United Kingdom: Good Explanation of Drilling Trajectories at United Downs Deep Geothermal Power Project

United Downs Deep Geothermal Power Project - Update‏ (UDDGP)

Once the 9 5/8” casing is cemented in place, we will reconfigure the wellhead and BOP and continue drilling, this time at a diameter of 8 ½”. Drilling will continue for another 1,000m approximately, but this will depend on exactly where we intersect the target fault structure. As soon as we are sure we have drilled through it, we will stop, run further geophysical logs and then conduct a short production test. That will complete the activity on UD-1, so then we will move the rig 8m along the site and start drilling UD-2. The slower than expected drilling speeds means that we are behind our original schedule and we now expect to finish UD-2 at the end of June.

A word about depth…

Now that we are getting towards the business end of our first well, we thought it would be worthwhile explaining something about how we report depths.

We always talk about the wells being 2,500m and 4,500m deep but actually that’s a kind of shorthand. They are the target ‘true vertical depths’ (TVD) at which we plan to intersect the eastern edge of the Porthtowan Fault Zone. The wells will continue through the fault zone and therefore finish up being quite a bit deeper.

There is also a difference between TVD and ‘measured depth’ (MD) which is the drilled length of the wells. They are not the same thing because the wells aren’t vertical. All our progress reporting is based on MD. As we get deeper, and the wells get further away from being vertical, there will be an increasing difference between MD and TVD.  The TVD will always be less than MD.

The exact final depth of UD-1 will depend on where we hit the fault and how thick it turns out to be but we expect the well to end up with a measured depth of about 5,500m and a true vertical depth of about 5,300m.

Science & Technology: Increasing the Heat Extraction Efficiency of Enhanced Geothermal Systems

Effect of different flow schemes on heat recovery from Enhanced Geothermal Systems (EGS) (Science Direct)

By Pranay Asai, Palash Panja, John McLennan and Milind Deo. Department of Chemical Engineering, University of Utah, United States

Operational optimization is the key to maximize the heat extraction efficiency of Enhanced Geothermal Systems (EGS). Injection/production flowrate is one of the operational parameters that can be easily manipulated to produce desired amount of energy.

In this study, the effect of different flow schemes on the rate of heat production is analyzed over a period of 30 years. Seven flow schemes (four continuous functions namely constant flow, linear flow, exponential flow, mirror exponential flow, and three step functions with step sizes of six months, three years and ten years) developed on the basis of mathematical functions were examined.

A doublet EGS model with a single fracture was simulated using a commercial thermal reservoir simulator. The reservoir and well data were obtained from the FORGE (Frontier Observatory for Research in Geothermal Energy) site at Milford Utah. The results were analyzed on the basis of their temperature decline curves for the produced water and the total amount of heat extracted over the entire period.

The exponential flow scheme is the optimum case considering the rise in energy demand over the next 30 years. The amount of heat extracted per unit volume of water decreases with increase in total water volume circulated.

New Zealand: Geothermal Energy Helps to Increase Renewable Share of generation

New Zealand Energy Quarterly (Ministry of Business, Innovation and Employment)

Despite the increase in coal-fired generation, the overall renewable share of generation rose from 81.9 per cent in the December 2017 quarter to 84.5 per cent in the December 2018. This was largely as a result of higher geothermal generation. In 2018 geothermal energy generated 7,377 GWh of electricity.

Geothermal generation has, for a long time, been an integral part of New Zealand’s electricity landscape. It began over 55 years ago with the opening of the Wairakei power station in November 1958. Most of New Zealand’s installed capacity is situated in the Taupo Volcanic Zone. Geothermal generation is around 15% of New Zealand’s electricity generation. Energy Quarterly: 2018 Q4 report [PDF, 82 KB]

USA, Utah: “The Best Hippie Hot Springs in the West”

How one man turned a geothermal wonder into a steamy, post-Woodstock paradise (Roadtrippers )

The '70s are alive and groovy as ever at Mystic Hot Springs in Utah

Back in the 1800s, long before hordes of VW bus owners set off on adventures of self-discovery, this geothermally rich destination was already bringing the heat. Guests from all over the valley and beyond would travel by horse and buggy to dance and soak all through the night. Earlier still, nomadic bands from the Ute, Shoshone, and Paiute tribes would make use of the warm grounds near the springs, setting up their camps here as they passed through. 

