Download or read book Mining the Earth s Heat Hot Dry Rock Geothermal Energy written by Donald W. Brown and published by Springer Science & Business Media. This book was released on 2012-04-23 with total page 669 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mining the Earth's Heat: Hot Dry Rock Geothermal Energy describes the work carried out by the Los Alamos National Laboratory to turn an idealistic concept - that of drawing useful amounts of energy from the vast underground store of hot rock at reachable depths - into a practical reality. This book provides comprehensive documentation of the over two decades of experiments carried out at the test site at Fenton Hill, New Mexico, where the feasibility of accessing and extracting this vast natural resource was finally demonstrated. It also discusses the numerous technical, administrative, and financial hurdles that had to be overcome along the way. This publication will no doubt prove invaluable to researchers around the world as they strive to move this now-proven technology toward commercial viability. In addition, it is a valuable source of relevant information for anyone interested in the world energy outlook for the 21st century and beyond.

Book excerpt: The extraction of heat or thermal energy from the Earth -- heat mining -- has the potential to play a major role as an energy supply technology for the 21st century. However, even if reservoir stimulation goals are achieved, the role of heat mining with today's energy prices and development costs is limited to only a small fraction of the earth's surface, specifically to geologically active regions where geothermal gradients are high. This paper examines the prospects for universal heat mining and the types of developments required to make it a reality. A generalized multi-parameter economic model was developed for optimizing the design and performance of hot dry rock (HDR) geothermal systems by linking an SQP nonlinear programming algorithm with a generalized HDR economic model. HDR system design parameters selected for optimization include well depth (or initial rock temperature), geofluid flow rate, number of fractures and injection temperature. The sensitivities of the optimized design parameters, HDR system performance, and levelized electricity price to average geothermal gradient, fractured area/volume, maximum allowable geofluid temperature, reservoir flow impedance, well deviation, and fracture separation have been investigated. Key technical and institutional obstacles to universal heat mining are discussed in a more general context. These include (1) developing methods for stimulating low permeability formations to provide sustained productivity with acceptable flow/pressure losses (2) dealing with barriers to change primary energy supply options when fossil energy resources are abundant and prices are low and (3) lowering the high drilling costs for developing the deep (>5 km) reservoirs required in low gradient areas. Advanced concepts in drilling technology that could lead to a linear as opposed to exponential relationship between cost and depth are discussed in light of their potential impact on heat mining.

Book excerpt: Harnessing the heat from the earth - The story of geothermal energy Our planet is a hot place, with volcanoes erupting and geysers spouting. But there's also a hidden fire burning inside the earth. This is geothermal energy, the heat and energy that is generated from within the earth. It is a renewable source of energy that can be used to heat homes, provide light, cook food, and even power vehicles. Deep within the earth, the decay of radioactive elements and the movement of tectonic plates generate heat. This heat warms rocks and water, which rise to the surface and create geothermal phenomena. These include volcanoes, hot springs, and geysers. We can use these natural phenomena directly, or we can extract the heat and water from beneath the earth using specialized technology, and use it to generate electricity and for other purposes. Direct use of geothermal energy Direct use of geothermal energy is the simplest and most common way to harness this renewable resource. It involves using the natural heat that comes from the earth to warm homes, businesses, and other buildings. Geothermal heat can also be used to heat water for bathing, cooking, and other purposes. Geothermal power generation Geothermal power generation is a more complex process, but it can be a very efficient way to produce electricity. It involves drilling wells into the earth to extract hot water or steam. This water or steam is then used to drive a turbine, which generates electricity. The benefits of geothermal energy Geothermal energy has many benefits over other sources of energy. It is a renewable resource, meaning that it will never run out. It is also a clean source of energy, producing no emissions that contribute to climate change.
