Germany: Taufkirchen Geothermal Power Plant Begins Electricity Generation

Daldrup & Söhne AG: Successful test operation and stable power production in Taufkirchen geothermal power plant (News Release)

The geothermal power plant of GeoEnergie Taufkirchen GmbH & Co. KG, a subsidiary of the drilling technology and geothermal specialist Daldrup & Söhne AG, has started electricity production in Taufkirchen.

The first feed-in was preceded by successfully completed system tests of the components of the power generation plant in recent days. This means that, for the first time and in parallel to the district heating supplied to the communities of Taufkirchen and Oberhaching, environmentally friendly electricity generated at the power plant will now be fed into the public grid.

With the weather-related decline in district heating production, the power production of the plant is being ramped up further. A further heat exchanger will be connected in the second half of 2018. Thus, from today's perspective electricity production will then gradually switch to full load operation. For the further planning of the 2018 financial year, the management board assumes that corresponding feed-in revenues can be generated from power generation.

Canada: Abandoned New Brunswick Mine to Provide Geothermal Heating and Cooling for Community

Geothermal heating a good use of flooded Picadilly mine, report says (CBC)

The core idea behind geothermal heating involves extracting the heat of the water deep inside the mine.

More than two years after Sussex was rocked by the closure of the Picadilly mine, the town is getting some good news about the mine —  it can likely be used for geothermal heating.

The mine in Penobsquis, near Sussex, was allowed to flood after operations ended there in 2016, and 430 jobs were lost.

Geothermal heating involves extracting the heat of the water from inside the mine. A company could then use that energy cheaply, making Sussex more attractive for new industry.

Scott Hatcher, chief administrative officer for the town said it appears from the feasibility study that the model that would most benefit the town is something called an "open loop" geothermal system, which would involve directly extracting the hot water, drawn through a pipe. "Once used, it would be injected back into the mine," Hatcher said.

USA, Wyoming: New Research Strongly Supports a Deep Origin for the Yellowstone Hotspot

Lower-mantle plume beneath the Yellowstone hotspot revealed by core waves (Nature Geoscience)

The Yellowstone hotspot, located in North America, is an intraplate source of magmatism the cause of which is hotly debated. Some argue that a deep mantle plume sourced at the base of the mantle supplies the heat beneath Yellowstone, whereas others claim shallower subduction or lithospheric-related processes can explain the anomalous magmatism.

Here we present a shear wave tomography model for the deep mantle beneath the western United States that was made using the travel times of core waves recorded by the dense USArray seismic network.

The model reveals a single narrow, cylindrically shaped slow anomaly, approximately 350 km in diameter that we interpret as a whole-mantle plume. The anomaly is tilted to the north-east and extends from the core–mantle boundary to the surficial position of the Yellowstone hotspot. The structure gradually decreases in strength from the deepest mantle towards the surface and if it is purely a thermal anomaly this implies an initial excess temperature of 650 to 850 °C.

Our results strongly support a deep origin for the Yellowstone hotspot, and also provide evidence for the existence of thin thermal mantle plumes that are currently beyond the resolution of global tomography models.

USA: Congress Requests Increased Spending for Department of Energy

Congress' spending deal rejects Trump's proposed EPA, energy cuts (Washington Examiner)

Congress on Wednesday night released a fiscal 2018 spending bill that rejects Trump administration efforts to reduce funding for the Environmental Protection Agency and Energy Department.

After President Trump threatened to make massive cuts to the EPA budget, Congress decided to keep funding levels the same from fiscal 2017, at $8.1 billion.

The Energy Department, meanwhile, would receive $34.5 billion in the massive spending deal, a $3.77 billion increase over fiscal 2017.

That includes $2.32 billion for the agency’s energy efficiency and renewable energy division, a 15 percent increase. Trump, who has promoted expanded fossil fuel development, had sought to cut funding for that division.

PNNL and Oregon State University researchers will explore the potential of volcanic heat for energy
Two geophysicists noted for their work to harness the underground heat from volcanoes to produce electricity began joint appointments at each other’s institutions in January. The dual appointments enable GRC Member Alain Bonneville, Pacific Northwest National Laboratory (PNNL), and Adam Schultz, Oregon State University, to increase their collaboration on current and proposed projects, including traveling to each other’s institutions to share their insights and mentor students and interns.

