Geothermal Energy

Question: Please explain geothermal energy. Does BTL Liners produce liners for the geothermal industry? Answer: Simply put, geothermal energy uses the internal energy and heat of the planet to create electricity. The amount of heat within 10km of the Earth's surface contains 50,000 times more energy than all the oil and natural gas resources in the world! Tapping even a fraction of the thermal energy from deep within the Earth is one of the more promising methods of producing sustainable power. The harnessing of geothermal energy is relatively simple. Once a hot water source is located, a well is constructed which draws hot water (or steam) up from within the earth and uses that hot water to power turbines and produce electricity. In some cases, where there is not a suitable water source, technology is being developed to fracture the dry rock deep underground and pump water down (similar to hydraulic fracturing in the oil & gas industry) to become heated and then return to the surface. Hot water from deep underground can hold trace amounts of toxic elements such as mercury, arsenic, boron and even lithium, in some cases. These chemicals precipitate as the water cools, and can cause environmental damage if released. In early geothermal developments, such wastewater was disposed of in surface ponds or rivers, but now it is almost universal practice to inject the cooled water through wells back underground where it rejoins the thermal system. This injection minimizes the chance of contaminating surface waters, and also replenishes the water that sustains the hydrothermal system. BTL's specialty is containment—we provide the liners needed to ensure that water awaiting reinjection does not escape to harm the environment in any way. Geothermal energy is one of the least expensive, cleanest, and most reliable sustainable power sources available. BTL Liners is proud to be involved in such sustainable green energy efforts!
