Power from Renewable Energy

MHD Power Plant Working Principle: MHD Power Plant or Magneto Hydro Dynamic is concerned with the flow of a conducting fluid in the presence of magnetic and electric field. The fluid may be gas at elevated temperature or liquid like sodium (or) potassium. MHD Power Cycle Principles: Faraday’s law of electromagnetic induction states that a […]

Fuel Cell Working Principle and Schematic Diagram: Fuel Cell Working Principle explains that it is an electrochemical device that converts chemical energy of a conventional fuel directly into low voltage D.C. electrical energy. It is then described as a primary battery in which fuel and oxidizer are stored external to the battery and fed to

Biogas Power Plant Working, Site Selection and Application: Introduction – Biogas is a combustible gas mixture of methane, carbon dioxide, water and hydrogen sulphide produced during the anaerobic decomposition of organic matter. During anaerobic digestion, wastes are treated and degraded and biogas is produced. Anaerobic treatment also has the advantage over aerobic treatment of a

OTEC Power Plant: Introduction – OTEC Power Plant or Ocean Thermal Energy Conversion is an energy technology, which uses the ocean’s natural temperature gradient to drive a turbine, which is connected to a generator. It is desirable that the temperature difference between the warm surface water and the cold deep water in sea should be

Geothermal Power Plant Working Principle: Geothermal Power Plant Working Principle – The growing demand of power will exhaust all fossil fuel sources in few decades. Therefore there is a permanent need for unconventional energy sources such as sun, wind, tidal and geothermal. The geothermal energy has a great potential and is being commercially exploited in

Types of Solar Power Plant: The surface of earth receives energy of 1014 kW from the sun. It is evident that sun will last for 1011 year. Even though the sun light is filtered by atmosphere, for every one square meter of land exposed to direct sun light receives the energy of 1 HP (or)

Pumped Storage Power Plant – Operating Modes and Types: Introduction – Pumped Storage Power Plant are generally used for peak loads. An interconnected system of pumped storage plants are more suitable, when the quantity of water available for power generation is insufficient in peak period and also highly suitable for areas of high dam construction. Pumped

Tidal Power Plant – Types and Working Principle: Introduction to tidal power plant – Gravitational force between the moon, the sun and the earth causes the rhythmic rising and lowering of ocean water, around the world that results in tide waves. The moon exerts more force (twice) on the tides as the sun exerts, due

Wind Energy and Wind Power Plant: Wind is a form of solar energy. It is caused by the uneven heating of the atmosphere by the sun due to the irregularities of the earth’s surface, and rotation of the earth. Wind flow patterns are modified by the earth’s terrain, bodies of water, and vegetative cover. The

Turgo Turbine Working Principle: The Turgo turbine is an impulse water turbine designed for medium head applications. Operational Turgo Turbines achieve efficiencies of about 87%. It works with net heads between 15 and 300 m. It is a modification of the Pelton wheel, the Turgo Turbine has some advantages over Francis and Pelton designs for
