Science & Technology: New Drilling Technology Expands Engineered Geothermal Reservoirs in Hard Deep Rocks

Boring technology makes for deeper and safer wells (Science Business)

A patent-pending technology developed at ETH Zurich could make for more efficient fracture networks in deep gas, oil and geothermal wells.

Thermal borehole enlargement through thermal spallation can be used to bore deep wells for gas, oil or geothermal exploitation in hard rock. It could also boost the efficiency of new wells and recovery of abandoned wells.

The shape of the borehole can be optimised in order to enhance the subsequent stimulation process.

The creation of deep reservoirs for gas, oil and geothermal energy extraction is impeded by insufficient stimulation. Direction and extension of the created fractures are complex to control and, therefore, large stimulated and interconnected fracture networks are difficult to create.

In order to reduce the project failure risks and increase the reservoir productivity, we developed a technology to control the creation of engineered reservoirs in hard deep rocks.

USA: Geothermal Steam to Provide 4,960 MW Generating Capacity by 2021 - FERC

98% of new U.S. electrical generation in January and February came from wind and solar power (Solar Power World)

Geothermal steam provides 3,830 MW and will add another 1,130 MW by 2021.

U.S. Federal Energy Regulatory Commission (FERC)’s latest Energy Infrastructure Update (with summary statistics for January and February 2018) also reveals that the total installed capacity of renewable energy sources now provides over one-fifth (20.39%) of total available U.S. generating capacity. Combined, wind and solar alone exceed one-tenth (10.18%) of installed capacity–a share greater than either nuclear power (9.11%), hydropower (8.49%) or oil (3.64%). Geothermal steam provides 0.32% of total generating capacity with 3.83 GW.

The report also estimates proposed Generation Additions and Retirements by March 2021. Geothermal Steam is proposed to add 24 units for an additional  1,130 MW of capacity.

USA: Call for Rejection of RD&D Budget Cuts for Geothermal Technologies

Federal Energy RD&D: Building on Momentum in Fiscal Year 2019 (Information Technology & Innovation Foundation)

In this report, we first describe the key role of the federal government in the U.S. energy innovation system. We then provide a high-level overview of both DOE’s overall budget and its RD&D budget. The bulk of the report drills down into the programs and subprograms that make up DOE’s RD&D budget, detailing what would be put at risk by the administration’s proposal, and opportunities that might be realized through its expansion. The following is an excerpt from the sub-report on Federal Energy R&D: Geothermal Technologies:

In addition to the current U.S. installed capacity of geothermal energy of over 3.8
gigawatts (GW), there is a vast source of untapped energy just waiting to be realized: an estimated 30 GW of hydrothermal plus more than 100 GW of geothermal energy through EGS. The geothermal industry operates in a harsh subsurface environment in which unique technical and operational challenges must be overcome to realize this potential.

Foremost among these challenges is the resources essentially being “out of sight” at a depth of anywhere from two to five kilometers, thus requiring new exploration technologies and tools to reduce the near-term cost and risk of development. DOE has set an ambitious goal of reducing the cost of electricity from newly developed geothermal systems from 22.4 cents per kilowatt-hour ($0.224/kWh) in 2014 to $0.06/kWh by 2030. Meeting this target (for both hydrothermal and EGS resources) requires R&D to harness lower-temperature
resources more effectively, develop improved methods to stimulate new EGS resources, and characterize and model subsurface stress and other reservoir properties. Reductions in R&D funding threaten to delay or even derail the progress DOE has already made toward these targets.


USA: Funding Opportunity for Advancing Geothermal Drilling Technologies

Department of Energy Announces $14.5 Million to Advance Geothermal Drilling Technologies (News Release)

Today, the U.S. Department of Energy (DOE) announced up to $14.5 million in new funding to advance geothermal energy development. The Efficient Drilling for Geothermal Energy (EDGE) funding opportunity announcement (FOA) will focus on geothermal drilling in support of accelerating the research and development of innovative geothermal energy technologies in America.

“Advancing research in geothermal drilling technologies will help harness the heat beneath our feet to expand our domestic energy resources,” said Daniel Simmons, Principal Deputy Assistant Secretary for Energy Efficiency and Renewable Energy. “Geothermal is a reliable, baseload renewable energy source with firm and flexible operation, allowing it to provide a range of essential services that contribute to our nation’s grid stability and resiliency.”

