Philippines: EDC Believes that Geothermal is the Key to Establishing a Stable Energy Baseload Suited to the Constant yet Dynamic Power Needs of the Country’s Developing Economy

Geothermal energy: The sustainable energy solution (

Energy Development Corporation (EDC) believes that geothermal is the key to establishing a stable energy baseload suited to the constant yet dynamic power needs of the country’s developing economy. 

Fed by the earth’s natural, abundant, and readily available heat, geothermal is able to provide clean, reliable, renewable energy 24/7, rain or shine, all year round, which is vital for consumers, businesses and industries in all sectors.

Harnessing geothermal energy is also an act of harmony with the environment. The sites where EDC operates in are proof of the symbiosis between man and nature that is genuinely possible—communities of practice where health, safety, and local livelihood thrive in tune with the flourishing natural environment of forests and watershed.

Geothermal is perhaps the only clear solution to meeting today’s energy needs without mortgaging natural resources at the expense of future generations—effectively breaking the perilous downward spiral of destruction the world faces and paving the way for a sustainable energy future.

USA, Oklahoma: GRC Member Conducts Rock Fracturing Experiment to Demonstrate Potential of Enhanced Geothermal Systems

EERE Success Story—University of Oklahoma Scientists Crack the Case Wide Open for Enhanced Geothermal Systems (EERE/GTO)

Researchers at the University of Oklahoma (OU) recently conducted an unprecedented rock fracturing experiment that showcased the potential for enhanced geothermal systems (EGS) as a viable power source for the United States.

Supported by funding from the Energy Department’s Geothermal Technologies Office (GTO), Dr. Ahmad Ghassemi - a GRC member - and his research team of graduate students successfully fractured and stimulated a series of 13-cubic-inch blocks of granite and other igneous rocks found in EGS reservoirs.

The OU team was able to extract more than 50 watts of power production from the small rocks, which is equivalent to a household light-bulb, showing promise that field-scale fractures and a properly engineered EGS can produce considerable amounts of power.

USA, California: Geothermal Energy Helps the Golden State through a Bad Weather Day

Geothermal Energy Tops Wind and Solar in California

Southern California was battered by a big storm yesterday which affected the supply of electricity from solar and wind resources. Heavy rain resulted in mud-slides in areas that were burned in recent wildfires and snow fell on the "Grapevine" a section of Interstate 5 just north of Los Angeles.

However, geothermal energy power plants were not affected, providing electricity from a constant 1,000 MW capacity.

Yesterday in California, geothermal energy was the biggest provider of electricity from renewable resources to the CAISO grid, with over 24,000 MWh. Winds produced 23,043 MWh, solar energy (PV and thermal) peaked around 10 am and only supplied 11,062 MWh.

USA: Government Plans to Strip Away Protections for Sage Grouse

Trump Drilling Plan Threatens 9 Million Acres of Sage Grouse Habitat (New York Times)

Bird habitat in western US coincides with many geothermal energy areas

Dan Cepeda/The Casper Star-Tribune,
via Associated Press
The Trump administration on Thursday detailed its plan to open nine million acres to drilling and mining by stripping away protections for the sage grouse, an imperiled ground-nesting bird that oil companies have long considered an obstacle to some of the richest deposits in the American West.

In one stroke, the action would open more land to drilling than any other step the administration has taken, environmental policy experts said. It drew immediate criticism from environmentalists while energy-industry representatives praised the move, saying that the earlier policy represented an overreach of federal authority.

United Kingdom: First Borehole Underway at UK Geoenergy Observatory for Glasgow

Glasgow geothermal project heats up with first borehole (NERC)

The first borehole is underway at the UK Geoenergy Observatory for Glasgow, allowing scientists to 'see' underground at the world-class geothermal energy research site in the east end of the city.

Marking the beginning of the 15-year research investment, a 7·2-meter high drilling rig broke ground on the site to form the first borehole for the observatory.

