Philippines: Government Fast-Tracks Geothermal Energy Projects

Permits fast-tracked for energy projects (BusinessWorld Online)

The Department of Energy (DoE) has certified four new projects as nationally significant, adding to its list of projects that will enjoy a faster permitting process under a law that seeks to ensure energy security in the country.

The department identified the four entities with newly issued certificates of energy project of national significance (EPNS) as Galoc Production Co., Energy Development Corp. (EDC), Therma Marine, Inc. and Philippine Geothermal Production Company, Inc.

Philippine Geothermal’s Mt. Malinao geothermal project was the latest to be certified on Sept. 20, although the DoE has yet to release details of the venture. The others include EDC, with its Mahanagdong geothermal brine optimization plant.

The issuance of the certificate for nationally significant projects is stipulated in Section 5 (a) of Executive Order (EO) No. 30 s. 2017, which intends to establish a simplified approval process and harmonize the relevant rules and regulations of all government agencies involved in the permitting process.

Climate Change: Renewable Energy Technologies Offer a Glimmer of Hope for Reducing GHG Emissions.

Emissions Gap Report 2019 (UN Environment Programme)

The summary findings are bleak. Countries collectively failed to stop the growth in global GHG emissions, meaning that deeper and faster cuts are now required. However, behind the grim headlines, a more differentiated message emerges
from the ten-year summary.

A number of encouraging developments have taken place and the political focus on the climate crisis is growing in several countries, with voters and protestors, particularly youth, making it clear that it is their number one issue. In addition, the technologies for rapid and cost-effective emission reductions have improved significantly.

Since 2010, the global weighted average levelized costs of electricity (LCOE) from solar photovoltaic, onshore and offshore wind projects, bioenergy and geothermal, have all reduced and are approaching the lower range of fossil-fuel-fired power generation costs.

Education: Three Webinars on Enhanced Geothermal and Superhot Systems

The GEMex project is organising a series of information webinars on EGS and Superhot Systems.

GEMex is joint Mexican and European project that focuses on resource assessment, reservoir characterization and concept development. The project aims to adapt and further develop methods and technologies at two unconventional geothermal sites in Mexico: Acoculco and Los Humeros. These sites are located in the eastern part of the Trans-Mexican Volcanic Belt.

The Acoculco geothermal field is described as a high-temperature geothermal system. Two wells have been drilled and found temperatures above 300°C at depths below 1800m, but hardly any fluids. Preliminary studies consider Acoculco a candidate for the application of EGS technologies.

Los Humeros geothermal field is currently conventionally exploited with a geothermal power plant in operation since 1990: Temperatures around 380°C were found at depths below 2000m. Los Humeros holds the potential of a superhot resource.

In order to have a EU-MEX joint participation to the webinars they are scheduled
at 7:00 AM - 8:00 AM PST:

Germany: Insheim Geothermal Power Plant to Supply Brine for Lithium Extraction Demonstration Plant

Vulcan inks lithium brine supply deal with German giant (FinFeed)

Vulcan Energy Resources Ltd has signed a Memorandum of Understanding (MoU) with Pfalzwerke geofuture GmbH, part of the German utility and international energy provider Pfalzwerke Group.

The MoU constitutes an initial collaboration period, during which Pfalzwerke geofuture will supply live brine and well data from its operational geothermal power plant for Vulcan to use in its pre-feasibility study (PFS).

The Insheim plant is currently pumping lithium-rich brine to the surface for energy generation, but not processing and extracting the lithium, before the brine is reinjected into the reservoir. The Insheim plant operates with a thermal water temperature of 165oC, producing a maximum of 4.8 MWe power and 10 MWth thermal energy.

As part of this DFS, Vulcan will construct and implement a demonstration plant at Insheim. Following completion of the DFS, Pfalzwerke geofuture can then choose to co-contribute to the construction of a commercial-scale lithium plant on site, or dilute interest to a royalty on lithium production.

