Hot Rock Power
An enhanced geothermal system (EGS) generates geothermal electricity without natural convective hydrothermal resources. Traditionally, geothermal power systems operated only where naturally occurring heat, water, and rock permeability are sufficient to allow energy extraction. However, most geothermal energy within reach of conventional techniques is in dry and impermeable rock. EGS technologies expand the availability of geothermal resources through stimulation methods, such as 'hydraulic stimulation'. Overview In many rock formations natural cracks and pores do not allow water to flow at economic rates. Permeability can be enhanced by hydro-shearing, pumping high-pressure water down an injection well into naturally-fractured rock. The injection increases the fluid pressure in the rock, triggering shear events that expand pre-existing cracks and enhance the site's permeability. As long as the injection pressure is maintained, high permeability is not required, nor are hydrauli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

2017 Pohang Earthquake
The 2017 Pohang earthquake, measuring magnitude 5.4 on the Richter scale, struck Heunghae, Pohang, South Korea on November 15, 2017, and the hypocenter was 7 km below the surface. It is tied with the 2016 Gyeongju earthquake as the country's strongest earthquake in modern history since seismological observations started in Korea in 1978, and the most destructive ever recorded with "an estimated 300 billion won (US$290 million) in damage.". It also recorded a VII intensity on the Modified Mercalli intensity scale, making it the second largest earthquake in recorded history in Korea. Tectonic setting Although the Korean Peninsula is part of the Eurasian plate, until the early Tertiary era (about 30 million years ago), it was made up of continental magmatic arcs along a plate border. With the coetaneous formation of smaller-scale basins, such as the Pohang, and the opening of the East Sea (or Japan Sea) as a back-arc basin in the early to middle Tertiary (~30 to 15 million ye ...

Induced Seismicity In Basel
Induced seismicity in Basel led to suspension of its hot dry rock enhanced geothermal systems project. A seismic-hazard evaluation was then conducted, resulting in the cancellation of the project in December 2009. Basel Basel ( ; ), also known as Basle ( ), ; ; ; . is a city in northwestern Switzerland on the river Rhine (at the transition from the High Rhine, High to the Upper Rhine). Basel is Switzerland's List of cities in Switzerland, third-most-populo ..., Switzerland sits atop a historically active fault and most of the city was destroyed in a magnitude 6.5 earthquake in 1356. But the Basel project, although it had established an operational approach for addressing induced earthquakes, had not performed a thorough seismic risk assessment before starting geothermal stimulation. Seismic events in Basel reached the trip point of Richter Magnitude 2.9 six days after the main stimulation was started on December 2, despite precautionary reduction of the injection rate ...

Alsace
Alsace (, ; ) is a cultural region and a territorial collectivity in the Grand Est administrative region of northeastern France, on the west bank of the upper Rhine, next to Germany and Switzerland. In January 2021, it had a population of 1,919,745. Alsatian culture is characterized by a blend of German and French influences. Until 1871, Alsace included the area now known as the Territoire de Belfort, which formed its southernmost part. From 1982 to 2016, Alsace was the smallest administrative in metropolitan France, consisting of the Bas-Rhin and Haut-Rhin Departments of France, departments. Territorial reform passed by the French Parliament in 2014 resulted in the merger of the Alsace administrative region with Champagne-Ardenne and Lorraine to form Grand Est. On 1 January 2021, the departments of Bas-Rhin and Haut-Rhin merged into the new European Collectivity of Alsace but remained part of the region Grand Est.

Soultz-sous-Forêts
Soultz-sous-Forêts (; ) is a commune in the Bas-Rhin department in Grand Est in north-eastern France. The French revolution In December 1788 Mary de Bode who had been born in England and her German born husband Baron de Bode arrived in Soultz-sous-Forêts. The Baron was given the fiefdom of Soultz-sous-Forêts by the Archbishop of Cologne ( Maximilian Franz of Austria). Mary described Soultz-sous-Forêts as a land "flowing with corn and oil and wine." They hoped that the French Revolution would not affect them, but at the end of 1794 the Baron and Baroness de Bode moved out of the town, before they mistakenly returned. They were lucky to make a quick escape over the mountains, but they left all their riches and five of their children behind them. Clement, one of their sons, and his son tried unsuccessfully, for seventy years, to regain the rights and riches they lost in the 1790s. In June 1854, the case of the de Bode family was debated in the British Houses of Parliament ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United Downs Deep Geothermal Power
United Downs Deep Geothermal Power is the United Kingdom's first geothermal electricity project. It is situated near Redruth in Cornwall, England. It is owned and operated by Geothermal Engineering (GEL), a private UK company. The drilling site is on the United Downs industrial estate, chosen for its geology, existing grid connection, proximity to access roads and limited impact on local communities.

Rosemanowes Quarry
Rosemanowes Quarry, near Penryn, Cornwall, England, was a granite quarry and the site of an early experiment in extracting geothermal energy from the earth using hot dry rock (HDR) technology. Quarry In the nineteenth century the quarry provided stone for building projects in Britain and abroad as well as for the Ponsanooth viaduct near Penryn and the Carnon Valley viaduct between Truro and Falmouth. Geothermal energy research project The site was chosen as the research site because the granite in the area has the highest heat flow in England (120 milliwatts per square metre). The trials began in 1977 in the wake of the 1973 oil crisis and an earlier trial in the United States at Fenton Hill. The trials at Rosemanowes concluded in 1980, although studies continued until 1991. Funding for the initial project was provided by the Department of Energy (now the Department of Trade and Industry) and by the European Commission.

Map Of 64 EGS Sites Around The World
A map is a symbolic depiction of interrelationships, commonly spatial, between things within a space. A map may be annotated with text and graphics. Like any graphic, a map may be fixed to paper or other durable media, or may be displayed on a transitory medium such as a computer screen. Some maps change interactively. Although maps are commonly used to depict geographic elements, they may represent any space, real or fictional. The subject being mapped may be two-dimensional such as Earth's surface, three-dimensional such as Earth's interior, or from an abstract space of any dimension. Maps of geographic territory have a very long tradition and have existed from ancient times. The word "map" comes from the , wherein ''mappa'' meant 'napkin' or 'cloth' and ''mundi'' 'of the world'. Thus, "map" became a shortened term referring to a flat representation of Earth's surface. History Maps have been one of the most important human inventions for millennia, allowing humans t ...
