UK Coal Miners Investigating Geothermal Energy (Resource)

Professor Amin Al-Habaibeh of Nottingham
Trent University led the study
Water from derelict UK coal mines could be used as a source of geothermal energy, according to a two-year joint study by Nottingham Trent University and Alkane Energy.

Researchers found that lukewarm water could be ‘condensed’ to provide additional heating, or cooling to local buildings.

A ground source heat pump takes water from an abandoned mine shaft and brings it to the surface where the heat can be extracted using a heat exchanger.

This is condensed and enters a heating system similar to central heating where the water is heated to a higher temperature, whilst the groundwater is replaced in the mine where it is then reheated by the geothermal energy.

Opinion: Lots of Potential, Still No Geothermal (Power Engineering)

With the international geothermal energy industry experiencing near record growth in 2014, it is curious that not a single megawatt of geothermal power is being produced in Canada.

In fact, Canada is nearly the only developed country on the Pacific Rim not producing geothermal power. This is despite British Columbia possessing world-class resources that have been identified by CanGEA's internationally peer veviewed Geothermal Favorability Maps and Resource Estimates. Indeed, this viability should not come as a surprise since Western Canada is dotted with over 150 known hot springs, which are surface manifestations of geothermal activity.

Goce Gravity Boost to Geothermal Hunt (BBC News)

The hunt for sources of geothermal energy is getting a boost from new observations of the Earth made from space.

The Goce satellite
Information about variations in gravity across the planet could help prospectors find promising locations where sub-surface heat can be exploited to generate electricity.

The data comes from Europe's Goce satellite. It mapped Earth's gravity field from 2009 to 2013 at high resolution.

This keen sensing is now expected to narrow the search for prime spots to put future power stations.
The International Renewable Energy Agency (IRENA) has released the information in a special global atlas.

In parallel, Goce scientists have been discussing the work here at the European Geosciences Union General Assembly in Vienna, Austria.


New Tool Sheds Light on Global Geothermal Energy Potentials (IRENA)

Online maps promise to decrease investment risk and increase development of geothermal energy

A new tool to investigate global geothermal energy potentials is now available online, just ahead of next week’s World Geothermal Congress in Melbourne, Australia. The new and freely available gravity anomaly maps, the product of collaboration between the International Renewable Energy Agency (IRENA) and the European Space Agency (ESA), offer a new technique to gauge geothermal potentials around the world.

As geothermal energy exists underground, it is extremely difficult to measure. Accordingly, exploration is expensive, time consuming, and risky for investors and governments. This new technique, using Global Bouguer and Free Air Gravity Anomaly Maps, enables prospectors to gauge geothermal potentials at minimum risk and minimum cost.

In a Melting Iceland, Drilling Deep to Stem Climate Change (

Tiny Iceland is a prime exemplar of the complexities wrought by warming climate. It is 11 percent covered by ice, but it is basically also one very large, very active volcanic system. The island has seen fast-increasing temperatures since the 1970s, and glaciers–a big source of tourism and runoff for hydropower–are visibly receding.

This cuts various ways. Iceland gets almost all its electricity and heat from hydropower and geothermal wells. Increased glacial runoff means increased generation potential; on the other hand, in 50 or 100 years, Iceland may be mostly land and very little ice, and the runoff could dry up. (And, as ice melts, pressure exerted on many of the 200 volcanoes declines, and some scientists believe that this could uncork more destructive eruptions.) For the time being, the country's 325,000 residents have more renewable energy than they can use, and there is a controversial proposal to extend a $2.1 billion undersea extension cord some 1,100 miles to Europe to sell the excess.

New Fracking Fluid Lowers Water, Energy Use (

Expanding fluid useful for oil, enhanced geothermal systems

Researchers at Pacific Northwest National Laboratory, Washington, U.S., have developed a new fracking fluid which requires less energy, less water and fewer chemicals than conventional fluids.

