Imagine using the natural heat of the earth as an energy source that is renewable, stable, and free of carbon dioxide emissions. Geothermal drilling makes this possible. This process creates boreholes that siphon geothermal energy—heat energy that is created and stored in the earth. Geothermal energy is clean and sustainable. When compared to the Earth’s overall temperature, the heat extracted during the drilling process is minimal.

How Extraction Works

During the extraction process, high-temperature water- or steam-dominated reservoirs are often used. These wells can range from 150 to 400 feet deep, meaning they require a site with a considerable amount of space. Hot water is first pumped from the subsurface using one or more boreholes. A heat exchanger then transfers this heat to its next destination, while the remaining (now cooled) water is pumped back into the earth.

When no water is available, a heat-conducting liquid is circulated through a pipe system and into the subsurface instead. The liquid gradually heats up as it circulates through this hydrothermal system and extracts heat from the surrounding layers of rock, magma, and sediment.

The Benefits of Drilling

Many residences and commercial buildings are beginning to use geothermal drilling to install heat pump systems for heating and cooling. The main benefit of these systems is that, instead of relying on the earth’s natural resources, it uses the planet’s ability to absorb heat to supply energy. It provides an efficient and eco-friendly HVAC alternative that helps homeowners save money on utility costs.
