Geothermal power utilizes the Earth’s geothermal resources (heat) to generate electricity or other direct applications such as local heating systems. It is an environmentally-friendly form of renewable energy source. Typically, wells are drilled into deep underground aquifers that have been heated by the Earth’s core. The hot water (flash steam power) or steam (dry steam power) from these wells are used to drive turbines in a geothermal power plant to generate electricity. Some newer technologies (such as Eavor™) require the drilling of two side-by-side wells connected in a U-shape. Geothermal energy is used to heat up the circulating fluid like a subsurface heat exchanger.
Nonetheless, the use of deep, high-pressure wells may pose environmental risks such as uncontrolled steam/fluid seepage and surface instability. BGES offers a variety of solutions to geothermal power plants and development projects to ensure safe and environmentally responsible operation.