The researchers, led by Carlos Fernandez, say that the stimuli-responsive fluid could be used for oil and gas exploitation and Enhanced Geothermal Systems (EGS). EGS uses geothermal energy in rocks which do not naturally have hydrothermal systems, by artificially pumping water through. It could be a significant alternative energy source in the U.S., but development has been limited as the necessary high permeability, high-pressure reservoirs are difficult to maintain in what is naturally dry rock. Fernandez and the team believe that their new fracking fluid could help to solve this problem and make the technology commercially viable.

The new fluid is a type of aqueous polyallylamine which converts very rapidly into a hydrogel in the presence of CO2, which is commonly found in fracked wells. The hydrogel is 2.5 times the original volume of the fluid, increasing the pressure in the well and aiding the fracking process, as well as reducing the amount of water necessary for the fracking process. It is not harmful to the environment, is non-toxic, a corrosion inhibitor, a biocide, an antioxidant and is made of cheap, readily-available materials. The multi-purpose nature of the fracking fluid means that extra chemicals are not necessary.

Lib Dem Manifesto: Shale Gas Companies to Give Exhausted Wells to Geothermal Industry (Business Green)

The United Kingdom general election of 2015 will be held on 7 May 2015. The Liberal Democrat party are the junior member of the current 2010–15 Coalition Government with the Conservative party. The "Lib-Dems" put the environment on the front cover of their election manifesto today.

Among the ideas is a proposal to make it compulsory for shale gas firms to offer their exhausted wells to the geothermal energy industry free of charge.

"Once a shale gas well has been used, it must be offered at no cost to geothermal heat developers “to enable faster expansion of this renewable technology”.

On the innovation side, the party would introduce new legal framework to require regulators to facilitate the development of deep geothermal heat, large-scale heat pumps, waste industrial heat and energy storage systems.

Thoughts on Geothermal Energy Growing Pains (Proactive Investors USA & Canada)
Ross Beaty, Executive Chairman
of Alterra Power

Interview with Ross Beaty, Executive Chairman of Alterra Power

"I wanted to do something environmentally friendly that would be good for the world. That would satisfy my desire to try to reduce our carbon emissions and produce electricity that’s in clean technology, meaning geothermal, wind, hydro and solar power."

"So it was something different for me. I started the company focused on geothermal power. Both Rick Rule and I thought it was really going to be a great long term solution for the world and it turned out not to be. It turned out to be a very risky, very difficult business and we both had a lot of investment, you could say, ‘disasters’ in looking at different geothermal plays."

I had bought some assets that were producing though in the company which we have to this day. It wasn’t just an exploration play. It was a producing company right from the beginning and we took it public in 2009. In 2011, I had realized just how tough the geothermal business was. But I still wanted to build a clean energy company bigger and bigger. So I acquired a company in British Columbia called Plutonic Power and joined the two companies together into the company that is today Alterra Power."

Maibarara Geothermal Plant Expansion is On Track (Manila Standard Today)

Maibarara Geothermal Inc. said Wednesday it will proceed with the P1.3-billion expansion of the 20 MW geothermal power plant in Batangas.

Maibarara Geothermal president Francisco Delfin Jr. told reporters the company started drilling two steam wells last year to expand the project by another 10 MW. The wells are undergoing testing “to determine how much capacity it can accommodate.”

“Testing is ongoing…In the next two weeks, we believe that we have sufficient steam based on reserves estimation for the 10-MW expansion,” Delfin said.

He said the company would proceed with the financial closing for 70-percent of the project cost. Construction will start soon after that, in line with the target of completing the project by July 2017, he said.

The 20 MW Maibarara geothermal project in Sto. Tomas, Batangas started commercial operation in early 2014.

California Power Grid Seen Able to Handle 100% Renewables (Bloomberg Business)

Michael Picker, president of the 
California Public Utilities Commission
California’s power grid could handle taking 100 percent of its supply from renewables such as wind and solar, and meeting the goal for half that amount will be no problem, the state’s chief energy regulator said.

Governor Jerry Brown in January set one of the world’s most ambitious targets for cleaning up power generation, saying 50 percent of supply should come from renewables by 2030, a dramatic increase from the current goal of 33 percent by 2020. He didn’t make clear how the goal could be achieved.

