AI Technical Summary
Existing technologies struggle to harness electricity generation from geothermal water under pressure effectively, particularly when it does not produce steam, and distinguishing between geothermal pressure and hydraulic head can be challenging.
Utilizing geothermal pressured water to drive a Roots-type water wheel, which is connected to a speed increaser and a generator, allowing energy extraction even when the water is not converted to steam.
Enables efficient energy generation from geothermal water pressure without steam conversion, addressing the challenge of distinguishing between geothermal and hydraulic sources, and utilizing undersea hydrothermal vents and hot spring water for power generation.
Abstract
Description
[Technical Field]
[0001] The present invention relates to the generation of electricity from geothermal pressurized water. Summary of the Invention [Problem to be solved by the invention]
[0002] Generate electricity using geothermal water under pressure.
[0003] The geothermal pressured water turns a Roots-type water wheel, which then drives a speed increaser and a generator.
[0004] The pressure from the geothermal heat can be utilized even when it does not become steam, and energy can be obtained.
[0005] Geothermal pressured water drives a Roots-type water wheel, a step-up gear and a generator.
[0006] The process of introducing geothermal pressurized water into the pipes is the same as in conventional geothermal power generation.
[0007] In some cases, it is difficult to distinguish whether the cause is geothermal water pressure or hydraulic head. On flat ground, on mountains, or in excavations deep underground, the cause is geothermal. On the seabed, the cause may be geothermal or molten material (see below).
[0008] Water associated with undersea hydrothermal vents can also be used.
[0009] Water that is being introduced into the hot spring can be used (although care should be taken to avoid water contamination).
[0010] Geothermal pressure water flows long distances and its temperature drops. If it is driven by water pressure, it can be used in the same way.
[0011] In particular, the strength of the acidity and sulfur content indicates that it comes from high-temperature geothermal reservoir water.
Claims
1. A facility that generates electricity using geothermal pressured water.
2. A facility that generates electricity using water pressurized by geothermal heat from beneath the seabed.
3. Among the contents of claim 1 above, this uses water that is on its way to being supplied to a hot spring.