New Zealand: Lithium Successfully Extracted from Ohaaki Geothermal Power Station Brine

Taupō company successfully extracts lithium from geothermal fluid (Stuff)

Geo40's commercial demonstration plant at Ohaaki.
A Taupō company has made a breakthrough in extracting near battery-grade lithium from geothermal fluid which its says could be a gamechanger.

Geo40 chief executive John Worth said the earth mineral was highly prized, with battery-grade lithium selling for US$10,000 (NZ$15,600) a tonne.

The commercial demonstration plant at Contact Energy's Ohaaki geothermal power station was originally built to extract silica, a mineral abundant in geothermal brines, but which blocks up pipes, Worth said.

Silica had to be removed before the lithium in geothermal brines could be extracted, he said.

Geo40 has been extracting silica for a some time, but the leap forward to lithium extraction was providing new commercial potential for the firm, he said.

USA, Washington D.C.: GREEN Act Would Retroactively Extend Production Tax Credit for Geothermal Energy

GRC letter of support of the Growing Renewable Energy and Efficiency Now (GREEN) Act discussion draft

Dear Chairman Neal and Ranking Member Brady,

On behalf of the geothermal industry we write in support of Section 102 of the Growing Renewable Energy and Efficiency Now (GREEN) Act discussion draft.

As the professional association for the geothermal industry and community, the GRC can attest to the vital importance of the tax credits to the success of geothermal energy business, and strongly supports and applauds your leadership in extending the §45(d) and §48 tax credits for baseload renewable energy technologies. The GREEN Act would retroactively extend the §45(d) production tax credit (PTC) for geothermal energy, which expired at the end of 2017, and extends the §48 investment tax credit (ITC) and provides a 30% ITC for geothermal plants that begin construction by the end of 2024. These tax credits provide a predictable market signal for project development, which in turn leverages private investment and promotes job creation and local economic benefits across the country.

Geothermal power is a critical source of renewable electricity for U.S. households and businesses as we transition to a clean energy future. It is affordable, reliable and plays a critical role in maintaining a functioning electric grid – due to its position as flexible, renewable, baseload resource that can complement other intermittent renewable resources. Extension of the expired tax credits will play an important role in continuing the development and support of our industry.

The GRC is a non-profit professional association for the geothermal industry and community in the USA and abroad. We were founded in 1972 and are headquartered in Davis, California. We have over 1,300 members from around the world and are working to advance our industry by supporting the development of geothermal energy resources through communication of robust research, knowledge and guidance.

We thank you for your consideration. We are available to answer questions and discuss further at your convenience.

United Kingdom: Plans for Enhanced Geothermal System at Eden Project

Digging into Eden Project’s Hot Rocks energy plans (New Civil Engineer)

The aim of the project titled Hot Rocks is to eventually sink two wells, one to provide heat for the project itself and another to provide power.

The engineering work has been overseen by EGS Energy, which has experience on commercial scale geothermal projects in both Cornwall and worldwide. 

EGS operations director Tony Bennett said it was the ideal place to take advantage of the potential for geothermal energy: “One of the big advantages of the Cornish granite is that it contains a certain level of radioactive minerals, which are giving off heat all the time. That means that the heat flow within the Cornish granite is higher than you get elsewhere in the UK.”

The well is drilled over 4km deep where the rock temperature is up to 190oC bid. Water injected down the will be returned to the surface at closer to 175oC.

A key to the technique is that the rock also has fissures within it.

Bennett explains: "The [soil] structure we are targeting has got the right orientation as it's very steeply inclined, we believe it'll comprise fractures .. therefore, will have a lot more pathways that the water will be able to flow through."

The first well will be drilled in a staged approach with a narrowing diameter as it deepens. The final open hole diameter will be 216mm.

If the trials are successful,  the Eden Project could form the bedrock for further geothermal plants in the UK.

South Africa: Discovery of Hotspot Could Lead to Geothermal Energy Development

Geologists uncover geothermal energy potential in South Africa (ESI Africa)

Location of study area and relevant geological features. (Courtesy Authors)
The discovery of gases released from deep beneath the earth’s crust could help to explain Southern Africa’s unusual landscape, a study suggests.