Michael Picker, president of the California Public Utilities Commission, said the grid already is comfortably managing solar and wind energy that reached as much as 40 percent of the total a few days last year. In the years ahead, authorities can add the flexibility needed to manage power that flows only when the wind blows or the sun shines.

Warren Buffett's PacifiCorp Considers Joining California ISO (Utility Dive)

Expanded grid would include geothermal energy from Utah

PacifiCorp, the vertically-integrated Western utility owned by Warren Buffett's Berkshire Hathaway Inc., is considering joining the grid operated by California Independent System Operator (CAISO).

PacifiCorp and CAISO have signed a memorandum of understanding indicating that the utility will study the feasibility of becoming a transmission-owning member of the California grid.

Bloomberg Business reports that joining the grid would see CAISO take operational control of PacifiCorp's 16,300 miles of transmission lines, expanding the grid operator's territory by nearly 40%.

If PacifiCorp does join the grid operator's system, it would fully open up the California energy market to PacifiCorp's generation, including large amounts of cheap renewables, principally wind and hydropower but also the Blundell 34-megawatt geothermal facility near Milford, Utah.

DOE Estimates Annual 5.5% Growth in Geothermal Energy to 2040 (USEIA)

Projections in the Annual Energy Outlook 2015 (AEO2015) focus on the factors expected to shape U.S. energy markets through 2040. The projections provide a basis for examination and discussion of energy market trends and serve as a starting point for analysis of potential changes in U.S. energy policies, rules, and regulations, as well as the potential role of advanced technologies.

Rising long-term natural gas prices, the high capital costs of new coal and nuclear generation capacity, state-level policies, and cost reductions for renewable generation in a market characterized by relatively slow electricity demand growth favor increased use of renewables.

Renewable electricity generation in the AEO2015 Reference case increases by 72% from 2013 to 2040, accounting for more than one-third of new generation capacity. The renewable share of total generation grows from 13% in 2013 to 18% in 2040.

Geothermal generation grows at an average annual rate of about 5.5% over the projection period, but because geothermal resources are concentrated geographically, the growth is limited to the western United States. The report estimates that geothermal electricity generation will increase from 16.88 billion kilowatthours in 2015 to 69.56 billion kilowatthours in 2040.

KenGen Invites Bids for Wellhead Plants (Kenya Broadcasting Corporation)

The Kenya Electricity Generating Company, KenGen has opted to lease equipment in an initiative aimed at fast tracking geothermal generation. The firm has invited bids from firms interested in putting up wellhead plants on nine steam wells in Olkaria and Eburru geothermal fields with a capacity of 48 megawatts.

To reduce development costs, geothermal exploration firms in Kenya have adopted well head generation. Here a small generation plant of for instance 10 MW or less is installed on a well after its drilled.

To further cut generation costs, the firm now plans to lease power generation equipment for its wellhead plants from private firms with 10 years experience in geothermal power plant design, operation maintenance and transmission.

The firm is keen to get the services for power generation on 9 wells located in the Olkaria and Eburru geothermal fields totaling 48 MW.

A request for an expression of interest has already been published by the firm which currently has an installed capacity of 1,575 MW translating to 70% of the country’s total installed capacity.

How do Geysers Erupt Over and Over? (Scientific American)

Yellowstone National Park's Old Faithful mystifies and delights tourists with its recurrent eruptions. But because of its popularity, it is heavily protected: the government limits access to curious scientists and restricts experiments on its plumbing.

At least 80 smaller but equally percussive geysers also burst forth in Chile's Atacama Desert, offering an analogous opportunity to probe the earth's inner workings. Geologists laden with temperature and pressure sensors, GoPro cameras and a host of other gadgets recently observed one such geyser, nicknamed El Jefe, over the course of five days and more than 3,500 eruptions—one every 132 seconds. The result? The most detailed data set yet on the explosive choreography between water and steam.

Modoc Schools to Add Geothermal Heat (Herald and News)

Efforts to provide heat Alturas schools with geothermal energy are heating up. Construction of a $4 million geothermal heating system that will be used at three Alturas schools and the Alturas swimming pool is expected to begin this fall and be operable for the 2016, according to Tom O’Malley, Modoc Joint Unified School District superintendent.