Geothermal energy represents a clean, efficient, and nearly inexhaustible domestic energy resource. The U.S. currently has an installed geothermal capacity of more than 3.8 gigawatts (GW), and there is an estimated 100 GW or more of additional potential geothermal development accessible in undiscovered hydrothermal and enhanced geothermal systems. Technological innovation is necessary to economically convert these resources into cost-effective energy services. DOE’s Geothermal Technologies Office (GTO) supports early-stage research and development (R&D) to achieve these necessary technological breakthroughs.

The EDGE FOA aims to continue and expand GTO’s R&D in geothermal drilling by covering three topic areas:
  • Topic Area 1 focuses on early-stage R&D projects to reduce common delays in drilling operations like lost circulation, stuck pipe, unstable wellbores, and other issues that take time away from deepening the hole, typically referred to as non-drilling time.
  • Topic Area 2 focuses on early-stage R&D projects in innovative drilling technologies that improve the rates of penetration for drilling geothermal wells.
  • Topic Area 3 focuses on exploring innovative approaches and models to accelerate the transfer of geothermal drilling and related technologies from the laboratory into the real world by focusing on building partnerships that will increase adoption of nascent technology and improving knowledge transfer in the geothermal industry. 
The application process will include two phases: a Concept Paper phase and a Full Application phase. Applicants must first submit a Concept Paper by 5 PM ET on May 31, 2018 to be eligible to submit a Full Application.

More information on the EDGE FOA can be found on the EERE Funding Opportunity Exchange. For more information on the Geothermal Technologies Office, visit their website HERE.

United Kingdom: Deep Geothermal Potential of the UK

Keeping warm: deep geothermal potential of the UK (EPSRC)

Jon Gluyas and Charlotte Adams discuss  recent National Centre for Energy Systems Integration (CESI) research which looks at how the UK’s heat supply can be decarbonized and national energy security improved.

Two recent papers to emerge from CESI examine the potential to decarbonize the UK’s heat supply and simultaneously improve national energy security.

The article by Gluyas et al on ‘Keeping warm: a review of deep geothermal potential of the UK’ examines how much heat could be extracted from sedimentary basins and granite bodies while Adams and Gluyas article on ‘We could use old coal mines to decarbonize heat – here’s how’ looked at the resource potential of ultra-low enthalpy heat in abandoned flooded coal mines. 

A very conservative estimation indicates that at current levels of heat use there is an absolute minimum of 100 years heat supply from these sources. Moreover, such heat sources have a near zero carbon footprint.

Kenya: Geothermal Fills the Gap as Hydropower Becomes More Intermittent

As drought saps hydropower, steam may keep Kenya boiling along (The Star, Kenya)

In February, Kenyans awoke to news that has become an annual ritual: Authorities were considering temporarily shutting down hydropower dams, the country’s largest source of electricity.

The reason was the one given each dry season for the last four years – too long without rain had left too little water in reservoirs to turn the turbines and generate power.

Kenya Power, the national electricity utility, has so far always managed to avoid a full shutdown, instead turning off just a few turbines at a time. But to make up the gap it has turned to more expensive – and polluting – diesel generators to keep the country plugged in.

Now, however, another clean source of power may help fill the gap: Geothermal power.

Science & Technology: Better Location of Boreholes Helps Geothermal Well Drilling

Optimized Positioning of Geothermal Boreholes Reduces Seismicity (Karlsruhe Institute of Technology)

When constructing geothermal systems for the extraction of heat from underground hot water reservoirs, optimal positioning of the boreholes can considerably reduce seismicity. This is the result of induced seismicity studies by scientists of Karlsruhe Institute of Technology (KIT)

Induced seismicity means shocks caused by human activities. Based on the change of water pressure in the rock (pore pressure) and the mechanical stresses in the rock, the researchers modeled changes of the stress field as a result of the injection and extraction of fluids, e.g. gases or liquids.

Norway: Company Provides Equipment that Can Withstand the Most Extreme Geothermal Conditions

Measuring devices for the world’s most extreme environment (News Release)

Norwegian research scientists are contributing to the development of the world’s hottest geothermal well in a non-volcanic area. The goal is to exploit the inexhaustible supply of heat from the interior of the Earth, and this calls for equipment that can withstand the most extreme conditions.

