Introduction Rising domestic energy needs in the face of limited supplies have led to various estimates of total energy consumption through 1985 and beyond. Increases in domestic energy production sufficient to meet demand by 1985 appear unlikely if energy sources are limited to fossil or nuclear fuel. The intent of this discussion is to delineate and evaluate the geothermal resource base of northern Appalachia, which comprises portions of the states of New York, Pennsylvania, North Carolina, Maryland, Virginia, Ohio, and West Virginia. Total development of geothermal resources in this region could provide additional amounts of energy for electrical provide additional amounts of energy for electrical power, commercial and process heat, valuable power, commercial and process heat, valuable minerals, and desalinated water for the eastern U. S. Geothermal Resource Base Determination of the resource base is supported by the assignment of quantitative values to the following parameters:geothermal gradient, heat flow parameters:geothermal gradient, heat flow in the subsurface, and heat capacity of the rocks. It should be realized that even in the most intensely investigated geothermal areas but few of these values are known, and then often only within an order of magnitude. Geothermal Gradients Fig. 1 illustrates a re-evaluated distribution of geothermal gradient values for northern Appalachia. Unfortunately, these data show only a broad range in the variation of these values (0.7 degrees F/100 ft to 2.1 degrees F/100 ft). Localized high and low gradient values could readily occur within the contours of the map. Heat Flow In-situ heat transfer measurements provide information about the amount of geothermal energy available in the region. The global average measured heat flow is approximately 1.5 HFU (1 HFU = 1 cal/cm2-sec), whereas the average heat flux in the Appalachian system has been estimated to be 1.3 HFU. Local thermal resistivities were re-estimated for various lithological units in Appalachia. Horizontal heat transfer between adjoining rock bodies was ignored. Fig. 2 illustrates the variation of the regional heat flux, which ranges from 0.6 to 1.5 HFU. One area bordering southern West Virginia and western Virginia contains a mixture of anomalous high and low heat flux values. Further field work must be done to resolve the implied geological problem.

Chevron New Energies and Mitsui Oil Exploration (MOECO) signed a joint collaboration agreement to explore the technical and commercial feasibility of advanced geothermal power generation in Japan. The collaboration will study the country's geothermal resource potential and evaluate the effectiveness of advanced closed loop (ACL) technology for a future pilot project in Japan. Unlike conventional geothermal projects, which use traditional steam turbines requiring high temperatures often found in concentrated locations limited by geological characteristics, ACL can potentially enable access to geothermal resources at a wider range of temperatures and geologies, according to the companies. "This collaboration provides an opportunity for Chevron to combine its subsurface capabilities and technologies with MOECO's intimate knowledge of Japan's geothermal potential resource geology and its long history of responsible resource development," Barbara Harrison, vice president of offsets & emerging, Chevron New Energies, said in a statement. "The joint team will have the opportunity to test emerging geothermal technology in a real-world setting with significant scaling up potential."