Over the next 15 months, the drilling team will create 12 boreholes of various depths, which will enable research into Glasgow's geology, its underground water systems and the potential for heat from the water in the city's disused coal mines. One of the biggest aims of the project is to find out whether there is a long-term sustainable mine water resource that could provide a low-cost, low-carbon heat source for homes and businesses.

United Kingdom: BGS Geochemist Writes About his Geothermal Energy Adventures

Feeling the heat: exploring the potential for geothermal energy (GeoBlogy)

by Chris Rochelle, Geochemist - British Geological Survey

I write the first part of this blog on the return leg of a long-haul flight from Mexico where I have attended a meeting of the GEMex project - a €20M EU-Mexico collaboration which aims to enhance understanding of two geothermal systems east of Mexico City. Over 100 scientists from across Europe and Mexico spent 4 days visiting working geothermal operations, discussing their latest data, and trying to combine many different strands of research into coherent models for the two study sites.

Developing Los Humeros and Acoculco, and other systems, will help Mexico achieve its own target of 50% of its energy from ‘clean energy sources’ by 2050. The knowledge learned will also help in Europe’s geothermal development, which could provide an important contribution towards the European target of at least 20% of its total energy needs being via renewable sources by 2020, and 32% by 2030.

On returning to the UK I travelled to Cornwall where a large drilling rig is being erected at United Downs. Once assembled, it will spend some 7 months drilling two deep boreholes into the Carnmenellis Granite, one of which could be up to 4.5km deep (thereby becoming the deepest onshore borehole in the UK).

Science & Technology: Shallow Low Temperature Reservoirs in Sedimentary Basins May be Optimal Targets for Geothermal Energy Production

Optimization of Geothermal Energy Production (LinkedIn)

By William Harrar, Reservoir Engineer

Many of the sedimentary basins throughout the world contain several geothermal reservoirs that are potentially attractive for the production of geothermal energy. The big question is which reservoir to develop for the production of geothermal energy?

Last week, I attended the German Geothermal Congress in Essen and gave a presentation that summarizes work that my colleagues and I at Ross DK and GEOOP have been doing on evaluating geothermal energy projects with the objectives of maximizing geothermal energy production, while minimizing risk and cost.

In summary, for basins filled with clastic sediments, shallow low temperature reservoirs may be the optimal targets for maximizing geothermal energy production while minimizing risk and cost.

Italy: Recognition for Traditional Geothermal Power Plants from Industry Association

Italian industry association recognizes conventional geothermal power plants as key for Italy’s renewable production (EGEC)

The General Confederation of Italian Industry (Confindustria) published this week a “White Paper for an Efficient development of Renewable Energy Resources in Italy to 2030” (in Italian). Confindustria recognizes traditional geothermal power plants as the main components of Italy’s geothermal production.

In recent weeks, a debate started in Italy concerning an upcoming decree from the Italian Ministry for Economic Development, named FER1, set to renew subsidies for the electrical production from Renewable Energy Sources (RES). One of the most contentious elements of the proposed decree is the elimination of traditional geothermal from the renewable energy sources eligible for the subsidies dedicated to mature technologies.

On the background of this debate, Confindustria recently published its White Paper for an Efficient development of Renewable Energy Resources in Italy to 2030, which provides additional key elements to the discussion.

USA, Hawaii: “We definitely have the resources... to do modern, safe geothermal power production.”

Geothermal energy a 'no brainer' for Hawaii (PBN)

Exploration efforts in the '70s and '80s suggest that there may be more than 1,000 MW of geothermal reserves on Maui and the Big Island.

One of the most abundant renewable energy resources in the Hawaiian Islands is geothermal energy, but due to the eruption of the Kilauea volcano on Hawaii’s Big Island in early May and the subsequent shutdown of the state’s only geothermal power plant, Puna Geothermal Venture (PGV), its future is uncertain.

Though PGV owner Ormat Technologies Inc. intends to reopen the 38-megawatt facility as soon as possible, others advocate for new geothermal drilling sites that incorporate the use of safe, modern technologies.