The bathtubs were some of the first additions Mike made when he acquired the property in 1996—but they’re still relatively new, considering that the hot springs first formed out of geologic events dating back millennia. 

The unique reddish-brown travertine mounds that can be seen throughout the hot springs, most notably around the tubs, are the results of minerals that have built up after being deposited inch by inch via the constant flow of water.

Water comes out of the ground at a piping hot 168 degrees Fahrenheit (75.5 degrees celsius) and a rate of 200 gallons per minute. The water eventually cools as it works it way through a network of channels and cascades into the pools and tubs. The minerals carried in this water—calcium carbonate, magnesium, and iron among them—are celebrated for their healing and relaxation properties, all part of the draw that’s been enticing visitors for centuries.

USA: Opportunity for Funding of Research on Subsurface Stress and Lost Circulation in Geothermal Drilling

Energy Department Announces $7 Million for Research on Subsurface Stress and Lost Circulation in Geothermal Drilling (EERE/GTO)

Applicants must first submit a concept paper by April 26, 2019 at 5 p.m. EST to be eligible to submit a full application. 

Today, the U.S. Department of Energy (DOE) announced up to $7 million toward the research and development (R&D) of innovative subsurface geothermal technologies. DOE’s Geothermal Technologies Office (GTO) will fund projects that will focus on improving geothermal drilling efficiency and cost reduction by addressing two of the most significant barriers: state of stress and lost circulation events.

The subsurface state of stress dictates fracture networks that provide the required permeability for a geothermal reservoir, so an increased understanding of the stress state is valuable for siting wells during geothermal energy development. Lost circulation events (LCEs) can occur during drilling when fluids pumped from the rig through downhole drilling equipment are “lost” and flow into geological formations instead of returning to the surface to complete a circulation path. Researching and developing innovative technologies that tackle state of stress and LCEs issues will reduce geothermal exploration and drilling costs, making geothermal a more viable and accessible energy source.

Currently, the United States is the world leader in installed geothermal capacity with more than 3.8 gigawatts online. One key to unlocking domestic geothermal potential is to reduce the cost of drilling operations, which can account for up to 50% of geothermal exploration and development costs.

GTO plans to provide funding in two topic areas:
  • Topic 1: Development of technologies for characterizing, monitoring, and predicting state of stress for geothermal exploration and drilling; and
  • Topic 2: Development of new technologies for predicting and mitigating lost circulation events in geothermal drilling.
Applicants must first submit a concept paper by April 26, 2019 at 5 p.m. EST to be eligible to submit a full application. Please view the FOA and application submission instructions for more information.

Finance: Investment Management Company Raises More Funds for Renewable Energy

Meridiam announces the closing of the reopening of its Africa fund at €546 million, 2.5 times its initial size (News Release)

European  investment management company Meridiam announced today the closing of the reopening of its Meridiam Infrastructure Africa Fund (MIAF) for a total amount of €546 million, above its initial target of €510 million. Launched in 2015, for an initial amount of €207 million, the initial commitment has already been fully invested two years before the end of the investment period. At the end of this closing, it is now 2.5 times bigger than at the beginning. 

This fund has already financed and developed 14 major projects for Africa amounting to more than EUR 3 billion, including the Tulu Moye geothermal power plant. With a final capacity of 500 MW, it is the first Independent Power Producer (IPP) in Ethiopia. 

Finance: Corporate Giants Band Together to Buy Renewable Energy

Google, GM and other corporate giants form alliance to create a boom in US clean energy (CNBC)

Some of the nation's top tech firms, manufacturers and consumer companies are banding together to create a boom in renewable energy purchases throughout corporate America.