He said the project will go out for bid in July with construction expected to begin in September. Tentative plans envision completing the work by mid-February 2016 with the system online after that.

The project will use an existing geothermal well, which previously tested at producing 400 gallons of 183-degree water a minute. According to a project report, the system will provide geothermal heat for the neighboring Modoc Middle and Elementary schools, expand the heating system at Modoc High School, and heat the Alturas swimming pool.

The entire system will be routed to a re-injection well for discharge back into the aquifer. O’Malley said the system will be designed to allow for potential future use by Modoc County facilities and a proposed new hospital.

Opinion: Could Hawaii Geothermal Plant Become a Windfall for Public? (Honolulu Civil Beat)

If power plant on Big Island were to start extracting valuable minerals like lithium on state-owned land, royalty payments should increase.

Puna Geothermal Venture (Courtesy Ormat)
An emerging technology is making it possible to extract lithium from the hot, mineral-rich brine that geothermal power plants pump out of the ground to generate energy. And the technology is not limited to extracting lithium — it can also recover a variety of other rare earth elements and valuable metals out of what is now being treated as wastewater.

In the parlance of geothermal engineering, this is called “solution mining by nature,” and the potential profits to be made from it are immense — so much so that it has gained the attention of two Hawaii County Council members, Margaret Wille and Daniel K. Paleka Jr., who are convening a hearing on the subject next month.

Does Ormat Technologies Inc. — the owner of Puna Geothermal Venture, which operates Hawaii’s only geothermal power plant — have plans in the works to adopt the technology?

The Forest Service says the springs will not be disturbed, but they are within the large tract of federal land that could one day be open for geothermal development. (Couretsy KUOW)
(Download Audio 3:50 Minutes) The volcanic ridges of the Cascades have long been poked and prodded by people who want to know what kind of geothermal energy they'll find beneath the surface.

But many of the Northwest's hot spots are on public lands. And in some cases, federal land managers have prevented access by companies seeking to convert that magmatic force into clean electricity.

That could soon change. The U.S. Forest Service is pursuing plans to make more than 80,000 acres in Washington's Mt. Baker/Snoqualmie National Forest available for lease to energy companies. A final decision on that is expected as early as this month.

“A baseload renewable resource is something to treasure. We view it as a very attractive possibility,” said Adam Lewis with the Snohomish Public Utility District. The district has spent $5 million researching geothermal developments in Washington and is interested in building a traditional geothermal plant in the Mt. Baker/Snoqualmie National Forest to power roughly 20,000 homes.

Enel Green Power in Renewables Agreement with Marubeni (International Water Power and Dam Construction)

Italian geothermal energy developer Enel Green Power (EGP) and Japan-based Marubeni Corporation are to evaluate potential opportunities for renewable energy projects, including geothermal, in the Asia-Pacific region.

The firms signed a two-year Memorandum of Understanding to cooperate in geothermal, wind, solar and hydro projects mainly located in the Philippines, Thailand, India, Indonesia, Vietnam, Malaysia and Australia as well as other areas that may be identified at a later stage.

Only projects in the development phase will be considered, therefore projects under construction and operating assets will be excluded from the scope of the cooperation. The MoU is expected to be implemented by means of development agreements aimed at setting the structure of the projects. Under each agreement, EGP and Marubeni will have to establish a joint venture to build, own and operate the relevant projects. The structure of every joint venture will secure a controlling stake on each project to EGP.

Under the MoU, EGP and Marubeni will also establish a joint working group to regularly exchange information and data on project opportunities.

Lake County’s Geysers Provides Electricity, Jobs — and Tours (SFGate)

The Sonoma power plant converts steam into energy
at the Geysers near Middletown in Lake County.
Way up in the Mayacamas Mountains of Lake County, great plumes of steam stretch toward the clouds, and the ground speaks, conversing in burbles and gasps, belches and sighs. On the hillsides all around, 83 miles of huge, silver gray pipe snake in a serpentine that looks like a massive water park slide.

