Geothermal

Fervo's "next-generation geothermal" technology has proven itself in testing, becoming the most productive enhanced geothermal plant in history. The company hopes its approach will radically expand access to clean energy, like shale did for oil.

Slovakia's GA Drilling has demonstrated a pair of new technologies it says could unlock geothermal power generation more or less anywhere on the planet. Anchorbit and Plasmabit promise much faster and cheaper drilling into hot rock 10 km underground.

Plans are afoot for a magnificent new open air lagoon in Canada that will be kept at balmy temperatures year-round through a “huge Thermos” heating system underneath to become the largest lagoon of its type in the world.

Quaise's ultra-deep geothermal power plan is one of the most exciting and fascinating green energy projects we've seen, and it's generated some excellent – and terrible – questions from our readers. We gave the company the chance to answer you.

MIT spin-off Quaise says it's going to use hijacked fusion technology to drill the deepest holes in history, unlocking clean, virtually limitless, supercritical geothermal energy that can re-power fossil-fueled power plants all over the world.

BP and Chevron have led a US$40 million investment round for a Canadian startup that claims to have developed a unique way to extract energy from geothermal heat on demand, using an unpowered looping fluid design that's already prototyped in Alberta.

Visitors to Iceland will soon be able to take a dip in a new geothermal lagoon. The under-construction Sky Lagoon will provide amenities like a sauna, bar, and cold water pools – but the big draw with this one is going to be its amazing ocean views.

CERN’s Large Hadron Collider (LHC) has made some groundbreaking discoveries for physics, but it’s hard to tell how exactly that benefits the average Joe/Jill. Now CERN has announced that the LHC will soon divert some of the waste heat from the collider to help heat thousands of nearby homes.

One of the largest natural sources of renewable energy could be right under our feet – literally – with geothermal energy. Now researchers at Tokyo Institute of Technology and Sanoh Industrial have developed a new type of battery cell that can directly convert heat energy into electricity.

Many of us will know what bubbling lakes of lava within volcanoes look like. After all, we've seen them our entire lives in movies and on TV. But that doesn't mean they're common. In fact, only seven lava lakes have been found so far, until now.

​After opening the world’s first commercial Direct Air Capture (DAC) plant designed to pull CO2 out of the air, Swiss company Climeworks is now joining forces with a geothermal power plant in Iceland to create the world’s first “negative emission” power plant.

Google’s parent company, Alphabet, has now spawned Dandelion, a new startup that aims to tap into geothermal energy. The company’s signature technology is a geothermal heating and cooling system that pumps heat from the ground into the home in winter, or out of it during summer.
