Germany: Vulcan Plans New Geothermal Power Plant for Lithium Extraction Demonstration Project

Positive Scoping Study Confirms Potential for Major European Zero Carbon Lithium™ Project (News Release)

Highlights:
  • Scoping Study for Vulcan’s Zero Carbon Lithium™ Project demonstrates the potential for a combined operation producing lithium hydroxide and renewable energy, with net zero carbon footprint.
  • The Scoping Study is based on a staged expansion plan:
    • Stage 1: Construction and operation of Direct Lithium Extraction (DLE) and lithium hydroxide plant at an operating, producing geothermal well and power plant, and;
    • Stage 2: Drilling ten new geothermal production wells, construction of new, combined geothermal, DLE and lithium hydroxide plant at Vulcan’s 100 %-owned Ortenau license.
A geothermal power plant and wells already exist for Stage One, at the Insheim Plant, therefore no geothermal process design is required. For Stage Two, details of plant design are provided below to inform the reader of the material factors around geothermal plant development.

The Stage Two Geothermal Power Plant is responsible for four main functions; receiving brine from all geothermal production wells to generate power from ORC units, reduce the temperature of the brine to levels adequate for the lithium extraction circuit, generate steam for use in the Li product dryer (only in the four well plant) and to reinject the brine with any NCGs produced. Scaling prevention is also an important component of the process design. Based on references from other facilities, 50 µm filters are used on both the production and reinjection lines to prevent clogging of fractures within the reservoir with fine particles. Additionally, scaling inhibitors are injected into the brine stream to reduce scaling on equipment, most notably to reduce cleaning frequency of heat exchangers.

Europe: Project Launched to Study Behaviour of Geothermal Fluids to Increase Efficiency of Geothermal Operations

From react to REFLECT: new EU research project will study behaviour
of geothermal fluids to increase efficiency of geothermal operations (News Release)

The efficiency of geothermal utilisation largely depends on the behaviour of  fluids that transfer heat between the geosphere and the engineered components of a power plant.

The EU-funded REFLECT project aims to avoid problems related to fluid chemistry rather than treat them. These physical and chemical properties are often poorly defined, as in situ sampling and measurements at extreme conditions are difficult to date. Therefore, large uncertainties in current model predictions prevail, which will be tackled in REFLECT by collecting new, high-quality data in critical areas.

This data will be implemented in a European geothermal fluid atlas and predictive models allowing to provide recommendations on how to best operate geothermal systems for a sustainable use.

REFLECT recently marked its start with the kick-off meeting held on 29 and 30 January 2020 at the premises of the coordinator, the Helmholtz Zentrum Potsdam Deutsches Geoforschungszentrum (GFZ) based in Potsdam, Germany. The consortium as a whole consists of 14 partners from nine different European countries including three research institutes and geological surveys, one European organisation, four universities, and three companies.

Indonesia: Masters Thesis on the Lahendong Geothermal System in North Sulawesi

MSc Thesis: The dynamic evolution of geothermal system in Lahendong, North Sulawesi, Indonesia (Iceland School of Energy)

MSc in Sustainable Energy candidate, Lily Suherlina, successfully defended her master's thesis where she investigated the dynamic evolution of the Lahendong geothermal system in North Sulawesi, Indonesia.

Lily's study discussed integrated approaches to characterising dynamical evolution of the exploited high-enthalpy geothermal system of Lahendong, North-Sulawesi, Indonesia. As she explains, Lahendong has two primary reservoirs, the southern and the northern. Lily's main focus was characterisation of detailed fluid dynamics in the system with respect to geological structures and permeability distribution. Her approach combine integrated analysis of well data and detailed hydrochemical analysis to understand how the geothermal system evolves and the distribution of changes due to structural influence and prolonged exploitation of the reservoirs.

India: Pilot 20 kW Geothermal Power Project Advances in Telangana

SCCL, TSGenco to tap geothermal energy (Deccan Chronicle)

Efforts are on by Singareni Collieries Company Limited (SCCL) and TSGenco to tap geothermal energy from the hot water springs in the forests around Pagideru and Khammamthogu villages in Pinapaka assembly constituency of Bhadradri-Kothagudem district.

To tap the geothermal energy from hot water springs in Pagideru and Khammamthogu, wells are proposed to be dug a mile deep underground for accessing steam and hot water. These can be used to drive turbines connected to electricity generators.

Scientists of the Geological Survey of India have already conducted a survey and dug over 10 bore wells. They found plenty of hot water underground, which they feel can be tapped for producing geothermal energy. SCCL has come forward to invest in the project and T Genco will extend all technical support to it. SCCL will spend `1.5 crore to produce 20 kilowatt power on a pilot basis.