“PGV is an old technology that has been around for decades and it’s not as efficient and not as safe as what’s being installed in many other countries around the world today,” state Rep. Chris Lee, chair of the Committee on Energy and Environmental Protection, told PBN in a recent interview. “We definitely have the resources, not only on the Big Island, but in other places too, to do modern, safe geothermal power production.”

Italy: Tuscan Communities Express Support for the Geothermal Energy Industry

Italy’s clean energy town asks why populists are abandoning it (Energy Voice)

Nicola Verruzzi.
Photographer: Alessia Pierdomenico/Bloomberg
For at least a dozen villages surrounding Montieri, capping incentives for geothermal wells would be both a financial and emotional blow. The Tuscan region gets about 30 percent of its power from geothermal sources, with zero emissions.

And while only 2.3 percent of Enel’s power generation comes from the wells, they play a crucial role in guaranteeing stable electricity output to the grid. Unlike wind or solar farms, the power from geothermal wells flows without interruption. If the government moves ahead with limiting geothermal incentives, Enel could miss out on about 600 million euros ($681 million) of investments, according to a person close to the situation who asked not to be named because the estimates are confidential. The company declined to comment.

Malaysia: Approval for 37 MW Tawau Geothermal Power Project Revoked

Govt scraps country's first geothermal power plant project (New Straits Times Online)

Government is willing to call for open tender if there were firms interested in continuing the project.

The approval given to Tawau Green Energy Sdn Bhd to build the country’s first geothermal power plant has been revoked on Aug 29, the Dewan Rakyat was told today.

Energy, Green Technology, Science, Climate Change and Environment Minister Yeo Bee Yin said the government decided to scrap the project due to the firm’s failure to carry out the project.

“There was no project progress and the drilling operations have ceased since the third quarter of 2016.

“It seemed that the company has ceased its operation and affairs at the site.

USA, Nevada: Ormat Plans 18 MW of Solar PV to Power Tungsten Geothermal Power Plant Parasitic Electric Load

Solar plus geothermal under review in Nevada (pv magazine USA)

The owner of the Tungsten Mountain Geothermal Unit is researching the addition of 18 MW of solar PV to power some, or all, of the site’s parasitic electric load.

The Bureau of Land Management is reviewing whether to approve a solar power plant, the Tungsten Mountain Solar Project, to complement an already existing geothermal plant. The plan is to develop up to two 9 MW-DC plants and a short transmission line (gentie line) connecting the solar facility to the geothermal component.

The purpose of the solar project is to allow project owner Ormat to maximize the energy produced by the Tungsten Mountain Geothermal Unit. The geothermal plant has a power purchase agreement signed with the Southern California Public Power Authority.

The solar facility is not designed to feed into the local power grid, and is not included in the power purchase agreement – but instead is to be used to balance out most, possibly all, of the facilities parasitic electricity load.

Climate Change: Renewables have Grown This Year, but Not Keeping Pace with Rise in CO2

Cars and coal help drive 'strong' CO2 rise in 2018 (BBC News)

A booming global market for cars has helped drive CO2 emissions to an all-time high in 2018, say researchers.

The main factor in the near 3% rise has been coal use in China, driven by government efforts to boost a flagging economy.

But emissions from cars, truck and planes using fossil fuels continue to rise in all parts of the world

Renewables have also grown this year, but are not keeping pace with the CO2 rise.

The research, carried out by the Global Carbon Project (GCP), says that this year's "strong" rise is projected to be 2.7%.

That's much bigger than 2017's 1.6%. This will worry scientists as they had seen CO2 emissions relatively flat for the three years before.

United Kingdom: Geothermal Heat Should be Regulated Like Water - BGS

Who owns geothermal heat? (BGS)

'Geothermal heat has the potential to make a significant contribution to... the UK Climate Change Act.'

'Heat, although not a "substance" in the physical sense, behaves in many ways analogous to water.'

Heat from the earth, or geothermal heat, arises from the heat dissipated from the centre of the earth and, at shallow depth, from heating by the sun. High-enthalpy (deep) geothermal heat is found within some granitic rocks due to slightly raised levels of the radiogenic isotopes of potassium, uranium and thorium.

