Nevada Geothermal Power Inc. (NGP) is a dynamic, entrepreneurial and well funded company developing the Blue Mountain Geothermal Field in northern Nevada and actively exploring several other geothermal projects to meet the increasing demand for renewable cost effective energy. Economics and global factors are increasingly aligned behind “green” energy alternatives and the company is well positioned to develop and deliver power production.
How does Geothermal Work? | What is Geothermal Power?
Geothermal power is energy generated by heat stored in the earth. Geothermal companies drill wells down into the earth to utilize this energy to generate power without polluting the environment.
Where is geothermal power found?
Geothermal heat can be harnessed for clean electrical power generation wherever there is high heat flow in deep, fractured rock formations and a shallower, non-fractured or sealed caprock. Resources of geothermal energy range from shallow ground to hot water & hot rock found a few miles beneath the earth’s surface and down even deeper to the extremely high temperatures of molten rock called magma.
What are the 3 types of geothermal power plants?
There are three types of geothermal power plants: dry steam, flash steam, & binary cycle. NGP’s Blue Mountain project will be a binary cycle power plant. The diagram below shows how this plant will work.
How do Binary Cycle Geothermal Power Plants work?
A binary power plant is a closed-loop heat exchange system.
Typical, production wells are drilled down 4,000 to 8,000 feet (1200 — 2400 metres) Hot water (primary fluid) is brought to the surface
The geothermal fluid heat is transferred to a heat-exchanger that contains a secondary fluid that has a lower-boiling point
The secondary fluid is vaporized and used to drive a turbine/generator to produce electricity
The water is then re-injected to recharge the reservoir
The process is continuous.
