USA, Nevada: “We commend the extension of the PTC available for geothermal.." - Ormat CEO

Ormat Commends the Extension of Geothermal Tax Credits (News Release)

Continued Support of Geothermal Industry Creates Jobs and Contributes to Nation’s Energy Independence

Ormat Technologies, Inc. today commended passage of the United States federal appropriations bill that retroactively revived and extended the full Production Tax Credit (PTC) for geothermal facilities. The PTC provides a credit for each kilowatt-hour of energy produced by the taxpayer from qualified renewable energy facilities. The PTC for geothermal facilities that expired at the end of 2017 was retroactively revived and extended through 2020, continuing U.S. support for the geothermal industry. This support contributes to the ongoing creation of new jobs in the geothermal industry as well as the nation’s energy independence.

On December 17, 2019, the United States House of Representatives passed the tax extenders package, allowing geothermal projects that begin construction before the end of 2020 to claim PTCs when the project is later placed in service, or to elect to receive in lieu of such PTCs, an Investment Tax Credit (ITC). On December 19, 2019, the United States Senate passed this bill and it was signed into law by President Donald Trump on December 20, 2019.

“Geothermal energy remains a key element of our country’s energy portfolio, enabling higher renewable penetration and greenhouse gas reductions,” said Isaac Angel, Ormat’s Chief Executive Officer. “We commend the extension of the PTC available for geothermal, which helps level the playing field with other technologies and provides predictable market signals for project development. This, in turn, helps leverage private investment to create new Jobs and drive economic benefits across the country.”

USA, California: "...mineral extraction from geothermal brine will change the economic future of this valley,”

Salton Sea land owners may luck out (San Diego Reader)

Lithium in the geothermal brine – if they can only extract it

Even though there are hurdles, both Ryan Kelley, the Imperial County District 4 supervisor and William Pettitt, the executive director of the Geothermal Resources Council, seem quite optimistic about the future potential for geothermal energy in this region.

“The Imperial Valley and Salton Sea, that area is a huge geothermal resource,” Pettitt said. “It has huge potential in the future for supplying power and should be a large component of California’s electricity demand in the future. There’s a big potential there. That obviously leads to huge benefits for the local economy. Geothermal is a really good power source in terms of providing good, stable jobs for folks that work in it. And, obviously, it has a large amount of support from companies around it that would all feed into the economy.”

Kelley, who oversees the daily economy of the region, echoed Pettitt’s views on job creation. He also lamented the fact that Tesla decided to open their Gigafactory for lithium-ion battery and vehicle sub-assembly in Sparks, Nevada (near Reno) as opposed to in his district. There is lithium in the geothermal brine that reaches the surface during the mining process, but the technology to extract it from that brine (while still turning a profit) has yet to be developed. Kelley added that the area near Reno that Tesla chose has “open ground, hard-rock” traditional lithium mining, and that’s likely why they were selected.

But if the puzzle that is extracting lithium from geothermal brine in a cost-effective fashion can be solved, the Imperial Valley may transform into a mining super-power.

“There are companies now exploring that and trying to bring that lithium recovery into part of their business model,” Pettitt explained. “On some estimates, the Salton Sea region alone could provide, I believe, two-thirds of the lithium demand in 2025 (worldwide) if the engineering for recovering that lithium was successfully implemented. That brings in a lot of real interest because if you are recovering the lithium in that area you can also bring in battery manufacturers into the equation as well as electric vehicle manufacturers. You could really change the economy down there in a big way if that lithium resource started to be developed forever.”

Kelley has the same hope. “We still believe that the mineral extraction from geothermal brine will change the economic future of this valley,” he said.

Uganda: Exploration Drilling for Geothermal Energy to Start Next Month

Govt starts process to generate 1,500 MW geothermal energy (S24)

The [Ugandan] government has awarded a contract worth Shs2.3 billion to Royal Techno Industries Ltd to embark on developing and exploiting the thermal energy plants in Hoima and Nebbi districts. Under the exploration programme, the company will drill 16 temperature gradient holes in Kibiro, Hoima District and in Panyimur, Nebbi District.

According to Vincent Kato, the coordinator of thermal energy in the Energy ministry, drilling will start in January 2020. “The exercise will take about two months. Holes with the highest temperature gradient will help site deep exploration wells,” he said. Kato revealed that the project is jointly funded by the Geothermal Risk Mitigation Facility of the African Union Commission. He added that in the next two years, geothermal energy will be ready for use. “We are planning to use well-head technology to generate megawatts as we prepare to construct power plants,” Kato said.

Koti Reddy, the managing director of Royal Techno Industries, said that they will apply the down-the-hole drill and mud rotary drilling methods. He appealed to government to sensitise residents about the benefits of the project to avoid hostility. Kato said that the steam from the Geothermal plants will also be used to heat the crude oil pipeline, fish drying and other uses.

