EGS

According to the Global Geothermal Power Tracker (GGPT), a comprehensive dataset of geothermal power facilities, about 14 GW of geothermal power is operational worldwide. The U.S. has the largest installed capacity at 3,900 MW, followed by Indonesia (2,418 MW), the Philippines (1,952 MW), Türkiye (1,691 MW), New Zealand (1,042 MW), and Kenya (985 MW). Most […]

Sage Geosystems will build a first-of-its-kind 3-MW geothermal baseload power and energy storage system on land owned by San Miguel Electric Cooperative (SMECI) in Christine, Texas. The company plans to begin operating the project later this year to supply the Electric Reliability Council of Texas (ERCOT) grid. The project will mark the first commercial-scale deployment […]

Next-generation, or “next-gen,” geothermal resources have the potential to increase geothermal power generation in the U.S. by twenty-fold by 2050. Next-gen geothermal concepts use technologies developed by the oil and gas industry to engineer reservoirs for geothermal energy generation, vastly expanding the available resource base. Typically, the term next-gen geothermal refers to enhanced geothermal systems […]

Enhanced geothermal systems (EGS) have long held promise. New developments suggest dramatic progress may be on the horizon. Can innovation feasibly overcome technical and economic hurdles that have

A pioneering 3.5-MW enhanced geothermal system (EGS) in northern Nevada that demonstrated the ability to drill, complete, and operate horizontal wells is now operational. Project Red, co-developed by Fervo Energy and Google under a partnership forged in 2021 under the “world’s first corporate agreement to develop an enhanced geothermal power project,” is supplying power to […]

The spectrum of geothermal technologies is quickly evolving. This supplement to POWER’s April 2023 feature, “Startups Are Shaking Up Geothermal Power’s Potential,” briefly explains the differences between some engineered geothermal systems. Conventional geothermal energy is largely produced by hydrothermal systems, which consist of hot water circulated in deep-seated permeable rocks. Resource temperature ranges from high (greater […]

The Department of Energy has moved to fund up to seven pilot enhanced geothermal system (EGS) projects to demonstrate different geologic settings, a variety of development techniques, and different well orientations. The U.S. agency on Feb. 8 announced up to $74 million to support the EGS pilots, for which the November 2021–enacted Infrastructure Act designates […]

The Department of Energy’s (DOE)’s latest Energy Earthshot will seek to cut the cost of enhanced geothermal systems (EGS) to $45/MWh by 2035, an ambitious goal that would shave current EGS costs by 90%. The DOE’s latest Energy Earthshot—part of a 2021-research, development, and demonstration (RD&D) initiative it launched to accelerate breakthroughs for emerging technologies—will […]

A federally backed effort to advance enhanced geothermal system (EGS) technologies in Utah marked a significant milestone with successful completion of its first large-scale 10-day stimulation in a deep-deviated well. The U.S. Department of Energy’s (DOE’s) Utah Frontier Observatory for Research in Geothermal Energy (FORGE), which is sited near the town of Milford on the western […]

After several years of stagnancy, prospects for the geothermal power industry are heating up. Over the past year, it has seen a flurry of legislative boosts, an uptick of power purchase agreements, and
