Available in PDF, EPUB and Kindle. Book excerpt: Economically feasible uses for geothermal heat at temperatures too low for conventional electrical power generation at present are delineated. Several geothermal resource areas in northern California that have development potential are described, and applications of the heat found in each area are suggested. Plates are included of the following field study areas: the east side of the Sierra-Cascade Range north of Bishop, and the northern Coast Range from San Francisco Bay to Clear Lake. The counties included in the study area are Mo doc, Lassen, Sierra, Plumas, Placer, Alpine, Mono, Mendocino, Lake, and Sonoma. (LBS).

Available in PDF, EPUB and Kindle. Book excerpt: The California Energy Commission has been sponsoring investigations of the geothermal resource in Clearlake, California. Studies have included preliminary work by Blaydes and Associates (1985), which incicated there was the potential for a resource beneath the city and five construction projects which could utilize geothermal energy, and a study by Papadopulos and Associates, which included a three meter temperature survey, a soil-radon gas survey, drilling of four 500 foot temperature gradient holes and interpretation of the work. Additional work, consisting of water chemistry, is currently underway. The work, to date, suggests there is a geothermal anomaly beneath the city. The temperature is expected to be 158 to 167F and the depth about 2,000 feet. The source of the warm water is unknown but the up-flow zone may be north or northwest of the temperature gradient holes. Maximum temperature encountered in the gradient holes was 96F in CL-4 at a depth of 125 feet. Temperature reversals were encountered in all the gradient holes. Temperature reversals usually indicate hot water leaking up a fault located up hydraulic gradient from the well and flowing along a permeable zone. If the fault can be located and intersected, hotter water can often be obtained; how much hotter would depend on the distance and how much the fluid has cooled or mixed with cooler water. The California Energy Commission funded this brief study to evaluate the potential for application of the inferred resource for district heating and/or other uses. This study consisted of the evaluation for district heating the area bound by Olympic Drive on the north, Old Hwy. 53 on the east and the lake on the southwest. This area was selected because it is near the temperature gradient holes in an area of elevated three meter temperatures and near fault intersections which are likely to serve as conduits for geothermal water to rise from depth. It is also near several projects noted in the Blaydes report.

Book excerpt: This report ranks and describes California's geographic and end-use markets which could directly use low and moderate temperature geothermal resources are ranked and described, as well as those which have the highest potential for near-term commercial development of these resources. Building on previous market surveys, the assessment determined that out of 38 geothermal resource areas with characteristics for direct use development, five areas have no perceived impediments to near-term development: Susanville, Litchfield, Ontario Hot Springs, Lake Elsinore, and the Salton Sea Geothermal Field. Twenty-nine applications were compared with previously selected criteria to determine their near-term potential for direct use of geothermal fluids. Seven categories were found to have the least impediments to development; agriculture and district heating applications are considered the highest. Ten-year projections were conducted for fossil fuel displacement from the higher rated applications. It is concluded that greenhouses have the greatest displacement of 18 x 106 therms per year.

Available in PDF, EPUB and Kindle. Book excerpt: The California Energy Commission's (CEC) Geothermal Program has, in the past, focused on electrical generation. Recently the Program has begun a transition from power generation towards commercialization of nonelectric, direct use applications. This procession was influenced by the commercialization of electrical generation technology at The Geysers and the extensive development activities in Imperial Valley. Further, little progress has been made to develop California's low- to moderate-temperature geothermal resources for direct use applications despite their abundance and the commercial availability of the technology and associated equipment. In order to stimulate the market for direct use applications, the CEC has funded, or is in the process of funding, feasibility and design studies for 11 geothermal direct use projects. These studies are intended to assess and demonstrate the technical and economic feasibility of using geothermal energy for a variety of direct use applications. If the studies prove feasible and the projects constructed, the energy saved would be the heat equivalent to almost 200,000 barrels of oil per year. More importantly, since 46 of California's 58 counties have indications of hot water resources, these projects offer significant opportunity for replicability throughout the State representing an even greater energy savings potential. This package provides a description of each of the studies along with a map locating the study sites and potential resource areas in California where such projects might be possible.

Available in PDF, EPUB and Kindle. Book excerpt: The Sonoma Valley area contains low-temperature geothermal resources (20 C ≤ T ≤ 90 C) having the potential for useful development. Sonoma Valley residents, local governments and institutions, private developers, and manufacturers may be able to utilize the geothermal resources as an alternate energy source. Historically, there have been at least six geothermal spring areas developed in the Sonoma Valley. Four of these (Boyes Hot Springs, Fetter's Hot Springs, Agua Caliente Springs, and the Sonoma State Hospital warm spring) lie on a linear trend extending northwestward from the City of Sonoma. Detailed geophysical surveys delineated a major fault trace along the east side of the Sonoma Valley in association with the historic geothermal areas. Other fault traces were also delineated revealing a general northwest-trending structural faulting fabric underlying the valley. Water wells located near the ''east side'' fault have relatively high boron concentrations. Geochemical evidence may suggest the ''east side'' fault presents a barrier to lateral fluid migration but is a conduit for ascending fluids. Fifteen of the twenty-nine geothermal wells or springs located from literature research or field surveys are located along or east of this major fault in a 10 km (6.2 miles) long, narrow zone. The highest recorded water temperature in the valley appears to be 62.7 C (145 F) at 137.2 meters (450 feet) in a well at Boyes Hot Springs. This is consistent with the geothermal reservoir temperature range of 52-77 C (126-171 F) indicated by geothermometry calculations performed on data from wells in the area. Interpretation of data indicates a low-temperature geothermal fluid upwelling or ''plume'', along the ''east side'' fault with subsequent migration into permeable aquifers predominantly within volcanic strata. It is quite likely other geothermal fluid ''plumes'' in association with faulting are present within the Sonoma Valley area. A 5.8 km2 geothermal zone, that parallels the fault trace, is delineated and is perhaps the most favorable area for further investigation and possible geothermal production.