Scientists have long puzzled over why areas such as South Africa’s Highveld region are so elevated and flat, with unexpectedly hot rocks below the surface.

Hotspots are known to generate volcanic activity in Hawaii, Iceland and Yellowstone National Park.

Geologists have revealed that carbon dioxide-rich gases bubbling up through natural springs in South Africa originate from a column of hot, treacle-like material – called a hotspot – located deep inside the earth.

In South Africa, the hotspot pushes the crust upwards, generating the distinctive landscape, which consists mostly of tablelands more than one kilometre above sea level, the researchers say.

This also explains why rocks beneath the region are hotter than expected – a property that could be harnessed to generate geothermal energy.

USA: Geothermal Capacity Factor Averages 76% the Highest Among Renewable Energy Technologies

Nearly half of U.S. geothermal power capacity came online in the 1980s (EIA)

Geothermal energy has been used to generate electricity in the United States since the early 1960s. The United States has 2.5 gigawatts (GW) of operating geothermal capacity, about half of which came online in the 1980s. EIA expects three plants with a combined capacity of 115 megawatts (MW) to come online in 2020. Nearly all U.S. geothermal capacity is located in California and Nevada.

Geothermal is similar to other renewables in that it does not consume fuel to generate power, which means relatively low operation and maintenance costs, and it typically has low emissions of criteria pollutants. However, geothermal is different from other renewable technologies because it is not dependent on seasonal factors such as precipitation, wind resources, or exposure to the sun (solar insolation) and it provides a constant source of energy.

As a result, geothermal power plants tend to have high and relatively flat capacity factors throughout the year. Geothermal capacity factors in the United States averaged 76% in 2018, the highest among renewable energy technologies.

Geothermal technology is geographically limited to areas with suitable hydrothermal reserves. The technology also has relatively high capital costs and carries investment risk because of long project lead times and payback periods. In the 1980s, about 100 MW of geothermal capacity was added each year. Since then, geothermal installations have slowed because of geographical limitations, declining wholesale electricity prices, and declining costs for other renewable technologies.

Geothermal sites for power generation typically have high temperatures, relatively shallow depths, and naturally occurring underground hydrothermal reserves in permeable rock. A 2008 U.S. Geological Survey (USGS) study estimated a total U.S. resource potential of 9 GW of electric power generation from identified hydrothermal sites and up to an additional 30 GW from unidentified hydrothermal sites.

Most of this identified resource potential is in the western part of the United States. About 94% of the current U.S. geothermal generating capacity is in California and Nevada. Five other states—Hawaii, Idaho, New Mexico, Oregon, and Utah—also have geothermal power plants. The three new geothermal generators expected to come online in 2020 are in California and Nevada.

Currently, 25 states and the District of Columbia include geothermal as an approved resource to meet their Renewable Portfolio Standards (RPS). Since 1980, geothermal power plants have also received the support of a federal 10% investment tax credit (ITC), and they were eligible to receive a $0.023 per kilowatthour production tax credit (PTC) in lieu of the ITC from 2005 to 2017.

Germany: Call to Develop Geothermal District Heating Networks from Deep Resources

Industry associations call for masterplan to boost deep geothermal energy (Clean Energy Wire)

Germany needs a masterplan for deep geothermal energy in order to reap the technology's unused potential to lower CO2 emissions from heating, four industry associations have said in a joint paper.

The 37 deep geothermal plants in operation today produce 1.2 terawatt hours (TWh) of climate neutral heat per year. The Leibniz Institute for Applied Geophysics (LIAG), however, estimates that deep geothermal energy - mostly using boreholes that are 2,000 to 3,000 metres deep - has the potential to provide Germany with 100 TWh of heat per year by 2050 – almost 17 percent of the country's expected demand for heating at the time. 