It’s a magical place called the Geysers, a natural wonder spanning 45 square miles of geothermal hot springs fed by the Earth’s molten core.

Harnessed as a power plant, the site is the world’s largest geothermal electricity production facility, creating renewable, non-fossil-fuel-burning energy for large swaths of the North Bay.

Around the clock, seven days a week, its 15 plants hum quietly and efficiently, cranking out 6 million megawatts of natural, clean energy a year, enough to supply 39 percent of the United States’ geothermal generation, and 18 percent of California’s renewable electricity resources.

Next Step in Belgium Deep Geothermal Energy Project (VITO)

Earlier this week, VITO, a research and technology organization in areas of cleantech and sustainable development based in Belgium, launched an international call for tender for the soil borings up to 4 km deep, searching for hot water on the Balmatt site in Mol, in northern Belgium.

The first drilling will be realized before the end of this year. This will be the so-called exploratory drilling of the research project “deep geothermal energy” on the Balmatt site.

VITO has mapped the deep subsurface of Mol area to a depth of more than 4 km. According to the results of the measurements, researchers expect to find hot water at a depth of approximately 3.5 km, possibly even 124°C hot. Via two drilling wells, they want to pump up this hot water and pump back the cooled water. The extracted heat will be used for eg heating the VITO buildings. In case the water is hot enough, there will be tried to produce electricity in a second phase.

Three groups that hoped to speak in court about the Site C dam project have all been rejected. They include CanGEA, the Canadian Geothermal Energy Association.

Site C, approved last December, is a dam that could cost around $8.8 billion, and would be built seven kilometers from Fort St. John. Affected landowners and several local First Nations have attempted to challenge the project in court to keep it from going forward. They are set to appear in court later this month to argue their cases in a judicial review that will determine whether it can or should go to court.

On Monday, various groups argued that they should be granted “intervenor” status in the judicial review. An intervenor is a person who, even though they aren’t named as a plaintiff or defendant in a law case, wants to be added as a party to defend their interests which may be affected by the court case.

CanGEA wanted to be deemed intervenors in the landowner's case. CanGEA wanted to intervene because they have offered geothermal as an alternative to the Site C project. This court case would affect whether or not that alternative would go through.

First Round of Helicopter and Ground Surveys for Geothermal Development Completed (

Experts from New Zealand and the United States carried out helicopter surveys over the town of Soufriere over a two day period. Equipped with special devices the helicopter surveyed aeromagnetics with the aim of detecting various faults in the earth`s surface which provide conductivity for geothermal development.

Geophysicist John Seabert headed the helicopter surveys and says that the data collected is of high quality and will aid in pinpointing specific areas for possible geothermal development.

The data is being studied by scientists and processors in Denver, Colorado who are expected to submit data maps detailing their findings in the coming weeks.

Concurrent with the aerial surveys, geochemical studies were undertaken in and around the Town of Soufriere by a special team of geoscientists. Samples of water, gas, rock and soil were collected for testing that will better inform the geothermal exploration process. The results of the surveys are scheduled to be released in September 2015. The experts will next take to the air in June 2015 to conduct lidar surveys using a special small aircraft.

U.S. Power Sector Emissions Poised To Fall To Two-Decade Low In Transformative Year (BNEF)

Annual records for renewable build, coal retirements and gas burn all expected to be broken in 2015

This should prove to be a watershed year for the “de-carbonization” of the US power sector, with record volumes of coal-fired capacity to be shuttered, renewables capacity to be built, and natural gas to be consumed. The result, according to research firm Bloomberg New Energy Finance (BNEF): CO2 emissions from the power sector should drop to their lowest level since 1994.
  • This year, the US will install more renewables than ever before, with 18 new gigawatts (GW) coming online.
  • This is expected to be a record year for coal retirements in the US with 2 GW forecast to come offline. 
The result of this churn is that CO2 emissions from the power sector should fall to their lowest levels since 1994, BNEF has found. This would put power sector emissions 15.4% below 2005 levels. Overall, the US has pledged to cut all CO2 emissions (inclusive of the power, transport, agricultural, industrial, and residential sectors) by 28% by 2025 from a baseline of 2005.

