The high cost and long time of conventional large-scale geothermal development has been a challenge for the geothermal sector ever since it started. So there have been various approaches to help provide a faster development.
A Mexican company has now developed a small-scale 500 kW plant that could be installed on exploratory wells. The company Grupo Enal has developed this portable unit.
“We came to this solution while working for a producer that needed to start generating energy to support the development of their geothermal projects. Our client was considering either diesel generators or solar roofing. However, we decided to take advantage of the existing geothermal resource placed there. After some engineering, we created the first geothermal plant for distributed generation with a production capacity of 20kW,” explains Gerardo Hiriart, Director General of Grupo Enal. After further engineering and hard work, Enal has now developed a 500 kW geothermal portable power plant that is ready to be tested in real life conditions.
The overall concept of a small-scale geothermal plant is though actually not new. There have been small-scale and portable units with ORC technology all from a few kW to 100-200 kWh, as well as smaller-scale flash-condensing units. With an average size of wells of around 2-3 MW, it would be interesting to see if these small units could actually utilise slim holes.
The solution now offered by Grupo Enal seems to be a backpressure-unit.
Essentially it comes down to financial modelling to see if this makes financial sense. With regards to testing the reservoir this could be indeed interesting, but if it provides sufficient

How’s the ventilation in your kitchen? Consider yourself lucky if your kitchen range is ventilated to the outdoors. That’s the best way to get rid of irritating smoke and water vapor, which can add humidity in your home, making you feel uncomfortable and even causing issues with mold and mildew. If you don’t have adequate kitchen ventilation, maybe it’s time to look into it.
Types of Kitchen Ventilation
The most favored type of kitchen ventilation is of the updraft design. These use a blower to inhale cooking vapors, then push them through a duct which, we hope, exhausts the vapors through the roof rather than the attic. These are likely to be in the form of hoods or canopies, purchased separately from the stove.
The downdraft type draws cooking vapors across the surface of the range, and down through a duct that exhausts to the outdoors. These are likely to be integrated into the cooking appliance’s surface. The main drawback in using them is that they do not rise more than 10 inches above the surface of the range, and so cannot capture steam from a tall pot. They are usually chosen when they are to be incorporated into an island where the homeowner doesn’t want a view blocked, or in a kitchen with a high ceiling, where ductwork would be too high to work effectively in the updraft model.
Whichever type you choose, be sure that it can move the volume of air you will need to move in relation to the heat output of your range. Your ventilation specialist can help you calculate this.
Installing Kitchen Ventilators
If you have an older house, you may already have ducts in place that can accommodate the installation of new, upgraded kitchen ventilation. If the ductwork isn’t in the right position to accommodate a new range hood or canopy, you will have to move it. Unless you’re an accomplished DIYer, you may need a ventilation and ductwork specialist to advise you on installation.

In a release by the developer and supplier, Empower Energies, Inc., it was announced that the company has completed the construction of the Patua solar power project, a 14.5MW DC solar array in Churchill County, Nevada (original release says Utah). The project supplements the existing 25 MW Patua geothermal power plant by CYRQ Energy.
Empower advised CYRQ on the development and design of the Patua solar project, including the selection of the solar equipment, which included approximately 45,360 photovoltaic (PV) solar panels, and the EPC for the construction and commissioning of the project. As construction manager, Empower’s development and operations team assisted CYRQ with optimizing the design of the project, overseeing supply chain management issues, and managing the project construction schedule with the EPC. The project was completed at the end of July, ahead of schedule and under budget.
“We were very impressed with the expertise and support we received from Empower Energies in working with our team on the design and completion of this critical project,” said Nick Goodman, CEO of CYRQ Energy. “We look forward to continuing to work with Empower on other solar projects to support our geothermal activities in the U.S.”
“The Patua project is a prime example of the strength of Empower’s flexible business model in the clean energy industry,” said John Clapp, President and CFO of Empower Energies. “We are able to deploy our development and operations teams to deliver high quality solar and related clean energy projects throughout the U.S. for customers whether they intend to own the project themselves, like CYRQ Energy, or seek third party financing through our DG Fund.”

