In 2013, Sandia National Laboratories (SNL) successfully completed the development of a high-temperature drilling technology able to withstand the harsh conditions present in geothermal reservoirs. SNL developed and tested a high-temperature downhole motor that includes an indexing tool for use with commercially available percussive hammers. Conventional pneumatic down-the-hole-hammer drilling systems—widely used in the mining and oil and gas sectors—perform well in hard rock environments and are capable of removing a volume of rock with low energy input.
The United States Department of Energy announced new $31 million geothermal field laboratory dedicated to cutting-edge research in enhanced geothermal systems (EGS). Called the Frontier Observatory for Research in Geothermal Energy (FORGE), this effort could unlock access to enough clean geothermal energy to power 100 million homes in America.
The Office of Energy Efficiency and Renewable Energy, U.S. Department of Energy, is seeking applications for the permanent position of Director to lead a national program in the development of innovative geothermal technologies that advance geothermal's role in the U.S. energy portfolio.
Doug Hollett, director of the Geothermal Technologies Office (GTO), was promoted to Deputy Assistant Secretary, Renewable Power, on November 21 and assumed responsibility for the Solar, Wind and Water, Geothermal, and Grid programs within the Office of Energy Efficiency and Renewable Energy (EERE). Hollett directed the GTO for three years, providing both technical and project oversight for new technologies designed to advance geothermal’s role in the U.S. energy portfolio.
The Energy Department announced funds targeted to small businesses in two separate geothermal subtopics: a) innovations to develop under-utilized markets and b) a technology transfer opportunity for coproduced geothermal resources. An informative webinar will cover the geothermal topic on Friday, November 7, at 1:30 pm.
The Geothermal Energy Association (GEA) announced today the winners of their 2014 GEA Honors, which recognizes companies, projects, and individuals who have demonstrated outstanding achievement in the geothermal industry. The winners were selected in categories including Technological Advancement, Economic Development and Environmental Stewardship. Now in its fourth year, GEA also provides special recognition of companies and individuals who have made notable advances and achievements for geothermal energy.
A new DOE report, published by the National Renewable Energy Laboratory, highlights findings from a review of five policy mechanisms that have been successfully applied to hydrothermal exploration activities around the globe – loan guarantees, drilling failure insurance, lending support, grants, and government-led exploration – and their applicability to the U.S. geothermal market.
The Energy Department today announced commercialization of a rechargeable energy storage device capable of operating in the extreme temperatures necessary for geothermal energy production. Industry partner FastCAP Systems successfully demonstrated an ultracapacitor that is fully operational in 200°C conditions, extending the upper limit of high-temperature energy storage and electronics, and engineering a flexible system that could reduce cost and risks of geothermal drilling.
This data visualization shows how industry can model geologic features from free, open-source data through the National Geothermal Data System. In this fence diagram, Schlumberger utilized bottom hole temperatures from the National Geothermal Data Systems (NDGS) on-line platform to supplement subscription data temperatures used to create basin-wide 3D temperature models in Petrel Exploration and Production software.
The 2013 Geothermal Technologies Office Peer Review Report is now available for download. The report provides a summary and compilation of expert, independent technical feedback on GTO-funded projects, as well as feedback from the Peer Review reviewers.
Scientists at the Energy Department's Pacific Northwest National Laboratory (PNNL) have made a commercially viable discovery: how to capture substantially more heat from low-temperature resources. In a market where binary working fluids are costly
The Bureau of Land Management (BLM) and the U.S. Forest Service Inyo National Forest on August 13 signed the Record of Decision approving a new 40-megawatt geothermal project near Mammoth Lakes, California.
As part of a geothermal exploration effort to search for geothermal resources nationwide, a $5 million U.S. Department of Energy investment to Calpine Corporation this year culminated in the confirmation of an initial 11.4 MW of equivalent steam — 50% more than early estimates — from three previously abandoned wells at The Geysers geothermal field in northern California.
New geothermal prospects in the western United States show promise, according to the new 2013 Annual U.S. Geothermal Power Production and Development Report, published by the Geothermal Energy Association this week.
