Webinar Title: Campus Heat, Regional Reach: Geothermal and TENs in Action

Webinar Description: Join the Geothermal Rising Pacific Northwest Regional Interest Group (PNW RIG) for a compelling webinar showcasing innovative geothermal and district energy systems shaping the future of sustainable infrastructure.

Delano Palmer of Central Washington University will present a micro-case study on CWU’s geothermal heating and cooling project, offering a deep dive into the technical design, implementation, and performance of campus-scale geothermal systems.

Nicholas Fry of Jacobs will follow with a high-level overview of Thermal Energy Networks (TENs), focusing on district and campus energy systems and their role in regional decarbonization strategies.

As a supporting theme, both presenters will touch on workforce development—exploring how students and professionals can engage with the growing geothermal and TENs sectors. Delano will share insights on preparing university-aged students for careers in energy, while Nicholas will highlight relevant skills, certifications, and career pathways in the TENs space.

 This session is ideal for energy professionals, educators, students, and anyone interested in the technical and workforce dimensions of geothermal and district energy systems.

We are organizing a focused strategy session for the Hawaii Regional Interest Group (RIG) to help shape our direction for the coming year. This session is designed to be highly collaborative and action-oriented. Because of the nature of the discussion, attendance will be limited to individuals who are currently engaged in the Hawaii RIG or have demonstrated familiarity with Hawaii-based geothermal issues, priorities, or partnerships.

To ensure we stay productive and that all participants can contribute meaningfully, we’ve implemented a pre-approval registration process. We kindly ask interested attendees to request access using the link below. This allows us to maintain a manageable group size while honoring the intent of a strategic, working session.

Why this matters:
This meeting will focus on building local momentum, identifying challenges, and advancing geothermal efforts specific to Hawaii. The discussion will assume a foundational understanding of Hawaii’s regulatory, technical, and community landscape. It’s important to keep the group targeted so that all participants are aligned in focus and purpose.

If you're currently involved or have worked with Hawaii geothermal stakeholders—or are deeply interested in becoming more active in the RIG—we welcome
your request to attend.

We will welcome a guest speaker or two in our agenda:
- Updates on educational outreach efforts and recent media coverage of the Hawai'i Fossil Fuels Report and other geothermal topics
- News from Nicole and HGGRC on local scientific projects on Maui and Hawai'i Island
- A fascinating trip report from Nicole's visit to the birthplace of geothermal power production in Italy

Also, Geothermal Rising has discontinued Google Groups. Please log in to see our event calendar, a discussion area, and other resources.

IMPORTANT: as part of our new platform, you will need to register before the call. Please visit this link:

Mahalo, and hope to see you in two weeks!

Since late 2023, Teverra has explored Fort Wainwright, Alaska, as part of the Defense Innovation Unit (DIU) Geothermal Commercial Solutions Opening. This Geothermal Prototype Initiative included existing data collation, new data collection, and stratigraphic test well planning. In 2023, existing data were collated, in summer 2024, new data were collected and integrated into a 3D geological model, and in 2025, using the completed 3D geologic model, a stratigraphic test well site selection and well design was completed. To our knowledge, this is the first geothermal exploration efforts taking place within the general AOI, and as such, experienced several unexpected challenges. This presentation will give a summary of the work to date,  including showing data collection results and current status of the initiative.

There is a minimum space allotment - register early to confirm you place.
There is a $30 registration fee that will help the Colorado RIG with costs associated with this Field Trip.

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.

Our first field stop in Morrison, Colorado will investigate the Lyons Formation to provide insights into its depositional history, lithology, mineralogy, and thermal conductivity, which are crucial factors for assessing its suitability for geothermal energy as a hot sedimentary aquifer (HSA). Additionally, we will discuss a core-based study in hydrothermal alterations within the Lyons Formation beneath Wattenberg Field, offering valuable clues to the geothermal reservoirs that lie deep in the basin. Venturing into the realm of the Pre-Cambrian basement, participants will visit outcrops in Genesee, Colorado at the second field stop to understand the complex nature of the igneous and metamorphic rocks that have been structurally deformed, uplifted, and exposed here, representing potential enhanced geothermal systems (EGS) targets beneath the Denver Basin. These outcrops and formations are exceptionally important because they are also associated with ongoing geothermal exploration projects deep within the Denver Basin.