An international research team recently completed a three-year EU project called DESCRAMBLE (Drilling in dEep, Super-CRitical, AMbients of continentaL Europe). Together, the project team has drilled a test well in a geothermal field in Tuscany in Italy. The Italian company Enel Green Power, a global producer of green energy, is heading the project, with SINTEF, one of Europe’s largest independent research organisations, as its research partner. Together they are attempting to harness the natural forces found three kilometres closer to the Earth’s core.

The measuring equipment SINTEF has developed as part of this project is a so-called “wireline logging tool” that can measure downhole temperatures and pressures. Such measurements are crucial in the search for the extremely energy-rich supercritical water. Temperature and pressure data indicate when the drill bit has entered a zone containing such water, and the well’s geothermal properties (both the maximum temperature and temperature changes caused by drilling) will tell us how much energy the well can produce.

Netherlands: 60-63°C Geothermal Waters from 2,114 Meter Deep Well to Heat Dutch Greenhouses

Züblin Spezialtiefbau schließt zwei geothermische Tiefbohrungen in den Niederlanden erfolgreich ab - Züblin Spezialtiefbau successfully completes two geothermal deep wells in the Netherlands (Strabag)

The production well was drilled up to 2,114 meters vertical depth and the injection well drilled to 1,859 meters vertical depth.

Die Pumpversuche erbrachten mit Förderraten von bis zu 400 m³/h bei Thermalwassertemperaturen von 60-63°C den Nachweis eines sehr potenten geothermischen Reservoirs, welches mit Fertigstellung der Heizzentrale und eines Zwischenspeichers Anfang 2018 an ein bestehendes Nahwärmenetz angeschlossen wurde.

Durch das Anschließen der geothermischen Heizzentrale an das Wärmenetz eines niederländischen Energieproduzenten können die Pflanzen-Setzlinge in den Gewächshäusern CO2-neutral gezüchtet werden. Geplant ist die Nutzung des Wärmenetzes von Wayland Energy für insgesamt 15 Gewächshäuser in Bergschenhoek und Bleiswijk.

(From Google Translate) With pumping rates of up to 400 m³/h and thermal water temperatures of 60-63°C, the pumping tests provided proof of a very potent geothermal reservoir, which was connected to an existing local heating network at the beginning of 2018 with the completion of the heating system and a buffer.

By connecting the geothermal heating center to the heating network of a Dutch energy producer, the plant seedlings in the greenhouses can be grown CO2-neutral. The plan is to use Wayland Energy's heating network for a total of 15 greenhouses in Bergschenhoek and Bleiswijk.

First it was the Celts, who worshipped at the waters bubbling up from beneath the surface of the earth, then the Romans, who created a complex of baths and steam rooms to harness the power of the sacred springs.

Now 21st century engineers are to use the water from the same hot springs beneath the city of Bath to heat its medieval abbey.

Builders will shortly begin work on an underfloor heating system using the waters from the springs which supply the historic Roman baths.

The scheme, being funded by the Heritage Lottery Fund, envisages 1.5 megawatts of continuous energy being produced, enough to heat the church and surrounding buildings, as well as the Romans Baths and Pump Room complex itself.

The REmap Case 2050 target for geothermal energy is 227 GW

Renewable energy needs to be scaled up at least six times faster for the world to meet the decarbonisation and climate mitigation goals set out in the Paris Agreement, says Global Energy Transformation: A Roadmap to 2050.

The total share of renewable energy must rise from around 18% of total final energy consumption (in 2015) to around two-thirds by 2050. Over the same period, the share of renewables in the power sector would increase from around one-quarter to 85%, mostly through growth in solar and wind power generation.

Finance: Report Identifies Key Barriers and Highlights Policy Options to Boost Geothermal Energy Deployment

Renewable Energy Policies in a Time of Transition (IRENA)

This report, prepared jointly by the International Renewable Energy Agency (IRENA), the International Energy Agency (International Energy Agency (IEA) and the Renewable Energy Policy Network for the 21st Century (REN21), identifies key barriers and highlights policy options to boost renewable energy deployment.

After reviewing current policies and targets worldwide, it examines sector-specific policies for heating and cooling, transport and power, as well as measures for integrating variable renewables. An updated policy classification and terminology list can serve as a global reference for renewable energy policy instruments.

Supporting Geothermal Power by Reducing Risk

Global potential for geothermal energy is estimated at 70 to 80 GW. However, because of several barriers, only 15% of the potential capacity is being harnessed globally. One key challenge relates to the high risks and upfront costs associated with exploration, as well as overall project development costs, which occur over a relatively longer period of time.