Reporting on its half year results, geothermal power producer Energy Development Corp. announces consolidated recurring net income attributable to equity holders of the parent company increased 11 percent in the first half to P5.2 billion ($111 million) from P4.7 billion ($91 million) it booked in the same period last year.
EDC said in a disclosure to the stock exchange consolidated revenues rose 4 percent in January to June to P17.7 billion ($346 million) from P17 billion ($332 million) a year ago.
The company attributed the increase in revenues to higher energy sales of Unified Leyte plants and the reduction in the Bacman plant’s exposure to the electricity market.
“First-half 2017 results confirm progress EDC has made in boosting cash generation and in delivering financial predictability to investors by addressing the uncontracted portion of its Bacman power plants and by undertaking an extensive asset reliability program for the Leyte Power Plants,” EDC chief financial officer Nestor Vasay said.
Inclusive of non-recurring items, consolidated net income attributable to equity holders of the parent declined 6 percent to P4.6 billion from P4.9 billion in the same period last year.
EDC said the decline was driven by higher operating expense, forex losses on loans and loss from the early redemption of a portion of the company’s US dollar denominated bonds, partly offset by higher revenues mainly from Unified Leyte and the Bacman power plants.
“Earnings growth was strong during the first half of the year, but will likely become moderate for the second half of 2017 following the magnitude 6.5 earthquake that struck the island of Leyte last July 6,” Vasay said.
He said EDC remained steadfast and exerted efforts to expedite the return to service of the generating capacity of the Leyte plants back to its pre-earthquake levels.
The company’s financial position remained strong with cash balance of P10.9 billion ($212 million).
EDC, an affiliate of First Gen Corp. is a part of the Lopez Group of Companies. It is the largest producer of geothermal energy and one of the leading renewable energy companies in the country.

In an article published earlier this month, the Journal of Petroleum Technology talks about technologies designed to produce heavy oil with hot steams.
The article discusses findings of an applied research group in Alberta, Canada on how technologies involved with heavy oil have the potential to be used around the world.
The author describes how the technologies could be used to produce geothermal power instead of oil.
With a reference to enhanced/ engineered geothermal systems (EGS), it is described how steam-assisted gravity drainage (SAGD). Canadian company C-FER Technologies describes how the geothermal sector could be using new SAGD technologies “to make capturing rock heat more efficient and improve the output of this type of power plant. To prove whether the idea is feasible, C-FER is seeking partners for a new joint industry project that it recently proposed.
The ultimate aim is to design a dual-well geothermal plant capable of generating between 1 MW and 5 MW. That is comparable to a wind turbine that may generate between 2 MW and 3 MW. There is one big advantage with the geothermal route vs. other renewables: the former can generate baseload power when the sun is not shining and when the wind is not blowing.”, so Brian Wagg, Director of Business Development at the Edmonton-Canada based C-FER Technologies.
The motivation for this research is clear, to help Canadian oilfield equipment manufacturers and service companies expand beyond the struggling heavy-oil sector.

Top Energy, a local electricity generation and lines network company servicing 30,000 electricity consumers on the North Island of New Zealand, has been operating the Ngawha geothermal power plant since 1998. With an installed capacity of currently 25 MW it plays an important role in the supply of electricity, with around 70% of all electricity consumed in the far North of the North Island.
The company is planning a further expansion at the existing plant, by building two new 25 MW plants. The first plant could be commissioned in 2023.
Reporting on its financial results for the past year, the company reports a revenue increse of NZ$800,000 for the year, despite a planned extensive annual maintenance outage and an annual plant availability of 96.6%.
With the ongoing expansion work, revenues from its geothermal business could increase even further.

