Ignis Energy secures geothermal sites in Nevada and California
Ignis Energy is set to conduct detailed exploration work at geothermal sites in Nevada and California, further expanding an impressive international portfolio.
Geothermal startup Ignis Energy has announced its entry into the geothermal markets of both Nevada and California. With this, the company’s portfolio has expanded into the continental United States, complementing their presence in Alaska, Türkiye, and Italy.
Nevada Basalt
In Nevada the key area of interest for Ignis Energy is a basalt intrusion within the company’s lease, which signals volcanic activity and indicates elevated geothermal gradients. The region’s proximity to the range front suggests likely fracturing, a positive sign for geothermal productivity. Additionally, the presence of metamorphic core complexes at one of the project sites supports the potential for elevated temperatures and permeability—critical components for a successful geothermal system.
Ignis Energy has indicated initial plans to conduct comprehensive surveys in the prospect area. Methods will include such as Magnetotelluric and gravity surveys, along with shallow temperature measurements and seismic assessments to accurately evaluate subsurface potential.
The company aims to tap into the vast conventional geothermal resources found across Nevada’s Basin and Range region while remaining open to testing new technologies as they reach commercial maturity. This comprehensive approach to geothermal development emphasizes sustainability and innovation.
Clear Lake Volcanic Field
Ignis Energy has also secured a significant lease position in in Northern California’s Clear Lake Volcanic Field (CLVF). This is a prominent location for geothermal energy, already with two proven geothermal sites, including The Geysers, the largest developed geothermal field in the world. Preliminary data suggests that the site hosts a high-temperature, liquid-dominated geothermal resource, with a potential capacity of 60-120 MW.
The CLVF is a region is marked by an unusually high heat flow, making it a prime target for geothermal development. Typical geothermal gradients in the area range from 4-6 °F per 100 feet, but certain structural zones experience significantly higher temperatures, with gradients reaching 10-30°F per 100 feet—ideal conditions for geothermal energy production.
Surface indicators such as gas seepages, thermal water, and hydrothermal mineral deposits, along with past temperature readings as high as 525 °F (274 °C) in an offset well, further support the site’s geothermal potential. Future exploration efforts, including advanced geophysical surveys and additional drilling, will help confirm the resource and move toward development. MT and gravity surveys are scheduled in the area for Q1 2025.
