Alaska Leases Geothermal Rich Augustine Volcano

Alaska’s Ambitious Step into Geothermal Energy: Augustine Volcano Lease Sale in Focus

By:Robert Buluma

Nestled in the heart of southern Cook Inlet, the imposing Augustine Volcano stands as both a challenge and an opportunity. Rising 4,133 feet, this cone-shaped volcanic island has piqued the interest of geothermal enthusiasts, policymakers, and energy companies alike. In an exciting development, Alaska’s Division of Oil and Gas is preparing for a geothermal lease sale on Augustine’s north side—a bold move to harness the earth’s untapped power.

This initiative, sparked by interest from three companies eager to explore geothermal resources, could mark a turning point in Alaska's energy landscape. With a best interest finding issued on January 10, 2025, state officials have paved the way for what could become a groundbreaking exploration effort. As spokesperson Sean Clifton hinted, a lease sale announcement may arrive as early as this spring, opening up 55,771 acres of potential energy riches across 24 tracts.

But why Augustine, and why now?  


A Volcanic Energy Frontier

Volcanoes, long regarded as sources of awe and fear, hold immense geothermal energy potential beneath their surfaces. Globally, geothermal projects at volcanic sites, such as Nevada’s long-operating power plant on a volcano’s flank, have demonstrated the viability of such ventures. Alaska, teeming with active volcanoes along the Gulf of Alaska, presents an untapped frontier for this renewable energy source. Augustine joins Mount Spurr and Makushin Volcano as key areas of interest due to their proximity to population centers.  

Despite this potential, the journey to harness geothermal energy from volcanoes is fraught with challenges. Drilling into a volcano, especially one on an isolated island like Augustine, is not for the faint-hearted. The risks, ranging from explosive eruptions and mudslides to tsunamis, demand meticulous planning and innovative technologies. Moreover, environmental stewardship will be paramount, with steps required to protect local fish and wildlife habitats.

The Renewed Geothermal Push

What’s driving this renewed interest in geothermal energy? Part of the answer lies in shifting federal policies. The Inflation Reduction Act of 2022 introduced tax credits for geothermal power plants and technologies, alongside opportunities for loan guarantees. These incentives have revitalized the sector, making geothermal exploration more attractive than ever.  

With US pushing incentives into Geothermal inform of tax reductions

Although Augustine’s potential lease sale operates under Alaska’s long-standing geothermal program, the state’s broader legislative landscape has also evolved. House Bill 50, passed last year, aims to enhance Cook Inlet and Railbelt energy projects, further signaling a statewide commitment to clean energy solutions.

A Cautious Optimism

While the prospects are thrilling, Clifton strikes a note of caution: “The initial interest doesn’t always materialize into bidding. Drilling into a volcano, that’s hard. On an island.” Indeed, history offers sobering lessons. Despite decades of interest, no energy production has materialized from Alaska’s volcanic geothermal sites.  

However, successful examples elsewhere in the state, such as the geothermal-powered operations at Chena Hot Springs and Pilgrim Hot Springs, highlight the possibilities. If the Augustine project overcomes its unique challenges, it could serve as a beacon for future volcanic geothermal ventures.

Looking Ahead

For Alaska, the Augustine lease sale represents more than just an energy project. It’s a bold step toward redefining the state’s energy future, reducing reliance on fossil fuels, and positioning itself as a leader in renewable energy innovation.  

As we await the official announcement this spring, one thing is clear: the eyes of the energy world are on Augustine Volcano. Will this island of fire and ash become Alaska’s next renewable energy powerhouse? Only time—and perhaps some daring exploration—will tell.

Driving the UK Toward Net Zero: Chris Sladen on Geothermal’s Untapped Potential

Alphaxioms, we talked to Chris Sladen about his involvement in geothermal both in the UK, and globally By:  Robert Buluma Chris, please begin by explaining a little about yourself, and why you have a passion for geothermal? I have spent over 45 years involved in energy. Following undergraduate studies in geology at Southampton University, and a PhD in sedimentology at Reading University, I joined the energy sector in Aberdeen in 1980. It was a fascinating era when it seemed like at least one giant oil & gas field was discovered offshore every month; the wealth creation for the UK was gigantic. I got to see so much geology and rocks - my true passion. I moved to China in late 1983; not today’s China, this was over 40 years ago, a country closed for decades and embarking on an open-door policy, in part to bring both investment and technology. I became very interested in energy trends, energy politics, and new geography created by changing politics leading to opportunities for ene...

Unlocking Geothermal Power: Subsurface Secrets of Mount Erciyes Revealed”

Mount Erciyes: A Hidden Geothermal Treasure Beneath Cappadocia By: Robert Buluma Beneath the snow-capped slopes of Mount Erciyes , central Turkey’s highest peak, lies more than just volcanic history  it harbors the promise of geothermal energy . A new study published in the Journal of Volcanology and Geothermal Research has mapped the subsurface of Erciyes using three-dimensional magnetotelluric (MT) imaging , revealing zones of high electrical conductivity that point to heat, fluids, and possible magma bodies deep underground. Cracking the Code Beneath the Mountain Researchers led by S.B. Tank used advanced MT techniques to peer beneath Erciyes and its surroundings. Their results uncovered conductivity anomalies   regions where electricity flows more easily due to the presence of saline fluids, hot water, or partially molten rock . For geothermal experts, these anomalies are gold. They act as subsurface fingerprints of geothermal reservoirs , highlighting where heat ...
