Alaska RIG inviting: All with interest in geothermal in Alaska are welcome!

Description
If you are coming to GRC2025, please come to our next Alaska RIG event at the Peppermill Resort, see notice at Registration, Sunday, October 26, 2025, 4:00 - 6:00 pm. John Eichelberger, RIG leader and Geothermal Program Manager at Alaska Division of Geological and Geophysical Surveys, will provide a short, informal, illustrated summary of geothermal energy in Alaska, beginning at 4:30 pm. This will be followed by an open mic (and screen) for anyone with news, ideas, or questions for the group, or if you just want to introduce yourself and your affiliation. You're also welcome to send a slide or two to John (john.eichelberger@alaska.gov) to be part of the show, if you like, or just grab the mic. Hope to see you there!

NM RIG Virtual Event: Unlocking the Benefits of Community Geothermal

Description
Celebrate World Geothermal Day with the New Mexico RIG! Join us for an informative webinar exploring the potential of
geothermal energy and its transformative impact on small communities. The NM RIG is excited to host Emilie Gentry from Teverra. Teverra is a company with a vision to turn clean energy into reality. Emilie will share their work in Geothermal District Heating. Learn about their current project in Rico, CO, and how the community is harnessing a local geothermal resource to provide long term sustainable solutions for their energy needs. Attendees will learn about the local geology, community policy and permitting challenges, and how the community of Rico came together to leverage geothermal as a long term solution. Attendees will learn how Rico, CO can be a model for small communities across New Mexico to build more resilient, sustainable energy systems.

2025 Alaska RIG presents "Advances in EGS: What's in it for Alaska"

Description
John Eichelberger, the Geothermal Program Manager of Alaska Division of Geological and Geophysical Surveys
Hot Dry Rock (HDR) geothermal technology began at Los Alamos National Laboratory in the 1970s, aiming to create artificial geothermal reservoirs—now called Enhanced Geothermal Systems (EGS)—where natural ones didn’t exist. The concept proved that circulating water through fractures in hot granite could generate energy, but drilling costs outweighed returns at the time. Advances in drilling and fracturing from the oil and gas industry may now make EGS viable, with promising projects underway in Utah. If successful, this could open vast geothermal potential in Alaska, especially in magma-rich regions, though key performance questions remain.

Introduction to Webinar presentation

Hot Dry Rock (HDR) was born at Los Alamos National Laboratories (LANL), Los Alamos, New Mexico in the 70s. Succeed would have greatly expanded opportunities for geothermal energy through development of artificial geothermal reservoirs [now called Enhanced or Engineered Geothermal Systems (EGS)] where natural ones did not exist. I was very lucky to witness its early days as a volcanologist – essentially the study of very hot rock – in my first job there after graduate school. The project invented and proved the concept of circulating water through artificial fractures in hot granite between two boreholes to extract energy. The site is on the rim of Valles Caldera, one of three giant Late Pleistocene Calderas in the United States. A great deal was learned about the mechanics of fracturing rock, about being able to map fracturing in 4D with seismic arrays, and about directional drilling. But the drilling cost more than the energy was worth. Meanwhile, the oil and gas industry, aided by developments in the DOE laboratories, greatly advanced both drilling technology and hydraulic fracturing (“fracking”), to the extent that the US became a net exporter of natural gas. Could Enhanced Geothermal Systems (EGS), the reincarnation of HDR, now succeed where its predecessor failed? After years of preparation by two exciting projects in the Mineral Mountains of Utah, we will soon learn the answer. According to all the news reports, the answer is a big yes, but we do not know how fast the thermal output will decline or how much water will leak away. Meanwhile, most geothermalists have forgotten what was obvious at Los Alamos and should be obvious in the Mineral Mountains: that the heat is coming from nearby magma. If the most optimistic of claims for EGS are fulfilled, much of Alaska will be fair game. If not, Alaska still has great geothermal potential because we have a lot of magma (some assembly required). The jury is still out, but geothermal in Alaska should have a bright future.

CO RIG Hosts 2nd Annual Field Trip

Description
Join us for our second Geothermal Rising Colorado RIG geothermal field trip through Colorado's Front Range, as we unravel the geological features that set up potential geothermal resources deep in the Denver Basin. This field trip delves into the heart of the earth's thermal energy, focusing on the Lyons Formation and Pre-Cambrian basement outcrops along the Front Range for their geothermal energy potential. Additionally, we will spend some time at the start of the trip learning about ground source heat pumps (GSHPs) by touring the newly constructed East Classroom building at Colorado School of Mines and the GSHP system that was engineered to heat and cool this building.
