Dynamic simulation and 2D multiple scales and multiple sources within basin geothermal field
In order to accurately describe the geothermal field within a basin, it is necessary to divide it into the normal geothermal field and additional geothermal field. For the accuracy by describing of the additional geothermal field, grids need to be increased. Traditional unequal interval difference method can be used to solve this problem, which has to increase grids within the unnecessary area, ...

A BME solution of the stochastic three-dimensional Laplace equation representing a geothermal field subject to site-specific information
This work develops a model of the geothermal field in the Nea Kessani region (Greece) by means of the Bayesian maximum entropy (BME) method, which describes the temperature variations across space in the underground geological formations. The geothermal field is formed by a thermal reservoir consisting of arcosic sandstones. The temperature distribution vs depth was first investigated by the ...

Evaluation of utilisation opportunities of geothermal energy in the Kavala region, Greece, using exergy analysis
Greece has a lot of geothermal energy fields. Due to legal inefficiencies, the exploitation of this renewable energy source remains at very low levels. In this work, the operation of a cogeneration (hot water and electricity) geothermal plant that could be built in Eratino, Greece, is analysed. The research on the development of a low enthalpy geothermal field is investigated as a very essential ...

New Head Office and Lab Building, Riedering, Germany - Case study
The company EndoLab - a test lab or medical implants - moved its headquarters from Thansau to Riedering near Rosenheim and built a new office and laboratory building for this new location. The task in the first planning phase was the development of a location-specific energy concept as well as climate concepts adapted to the building uses. A number of main uses are defined within the building: ...

Boron pollution due to geothermal wastewater discharge into the Buyuk Menderes river, Turkey
Kizildere, which is the only commercial geothermal power plant in Turkey and located in Buyuk Menderes Graben in south-west Turkey, discharges annually 6 million tonnes of wastewater into the Buyuk Menderes river, creating environmental pollution. Currently, the wastewater, which includes up to 24 mg/l boron, is discharged into the river at a rate of 750–1500 tonnes per hour. The temperature of ...

Projects Thermoelectric Generators in a Geothermal Field - Case Study
This is an R&D project which will build and test a new field-scale thermoelectric generator (TEG) at our Bottle Rock Power geothermal facility near Cobb, California. TEGs produce electrical energy when a strong enough temperature difference exists across the generator (a phenomenon known as the Seebeck effect). This will be the first TEG developed specifically to generate electricity from a ...

Promega Administration and Logistics Center, Walldorf, Germany - Case study
The building essentially consists of two parts. The logistics area houses deep-freeze rooms and cabinets, storage areas and technical equipment for goods packaging and dispatch as well as the production area of the subsidiary Terso. The administration area contains a conference area, a workshop, a canteen with staff kitchen and a fitness area in addition to the office space. The areas are grouped ...

DYGEO: boosting support for geothermals to promote the use of this green energy
In 2018, ADEME and BRGM decided to focus on increasing the visibility of geothermal energy. First of all, this involves uniting the organisations that are promoting geothermal energy around an “advocacy campaign” for surface geothermal energy and then also of increasing the visibility of geothermal energy on the Internet. The need With the Multi-Year Energy Plan predicting that ...

Case Study - Aluto Langano Power Plant Rehabilitation
Aluto Langano, Ethiopia – 2007 The Aluto Langano Geothermal Pilot Plant (ALGPP) is located on the Aluto volcanic complex of the Ethiopian Rift valley, close to the eastern escarpment between Lake Langano and Lake Ziway, some 200 km southeast of Addis Ababa. The Aluto volcanic complex is a young acidic system consisting of domes, lava, and pyroclastic interbeds. The geothermal field was ...

Personal Account: Stanford Geothermal Workshop
AltaRock Energy’s Matt Uddenberg accompanied a group of staff to this year’s Stanford Geothermal Conference, where AltaRock’s Susan Petty and Trenton Cladouhos gave a presentation on the Newberry EGS Demonstration. This was Matt’s first experience with the workshop, so we asked him to share his experience. Why I Went I was fortunate enough to have my first experience ...

As Global Demand for Electricity Grows, Geothermal Energy Heats Up
January 9, 2017 — At 2:46 p.m. local time on Friday, March 11, 2011, Japan was rocked by the largest earthquake ever to strike its shores. The 9.1 magnitude quake triggered a devastating tsunami that killed more than 15,000 people. It also took out the back-up emergency generators that cooled the reactors at the Fukushima Daiichi nuclear power plant complex, causing a series of catastrophic ...

Strada Global: Why we only bill what we drill
‘As we move toward clean energy, one of the guiding principles going forward is a diversity of renewables’. David Hochschild, California Energy Commission. We couldn’t agree more. Which is why here at Strada Global, we are focused on challenging the status quo of historic geothermal mindsets with new, innovative drilling technology and approaches that make geothermal power ...

Artificial geothermal energy potential of steam-flooded heavy oil reservoirs
This paper explores the concept of harnessing geothermal energy from heavy oil fields that have undergone steam flooding and so accumulated substantial heat from steam injection. Once the steam flooding process reaches economic cut-off resulting from high water cut and/or high steam-to-oil ratio, the reservoir would be abandoned, leaving behind stored energy in the form of heat. From this point, ...

Projects Davenport Newberry Holdings, LLC. - Case Study
AltaRock Energy, Inc. actively manages over 40,000 acres of geothermal leases on the western flank of Newberry Volcano in central Oregon. The leases, held by Davenport Newberry Holdings, LLC. (DNH) and administered by the US Bureau of Land Management, represents a unique opportunity to test and develop Enhanced Geothermal System (EGS) technologies in the field. In partnership with the US ...

Projects Umatilla Indian Reservation Geothermal Resource Study - Case Study
This is an exciting new project to expand understanding of the natural resources of the Umatilla Indian Reservation (UIR) and move the Confederated Tribes of the Umatilla Indian Reservation (CTUIR) one step closer to energy independence. AltaRock is working with HotRock Energy Research Organization (HERO), the CTUIR, and the United States Geologic Survey (USGS) to look at the geothermal resource ...
