Indonesia: GRC Presents a Pre-Conference Workshop at Regional Geothermal Energy Conference

6th Indonesia International Geothermal Convention and Exhibition (IIGCE)

5-8 September 2018, Jakarta Convention Center, Indonesia


Science & Technology: A Joint 3D Inversion Workflow Study of the Darajat Geothermal Steam Field

Geologically consistent multiphysics imaging of the Darajat geothermal steam field (First Break)


Darajat is a vapor-dominated, producing geothermal field in West Java, Indonesia. Located along a range of Quaternary volcanic centres, it is associated with an eroded andesitic stratovolcano, and its reservoir is predominantly comprised of thick lava flows and intrusions in a stratovolcano central facies (Rejeki et al., 2010).

First production from the field was started in 1994 with the installation of a 55 MW plant, and capacity was added in 2000 and 2007 to bring the total to 271 MW.

Several ground geophysics data sets have been acquired during successive surveys – including gravity and magnetotelluric (MT) surveys, and continuing micro-earthquake (MEQ) monitoring (Soyer et al., 2017).

While each survey was independently modelled and interpreted, a quantitatively integrated 3D inversion modelling study had not been undertaken. We present a joint 3D inversion workflow, incorporating the production field model as a structural reference in order to derive mutually consistent subsurface resistivity, density and velocity distributions, as well as relocated MEQ events.

Canada: Drilling of Four Test Wells Begins at Canoe Reach Geothermal Project

Groundbreaking: geothermal drilling finally begins (The Rocky Mountain Goat)


It’s called ‘spudding.’ It’s the process of beginning to drill a well in the oil and gas industry and Borealis GeoPower is doing it near the Kinbasket Reservoir – but it’s not oil they’re drilling for.

Borealis GeoPower, a Calgary-based energy company began drilling on Monday, June 11, and they aren’t looking for oil. They are looking for heat radiating from the earth’s core, finding its way up through the Rocky Mountain trench.

The four geothermal test wells, if successful, could give rise to the first geothermal power plant in the country, potentially supplying the valley with stable local power. The test well will show how the temperature increases with depth and, with luck, will confirm the exploration work already been done in the area over the last eight years.

This is the first exploratory drill hole in the area despite an interest in the area’s geothermal resources dating back to the 1970s.

Denmark: A New Business Model to Deliver Geothermal Heat to Danish Homes

Geothermal energy has the potential to cover 30% of Denmark’s district heating supply (News Release)


Geothermal energy is a renewable and currently untapped energy source with the potential to cover approx. 30% of Denmark’s energy supply for district heating, equaling the heat consumption of 500,000 households. That is one of the promising claims from A.P. Moller Holding who is seeking to introduce geothermal energy on a large scale in Denmark.

There are currently three minor geothermal plants in Denmark, but A.P. Moller Holding presents a new business model which differs from the existing projects. A.P. Moller Holding is responsible for exploration, construction, and operation of the plants. Hence, the consumers will not end up paying the bill if things should not proceed as planned.

USA: Regional Grid Would make it Easier to Distribute Renewable Energy

California lawmakers move closer to regional electric grid (AP News)

A contentious proposal to link oversight of California’s electric grid with other states in the U.S. West narrowly cleared a legislative hurdle Tuesday, keeping alive a proposal that has divided environmentalists over the best way to expand renewable energy.

The proposal, backed by influential proponents including Democratic Gov. Jerry Brown, seeks to make it easier and cheaper to deploy renewable energy across the western United States. But critics say California would jeopardize renewable energy mandates by sharing grid management with states that use more coal and natural gas— a possibility they see as more likely under President Donald Trump.

The proposal approved Tuesday by a Senate committee would transition the California Independent System Operator, which is overseen by a governor-appointed board, to a regional group without political appointees.

United Kingdom: Background on Geothermal Energy in the UK

Potential for geothermal energy resources in the UK (Parliament.uk)

An information pack was prepared for the debate in Westminster Hall on 19 June 2018 from 2.30-4pm on the Potential for Geothermal Energy Resources in the UK.

In the UK, there is a resource of geothermal energy at shallow depths which can be exploited with ground source heat pumps (GSHPs). GSHPs use pipes which are buried to extract heat from the ground. The upper 10–15 m of the ground is heated by solar radiation and acts a heat store.

There are some geothermal projects planned in the UK, for the generation of heat, electricity, or both. There is also a commercial plant in Southampton which in 1986, began delivering heat from a borehole to a district heating network, and is now operated by the energy firm ENGIE.

United Kingdom: Geothermal Spa Gets Planning Approval

Ambitious new geothermal hot spa at Jubilee Pool gets go-ahead (Cornwall Live)

Drilling has already started to reach the hot rocks which will mean the pool can be used all year round

An ambitious project to create a geothermal-heated spa at Jubilee Pool in Penzance has been given planning approval. It will mean the pool can open all year round and drilling has already started to reach the hot rocks which will heat the water.

Listed building consent has been granted by Cornwall Council for the project which will create a spa within one corner of the existing pool protected by a glass wind break along a new curved wall.