The corporate giants and their nonprofit partners on Thursday launched the Renewable Energy Buyers Alliance (REBA), a trade organization that will help companies take advantage of new ways to purchase clean energy. The goal is to support construction of new green power projects by striking renewable energy deals pioneered by companies like Google-parent Alphabet, General Motors and Walmart in recent years.

Under the banner of REBA, these pioneers aim to empower tens of thousands of companies to buy renewable energy in the coming years — increasing the market from roughly 5,000 companies today.

Through last year, companies signed enough corporate renewable deals to support nearly 16 gigawatts of new renewable energy capacity in the U.S. REBA aims to accelerate that activity and grow the market to 60 gigawatts by 2025.

Science & Technology: Model for Optimizing Production from a Geothermal Two-Phase Reservoir

Study of Production-Injection Strategies for Sustainable Production In Geothermal Reservoir Two-Phase by Numerical Simulation (ITB)

by Nenny Miryani Saptadji and Heru Berian Pratama. Geothermal Engineering Study Program, Institut Teknologi Bandung, Indonesia.

The main issue in the management of the two-phase liquid-dominated geothermal field is a rapid pressure decline in the reservoir which affects steam supply to the power plant.

The changes of reservoir characteristic due to mass and heat extraction from the reservoir can be learned through a numerical simulation under numerous strategies production-injection. The model developed on liquid-dominated geothermal fields are assessed with various scenarios of production strategies (steam cap, brine reservoir, and combination) and injection strategies (deep, shallow, centered and dispersed), for generation of 110 MW and 220 MW using separated steam cycle.

A full factorial scenario of 32 production-injection strategies has been successfully carried out. The results show a relatively low decrease in reservoir pressure and steam flow rate for a production strategy combined with the steam cap and brine reservoir, with deep and dispersed injection strategy.

From the simulation, it can be concluded that the strategy for sustainable production is a production of 25% from steam cap and 75% from brine reservoir, dispersed and deep reinjection with 9 make-up wells from the steam cap. The implementation of production-injection strategy needs to be planned right from the beginning of exploitation, therefore, the strategy can adapt to changes in reservoir characteristics.

Finance: Batteries Co-located with Solar or Wind Projects are Starting to be Competitive

Battery Power’s Latest Plunge in Costs Threatens Coal, Gas (BNEF)

Two technologies that were immature and expensive only a few years ago but are now at the center of the unfolding low-carbon energy transition have seen spectacular gains in cost-competitiveness in the last year.

The latest analysis by research company BloombergNEF (BNEF) shows that the benchmark levelized cost of electricity,[1] or LCOE, for lithium-ion batteries has fallen 35% to $187 per megawatt-hour since the first half of 2018. Meanwhile, the benchmark LCOE for offshore wind has tumbled by 24%.

Batteries co-located with solar or wind projects are starting to compete, in many markets and without subsidy, with coal- and gas-fired generation for the provision of ‘dispatchable power’ that can be delivered whenever the grid needs it (as opposed to only when the wind is blowing, or the sun is shining).

Electricity demand is subject to pronounced peaks and lows inter-day. Meeting the peaks has previously been the preserve of technologies such as open-cycle gas turbines and gas reciprocating engines, but these are now facing competition from batteries with anything from one to four hours of energy storage, according to the report.

Science & Technology: Using Electric Plasma Bursts to Increase Rate of Penetration in Geothermal Drilling

Mechanical engineering researchers receive federal grant to enhance geothermal energy (Texas A&M University College of Engineering)

One remaining challenge associated with drilling geothermal wells is the presence of hard rocks, such as granite, that slow down the process and wear down drill bits. In turn, this causes drilling time and expenses to increase.

To combat this, a team of researchers from the J. Mike Walker '66 Department of Mechanical Engineering at Texas A&M University is developing Shockwave and Plasma Accelerated Rock Cracking (SPARC) drilling technology. By making the creation of wells more efficient, accessible and cost effective, their U.S. Department of Energy funded project will help make geothermal energy a more viable alternative to fossil fuels.