To reduce the risks associated with geothermal development, several policy approaches and instruments have been successfully applied globally, including: full government development of the resource; cost-sharing between the government or donors and the private sector to mitigate risk; use of insurance instruments and loan guarantees; and application of other fiscal incentives (e.g. tax and import duty exemptions). Key features enabling successful implementation of geothermal projects under various policies include: sufficient capacity within the private sector to implement projects through a multistage (and time-consuming) process; development of transparent and clear criteria to select project development partners; and provision of clear information
on risk capital to be mobilised.

Kenya, Turkey and Nicaragua have been successful in reducing risk through government-supported early-stage drilling with project development undertaken by the private sector. The Geothermal Risk Mitigation Funds for Africa and the Geothermal Development Facility for Latin America are supported by several
donors and providing co-funding for early-stage exploration and certain project development costs. The facility also provides further risk mitigation through allowing for conversion of the co-funding into a full grant (with no further financial obligation) in cases where drilling is unsuccessful.

Italy: Enel Announces Award for Mercury and Sulphurized Hydrogen Reduction System for Geothermal Power Plants

Geothermal: Innovation Comes from an Alliance between Business and Research (News Release)

A winner has been chosen for the challenge launched by Enel Green Power to identify innovative solutions to use at geothermal plants. The winner of the 15,000-euro prize is Luigia Lona, a researcher-entrepreneur with “an innate instinct to search for solutions”.

“An innate instinct to search for solutions” and the belief that “true, effective innovation comes from the close relationship between research, application and business”. These are the two key factors that inspired Luigia Lona to participate in and win the challenge launched by Enel Green Power to make Mercury and Sulferized Hydrogen Reduction (AMIS) systems in EGP geothermal plants more effective.

The winning idea involved a change in the last stage of the AMIS cycle, where soda is used to regulate the level of acidity in the liquid solution coming from the H2S reduction process. Specifically, the change involves halving the entry of soda in the scrubber and introducing a system that allows for the optimisation of the quantity of soda consumed for different sections.

Finance: Geothermal Energy Favors Well in External Cost Comparison

Accounting for The Full Cost of Electricity (News Release)

The market price of generating electricity doesn't necessarily account for the social and environmental impacts of its generation, says the Organisation for Economic Co‑operation and Development Nuclear Energy Agency (NEA) in its new report The Full Costs of Electricity Provision.

"What this report reveals is that the notion of "electricity cost" that we often use today, the levelised costs of electricity (LCOE), is just a part of a much bigger picture. While LCOE is a useful tool to compare the costs of baseload technologies in regulated systems, it leaves out many decisive aspects of the costs of electricity. In particular, the grid‑level system costs and the social costs that are not captured by LCOE are too important to be ignored any longer" said NEA Director‑General William D. Magwood, IV, at the report's launch.

Indonesia: PT Supreme Energy Boss Reaffirms Commitment to Geothermal Energy Projects

Supramu Santoso: It’s Challenging, but We Stick in Geothermal (TheInsiderStories)

TheInsiderStories interviews President and CEO of PT Supreme Energy Supramu Santoso.

Q: How is the progress of Supreme’s Business? We will start the construction of geothermal plants in June this year and targets the operation in 2020. It takes around three years. The project capacity is 91 megawatt.

Q: It is your first project? No, we earlier drilled some geothermal wells, but we should continue to drill around 13 wells. We currently have three geothermal concession in West Sumatra, South Sumatra, and Lampung.

Q: How much is the potential power capacity of the project? Around 80 megawatts in West Sumatra project.

Q: How about the other projects? In South Sumatra project, we will start drilling in July this year. For Lampung project, we hope we can build a road to the project this year.

Q: How much is the total capacity of the project? We do not know. It depends on. It is difficult to estimate. In the past, we expected around 600 megawatts for the three projects but the exploration result is different. So we do not dare to estimate, we hope to discover around 200 megawatts.

Q: Do you have a project that already in production phase? The West Sumatra project will (come) on stream on 2019, (with) approximately 86 megawatt of gross production.

Q: The renewables business faced many obstacles, but are your company stick in this industry? When we first entered the geothermal industry, it was very promising. The energy demand projected to grow around 9% per year while the oil and gas production dropped. In addition, Indonesia has huge geothermal sources. So, I was thinking that it’s a good investment, but it is not easy.
