Biomass electricity generation can come in many forms. The most common method is as simple as burning wood or wood pellets to heat a boiler steam to turn a turbine.
In a thermal power station, fuel (coal or natural gas) is burned in a boiler to convert water to steam.
Cogeneration is the simultaneous production of electricity and steam from a single fuel source using combustion gas turbines, heat-recovery steam generators and steam turbine technology.
Geothermal power generation passes hot water through an exchanger and creates steam and drives a turbine to produce electricity.
Hydroelectricity is created by falling water. Water from reservoirs flows through the penstocks that connect the reservoir to the station. The water turns a hydraulic turbine, which rotates a generator and produces electricity.
Natural Gas Stations
In a natural gas power station, simple cycle gas turbines inject compressed air into a combustion chamber, along with fuel, to produce a high pressure hot gas stream that is expanded in a turbine to produce electricity. The expanded gas products are exhausted directly to the atmosphere.
Solar power uses panels to capture and store energy from the sun – it’s one of the cleanest technologies out there but is still very expensive and, of course, only works when the sun is shining.
Wind turbines capture the kinetic energy available from wind and convert it into electrical energy. Large blades mounted on tall towers rotate a shaft connected to a gearbox and generator to produce electricity.