Third Place GRC Photo Contest 2017.

Could Imperial County be the next hotbed of commercial lithium mining? County officials certainly hope so. The Imperial County Board of Supervisors on Tuesday approved a comment letter to the California Energy Commission regarding the prospect of recovering the mineral lithium from geothermal brine at the Salton Sea.

“This potential new industry holds a great deal of promise for new job creation and economic development here in Imperial County. In addition, it could serve to provide an important domestic source of a critical resource that is a key component in batteries that can be used to improve electric grid reliability and electric vehicle deployment in the state of California.

“In addition, mineral extraction, in conjunction with other renewable energy development around the Salton Sea should contribute to ongoing efforts to address issue around the troubled body of water,” the county wrote in a comment letter signed by county Supervisors Chairman Ray Castillo.

In the process of mining geothermal energy, hot brine is extracted from the earth, and minerals such as lithium, zinc and manganese are present in the hot fluid, Deputy County Executive Officer Andy Horne said. Collecting those minerals has long proven a reality, but doing so on a large-scale, commercial and economically feasible basis has yet to be done.

Horne said county officials were to meet with Berkshire Hathaway Energy (which owns CalEnergy geothermal operations) officials today to talk about lithium recovery. “I think our board is very optimistic about this. It’s been talked about for some time, but it’s gathering momentum to move this forward at some very high levels, and I think that’s encouraging,” Horne said.

Science & Technology: Report on Developing Specialised Corrosion and Erosion Resistant Coatings in Geothermal Power Plants

Report on characterisation of geothermal fluid (Geo-Coat deliverable D1.3)

The report provides the chemical composition of fluids of main concern in the Hellisheiði and Nesjavellir power plants. The sampling methods, locations and sample points are described. These analyses provide a reference for further studies on materials testing and modelling along with defining the testing environment for the Geo-Coat project, as summarised in the final chapter of this report.

Reykjavik Energy operates two co-generation power plants at Nesjavellir and Hellisheiði in the flanks of the Hengill volcano in SW Iceland. The plants are fed by over 50 production wells of variable composition, temperatures and flow rates. Most of the geothermal fluid is water that is returned into the geothermal reservoirs following heat extraction. The fluids are flashed, separated, condensed and mixed at various locations in the heat extraction process with the associated risk of scaling and corrosion if proper monitoring and mitigation methods are not in place.

India: New Data Analysis Confirms the Potential of the Puga Geothermal Field

Puga has highest geothermal potential (Tech Explorist)

Puga Geothermal Field Ladakh, by Dr. Ritesh Arya, Arya Drillers, Chandigarh, India.
GRC Photo Contest 2017.
Several locations in India are known to have a potential for production of geothermal energy. A new analysis of available data on all such sites has shown that Puga geothermal field in Ladakh could be a good site for further exploration.

A team of researchers from Birla Institute of Technology and Science (BITS) Pilani has used nine parameters to analyze data relating to Puga in Ladakh, Chhumathang in Jammu and Kashmir, Manikaran in Himachal Pradesh, Tattapani in Chhattisgarh, Unhavre Khed in Maharashtra and Tapoban in Uttarakhand. Based on this analysis, they have concluded that Puga has the most potential.

Researchers used thermo-hydro-geological data to conceptualize geothermal reservoirs and then used simulation software to assess a key parameter called ‘Useful Resource Base’ of reservoirs. URB denotes extraction temperature of a reservoir for an operation period of 20 years which is the typical lifetime for a geothermal bed. The researchers differentiated the sites based on a cumulative score computed on nine criteria like a cumulative discharge of thermal springs, minimum and maximum electrical resistivity, representative reservoir temperature and other factors.

