National Labs Push Geothermal Research

DOE-backed alliance aims to cut risk and cost in engineered geothermal systems

24 Feb 2026

A group of US national laboratories and universities is stepping up efforts to bring engineered geothermal energy closer to commercial use, as policymakers look for reliable low-carbon power sources.

The initiative, known as EGS Collab and backed by the US Department of Energy, brings together Lawrence Berkeley National Laboratory, Pacific Northwest National Laboratory and academic partners including Stanford University. Its aim is to reduce the technical and financial uncertainty that has limited large-scale deployment of Enhanced Geothermal Systems (EGS).

Unlike conventional geothermal projects, which rely on naturally occurring hot water reservoirs, EGS involves creating underground pathways by fracturing hot rock deep below the surface. The resource is considered widely available and potentially scalable. However, developers face persistent questions over how fractures spread, how reservoirs perform over time and how to manage the risk of induced seismicity.

Researchers involved in the programme have told DOE briefings that better forecasting of subsurface behaviour is essential for commercial expansion. Through controlled underground experiments and advanced modelling, EGS Collab is collecting detailed data to improve understanding of reservoir performance. The work supports field testing at the Frontier Observatory for Research in Geothermal Energy in Utah, the DOE’s main demonstration site for EGS.

Cost remains a central barrier. Drilling and well construction can account for more than half of total project expenditure. Uncertainty below ground increases financial risk and complicates permitting. Improved reservoir characterisation and forecasting tools may help developers and investors better assess project viability and manage risk.

The research comes as utilities seek firm, carbon-free generation to balance intermittent wind and solar power. Federal incentives have increased support for geothermal demonstration projects. Yet large-scale commercialisation remains uncertain, dependent on sustained cost reductions, consistent field results and regulatory approval.

Translating experimental findings into repeatable performance in commercial settings remains a challenge. Concerns over induced seismic activity also continue to shape public and regulatory scrutiny.

Even so, coordinated federal research efforts are strengthening the scientific base of engineered geothermal systems, as policymakers weigh their role in a broader clean energy mix.