Kenya: Kengen Looks to Expand Geothermal Business Abroad

KenGen eyes geothermal tenders in 8 African states (Business Daily)

State-owned Kenya Electricity Generating Company (KenGen)  is eyeing lucrative geothermal infrastructure tenders in nine African countries, officials have said.

KenGen, which last October won a Sh5.2 billion tender to drill geothermal wells in Ethiopia, the second win in the landlocked country in under four months, said it is eyeing similar deals in Uganda, Tanzania, Djibouti, Rwanda, South Sudan, The Sudan, Zambia and Comoros to boost revenues.

“We have ready capacity to help these countries exploit their geothermal resources. We are already doing this for Ethiopia and we are in talks with these countries on how to collaborate with them,” said Cyrus Karingithi, the assistant manager, resource development and infrastructure at the KenGen in an interview with Business Daily.

Science & Technology: Offshore Carbon Capture and Storage Project Looks for Support

The Promise and Potential of Turning CO2 to Stone (Earth Institute)


Carbon capture and storage (CCS) technologies, which remove tons of carbon dioxide from industrial processes and store them away so they can’t add to the climate crisis, are gaining attention and support. A recent review paper details how CCS can contribute to a long-term reduction in atmospheric carbon dioxide levels, and work to meet the caps on human-caused global warming written into the 2015 Paris Climate Agreement.

Under an Iceland-based pilot project called CarbFix — designed and carried out with Columbia University leadership — researchers proved that basaltic rock units react rapidly with CO2 captured from a power plant. The team mixed gasses generated by the Hellisheidi geothermal power plant with water and reinjected the solution into the volcanic basalt below.

With the Solid Carbon project, the team aims to conduct offshore geophysical surveys, study the basalt reservoir, and set up a pilot injection and monitoring experiment at a site in Cascadia, at approximately the scale of the CarbFix project in Iceland.

Today’s announcement that the “Solid Carbon” capture and storage project has been selected by the MacArthur Foundation as one of the highest-scoring proposals in its 100&Change competition offers hope. As one of the top 100 projects, Solid Carbon will be featured in an online database of high-impact ideas. Goldberg hopes this will help to attract the support needed to fund a next-level carbon capture and storage demonstration. The program is designed to connect philanthropists with vetted, high-impact projects in need of funding.

Science & Technology: Geothermal Reservoir Stimulation Explained at the Espoo Geothermal Deep Heat Project

Seismic data collected around Otaniemi geothermal project enables earthquake science and explains (Mirage News)


In a paper published online in Seismological Research Letters on 5 February 2020 a team led by Seismologists from the Institute of Seismology at the University of Helsinki discusses observations obtained from a large network of seismic stations that was deployed during 2018 around the geothermal reservoir stimulation below the Aalto University campus in Otaniemi.

In June and July 2018 the operating St1 Deep Heat Oy company injected about 18,000 cubic meter of water at 6 km depth which caused many thousands of small earthquakes. The earthquake fractures reaching at most the meter scale underpin the concept of the Enhanced Geothermal System because they enable an efficient water circulation and thus heat exchange.

This uneven spatial distribution of the disturbances is controlled by the so-called source mechanism-the orientation of the activated fracture and the direction of the earthquake slip motion-of the largest earthquakes, which causes some areas to be more affected than others.

A second borehole is currently being drilled, and a smaller stimulation is planned for this spring to complete the circulation system. The plant is intended to operate for a few decades. Small earthquakes are expected during the forthcoming injection, and may also occur during later operating stages.

Science & Technology: Penetrating Rock at Faster Speeds, to Greater Depths, and at a Lower Cost than Conventional Drills

AltaRock Energy Melts Rock With Millimeter Waves for Geothermal Wells (IEEE Spectrum)

The Seattle-based company received an ARPA-E grant to test and scale its technology

A vast supply of heat lies beneath our feet. Yet today’s drilling methods can barely push through dense rocks and high-pressure conditions to reach it. A new generation of “enhanced” drilling systems aims to obliterate those barriers and unlock unprecedented supplies of geothermal energy.

AltaRock Energy is leading an effort to melt and vaporize rocks with millimeter waves. Instead of grinding away with mechanical drills, scientists use a gyrotron—a specialized high-frequency microwave-beam generator—to open holes in slabs of hard rock. The goal is to penetrate rock at faster speeds, to greater depths, and at a lower cost than conventional drills do.