USA, New Mexico: Renewable Energy Plan Calls for Extension of Geothermal Energy Contracts

PNM: Plan gets renewables to 20 percent of electricity sales (Albuquerque Journal)

The New Mexico Public Regulation Commission (PRC) approved Public Service Co. of New Mexico (PNM)’s 2019 renewable energy plan last week. The plan, submitted annually to the PRC, lays out efforts to meet the state’s renewable portfolio standard, which requires that public utilities derive 20 percent of their retail electricity sales from renewable sources by 2020.

The new plan essentially reaffirms projects PNM outlined in its current, 2018 plan, which included construction of 50 more megawatts of PNM-owned solar generation in 2019. The current plan also calls for extending existing contracts with third-party power producers to buy more wind and geothermal electricity from plants that are now being upgraded to increase output.

As of September 2018 New Mexico generates 9 GWh from 1.6 MW of geothermal capacity.

Kenya: KenGen to Break Ground on 83 MW Olkaria 1 Unit 6 Geothermal Power Plant

KenGen set to break ground for geothermal plant today (Business Daily Africa)

Kenya Electricity Generating Company (KenGen) is expected to break ground for the 83 MW Olkaria 1 Unit 6 Geothermal power plant in Naivasha, a project to be completed by 2021.

The electricity generator said the addition of the plant will push up its geothermal capacity which currently stands at 533.8 MW following the completion of Olkaria 1, 4 and five plants which are also due for expansion. Geothermal is considered a stable source of energy producing about 43 per cent of Kenya’s electricity.

KenGen expects to generate another 2,029MW from geothermal by 2028. 

Caribbean: 3,770 MW of Potential Geothermal Energy - Report

The Status of Renewable Energy in the Caribbean (Renewable Energy Caribbean)

Our recent report provides a snapshot of renewable energy growth in the Caribbean over the last 10 years – synthesizing data and energy statistics from over 300 projects and encompassing all major supply-side technologies such as solar, wind, geothermal, hydro, waste-to-energy, and bio energy.

There is approximately 3.1 GW of installed and operational renewable energy in the Caribbean including hydro, whose legacy is giving way to new technologies.

It is estimated that the Caribbean holds 3,770 MW of potential geothermal energy.

Geothermal, which shows little progress across the region over the ten-year period, may yet have its day in the sun. Unlike waste-to-energy, geothermal has supporters with significant capital. For instance, the multilaterals, led by the Caribbean Development Bank, the Inter-American Development Bank and The World Bank, have mobilized funding to address inherent issues around geothermal resource and project risk — although this does not necessarily guarantee success. In some of the region’s smaller markets, the question is not between geothermal and intermittent renewables, rather it is a question of one or the other.

Which will prevail in the coming years will depend on the new regional algorithm whose key components are economics, reliability — and resilience. That debate is playing out vigorously in the region as we speak.

United Kingdom: Work to Start This Month at Glasgow Geothermal Energy Research Field Site

How disused coal mines and hydrogen hold key to alternative energy storage (Compelo)

A British Geological Survey project to source geothermal energy from a closed mine in Glasgow and plans to capture wind power mid-generation are some of the alternative energy storage ideas put forward at the ERA Vision 2018 Midlands energy conference.

Underground rocks could be important to decarbonisation, according to a British Geological Survey (BGS) scientist.

Professor Mike Stevenson says: “Carbonisation was the Industrial Revolution and the earth helped us at that time. “Now I’m convinced we can use geology and the sub-surface to do the opposite.”

The Department for Business, Energy and Industrial Strategy provided a £31m grant to the BGS to develop two test sites, with one located at a deep coal mine in eastern Glasgow that naturally flooded with water recorded at about 12C.

Starting work this month, it will study low-temperature geothermal energy just below the Earth’s surface to find out if it warm water in can be used for renewable heat.

If successful, disused mines up and down the country could provide a low-cost, low-carbon heat source for homes in the future.

Iceland: Geothermal Heat Helps Grow Tomatoes and Cucumbers in Cold Climate

How Iceland harnesses hot springs to power year-round farming (World Economic Forum)

For half the year, the temperature on Pall Olafsson's remote farm in Iceland often dips below freezing and the sun barely makes an appearance.

