Geothermal power is a renewable energy source that uses the Earth's internal heat to produce electricity and heat water. One-hundred and fifty megawatts is roughly enough electricity to power 38,000 homes.

The document addresses the need for enforceable safety provisions for geothermal district ambient temperature loop systems.

The awardees will focus on early-stage R&D projects exploring innovative technologies for drilling geothermal wells that show the ability to reduce non-drilling time, improve rates of penetration, and identify methods to accelerate the transfer of geothermal drilling and related technologies from the laboratory to the marketplace. 

The possibility of producing shale gas in some European countries has triggered a very heated debate about the environmental and social impacts of the technique used to extract gas from shale rocks (today only in the US and Canada); this technique is widely known as hydraulic fracturing or fracking.

As the thousands of people in the geothermal energy industry wrap up an exciting and challenging year, they are united by some recurring themes. Investigative geologists, problem-solving engineers, and pioneering international business leaders are some of the players who worked this year to bring together the heat of the Earth with the cities, customers, and other industries that need its unique environmental and economic benefits.

Iceland is moving closer to plugging European homes into the volcanic island nation’s geothermal and hydropower reserves via what would be the world’s longest power cable, according to the country’s largest energy producer.

Scientists have reviewed the potential for worldwide development of geothermal energy systems in old, unused mines. The technology is proven in many sites and could therefore help increase the share of renewable energy sources in the energy mix, offering sustainability and job creation, which may make mining operations more appealing to investors, communities and policymakers.

A new screening tool to assess the potential seismic risks (earthquake activity) from deep geothermal energy projects has been outlined in a recent study. The tool provides categories of seismicity risk for projects, which are dependent on factors including geological aspects, as well as social concern and location in relation to urban areas.

Shafts that haven't been closed could be transformed into geothermal boilers to produce heat and hot water for nearby communities.

Thousands of drilling rigs are idle and roustabouts are being laid off. Why not put them to work drilling for renewable energy?

A system comprises an injection well for accessing a reservoir containing a native fluid comprising a hydrocarbon. The reservoir is located below one or more caprocks, is at a first temperature, and is accessible without using large-scale hydrofracturing. The system further includes a production well in fluid communication with the reservoir, a supply apparatus configured to feed a non-water based working fluid at a second temperature that is lower than the first temperature through the injection well to the reservoir. The working fluid mixes with the native fluid to form a production fluid comprising at least a portion of the working fluid and at least a portion of the hydrocarbon at a third temperature that is higher than the second temperature. An energy recovery apparatus in fluid communication with the productions well converts energy contained in the production fluid to electricity, heat, or combinations thereof.

Reykjavik Geothermal, a power developer backed by hedge fund billionaire Paul Tudor Jones II, is about to kick off a $4.4 billion project to bring geothermal energy to Ethiopia.

The next generation of geothermal plants will unlock more of Earth's bountiful, underground energy and could allow the technology to finally fulfil its promise

Geothermal power has a promising future, but so far it has lagged behind most of its other renewable energy cousins, especially wind and solar.
