Geothermal Mining

Geothermal mining is Bitcoin mining powered by electricity derived from the Earth's internal heat. Geothermal power plants drill wells deep into the crust to tap hot water and steam, then use that steam to spin turbines and generate electricity. Because the heat source is continuous and weather-independent, geothermal provides steady baseload power—unlike solar or wind, it does not stop at night or in calm conditions.

The El Salvador example

The best-known geothermal mining operation runs at the Tecapa volcano in El Salvador, where a state-run facility generates around 150 megawatts and diverts a slice of it to a Bitcoin mine of roughly 300 machines. The country sits on the Pacific Ring of Fire with more than 20 active volcanoes, giving it abundant geothermal potential. Over about three years the state operation has mined hundreds of bitcoin, framed publicly as a way to monetize a national natural resource.

Why geothermal suits mining

Geothermal plants are often built where energy demand is thin—remote volcanic or tectonic regions far from large population centers. That can leave generation capacity stranded with no local buyer. A Bitcoin mine acts as a flexible, co-located load that turns otherwise-underused clean power into revenue, much as miners do for surplus hydro or curtailed renewables. The trade-off is high upfront drilling cost and geographic constraint: you can only mine where the heat is.