According to Dr. David Staack, associate professor, Sallie and Don Davis ’61 Career Development Professor, and College of Engineering director of laboratory instruction, the team’s SPARC technology will equip traditional drill bits with high voltage electrodes on the tip that emit a microscopic plasma discharge to shock the rock and crack it like a tiny explosion. Creating fractures and weakening the rock will allow the drill head, affixed with conventional diamond cutters, to have an easier time breaking through the material.

As Dr. Alan Palazzolo described, along with setting the stage for further development of geothermal energy, using electric plasma bursts to increase the rate of penetration will enable the drilling process to be streamlined and therefore be more cost competitive with nonrenewable resources.

Finance: Older Renewable Energy Facilities Can Be Ripe for Technology Upgrades

The Invisible Renewable Energy Revolution (#CleanTechnica Interview)

In Utah, the Cove Fort geothermal plant gets
a new life with hydroelectric additions 
CleanTechnica went to the BNEF Summit in New York on Monday and got the inside scoop on decarbonization from Mark McGrail, Associate VP of Energy Management at Enel Green Power North America (EGPNA).

McGrail had some interesting things to say about Enel’s recent headline-grabbing deal to purchase 620 megawatts of US renewable energy projects from GE.

The deal involves 7 solar and geothermal facilities that were already under a joint venture between GE and EGPNA. Many energy industry observers are scratching their heads over GE’s motivation to sell, though paying down debt is probably high on its list.

For EGPNA, part of the motivation to buy may be sole bragging rights to the innovative Stillwater geothermal plant.

As McGrail explained, the plant includes both a PV array and a concentrating solar field. The extra dose of solar power adds heat to the well, slows its degradation by smoothing out operational fluctuations, and stretches out its effective lifespan.

Another facility in the group of 7, the Cove Fort plant, also puts innovative technology to work with the aim of extending the lifespan of a geothermal well.

All of this is by way of saying that the US now has a fairly long roster of older renewable energy facilities that are ripe for technology upgrades that add capacity and/or improve lifespan. It’s like getting a whole new clean power plant, without having to develop a new site.

Climate Change: Increased Use of Renewables Have Great Impact on CO2 Emissions - IEA

Global Energy & CO2 Status Report (IEA)

The latest trends in energy and emissions in 2018

This online, annual report provides a snapshot of recent global trends and developments across fuels, renewable sources, and energy efficiency and carbon emissions, in 2018.

Renewables increased by 4% in 2018, accounting for almost one-quarter of global energy demand growth. The power sector led the gains, with renewables-based electricity generation increasing at its fastest pace this decade. Solar PV, hydropower, and wind each accounted for about a third of the growth, with bioenergy accounting for most of the rest. Renewables covered almost 45% of the world's electricity generation growth, now accounting for over 25% of global
power output.

Renewable electricity generated from other technologies grew by 7%, dominated by bioenergy. Geothermal electricity increased mostly in Turkey, with some gains also seen in Indonesia and the United States.

Increased use of renewables in 2018 had an even greater impact on CO2 emissions, avoiding 215 Mt of emissions, the vast majority of which is due to the transition to renewables in the power sector.

The savings from renewables was led by China and Europe, together contributing two-thirds to the global total. Increased generation from nuclear power plants also reduced emissions, averting nearly 60 Mt of CO2 emissions. Overall, without the transition to low-carbon sources of energy in 2018, emissions growth would have been 50% higher.

United Kingdom: Casing of Well at United Downs Deep Geothermal Project Completed to Nearly 4,000 Meters

United Downs Deep Geothermal Project - Update (GEL)

We completed installing and cementing the 9 5/8''casing (steel lining) to 3995m to isolate and seal this section last week and over the weekend. This was one of the most difficult parts of the project and was completed without a hitch; sighs of relief all round. We are now getting ready to drill into the exciting 8.5" open-hole section of the well with the big fractures and high temperatures.

Drilling will continue for another 1,000m approximately, but this will depend on exactly where we intersect the target fault structure. As soon as we are sure we have drilled through it, we will stop, run further geophysical logs and then conduct a short production test. That will complete the activity on UD-1, so then we will move the rig 8m along the site and start drilling UD-2. The slower than expected drilling speeds means that we are behind our original schedule and we now expect to finish UD-2 at the end of June.