Thai Luxe Enterprises plans investment into a geothermal power project in Japan. As reported by Reuters, the board of the company has approved the planned investment.
Initial news reported a possible investment of Thai Baht 755.72 million (or around $23 million), in 8 geothermal plants. The company expects to derive revenue from the new investment in the third quarter of this year. An additional three geothermal plants are being considered. The company expects annual revenues of Thai Baht 130 million ($3.9 million) from the 11 geothermal plants. But the company has further plans with up to 56 plants by 2018.
The company reported in December last year that its CEO visited a geothermal power plant at Beppu in Oita Prefecture, Japan.
Thai Luxe Enterprises is a company with a focus on animal feeds, but has established a subsidiary focused on its geothermal investment, called TLuxe Power.
The company plans to build a total of 12 small-scale geothermal power plants with an installed capacity of 125 kW, all located in Oita Beppu, Japan.
Currently four units are installed with a total capacity of 500 kW (4x 125 kWh).
State-owned oil giant China Petroleum & Chemical Corp, also known as Sinopec Corp., the third largest oil company in the world, is pushing forward with its plans for geothermal development, as we previously reported.
The company has concrete plans to create 20 “smokeless cities” by replacing coal-fired heating with clean energy, as reported by China Daily. It plans to further develop geothermal projects in Xiongxian county, Hebei province, as it seeks to make the region smokeless. Sinopec Corp is also diversifying beyond oil and gas production.
The company said its geothermal energy heating capacity in Xiongxian has reached 4.5 million square meters by July 2017.
It now plans to create 20 smokeless cities nationwide replacing coal with geothermal energy, covering 100 million sq m during the 13th Five-Year Plan (2016-20).
“Geothermal energy has the capacity to partially replace coal-fired heat and reduce carbon footprint, especially in big cities,” said Wang Zizong, deputy chief engineer of Sinopec Corp, Asia’s largest refiner.
Xiongxian county is part of the Xiongan New Area, a zone located some 100 kilometers southwest of downtown Beijing.
The area was set up for coordinated development of the Beijing-Tianjin-Hebei region, which also spans Rongcheng and Anxin counties in Hebei province.
According to Sinopec, up to 60 percent of the Xiongxian county is rich in geothermal energy resources, with its reserves of hydro-geologic water amounting to 82.1 billion cubic meters.
The local groundwater temperature exceeds 55 degrees Celsius, equivalent to 6.63 billion metric tons of standard coal.
Sinopec has cooperated with Iceland in geothermal energy development long ago. It signed a framework agreement on the expansion of geothermal development and cooperation with Orka Energy Holding Ehf in 2012 and formed a joint venture with the company in 2006.
The JV, Sinopec Green Energy, moved its headquarters to Xiongan in April, seeking to provide over 16 million sq m of heating area generated by clean energy.
According to Li Yangzhe, deputy director of the National Energy Administration, is taking energy transformation place at a rapid pace globally, and renewable energy will play an increasingly significant role in shaping the global energy system.
“The Chinese government is devoted to promoting energy transformation in the country, and has set a goal to raise the percentage of nonfossil energy consumption in primary energy consumption to 15 percent by 2020, which will rise to 20 percent by 2030,” Li said.
China is rich in geothermal energy resources, with the Tibet autonomous region, and Yunnan and Sichuan provinces considered the best among them. The country plans to boost geothermal energy generation in these areas.
In 2016, to promote clean energy development and improve the environment, China launched the 13th Five-Year Plan for geothermal energy, the first such plan in this field.
During the 2016-2020 period, China plans to increase installed capacity in the geothermal segment by 500 gigawatts, attracting 40 billion yuan ($5.8 billion) in investment. Meanwhile, China will also enlarge the geothermal heating area by 1.1 billion sq m.
By 2020, China will have 530 million watts of installed capacity in geothermal power as well as 1.6 billion sq m geothermal heating area, according to the country’s energy planner.
Zhang Jiehui, deputy governor of Hebei province, said the geothermal resource in Hebei province equals 5 billion tons of standard coal, ranking second in the country.
It is estimated that the total energy consumption of Hebei province this year will reach 350 million tons.

New wells work-overs and deep drilling project to help regain full capacity of Reykjanes geothermal plant
In its recent release on quarterly results, Canadian Alterra Power Corp. provides details on the geothermal operations of HS Orka in Iceland.
In recent months, HS Orka has made some significant improvements to its geothermal field at Reykjanes. With well venting, turbine pressure adjustments and more, the company increased generation capacity to 75 MW, the highest output level in 14 months. The Reykjanes geothermal power plant has an installed capacity of 100 MW and is performing below that capacity.
Quarterly generation increased 5% compared to the fourth quarter of 2016 and 3% over the previous quarter. The Company expects further increases in plant output in 2018 from the drilling of planned new wells, well work-overs, and potentially from the recent deep drilling project.
The company also announced the Termination of Blue Lagoon sales process, as we reported earlier. The sales process was for the 30% stake in the Blue Lagoon held by HS Orka. Although multiple offers were received in excess of EUR 90 million, Alterra’s partner, Jarðvarmi slhf, whose consent was required, decided against selling the stake at this time.
The company also announced having settled a $71 million bond for its Icelandic holdings. On July 27, the Company’s subsidiary Magma Energy Sweden signed an agreement to fully settle and extinguish the $71.3 million liability associated with the Reykjanesbær bond. Under the terms of the settlement agreement, the Company obtained a release of the $71.3 million liability under the bond and delivered the collateral (a 12.7% ownership stake in HS Orka).