The water level within the new spa pool will range from 1m to 1.4m in depth and will contain fresh seawater heated to 35 degrees centigrade. The heat source for the pool will be from the 1,500m deep geothermal well currently being drilled in the triangular section of land outside the North-Eastern boundary of the Jubilee Pool site.

Europe: 2800 MW of Geothermal Electricity Capacity in 2017 - Report

EGEC Geothermal Market Report 2017


The European Geothermal Energy Council (EGEC) Geothermal Market Report confirms the trend towards the steady growth observed in recent years, but also notes the need for greater recognition in order to enable the full deployment of geothermal energy in Europe.

Installed geothermal electricity capacity in Europe amounts to 2.8 GWe, producing over 15 TWh per year. In Europe there are 117 plants, 16 of which were inaugurated in 2017. The new additions are quite significant, with 330 MWe of new geothermal electricity capacity coming online, mainly in Turkey.

The use of geothermal for heating is also increasing, supported by the construction of new district heating networks and the retrofitting of old ones, thanks to local and national planning identifying geothermal heat as a cost-efficient solution to meet heating needs. In 2017, 9 new plants were inaugurated, adding over 75 MWth across France, the Netherlands and Italy. The number of new plants coming online each year is on an upward trend, with an average annual growth rate of 10% in recent years.

Looking at individual geothermal heating systems, the shallow geothermal market remains the largest segment of the sector in terms of number of installations, installed capacity and energy produced. Individual geothermal heating systems, or geothermal heat pumps, represent over 20 GWth of heating capacity in Europe, with nearly 2 million installed units.

USA, Hawaii: PUC: Geothermal Shutdown Means Higher Rates, Dirtier Air

PUC Initiates Response Plan to Address Shutdown of Puna Geothermal Power Plant on Hawai‘i Island (News Release) 

At the request of Governor David Ige, the Hawai‘i Public Utilities Commission has met with the Hawaiian Electric Companies and Hawaiʻi Energy to develop a series of rapid response actions to address the loss of renewable generation from the Puna Geothermal Venture (PGV) power plant due to the ongoing lava flow on Hawaiʻi Island.

The PGV power plant provided 38 megawatts of firm, dispatchable renewable energy, representing about one quarter of Hawaiʻi Island’s energy supply, and more than half of all renewable energy generation on Hawaiʻi Island. In the near-term, electricity formerly provided by PGV will be generated mostly by burning fossil fuels, increasing air pollution and raising electricity prices for customers.

The PUC has asked the Hawaiian Electric Companies and Hawaiʻi Energy to take immediate steps to respond to the economic, reliability, and renewable energy impacts created by the natural disaster.

USA, California: The Heat Below the Salton Sea Geothermal Field

Hawaii's volcanoes are erupting. Do you know about the active volcano near California's Salton Sea? (The Desert Sun)


Volcanoes are not only potentially disruptive to the state's system of energy distribution, they can also act as power sources themselves.

The Salton Buttes sit on top of the largest geothermal field in the world, according to Alex Schriener, an associate geologist at geotechnical engineering company Earth Systems and former employee of CalEnergy.

CalEnergy owns 10 geothermal facilities in the Imperial Valley, with the capacity to produce 338 megawatts of power, according to the company website.

"All geothermal plants work on a similar principle," said Schriener. In the case of the Imperial Valley power plants, hot water is pulled from the ground, decompressed –meaning it is turned into steam in a low-pressure tank – and that steam is then used to run a turbine, translating the geothermal energy into electric power.

The geothermal field that sits below the Salton Buttes is not only the largest in the world, it is also one of the hottest. "Some wells are hotter than 600 degrees Fahrenheit," Schriener said. "Pretty darn hot."

Canada: Building Stirling Engines that Run on Ultra-Low Geothermal Resources

Can’t stop the engines (University of Alberta -  Future Energy Systems)

Technology that could generate emissions-free power from Alberta’s geothermal reservoirs is full of lessons for Future Energy Systems graduate students

David Miller is an engineer in the most classic sense: along with his fellow Master’s students Calynn Stumpf and Jason Michaud, he builds engines in the University of Alberta’s Dynamic Thermal Energy Conversion Laboratory (DTECL). But these are different engines than the ones in our cars –– they’re called Stirling engines and are based on a 200-year-old design that converts heat from any source into electricity. Since the heat doesn’t have to come from the burning of hydrocarbon fuels, that means they can generate electricity without any carbon dioxide emissions.

As part of Dr. David Nobes’ team in the Future Energy Systems project Optimizing Geothermal Energy Production and Utilization Technology, David, Calynn and Jason are redesigning these engines to work with renewable heat sources. With every roadblock they overcome, they’re moving their designs closer to potentially remaking the geothermal energy landscape.

Their main challenge: building Stirling engines that run at an ultra-low temperature differential, and then creating a model that their successors can use to scale up.

United Kingdom: Dr Charlotte Adams Wins Prestigious Medal for Ground Breaking Work in Ultra-Low Enthalpy Geothermal Energy

Dr Charlotte Adams wins Geological society medal (Durham University)

Dr Charlotte Adams
Dr Charlotte Adams, Durham Energy Institute fellow, has been awarded the prestigious Aberconway Medal by the Geological Society. This prestigious medal is awarded for excellence in applied geoscience and reflects Charlotte's ground breaking work in ultra-low enthalpy geothermal energy.