Geothermal Engineering Limited (GEL) secured funding of £10.6 million from the European Regional Development Fund to explore the geothermal resources deep beneath Cornwall.

​With £2.4 million from Cornwall Council and £5 million from private investors, the funding will allow GEL to drill two deep geothermal wells from its site within the United Downs Industrial Estate and build a 1MW - 3MW pilot power plant to demonstrate the technical and commercial viability of supplying both electricity and heat.

(Courtesy George Barber)
The ITB International Geothermal Workshop has been held annually since 2012 by the "Institut of Teknologi  Bandung" (Institute of Technology) which forms part of the Geothermal Master’s Program which has been running since 2008 where approximately 200 graduates have studied and have obtained a master’s degree since the inception of the master's course.

This event was held in Bandung, which is about 180 Kilometer from Jakarta via the toll road which on a good day, (early morning) can take 2 to 3 hours, although normally we can rely on anything from 3 to 10 hours, (still a little time before this will be improved) on March 18 - 22, 2019. This event has become a melting pot for the sharing of knowledge of the advantages and limitations of geothermal energy among other renewable energy in the world, especially Indonesia.  This is the 8th workshop for geothermal in ITB and is looked forward to each year, where a lot of preparation goes into this, it is hoped that this event will run for many more years to come.

Finance: Two Geothermal Energy Turbine Manufacturers Could Form a Joint Venture

Siemens, Mitsubishi Discuss Merger of Turbine Units (Power Mag)

Ready to Spin, by Ross Peden. Poihipi Geothermal Power
Station, Taupo, New Zealand. GRC Photo Contest 2011.
A German business magazine reports that Siemens is exploring options for its struggling gas turbine business, and could look to form a joint venture with Japan’s Mitsubishi Heavy Industries (MHI). Manager Magazin on March 21 said Siemens “wants to accommodate the large turbine business of the Japanese Mitsubishi Group and in the future hold only a minority.”

Turbine manufacturers including Siemens, Mitsubishi, and General Electric (GE) all have struggled in recent years as growth in renewable energy generation takes market share from fossil fuel-powered generation. Overcapacity in the turbine industry has led to strong price competition.

GE was the top producer of gas turbines in 2018, with about 33% of global orders by capacity, according to Barclays Plc. Mitsubishi Hitachi Power Systems, a subsidiary of MHI, was next at 30%, with Siemens at 26%.

Die Stadtwerke München (SWM) haben die dritte von sechs Bohrungen für die Geothermie-Anlage am HKW Süd niedergebracht. Voraussichtlich ab dem heutigen Montag (25. März 2019) sollen Pumpversuche zeigen, ob Ergiebigkeit und Temperatur des Thermalwasservorkommens den Erwartungen entsprechen.

Die Ergebnisse der Leistungstests an den Bohrungen 1 und 2 waren nach SWM-Angaben bereits sehr vielversprechend: Die Temperatur war deutlich höher als erwartet, die Ergiebigkeit lag im Plan. Mit einer Leistung von 50 Megawatt und mehr soll die Geothermie-Anlage regenerative Wärme für mindestens 80.000 Münchnerinnen und Münchner liefern. Bis Ende 2019 sollen die Arbeiten an allen sechs Bohrlöchern abgeschlossen sein. Parallel dazu wird die Heizzentrale gebaut, die auch die Technik beherbergt. Nach finalen Langzeitpumpversuchen soll die Anlage dann im Jahr 2020 ans Netz gehen.

(From Google Translate) Stadtwerke München (SWM) has completed the third of six wells for the geothermal plant at HKW Süd. Probably starting today, Monday (March 25, 2019) pumping tests will show whether the yield and temperature of the geothermal water resources meet expectations.

The results of the performance tests on wells 1 and 2 were already very promising according to SWM data: the temperature was significantly higher than expected, the yield was on schedule. With a capacity of 50 MW and more, the geothermal plant is to supply regenerative heat for at least 80,000 Munich residents. By the end of 2019, work on all six wells is expected to be completed. In parallel, the heating center is being built, which also houses the technology. After final long-term pumping tests, the plant will then go online in 2020.