The Provincial Government in Biliran, Philippines – an island in the Eastern Visayas – is confident it will be able to attract more investments, with the completion of geothermal and solar power projects. The island of Biliran lies to the north of Leyte, the location of a large number of geothermal power plants.
Biliran Governor Gerardo Espina Jr. said although Biliran was small, they were “lucky that some investors are interested to put investment here.” “The geothermal and solar power plants show that we have something to offer to investors,” Espina said.
“This will mean economic development, possible reduction of electricity rate, and power stability. But the investment’s main benefit for us is on job generation especially in towns where power plants are located,” Espina said earlier this year. The power plant by Biliran Geothermal Incorporated (BGI) is located in Caibiran town, while the Biliran Solar Power Plant of E and P Green Energy Inc (EPGen) is located in Biliran town.
The plants will mean economic development, possible reduction of electricity rates, and power stability. The geothermal power plant seeks to generate 10 MW, while the solar power plant is targeting to generate 25 MW with plans to start the plant early next year.
With a status of May this year, BGI expects the geothermal power plant to be operational by September 2018 and was in the process of negotiating power purchase agreements with electric power distribution utilities
An international group of geoscience experts will convene in Bend Sept. 10-14 to develop a proposal for drilling one of the hottest wells in the world at Newberry Volcano in central Oregon.
More than 40 scientists and engineers will meet at the Oregon State University-Cascades campus in Bend to explore options for the geothermal energy project, as well as funding potential. The workshop is sponsored by the International Continental Drilling Program, a non-profit organization that supports international science teams pursuing land-based drilling.
The event is being coordinated by the NEWGEN consortium, which was formed in 2015 by Pacific Northwest National Laboratory, AltaRock Energy, Oregon State University and Statoil to develop a research observatory on geothermal energy on Newberry Volcano.
The Newberry Geothermal Test Facility, located on the western flank of the caldera rim of Newberry Volcano, is one of the largest geothermal heat reservoirs in the western United States. Hot rock is relatively close to the surface at the site, making it easier to drill super-hot wells and carry out enhanced geothermal system research, according to Adam Schultz, an OSU geologist and geophysicist involved with the effort.
‘There is enormous geothermal energy potential in the United States, with the greatest concentration of resources in the West,’ Schultz said. ‘Our test site at Newberry Volcano represents one of the most promising geologic settings for geothermal power in the West, where super-hot rock could produce a high yield of stable, baseline electric power production that – unlike other renewable energy sources – doesn’t vary with sunlight, wind or wave conditions.
‘Geothermal can serve as a like-for-like replacement for coal, oil, gas and nuclear power that can operate 24/7 and underpin our nation’s energy supply. By drilling deep beneath the west flank of the volcano, we can develop new technologies for green, carbon-free energy production.’
The site has been studied for 40 years and millions of dollars have been invested there by the U.S. Department of Energy and private geothermal developers, resulting in a ready-to-use facility with the necessary infrastructure, environmental permits, land commitments, and monitoring plans.
An idle geothermal exploration well drilled in 2008, which is 3,500 meters deep, has temperatures of 320 degrees Celsius (608 degrees Fahrenheit) at the bottom. Researchers are evaluating plans to deepen the well another 1,500 meters to reach temperatures above 450 degrees Celsius (842 degrees Fahrenheit).
Scientists and engineers with expertise in geothermal energy, high-temperature drilling, seismology and volcanology are expected to attend the workshop. They are from the U.S., Canada, Japan, Norway, Iceland, France and Italy.