Heat can be extracted from the water flooded coal mines. The legacy of mines in the UK, their abundance and their distribution is such that most of the major population centres in the UK could have heat supplied from such mines allowing the UK to improve its energy security while simultaneously decarbonising heat. Translation of theory to practise is underway and Charlotte’s work in the area has made a significant contribution to this.

The award was presented at the Geological Society’s Presidents Day on 6th June.

Science & Technology: Making Geothermal Solutions More Cost-Effective - An Opinion

New Technologies Make Geothermal Solutions Cost-Effective: Interview with Carlo Dietl (AAPG)

Carlo Dietl is a structural geologist and petrologist working with Gesteinslabor Dr. Eberhard Jahns in Germany.

Geothermal energy from lower temperature (low enthalpy) sources is an increasingly important source of renewable, sustainable energy. Welcome to an interview with Carlo Dietl, who works with both low and high enthalpy geothermal energy sources, and who discusses some of the recent breakthroughs in technology used in geothermal energy.

Why are people and governments pursuing geothermal energy in Europe?
In fact, geothermal energy could be pursued much more. This is in particular true for deep geothermal projects (deeper than 400 m). What is a pity: geothermal energy is the only base load capable regenerative energy source! Main reason for the reluctance is the above mentioned “fracking fear” which for example even led to a general fracking ban in Germany. Moreover, and funny enough, geothermal energy is competing with other regenerative energies. Many politicians and managers of municipal utilities only promote one regenerative energy source instead of looking for a combination of several options.

USA, New Mexico: Valles Caldera Geothermal Resources Put Off Limits to Development

Geothermal Development Prohibited Near Valles Caldera National Preserve (NCPA)

The Santa Fe National Forest's decision protects the unique thermal features in Valles Caldera National Preserve

The Santa Fe National Forest finalized a decision to prohibit energy development on 195,000 acres of land adjacent to Valles Caldera National Preserve. The lands have been under consideration since 2015 to be leased for geothermal development.

Valles Caldera National Preserve is one of the newest units in the National Park System and contains some of the most extensive geothermal activity in the West, including hot springs, bubbling mudpots and steaming fumaroles. The most active geothermal features in the caldera are on a 40-acre private inholding that NPCA, working with a conservation buyer, protected from additional development and is now working its way through a transfer of ownership to the Park Service.

Norway: 1,520 Meter Well Drilled for Geothermal District Heating Project at Airport

Why is an airport drilling Norway’s deepest borehole? (Standbynordic.com)


Norway’s deepest geothermal borehole is now under construction at Oslo Gardermoen Airport. The natural heat generated from it will be used to heat the engine test site in winter.

Airport operator Avinor is managing the energy project, called Rock Energy, in partnership with the company Båsum Boring through its joint venture Norwegian Energy Drilling.

In a controlled manner, the idea is to send cold water deep underground, where it is heated and then returned to the surface.

“We’ve drilled to a depth of 1,500 metres for both boreholes, and when the project is completed they should be capable of heating the entire area of the engine test site. This has never been achieved before in Norway,” says Thor Erik Musæus, the project’s general manager, who adds that the extracted energy could also be used to heat large buildings.

Science & Technology: Abandoned Geothermal Energy Wells can be Repurposed as Energy Storage Facilities

To hit climate goals, Bill Gates and his billionaire friends are betting on energy storage (Quartz)

Quidnet Energy co-founder Aaron Mandell (also co-founder of Altarock) says this abandoned well at the Blue Mountain Geothermal Area in Nevada could store up to 30 megawatt-hours of electricity in the form of compressed water. (Aaron Mandell via Twitter)

The world needs radical new energy technologies to fight climate change. In 2016, Quartz reported that a group of billionaires—including Bill Gates, Jeff Bezos, Jack Ma, Mukesh Ambani, and Richard Branson—launched Breakthrough Energy Ventures (BEV) to invest at least $1 billion in creating those technologies.

Now, 18 months later, Quartz can reveal the first two startups that BEV will be investing in: Form Energy and Quidnet Energy. Both companies are developing new technologies to store energy, but taking completely different approaches to achieve that goal.

Quidnet’s technology uses water to store energy, but without the need for rivers or dams. Instead, it uses excess electricity to pump water into the underground shale rock found in new wells dug for the purpose or in abandoned oil-and-gas wells. After water fills up tiny cracks in the rock, forcing more in creates pressure, which compresses shale like a spring. When energy is needed, the pressure is let off and the water that gushes out is used to run turbines that re-generate electricity.

Before BEV’s investment, Quidnet had raised $1.5 million through the Clean Energy Venture Group and Prime Coalition. In 2016, the startup ran tests in Texas and Nevada to show that the technology can work. Next, it will use the $6.4 million raised through BEV and Evok Innovations on more field trials to develop the technology, which, according to Joe Zhou, the company’s CEO, can offer energy storage at much lower costs than pumped hydro, while avoiding the inherent disadvantages of building dams and surface reservoirs.