A particular focus for the two colleagues is finding the most effective ways to extract underground heat from the Newberry Volcano in central Oregon. Newberry is one of the largest geothermal heat reservoirs in the western United States. A public-private consortium, Newberry Geothermal Energy (NEWGEN), is developing a research observatory on geothermal energy at the volcano, drilling high-temperature wells. The project aims to test more efficient, less costly, and innovative ways to extract underground heat where conventional geothermal power generation isn’t possible. Bonneville, Schultz, and their colleagues have been developing innovative methods that use electromagnetic instrumentation, sensitive gravity meters, measurements of ground deformation, and new computer-aided modeling methods to look under the volcano’s surface.

Canada: Alberta Town Repurposing Oil & Gas Wells for Geothermal Energy

Why a Small Alberta Oil and Gas Town is Pursuing Geothermal Power (DeSmog Canada)

(Google Maps)
Like many towns across Alberta, the landscape around Hinton is a pincushion of oil wells. At the bottom of some of the deeper wells, temperatures can reach upwards of 120 degrees Celsius, and that geothermal heat could be about to spur the town on to its next energy windfall.

A plan is underway to pump water up from deep underground, capture the heat it brings to the surface, then re-inject that water into the ground. The captured heat could warm a dozen municipal buildings or even eventually provide electricity.

“That’s attainable, that’s not a huge technical challenge. The question is at what cost,” Jonathan Banks, a research associate in geoscience at the University of Alberta, told DeSmog Canada.

The town recently got $1.2 million in federal and provincial grants to explore the feasibility of the project, known as a Front-End Engineering and Design, or FEED, study. That should be complete by the end of the summer.

“If the FEED study shows that the project is viable…we could start building the system in the fall of 2018,” Banks says, cautioning that there are a number of unknowns, such as an uncertain regulatory process.

A big part of why newly elected town councillor Dewly Nelson thinks the oil-friendly residents should welcome geothermal to town? It all runs on the same infrastructure and knowledge as the oil and gas industry, making it an excellent way to make use of existing oilfields and some of the workers who have been hit by low oil prices.

“If it ever really takes off on a large scale in Canada, it will be because of oil and gas,” he says.

France: Second Well Completed at Cachan Geothermal District Heating Project

Subhorizontal Geothermal Well Architecture - A Proven Concept

A second subhorizontal well successfully completed and tested at Cachan (Paris Basin, France)

The second subhorizontal geothermal well has been completed on the Paris suburban Cachan site for its customer Dalkia (EDF Group).

The well, which will serve as the injection unit of the local Geothermal District Heating doublet, is similar in design to the production well achieved in late December 2017, recorded as a world premiere in geothermal well engineering. It features an open-hole drain, 8"1/2 in diameter and 1,005 m long (against 1,001 m for the first well).

Targeted at a nominal 450 m3/h productive/injective performance, the new doublet managed by a Dalkia/City of Cachan JV (Dalkia operator), will replace two existing, 34 years old, doublets, both cumulating 350 m3/h capacity.
The concept, pioneered by GPC Instrumentation Process (GPC IP), opens attractive perspectives for geothermal development in densely populated areas undergoing moderate to poor (by geothermal standards) reservoir performance.

USA, Washington: Four to Five, 1,600-Foot-Deep Wells to be Drilled in Exploring for Potential Geothermal Power Plants

Washington volcanoes could become power plants (

Could Washington generate electrical power from the Earth’s heat near its volcanoes? That’s what will be explored early this summer as the state Department of Natural Resources (DNR) drills four to five, 1,600-foot-deep wells to begin locating potential geothermal power plants.

“Our hope is that, as you go down into the Earth, these will show an elevated temperature,” said GRC Member Alex Steely, Ph.D. a DNR Geologist who is working on the project. He calls them “temperature gradient” wells.

Several of the wells will be drilled near Baker Lake, off of US 20 south of Mt. Baker. On a generally clear day with little wind, we can be reminded of the steaming vent at the summit reminding us that Baker is a volcano.

The other wells will be drilled about 15 miles northwest of Mount St. Helens. That steam generated by a hot vent that runs miles below the mountain and a reminder that hot rocks and molten magma are not far below the surface whether a volcano is erupting or not.