The Seattle-based company recently received a US $3.9 million grant from the U.S. Department of Energy’s Advanced Research Projects Agency–Energy (ARPA-E). The three-year initiative will enable scientists to demonstrate the technology at increasingly larger scales, from burning through hand-size samples to room-size slabs. Project partners say they hope to start drilling in real-world test sites before the grant period ends in September 2022.

Indonesia: ADB Director Sees Promise for More Financing of Geothermal

Indonesia’s geothermal drive (The Oil & Gas Year)

Winfried Wicklein, country director for Indonesia at the Asian Development Bank (ADB), talks to TOGY about how Indonesia’s LNG and upstream opportunities can be made more attractive and prospects for its geothermal drive. ADB supports the energy industry in Indonesia by financing private-sector projects, working with PLN on power projects and engaging on policy and regulatory reform.

"ADB has supported the geothermal sector by funding projects such as the 330-MW Sarulla plant; the 80-MW Muara Laboh plant; and the 90-MW Rantau Dedap project, which was approved last year. We are also working with state-owned companies to ensure that Indonesia can develop all designated working areas as soon and effectively as possible.

Despite the general push for non-conventional energy, the geothermal sector has slowed down in the last 12-18 months. Here, pricing may be an important factor. Depending on location, current electricity pricing caps linked to the average generation cost would impact the financial viability of projects, especially in the renewable energy space.

However, we are seeing some promising developments on the financing front. For instance, PT SMI, with support from the World Bank and the Green Climate Fund, has launched a de-risking mechanism for geothermal projects which should help mitigate exploration risks."

Science & Technology: Flow Control Devices Helps in Mitigating Against Thermal Breakthrough in Geothermal Reservoirs

From Oil & Gas to Geothermal: flow control devices (Phoenix RDS)

Flow control devices (FCDs) or inflow control devices (ICDs) have been utilized for many years in well completions in the oil and gas industry. They are down hole tools or equipment designed to promote uniform flow in or out of a well by inducing pressure drop. Devices utilized in injection wells have been referred to as outflow control devices (OCDs) while those in production wells are referred to as inflow control devices (ICDs). FCDs have been successfully utilized in improving oil and gas production through secondary and tertiary recovery methods. They have been used in preventing water/gas breakthroughs. More recently they have been applied to Steam Assisted Gravity Drainage (SAGD) improving recovery in these reservoirs.

(A1) No Flow control –
inefficient zonal heat extraction
(A2) Flow control –
controlled, efficient zonal heat extraction
Reservoirs of hot water that exist at varying temperatures and depths below the Earth’s surface. These conventional systems are often referred to as hydrothermal systems and they naturally possesses all major components (heat >150C; fluid; and permeability) of geothermal systems. In these systems heat is transferred by convection. In these high temperature systems, injection flow control is an effective tool for reservoir management mitigating against thermal breakthrough and to increase productivity. Examples include a number of power plants throughout the Philippines including Gunung Salak, Mindanao, and Palinpinon. The application of FCD’s here can contribute greatly towards reservoir management increasing the longevity of the resource (See A1 & A2 above).

Science & Technology: Researchers Determine Potential for Occurrence of M > 2.0 Seismicity for Geothermal Operations in Sandstone Target Formations in the Netherlands is Low

Review of induced seismicity in geothermal systems worldwide and implications for geothermal systems in the Netherlands (Cambridge Core)


Here we review the occurrence (or the lack) of felt seismic events in geothermal systems worldwide and identify key factors influencing the occurrence and magnitude of these events. 

Based on this review, we project the findings for seismicity in geothermal systems to typical geothermal formations and future geothermal developments in the Netherlands. 

The case study review shows that doublets that circulate fluids through relatively shallow, porous, sedimentary aquifers far from the crystalline basement are unlikely to generate felt seismic events. On the other hand, stimulations or circulations in or near competent, fractured, basement rocks and production and reinjection operations in high-temperature geothermal fields are more prone to induce felt events, occasionally with magnitudes of M > 5.0. 

Many of these operations are situated in tectonically active areas, and stress and temperature changes may be large. The presence of large, optimally oriented and critically stressed faults increases the potential for induced seismicity. 

The insights from the case study review suggest that the potential for the occurrence of M > 2.0 seismicity for geothermal operations in several of the sandstone target formations in the Netherlands is low, especially if faults can be avoided. The potential for induced seismicity may be moderate for operations in faulted carbonate rocks. 

Induced seismicity always remains a complex and site-specific process with large unknowns, and can never be excluded entirely. However, assessing the potential for inducing felt seismic events can be improved by considering the relevant (site-specific) geological and operational key factors discussed in this article.