New Zealand: Geo40 and Climeon to Establish Combined Mineral extraction and Geothermal Power Production Plant Next Year

Climeon enters strategic partnership with Geo40 (News Release)

Geo40's commercial demonstration plant at Ohaaki.
Climeon has entered into a collaboration agreement with the New Zealand-based geothermal minerals firm Geo40 to strengthen the companies’ geothermal offering and enable an expansion into waste heat recovery at existing geothermal power plants, so-called bottoming cycles. The companies will be working together to establish a first combined mineral extraction and power production plant during 2020.

Geo40 has developed a technology to extract silica and other minerals from geothermal brine, the hot wastewater that remains after high temperature geothermal power production. The silica in the brine causes scaling in geothermal pipes and wells and limits the heat that can be extracted and utilized for power generation. By extracting and removing the silica and other valuable minerals like lithium, Geo40’s technology reduces operating costs for geothermal power stations, while producing sustainably sourced minerals. The filtered water from Geo40’s application can then be utilized in Climeon’s Heat Power modules to produce clean electricity and increase power output at geothermal power stations. Bringing together the two firms’ technologies opens up a wide range of global opportunities, particularly in recovering waste heat from existing geothermal power plants, so called bottoming cycles.

Australia: Association Makes the Case for Geothermal Down Under

Geothermal Energy Can Provide a Source of Low Emission Electricity Generation in Australia (Australian Geothermal Association)

A recent Australia-wide census by the Australian Geothermal Association (AGA) showed that geothermal energy is already making a useful contribution to the Australian energy mix; direct-use geothermal is a successful and growing industry. Geothermally generated electricity can also play a role in Australia’s energy transition, but to achieve progress it is critical that government policy acknowledges and supports this potential.

The Australian geothermal industry experienced a sustained surge in activity from 2000-2013 focussed on developing innovative technologies with huge potential. Although these efforts were not commercially successful, more conventional approaches to generating electricity with geothermal energy remain viable. For example, a new geothermal power plant was recently commissioned in Winton, Queensland. The 310 kW plant is currently the only operating project in Australia, although a similar geothermal power plant in Birdsville, Queensland provided over 20 years of reliable service until it was decommissioned recently. These two successful projects demonstrate that lingering perceptions that geothermally generated electricity is not possible in Australia are inaccurate.

Science & Technology: Phosphonate Chemistry is Useful in Ultrahigh Geothermal Applications

Novel Phosphonate Proves Useful in Geothermal Environments (Materials Performance)

It is imperative that chemicals used in geothermal applications be environmentally friendly. Governmental pressure is increasingly pushing toward greener chemistries, which creates a challenge to find products that can withstand the extreme environments found in geothermal systems and also be biodegradable.

The biodegradability of the novel phosphonate was evaluated to gauge its suitability for use in Norway. A closed-bottle method was used, involving a predetermined amount of chemical being dissolved into seawater. The solution remained in dark conditions and a constant temperature was maintained. Dissolved oxygen analysis was carried out at specific desired time periods. The results showed that the product is considered biodegradable because testing showed greater than 20% biodegradation after 28 days of testing.

The researchers conclude that the novel phosphonate chemistry is useful in ultrahigh geothermal applications. Its high tolerance to calcium, biodegradability, thermal stability, and good performance against calcium carbonate scaling prove valuable in a variety of environments.

Japan: Geothermal Power Plant Manufacturers Part Ways

Hitachi Exiting MHPS; MHI Will be Venture’s Sole Owner (Power Mag)

MHPS is a long-term exhibitor at the GRC Annual Meeting & Expo

Japanese technology conglomerate Hitachi will withdraw from Mitsubishi Hitachi Power Systems (MHPS), a joint venture it established in 2014 with another power equipment giant, Mitsubishi Heavy Industries (MHI), over a dispute stemming from construction of two massive defect-ridden coal plants in South Africa.

Under a Dec. 18-announced settlement reached by MHI and Hitachi, Hitachi will pay MHI 200 billion yen ($1.8 billion) in March, and transfer its 35% stake in MHPS to MHI, which currently holds the remaining 65%.

The two Japanese giants created the flagship power plant and equipment venture company to combine their thermal power generation businesses in February 2014, with an eye toward gaining more clout in a rapidly changing global power market. MHPS has since grown into a massive company with nearly 19,000 employees, and today is a brand-name builder of gas, steam, integrated coal gasification combined cycle (IGCC), and geothermal plants, and a solid contender in the gas turbine, steam turbine, boiler, environmental controls, generators, control systems, and fuel cell markets.

Indonesia: Sumitomo and Engie to Build 220 MW Geothermal Power Plant in Sumatra Starting 2023

Indonesia lures Sumitomo to its geothermal power sources (Nikkei)

Trading house joins with French energy company Engie in renewables projects

Japanese company Sumitomo Corp. has joined geothermal power projects in Indonesia designed to eventually generate 400 megawatts worth of electricity, a small step toward the trading house's long-range goal of deriving 30% of its total power output capacity from renewable sources.

If the projects go well, Sumitomo intends to use them as stepping stones into the geothermal power generation business in the Philippines and the U.S.

