Geothermal technologies use thermal and sustainable clean energy of the Earth. Geothermal resources include heat retained in the soil at shallow, warm water found a few kilometers from the subsurface of the earth and extremely high temperatures of molten magma deep underground.
Hydraulic fracturing is most well known in the natural gas arena, however one company is hoping to change that. Using an existing well that had become unproductive, high-pressure water, 800psi to 1000psi, was injected to fracture the rocks with a hope of allowing enough water to circulate in order to make the process economically feasible.