The white paper is available for download here. The findings will be discussed in-depth at BNEF’s Future of Energy Summit, April 13-15 in NYC. For more information please visit:


Geothermal Energy Can Help Power Fiji (Fiji Times)

used in drilling for geothermal.
Geothermal power generation can supplement Fiji's hydro power and help reduce reliance on fossil fuels, says Geothermal Electric Ltd. CEO Tim Daniel.

He said Costa Rica was the first country to achieve 100 per cent of its electricity generation without fossil fuels for a period of more than 75 days.

"This is a remarkable achievement built on the backbone of hydro-generation and geothermal power, supplemented by solar and wind. A power generation mix we are likely to be able to emulate here in Fiji should our geothermal power projects be successful."

"And it looks like the savings on fossil fuels will deliver a cut in the electricity price of up to 15 per cent in the near future for Costa Ricans - putting cash back in the pockets of the people," he said.

He said these were the kind of savings Fiji needed and were achievable with geothermal power generation.

Civil Engineer Explores Use Of Geothermal Energy To Melt Ice on Bridges (University of Texas at Arlington)

A team of researchers from The University of Texas at Arlington is exploring ways to use geothermal energy to make bridges and overpasses safer during winter weather.

Xinbao Yu, an assistant professor of civil engineering, is the lead investigator on a 17-month, $193,000 grant from the Texas Department of Transportation that will determine the feasibility of using geothermal energy to melt ice and snow from Texas roads.

The researchers will evaluate available technology to harness geothermal energy and efficiently use it for de-icing. The process works by pumping groundwater through a circulation pipe to bring thermal energy from the ground to the surface. One end of the circulation pipe is embedded into the bridge deck, which warms to the point where ice and snow melt instead of sticking to the surface. The technology also could be used to cool road surfaces during summer months, resulting in longer life of the pavement.

Our Energy Vocabulary: The Words We Use for the Stuff We Can't See (Energy Collective)

Is geothermal energy renewable or sustainable?

It’s hard to talk about energy. Just ask any science teacher who has tried to define energy in a classroom. People stare blankly when you say, “It’s the ability to do work.” They furrow their brow when you tell them it’s not the same thing as “power.” You lose them completely if you bring up the laws of thermodynamics.

And yet, this thing that defies simple definition is critical to everything we do. Energy is fundamental to all facets of life on Earth. So it’s no surprise that folks who spend their days talking about energy have had to develop a special vocabulary, in order to have concrete discussions about an enigmatic concept.

Consider geothermal energy, which is commonly referred to as a renewable energy source. When underground hot water is tapped to generate electricity, the lost heat is then replenished over time from the large reserves of heat inside the planet. (See Chapter 4 of this IPCC special report for some helpful information on geothermal energy.) While the amount of heat stored in Earth’s core is massive (~1031J), it is also finite. We can’t get more after it’s gone. So is geothermal energy actually renewable?

To avoid this kind of semantic quibbling, many people (especially fans of nuclear energy) prefer the word “sustainable” to describe energy sources which humans could continue to exploit for many, many years.

Consultation on IRENA Global Atlas Work Programme 2016 – 2017 (IRENA)

This survey is a request to users and contributors of the International Renewable Energy Agency (IRENA)'s Global Atlas for Renewable Energy, to provide suggestions that would guide future developments of the initiative.

The Global Atlas for Renewable Energy (Global Atlas) is an initiative coordinated by IRENA, aimed at closing the gap between countries having access to the necessary data sets, expertise and financial support to evaluate their national renewable energy potential, and those countries lacking such elements.

Several parts of Australia show great potential for developing
geothermal energy, according to the Global Atlas for Renewable Energy.
The Global Atlas platform facilitates a first screening for areas of opportunity for renewable energy deployment all over the world where further assessments can be of particular relevance. It enables the user to overlay information listed in a catalog of more than 1,000 data sets, and to identify areas of interest for further prospection.

This survey would take a maximum of five (5) minutes to be completed and results would be collated latest by Tuesday 14th of April, 2015.