As the first of two joint projects in the nation, Sumitomo and its partners this month have begun operating the Muara Laboh geothermal power plant in the central part of Sumatra. The facility was built at a cost of 70 billion yen ($640 million). The 85 MW plant is capable of supplying electricity to 420,000 households. It is Sumitomo's first concession in geothermal power generation.

Sumitomo and Engie of France each own 35% of the plant, with Supreme Energy of Indonesia holding a 30% stake. Power will be supplied to PLN, the Indonesian state-owned electricity utility, at a fixed price for 30 years.

In 2023, Sumitomo will join Engie and other partners in building a geothermal plant capable of generating up to 220 MW in Rajabasa, at the southern tip of Sumatra. Plans are for the plant to begin operating in 2025.

Science & Technology: Magnitude and Orientation of the Background Hydraulic Gradient, are Prime Parameters that Affect Lifetime of a Geothermal Reservoir

A numerical sensitivity study of how permeability, porosity, geological structure, and hydraulic gradient control the lifetime of a geothermal reservoir (Solid Earth)

By Johanna F. Bauer, et al
We show, using over 1000 (n=1027) 4-D finite-element models of a simple geothermal doublet, that the lifetime of a reservoir is a complex function of its geological parameters, their heterogeneity, and the background hydraulic gradient (BHG). In our models, we test the effects of porosity, permeability, and BHG in an isotropic medium. Furthermore, we simulate the effect of permeability contrast and anisotropy induced by layering, fractures, and a fault. We quantify the lifetime of the reservoir by measuring the time to thermal breakthrough, i.e. how many years pass before the temperature of the produced fluid falls below the 100 ∘C threshold.

The results of our sensitivity study attest to the positive effect of high porosity; however, high permeability and BHG can combine to outperform the former. Particular configurations of all the parameters can cause either early thermal breakthrough or extreme longevity of the reservoir. For example, the presence of high-permeability fractures, e.g. in a fault damage zone, can provide initially high yields, but it channels fluid flow and therefore dramatically restricts the exploitable reservoir volume.

We demonstrate that the magnitude and orientation of the background hydraulic gradient (BHG), provided permeability is sufficiently high, are the prime parameters that affect the lifetime of a reservoir. Our numerical experiments show also that BHGs (low and high) can be outperformed by comparatively small variations in permeability contrast (103) and fracture-induced permeability anisotropy (101) that thus strongly affect the performance of geothermal reservoirs.

USA, California: Internship Opportunities at The Geysers Geothermal Field

Vacancy: Performance Engineering Intern - Calpine at The Geysers

Location: The Geysers power plant near Middletown, California

The Geysers is the largest complex of geothermal power plants in the world. Calpine is the largest geothermal power producer in the US and one of the most reliable energy sources in California accounting for approximately one fifth of the green power produced in California. See for more information regarding Calpine.

Essential Duties and Responsibilities will include some or all of the following:

Assisting the Geysers Power Plant Process Engineering & Performance Management team with ongoing monitoring, evaluating, and optimizing 1) corrosion mitigation and steam scrubbing systems to achieve required steam purity, 2) plant performance (efficiency and total output), and 3) other projects that improve reliability.

This will be done by gaining hands-on experience in engineering projects, e.g.
  1. Measurement of steam enthalpy with a calorimeter for steam scrubbing / moisture removal efficiency testing and optimization of desuperheat systems. Development of automated reports for pipeline mass balances to track transport and removal of steam impurities for monitoring effectiveness of corrosion mitigation at varying steam flows.
  2. Power plant performance testing, evaluation of test data, and identification and recommendation of opportunities for cycle optimization and equipment upgrades.
  3. Analysis of steam gathering pipeline system and pressure protection in accordance with ASME B31.1 Power Piping Code, and silencer sizing and selection.
  4. Model and recommend opportunities for improvement of condensate gathering and reinjection pipeline system, including replacement pump specification.
The above statements reflect the general details considered necessary to describe the essential functions of the job and are not to be construed as a detailed description of all the work requirements that may be inherent in the position.

New Zealand: Heat Exchanger Delivered to Ngāwhā Geothermal Power Station

The biggest thing on wheels: 'Supertruck' brings 90-tonne heat exchanger to Ngāwhā power station (NZ Herald)

The biggest thing ever transported on Northland roads, which will form a key part of Top Energy's new geothermal power station at Ngāwhā, made a show (and traffic) stopping sight as it rumbled up SH1 last week.

The 90-tonne, 20.5m heat exchanger made was transported on an 18-axle, 144-wheel trailer pulled by two trucks and pushed by a third.

Top Energy chief executive Russell Shaw said the Israeli-built heat exchanger, or pre-heater, would be used to extract energy from geothermal fluid drawn from deep underground. Heat from the fluid would turn pentane into a high-pressure gas, which would spin a series of turbines, which would turn a generator, making electricity.

The new power station is due to start producing electricity in August next year.