USA, Hawaii: Puna Geothermal Venture Holds Successful Community Meeting

Puna Geothermal Holds Community Meeting (Big Island Video News)

(Video 26:47 Minutes)

Representatives of Puna Geothermal Venture held a community meeting Friday evening at the Pāhoa High School cafeteria, where they offered to help lava-locked residents regain access to their properties.

Ormat, the parent company of PGV, is planning to move forward with plans to resume operations on the lower East Rift Zone of Kīlauea, where the 2018 eruption of the volcano forced the company to cease operations. Lava partially inundated the facility and blocked access to the plant.

There were concerns that the meeting might be interrupted by residents opposed to the geothermal facility, but those concerns never materialized.

USA: Enhanced Geothermal Systems Could Provide at Least 15% of the Nation's Total Electricity by Midcentury

3 Trends to Watch in Renewable Energy in 2019 (Motley Fool)

Most conversations and policies regarding carbon-free power fail to include two next-generation renewable power sources likely to emerge by 2030: offshore wind power and enhanced geothermal systems (EGS).

EGS is still in the earliest stages of development, but it has equally impressive potential. The technology involves drilling wells deep underground, circulating a fluid over naturally hot rocks, and using the steam created in a closed-loop system to spin turbines on the surface. Unlike conventional geothermal or hydrothermal resources that are dependent on existing geology in a limited number of states, EGS projects could be economical across a wide range of the country.

In fact, the Department of Energy (DOE) thinks the United States has at least 100,000 megawatts of next-generation geothermal potential -- equivalent to the nation's installed nuclear power fleet (although EGS would produce slightly less electricity than nuclear on a power capacity basis, but more than wind or solar). In 2018, the department doled out a record $16 million in grants to accelerate research, and it thinks commercially viable technology could be ready as soon as 2030.

That may sound ambitious, but much of the technology will borrow from hydraulic fracturing ("fracking") techniques developed to tap into American shale oil and gas resources. If the technology works as envisioned, then EGS could provide at least 15% of the nation's total electricity by midcentury. Yet it never shows up in long-term decarbonization projections to 2050.

Kenya: Increase in Profit for GDC Due to Boost in Steam Sales from Geothermal Wells in Olkaria

GDC Posts Profit Of Sh 1.4 Billion (News Release)

The Geothermal Development Company (GDC) posted Sh 2.1 billion profit before tax for the Financial Year 2017/18. This is a sharp increase from Sh 896 million posted the previous year.

The increase in profits is attributed to a boost in steam sales from our geothermal wells in Olkaria. The steam is sold to KenGen for electricity generation.

Speaking at the same function, Dr. Eng. Joseph Njoroge, the PS Ministry of Energy, exuded confidence that with increased income GDC will scale-up its steam exploration operations. 

The PS noted that a huge chunk of Kenya’s geothermal potential is yet to be explored.  Kenya, Eng. Njoroge noted, is only exploiting 600 MW of geothermal out of a potential of 10, 000 MW.

Science & Technology: Measuring the Seasonal Variability Of Geothermal Areas Associated With Hot Dry Rock Systems

Imaging Thermal Anomalies in Hot Dry Rock Geothermal Systems from Near-Surface Geophysical Modelling (MDPI)

By David Gomez-Ortiz, et al

Convective hydrothermal systems have been extensively studied using electrical and electromagnetic methods given the strong correlation between low conductivity anomalies associated with hydrothermal brines and high temperature areas.

However, studies addressing the application of similar geophysical methods to hot dry rock geothermal systems are very limited in the literature.

The Timanfaya volcanic area, located on Lanzarote Island (Canary Islands), comprises one of these hot dry rock systems, where ground temperatures ranging from 250 to 605 °C have been recorded in pyroclastic deposits at shallow (<70 m) depths.

We conclude that the combined use of ground penetrating radar, electromagnetic induction and magnetic methods constitutes a valuable tool to locate and study both the geometry at depth and seasonal variability of geothermal areas associated with hot dry rock systems.