Channeling geothermal energy through the country's district heating network would be a "logical" and efficient path – and could in the future replace coal-fired heating, write the German Association of Local Utilities (VKU), German Renewable Energy Federation (BEE), the German Geothermal Association (BVG) and Energy Efficiency Association for Heating, Cooling and CHP (AGFW). The associations propose that the current framework conditions for geothermal energy should be developed in order to make projects more attractive.

  • Geothermal energy results from the heat generated by Earth; it is converted to electricity or used directly.
  • There is no doubt that geothermal energy will be a huge success in the near future. We will need renewable and clean sources of energy that are always on, no matter the time or the weather—sources like geothermal energy, which supplies energy continuously.
  • One of the benefits and challenges of geothermal is that it is completely hidden from us underground (that means it has a low profile, but it also easily overlooked).
  • Geothermal industry types:
    • Extraction of hydrothermal hot water from deep underground to generate power.
    • Direct use of cooler hydrothermal hot water
    • Geothermal heat pumps that cool or heat individual buildings or houses
    • Enhanced geothermal systems can be used in locations that would not normally be suitable for geothermal energy, but they are still in the research phase
  • California will have 60 percent renewable energy by 2030, and other states will follow.
  • In the United States, California is the largest producer of geothermal energy.
  • Geothermal energy provides a flexible baseload and can provide resilience, reliability, and stability as we transition to renewable energy.
  • Geothermal power production creates quality jobs and contributes to local economies near the resources. For every two megawatts of geothermal development, five quality jobs are created.
  • Geothermal is a facilitator of other, intermittent renewables. The renewable power industries can collaborate for the benefit of everybody.
  • A recent study by the Department of Energy stated that geothermal energy could provide over 60 gigawatts of power, which would be over 10 percent of U.S. electricity demand.
  • The Geothermal Resource Council supports the Geothermal Energy Opportunities (GEO) Act, The Advanced Geothermal Innovation Leadership (AGILE) Act of 2019, and the Enhancing Geothermal Production on Federal Lands Act.
  • Geothermal developers are looking at ways to increase the value of geothermal plants. One way to achieve this is through co-production of minerals. Lithium, for example, is found in geothermal brines, especially in the Imperial Valley in California, and it could potentially be recovered from the brine. The demand for lithium, used in lithium-ion batteries (for smartphones, laptops, electric vehicles, energy storage…), is expected to increase significantly over the next 10 years.
  • The geothermal industry is helping build a future where geothermal power and heat can be rolled out across the nation as a critical source of renewable energy.

Science & Technology: Geothermal is "carbon-free, renewable, and efficient"

Tech Breakthrough Could Spark A Geothermal Energy Boom (

"Geothermal Drilling", by Vilhjálmur Guðmundsson, Reykjavik, Iceland. Honorable Mention GRC Photo Contest 2019.
Geothermal energy is often billed as one of “the cleanest energy sources” --and with good reason. It’s carbon-free, renewable, and efficient. Even those stoic anti-hyperbolists over at the United States Department of Energy sing its praises, saying, “this vital, clean energy resource supplies renewable power around the clock and emits little or no greenhouse gases -- all while requiring a small environmental footprint to develop.”

Luckily, there has recently been an important breakthrough in the field of geothermal energy exploration and finding those geothermal hotspots (so to speak) thanks to a team of research scientists from the GFZ German Research Centre for Geosciences, based in Potsdam.

USA, Washington D.C.: Hope for Geothermal Energy in Draft of Growing Renewable Energy and Efficiency Now (GREEN) Act

This draft legislation is a comprehensive approach to tackling climate change by using the tax code to extend and expand renewable energy use and reduce greenhouse gas emissions.

You can click here to read the discussion draft of the GREEN Act and click here to view a section-by-section of the legislation.