Science & Technology: Patent Awarded for Method for Producing Power from Two Geothermal Heat Sources

Method and apparatus for producing power from two geothermal heat sources (USPTO)

United States Patent #9,920,749 - Awarded March 20, 2018 to Ormat Technologies, Inc.

A method for producing power from two geothermal heat sources includes: 
  • separating a first geothermal fluid from a first geothermal heat source into geothermal vapor comprising steam and non-condensable gases, and geothermal brine; 
  • supplying the geothermal vapor to a vaporizer; 
  • vaporizing a preheated motive fluid using heat from the geothermal vapor, wherein the heat content in the geothermal vapor exiting the flash tank is only enough to vaporize the preheated motive fluid in the vaporizer; 
  • expanding the vaporized motive fluid in a vapor turbine producing power and expanded vaporized motive fluid; 
  • condensing the expanded vaporized motive fluid to produce condensed motive fluid; and 
  • preheating the condensed motive fluid in a preheater using heat from a second geothermal fluid from a second geothermal heat source having a lower temperature and salinity content that the first geothermal fluid, thereby producing the preheated motive fluid, make-up water and heat-depleted geothermal brine.

Philippines: Bacman Geothermal Power Plant Can Supply less than 1 MW to Customers

Renewable energy for all Filipinos (Manila Bulletin)

Jay Joel L. Soriano, Energy Development Corporation's business unit head for Negros Island

Geothermal energy, as opposed to wind or solar for that matter, is — in our view — the holy grail of RE technologies. It does not depend on the seasons. It does not depend on the time of day. It also does not depend on weather conditions. In other words, properly managed, geothermal can supply clean, uninterrupted power day or night, rain or shine, all year round. And we are blessed to have this energy source in our very own country, a privilege common only to a limited number of countries.

Our Bacman Geothermal Business Unit in Bicol is a part of the Retail Competition and Open Access or ROCA program with the approval of its Retail Electricity Supplier (RES) license. Through Bacman’s RES, we are now able to directly contract with contestable customers with demand below 1MW.

Apart from our preventive maintenance programs to ensure that our power plants are always in good condition, we have invested time and effort to make our facilities typhoon resistant so that they can withstand strong Yolanda-type typhoons, which have become the “new normal” due to climate change. While the upfront investments may seem huge, we believe that the increased reliability and avoidance of future damage will result in lower operational costs in the long run.

St. Lucia: Public Consultations Inform On Geothermal Power Project

No geothermal plant in Saint Lucia! . . . yet (The Star Newspaper)

(Courtesy The Star Newspaper)
Panorama Environmental, Inc. of San Francisco completed an Environmental and Social Impact Assessment (ESIA) for potential geothermal energy exploration in Soufriere in February 2018. The Department of Sustainable Development, within the aforementioned ministry, on Thursday March 15, 2018, hosted its fourth leg of public consultations at the Castries City Hall to explain the findings of the ESIA. Previously, discussions were held in communities in Soufriere which will be directly impacted by any geothermal exploration.

Although consultant Susanne Heim of Panorama Environmental, Inc., along with Aloysiaus Barthelmy who is the local geothermal technical coordinator and Mark Lambrides, a senior energy specialist from World Bank, said that by following World Bank regulations to prevent noise pollution and to sustain human and social rights, as well as keeping international standards of maintaining air and water quality, project coordinators promise a better outcome than the last recorded geothermal exploration phase. It was also constantly mentioned by Barthelmy that the last project was handled “by the British” as opposed to the World Bank this time around.

Algeria: Geothermal Heat Helps Grow Zucchinis in the Desert

First batch of zucchinis from the Touggourt geothermal complex (horti daily)

The first batch of “Gloria" zucchinis, out of the geothermal complex of Touggourt, destined for export, left the port of Oran yesterday, towards Europe.

According to Mr. Taha Derbal, General Director of the National Office of Irrigation and Drainage (ONID) this is the first vegetable produced by the pilot mega-complex of ONID, using geothermal energy in agricultural production. Located in Touggourt, in the province of Ouargla, this complex was built by ONID, in cooperation with the Spanish company Alcantara.