Yet the heat and light in his greenhouses allow Olafsson to grow his juicy tomatoes and cucumbers even in the depths of winter - thanks largely to the geothermal energy that gives his tiny North Atlantic nation its title, the Land of Fire and Ice.

Olafsson credits the hot springs that bubble up from the earth a short distance away with turning Hveravellir into one of Iceland's biggest vegetable farms, producing about 500 tonnes of tomatoes, cucumber and paprika a year.

Climate Change: Important Conference Will Include Discussions on Geothermal Energy

At COP24 in Katowice, geothermal energy shows off its contribution to climate mitigation (EGEC)

Conference of the Parties (COP24) is kicking off in Katowice, Poland today. This round of international climate negotiations among partners of the United Nations Framework Convention on Climate Change (UNFCCC) is reputed the most important one following the COP21 in Paris where the parties agreed to pursue an objective of limiting the rise of global temperature well below 2°C, aiming for 1.5°C. Several events on geothermal energy are being organised.

During the two weeks of the COP, several events will showcase how geothermal energy contributes to climate change mitigation, and how it can contribute further. Poland, being a coal dominated country, is engaging seriously in geothermal energy, notably to solve the problem of air pollution from fossil fuel heating and energy poverty.

The following events are organised on geothermal energy during COP24:

New Zealand: Workers at Ngawha Geothermal Power Plant Expansion Project Live in Shipping Containers!

Container city a 'home away from home' for Ngawha Power Station workers (New Zealand Herald)

(Courtesy Northern Advocate)
Top Energy's geothermal power generation expansion at Ngawha is a huge project by Far North standards, and not only for the lines company.

With 29 shipping containers onsite, and beds for almost 50 workers, it's also the biggest accommodation project undertaken by container specialists Royal Wolf in New Zealand.

The $176 million project's village comprises 19 accommodation containers and a container hub, including a commercial kitchen, a laundry and ablutions unit, and a number of offices.

Iceland Drilling is drilling five 1,750 m wells, each taking around 30-40 days of continuous 24-hour a day activity. Royal Wolf opened a branch in Whangārei two years ago to meet growing demand for container solutions in the region, with additional containers being brought in from Auckland and the South Island for the Ngawha project.

Europe: Call for Greater Use of Geothermal Energy

Open Letter: European call for an increased use of geothermal energy (EGEC)

Geothermal energy is the energy stored in the form of heat below the surface of solid earth. The deeper one penetrates the interior of the Earth, the warmer it becomes. It is inexhaustible by human standards and so far, it has been used only to a limited extent for heating, cooling and the generation of electricity.

Geothermal energy is a largely CO2 free renewable energy source available at virtually every location. The technology is proven to reliably meet heating, cooling and electricity supply needs. Geothermal also promotes local economic development and job creation. It also is a significant contributor to energy security. Further deployment of this renewable resource requires a strong commitment by public authorities and the private sector. A major barrier to increased deployment of geothermal energy remains awareness of the technology. The support of public authorities plays a key role in promoting geothermal energy.

United Kingdom: Open Air Geothermal Lido to Open by May 26

This is the day Jubilee Pool’s geothermal spa is due to open

It will be the UK's first open-air lido that's heated by geothermal energy

In six months’ time you’ll be able to jump into the UK's first geothermal heated lido – right here in Cornwall. Penzance's iconic open air sea pool Jubilee Pool is due to open its eagerly-anticipated heated section at the end of May 2019, it has been revealed. And the pool is going to be even hotter than first expected.

Geothermal Engineering Ltd (GEL), the company which has been drilling holes into the earth below Jubilee Pool to tap into the earth's natural heat, said it found a warm water 'geothermal vein' 410 metres deep into the rock.

The hot water will now be tapped up to heat a section Jubilee Pool all year round. Speaking to Radio 4’s Peter Gibbs, Jubilee Pool Director Susan Stuart said it’s hoped the heated pool will be open to the public by May 26 – the first weekend of the summer half term holiday.
