Geothermal energy is one of many possible alternatives to the modern fossil fuel industry. Geothermal energy uses the heat of radioactive particles below the Earth’s surface, which is produced in the form of hot water and steam.
Most underground temperatures are used directly for heating and cooling systems. The advantage of geothermal systems is that they provide direct heating and cooling, thus reducing the burden on other renewable sources, wherever they are found in the world, but are widely exploited. As a result, most geothermal power plants are concentrated in small areas, in the corners of the world.
The Earth’s internal heat does the work to create the vapor we inhale. The planet gets its internal heat from pressure and density, as well as from the Sun. When the power is on, the pumps pump water back into the ground through a system of injection wells. Returning the product is safe and completes the cycle that makes geothermal energy a renewable energy source. There are three main methods of converting geothermal resources into electricity: dry steam, flush steam, and the binary cycle.
Binary Cucle Plants
Development of advanced setups. Loop plants use oil to heat and produce secondary water (usually isobutane).
This secondary water boils with air, which drives a turbine that produces electricity through an electric generator. This water is then cooled and recycled for reuse.
Heat from geothermal energy is lost, but the water returns to the ground where it can be reheated. This makes it safe and environmentally friendly without polluting the water cycle.
Flash Steam Plants
These power plants also use hot water directly.
Geothermal hot water is pressurized in a reservoir. This tank is known as the ‘flash tank’. Since the tank is colder than the outside temperature, the water inside evaporates.
This turbine then drives the turbine. The water vapor is condensed back into fresh water and then injected into the ground.
The purpose of this system is to produce instantaneous energy by multiplying the energy. This also allows the factory to control the production of long-lasting machines.
Dry plants
The first and most common geothermal power plant is the dry model.These plants directly pipe steam from a reservoir into a turbine. The turbine spins and the steam condenses as it cools. The resulting water is then recaptured and injected back into the ground.
This model is cheap to make and straightforward in its engineering. The downside, of course, is that they are less efficient than others mentioned here.
There is a lot of potential for geothermal systems, but progress in this area is slow compared to other energy sources. If geothermal is to replace oil and gas as the dominant renewable energy source within the next three decades, significant efforts will need to be made to develop the necessary drilling and monitoring technologies that outperform conventional systems.