Selections pertaining to geothermal from the section by section analysis of the discussion draft:
The production tax credit (PTC) for geothermal energy is revived and extended through the end of 2019. Separately, geothermal is made eligible for a higher investment tax credit under § 48 starting in 2020. See sec. 102 of the discussion draft.
The investment tax credit (ITC) for geothermal energy property is modified to match the credit timeline for solar energy property. Therefore, the ITC for geothermal energy property is 30% through the end of 2024. The ITC then phases down to 26% in 2025, 22% in 2026, and 10% thereafter. Geothermal will not be eligible for the PTC after 2019. See § 101 of this discussion draft.
“The geothermal industry is helping build a future where geothermal power and heat can be rolled out across the nation as a critical source of renewable energy for U.S. households and businesses as we transition to a clean energy future.

The Geothermal Resources Council (GRC) can attest to the vital importance of tax credits to the success of geothermal energy business, and strongly supports and applauds the leadership shown by the House Ways and Means Subcommittee on Select Revenue Measures, and Chairman Mike Thompson, in drafting the Growing Renewable Energy and Efficiency Now (GREEN) Act.

The GREEN Act would retroactively extend the Production Tax Credit (PTC) through 2019 for geothermal, which otherwise expired at the end of 2017, and extends the Investment Tax Credit (ITC) at 30% for geothermal plants through the end of 2024. These tax credits provide a predictable market signal for project development, which in turn leverages private investment and promotes job creation and local economic benefits across the country.”

Croatia’s first geothermal power plant, the 16.5 MW Velika 1 in Ciglena near Bjelovar, has been officially unveiled in a ceremony attended by Croatian Minister of Environmental Protection and Energy Tomislav Ćorić and Muharrem Balat, Chairman of the Board of Turkey’s MB Holding, which owns the plant. Europe’s biggest binary power plant was built in an investment of HRK 325 million (around EUR 43.7 million).

The Velika 1 geothermal power plant was put into operation in December 2018, and has been operating at full capacity since March 2019, supplying electricity to almost the entire city of Bjelovar. The plant’s core technology was produced by Italy’s Turboden, while domestic suppliers and contractors accounted for over 68% of the total investment, according to the Croatian Renewable Energy Sources (OIEH) association.

Project manager Dragutin Domitrović said that Velika 1 has a power purchase agreement with the Croatian Energy Market Operator (HROTE) for 10 MW of installed capacity, which corresponds to the average consumption of 29,000 Croatian households.

Canada: Lithium Extraction Pilot Plant Sources Geothermal Brine from Leduc Reservoir in Alberta

E3 Metals to scale up testing with large lithium-enriched brine sample (JW Energy)

(Courtesy E3 Metals)
Calgary-based E3 Metals says it has collected the largest sample to date of lithium-enriched brine from its project in Alberta.

The 20,000-litre sample was collected from the Leduc Formation in what the company calls its Central Clearwater Resource Area.

The work was completed with assistance from a local oil and gas operator with whom E3 Metals has been actively collaborating since 2017, the company says.

E3 says the sample is required to support the continued testing and scale up of its proprietary direct lithium extraction process over the next 12 months.

The company has delineated an inferred resource estimate of 6.7 million tonnes of lithium carbonate equivalent from brine in the Leduc Formation, which now ranks Alberta as having one of the largest lithium resources in the world.

Science & Technology: Direct Thermal Charging Cell for Converting Low-Grade Waste Heat to Usable Electricity

Dr. Tony Shien-Ping Feng of the Department of Mechanical Engineering at the University of Hong Kong (HKU) and his team invented a Direct Thermal Charging Cell (DTCC) which can effectively convert heat to electricity, creating a huge potential to reduce greenhouse effects by capturing exhaust heat and cutting down primary energy wastage.

Low grade heat is abundantly available in industrial processes (80 to 150°C), as well as in the environment, living things, solar-thermal (50 to 60°C) and geothermal energy. 

Dr. Feng said: "Efficient low-grade heat recovery can help to reduce greenhouse gas emission but current technologies to convert this heat to electricity is still far from optimum. DTCC yields a conversion efficiency of over 3.5%, surpassing all existing thermo-electrochemical and thermo-electric systems, which is either too costly or complicated, or too low in efficiency for everyday applications. DTCC is a revolutionary design with great potentials in smart and sustainable energy devices."