Science & Technology: Geothermal Drilling in Search of Supercritical Fluids - Looking for the Eureka Moment

Want Unlimited Clean Energy? Just Drill the World's Hottest Well (Wired)

Geothermal Sunset, by Fabio Sartori. GRC Photo Contest 2019.
Nuova Monterotondo geothermal power plant, Italy.
An engineering team bored 2 miles into hot rock without causing major earthquakes—a good sign for harnessing the Earth's heat as a power source.

There’s treasure buried deep beneath the viridescent foothills of Tuscany’s Apennine Mountains, where the stark metal trusses of the Venelle-2 drilling tower mark its location like an X on a map. This geothermal well reaches nearly two miles beneath the surface to a region where temperatures and pressures are so high that rock begins to bend.

Here, conditions are ripe for supercritical geothermal fluids, mineral-rich water that exhibits characteristics of both a liquid and a gas. It’s not exactly gold, but if Venelle-2 could tap into a reservoir of supercritical fluids and use them to spin a turbine on the surface, it would be one of the most energy-dense forms of renewable power in the world.

Drilling at Venelle-2 stopped just shy of the K horizon when temperatures at the bottom of the well overwhelmed the equipment. Sensors at the bottom of the well indicated temperatures had breached 1,000 degrees Fahrenheit and pressures 300 times greater than at the surface. Nevertheless, Venelle-2 is the hottest borehole ever created, and it demonstrated that it's possible to drill at the extreme end of supercritical conditions.

To achieve its capacity expansion plans, KenGen is working in close collaboration with the National Treasury to develop a 140 MW greenfield geothermal power plant through a Public Private Partnership (PPP). Kenya approved a framework for developing and implementing infrastructure PPPs under the PPP Act of 2013 which led to the promulgation of PPP regulations in 2014.

The Olkaria geothermal field is in Naivasha, approximately 120 km northwest of Nairobi. The Project area is in the northeastern sector of the Olkaria geothermal field. The power plant location is next to the existing Olkaria II power station and will interconnect to the grid at the Olkaria I AU switchyard. The site is within an area leased by KenGen from the Kenya Wildlife Service.

The Project will consist of a geothermal power generating facility and associated interconnection facilities with a capacity of approximately 140 MW at site reference conditions, to be specified in detail within the RFP.

Taiwan: Potential for 32 GW of Geothermal Capacity

Taiwan’s Alternative Energy Options (Taiwan Business Topics)

A geothermal power plant operates similarly to a nuclear or coal-fired steam generator but with magma buried deep beneath the earth’s surface as its heat source. Unlike intermittent wind or solar resources, geothermal power can operate continuously and serve as baseload power. However, geothermal reservoirs are accessible from only a small portion of the earth’s surface.

Located along the seismically active Pacific Ring of Fire and replete with hot springs, Taiwan would seem a likely candidate for geothermal power development. The island has a long history of exploring geothermal power, having first considered its potential in the 1970s during the two international oil crises. But while such other countries as New Zealand and the Philippines took firm measures to develop the sector, Taiwan opted for nuclear power instead, largely abandoning geothermal.

Geologic surveys conducted by the government over the years have found that the geothermal potential in Taiwan could be as high as 32 gigawatts (GW) of installed capacity, which would be sufficient to supply most of Taiwan’s power needs. The administration’s goal for geothermal is modest, though. It plans to have only 200 megawatts (MW) of capacity in place by 2025 – less than 1% of the total renewable power target.

USA: No Major U.S. Geothermal Plant was Commissioned in 2019 - Factbook

2010s Deliver Decade of Clean Energy (BCSE)

An era of economic growth, reduced CO2 emissions and sharply falling energy costs for consumers

Over the past 10 extraordinary years, the United States has fundamentally overhauled how it produces, delivers and consumes energy. The 2020 edition of the Sustainable Energy in America Factbook – produced for the Business Council for Sustainable Energy by BloombergNEF, looks at the U.S. energy transformation of the past decade (2010 – 2019) and provides the annual update on the progress of energy efficiency, natural gas and renewable energy sectors in 2019 in America.
  • No major U.S. geothermal plant was commissioned in 2019. Unlike other renewable resources, geothermal projects have long project completion periods of 4-7 years. In addition, the technology lacks strong policy support and faces high development costs. These factors contributed to the low build volumes.
  • One geothermal plant currently sits in the EIA build queue. The 25 MW summer capacity Dixie Valley Power Partnership is currently slated to come online in Nevada in 2020. The plant is owned by AES and the company intends to sell power from the project into the California market.
  • The 2.9 MW of the Soda Lake Geothermal project in Churchill, Nevada was retired in 2019.
