc as design parameters.)

This method has these advantages –

  1. Removes the need of batteries which are expensive to procure and maintain too. Instead here solar energy is stored as potential energy of water.
  2. Removes theĀ  need for expensive power electronics for DC to AC conversion.
  3. Reduces evaporation losses of water from reservoir considerably.
  4. Reduces the need for new Dams for increasing power generation.

  1. I am an individual innovator and doing research from last 30 years on non

    conventional energy resources, energy conservation and improvisation of

    existing system. In this regard still I am working on my concepts and

    developing new techniques for energy generation and its storage system. My

    concept on energy generation is very unique, special and economic. In a

    single system we can convert any type of movement into energy and store as

    a fuel for a long time and transport it very easily. We can generate power

    in huge quantity whenever and wherever we require.

    I have developed an energy storage system other then battery, developed an

    ocean wave converter (O W C) on above storage system by which we can

    convert the power of ocean wave with the help of gravity into energy and stored it as fuel for further use in

    very low cost. We can provide employment 20 families by using every 1 km. coastline.
