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.
Three key reports from the Energy Department address water impacts in geothermal energy production. Two recently issued studies, produced by Argonne National Laboratory for the Department's Geothermal Technologies Office (GTO), highlight methods for economizing water use in geothermal applications. These reports complement a Department-wide report released in June that assesses water usage in multiple energy applications, including geothermal.
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.
A new study commissioned by the Energy Department's Geothermal Technologies Office (GTO) highlights the vast potential for enhanced geothermal systems (EGS) to provide clean, reliable, and sustainable energy to American homes and businesses.
Long-term operation of electronics at high temperatures remains a challenge for the geothermal sector; many downhole sensors are prone to failure when deployed in high-temperature wells, which limits the availability and complexity of logging tools av
MagiQ and Sandia National Laboratory developed a high-temperature wellbore deployment system, which comprises a housing package equipped with a latching arm that mechanically clamps the tool system to the borehole wall. The middle section is the arm that swings out and clamps to the wellbore.
The ability to accurately locate and characterize the release of seismic energy, generated from micro earthquakes(MEQ) is of paramount importance to the development and monitoring of EGS. A small innovative business, MagiQTechnologies Inc. has devel
Geothermal energy – energy derived from the heat of the earth – has the ability to produce electricity consistently around the clock, draws a small environmental footprint, and emits little or no greenhouse gases (GHG).
The Obama Administration's all-of-the-above energy strategy took a leap forward today with the Energy Department's announcement recognizing the nation's first commercial enhanced geothermal system (EGS) project to supply electricity to the grid.
This landmark accomplishment follows two other major DOE-funded technical achievements focused on demonstrating the commercial viability of EGS: The Calpine EGS demonstration at The Geysers in Middletown, California and the AltaRock project at Newberry Volcano near Bend, Oregon.
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.
New geothermal data could open up clean energy reserves nationwide. Scientific American reported that the National Geothermal Data System is helping to isolate geothermal prospects, with the goal of fully profiling geologic and geophysical aspects of these deep energy reserves, which will reduce costly investment by better targeting wells.
As the Geothermal Energy Association (GEA) prepares to release its annual development report at the State of the Geothermal Energy Industry Briefing on February 26 in Washington, preliminary industry data reveals that year-end geothermal growth in 2012 was up 5% from the previous year.
The Geothermal Technologies Program seeks non-prime mover technologies that have the potential to contribute to reducing the levelized cost of electricity from new hydrothermal development to 6¢/ kWh by 2020 and Enhanced Geothermal Systems (EGS) to 6¢/ kWh by 2030.
U.S. Department of Energy investments are tapping a vast resource of clean, baseload energy from the earth's heat, according to Douglas Hollett, Program Manager for the Department's Geothermal Technologies Office. Hollett addressed over 1,000 this week at the annual conference of the Geothermal Resources Council (GRC) in Reno, Nevada—the industry's largest annual gathering of geothermal energy stakeholders in the nation.
At the newly reopened Geysers Geothermal Visitor Center, located in northern California at the largest geothermal complex in the world, the spotlight is on the future of geothermal power. Enhanced Geothermal Systems (EGS) technology—the process of extracting heat from engineered reservoirs through fluid injection into deeper, hotter rock—has the potential to tap an incredible 100+ GW of EGS resource nationwide.
The DOE Geothermal Technologies Program invited the public's input on the technology improvement areas identified at the EGS Technology Roadmapping Information Exchange meeting held in San Francisco, California on August 3-4, 2011.