This complex, the first of its kind in Algeria, uses the heat produced by deep drilling for agricultural production; an optimal yield with highly added value. This technique makes it possible to obtain the ideal conditions for the production of early vegetables.

Switzerland: Overview of European Geothermal Phd Days Conference

European Geothermal Phd Day 2018 in Zurich (Blog Post)

By Martin Bloemendal, KWR Watercycle Research Institute

Every year Phd students working on geothermal energy gather to have a short informal conference. This year the ETH in Zurich is the host of the 9th edition. With about 80 participants the conference attracts a stable number of researchers from countries all over Europe and beyond. With 5 people from Delft we were one of main contributing Universities. 

Presentations and posters cover a wide range of topics regarding geothermal energy. From the high enthalpy systems for power production all the way to the Ground source heat pumps and from technical work on simulation and field studies up to governance and management studies. Traditionally the conference is closed with a field trip; to a geothermal power plant.

Some general views on key developments that were presented:
  • New drilling methods. Mankind has always used rotary drilling methods. With the trend towards more and deeper boreholes in more solid rocks, the demand for contactless drilling increases. Promising developments were shown on sonic, laser and waterjet methods.
  • New concepts combining CO2 storage in geothermal reservoirs and recovery for power production
  • New (composite) materials and monitoring methods to ensure well integrity.

In March 2017, Green Energy Geothermal (GEG), headquartered in London, UK, was awarded a contract to design, manufacture and supply a replacement back-pressure turbine and generator for the Bjarnarflag geothermal power plant of Icelandic national power company Landsvirkjun in Iceland. The plant has been in operation since 1969 and is now being updated.

While the old plant has seen a decrease in production, it has been a reliable and important source of power for the Myvatn region in the North of Iceland.

Constructi­on work is now und­erway, with sufficient arrangements to make sure there is no in­ter­f­erence with rela­ted acti­vities in the area, which particularly concerns the operati­on of the local heating plant and the supp­ly of water to the geothermal spa operation at Myvatn.

Germany: Heat from Bavarian Geothermal Power Plant Boosts Tomato Production

Acreage of Strabena tomato doubled (FreshPlaza)

Through the use of geothermal energy, vegetable producer Steiner has been distinguishing itself for several years with its sustainable production, high product quality and exclusive supply to the regional Rewe branches. Despite the excellent position on the market, continuous development is the main focus of the Bavarian producer. Four years after the opening of the first geothermal-heated greenhouse area of 11.4 hectares, the greenhouse complex now consists of more than 20 hectares.

The idea of sustainable, regional vegetable cultivation was implemented in 2014 in Kirchweidach in Upper Bavaria on 11.4 hectares under glass. Since then, the family-owned Steiner company has been producing tomatoes, peppers and strawberries - with geothermal energy and photovoltaics, without fossil fuels. The high number of sunshine hours in the Chiemgau, the unique proximity to the local geothermal plant, as well as the many years of experience of this family of growers are the pillars of successful production.

section of the Jubilee Pool.
Drilling has started at Jubilee Pool, Penzance, Cornwall to make a geothermal well which will draw up water that has been heated deep underground. The heat will then be transferred to water in adjacent pipes which carry water to the pool.

Referring to Iceland's geothermal spa, pool user Jenna Fisher said: "Penzance is going to get its own Blue Lagoon!"

Engineers are drilling down to 1.4 km (0.8 miles) below the surface where temperatures reach up to about 35C (95F).

An expansion underway at the McGinness Hills Geothermal Facility near Austin will make the Ormat Technologies Inc. complex the largest geothermal power generating facility in the state, and the largest located on Bureau of Land Management property.

The Bureau of Land Management, Mount Lewis Field Office, completed its analysis of Ormat Inc.’s proposal for an expansion to its McGinness Hills Geothermal Facility on Jan. 18. The decision of record allows operations to begin at the Phase III project site, and construction is expected to be completed in December 2018.

Commercial production at the McGinness Hills Geothermal facility began in July 2012, and Ormat completed a second phase in 2015. The first two phases gave the complex a generating capacity of 86 megawatts, and power from phases I and II feeds the Nevada Energy grid. Once Phase III is completed, generating capacity is expected to increase to 134 MW. Phase III will contribute power to the Southern California Public Power Authority.
