Italy: Heat from Chiusdino Geothermal Power Plant Helps Grow "Superfood"

Geothermal Energy and Spirulina: from Tuscany to Space (News Release)

In Chiusdino, Italy, Enel Green Power is collaborating in tests to cultivate the algae spirulina in geothermal environments: a key step to creating the “superfood” that could even be used by future astronauts.

Launched last year, the project involved the construction of the world’s first greenhouse for the cultivation of spirulina heated by the earth, with smart and sustainable reuse of the C02 waste produced by geothermal plants. At the 125-mq plant, spirulina is grown in open tanks and photobioreactors at a rate of 60 grams a day.

Heat for the greenhouse is provided by our Chiusdino geothermal power plant. The plant, in operation since 2011 with an installed capacity of 20 MW, produces about 150 million kWh a year, avoiding the emission of 100,000 tonnes of CO2 into the atmosphere, and saving fossil fuels equal to 32,000 TOE (tonne of oil equivalent) annually.

Europe: “Our Vision is that by 2050 geothermal energy can cover a significant part of domestic heat and electricity demand”

Vision for Deep Geothermal: Looking towards 2050 (EGEC)

In the birthplace of geothermal energy (Pisa, Italy), the European Technology & Innovation Platform on Deep Geothermal (ETIP-DG) has presented its “Vision for Deep Geothermal”to look at future development of deep geothermal energy and highlight the great potential of untapped geothermal resources across Europe.

Meeting this week in Tuscany, a region where geothermal already employs nearly 10,000 people and provides clean and reliable energy to thousands more, helping reduce dependency from fossil fuels imports, the ETIP-DG releases its Vision document and launches works on its Strategic Research Agenda.

“Our Vision is that by 2050 geothermal energy can cover a significant part of domestic heat and electricity demand,” said Ruggero Bertani, Chairman of the ETIP-DG. “As a local and stable source of renewable energy, geothermal will be crucial in the future energy system, providing power, heat and thermal storage.”

USA, Washington: Exploratory Drilling for Possible Geothermal Resources to Begin This Summer

Are Washington's volcanoes the next big energy source? (KUOW)

Washington's volcanoes could one day join solar and wind as producers of renewable energy. The state Department of Natural Resources (DNR) plans to tap into the idea this summer.

(Audio 1:29 Minutes)

Geologists think there could be pockets of geothermal resources throughout Washington state, but there's no clear data showing where. The state’s Department of Natural Resources wants to check for hot spots under the state's major volcanoes.

DNR spokesperson Joe Smillie said this will be the first time the state has searched far below the volcanoes. They're getting ready to take action after the legislature passed a bill last year allowing deeper drilling for geothermal resources.

"We'll be drilling some test wells this summer by Baker Lake, which is near Mount Baker, and about 15 miles northwest of Mount St. Helens," Smilie said.

If their search is successful, utilities could eventually apply to build geothermal power plants in the area.

New Zealand: Geothermal Powered Industrial Park Gets Go-Ahead

Council gives $5m green light to Ngawha industrial park (NZ Herald)

Far North ratepayers will invest $5 million in an industrial park near Kaikohe in what is being described as a ''once in a lifetime opportunity'' to boost employment in the Mid North.

Councillors voted unanimously yesterday to borrow $5m which council-owned company Far North Holdings (FNH) will use to buy a dairy farm at Ngawha and turn it into a ''market ready'' industrial park.

The idea is to lure industry with completed infrastructure and resource consents, but the real drawcard will be cheap power from the nearby Ngawha geothermal power station.

FNH chief executive Andy Nock told councillors that Top Energy could supply power to the park, on a dairy farm on the northern side of State Highway 12, at a discount of 30-40 per cent and with no line charges. There was also potential to supply heat and CO2, for example for hydroponic horticulture.

Germany: Taufkirchen Geothermal Power Plant Begins Electricity Generation

Daldrup & Söhne AG: Successful test operation and stable power production in Taufkirchen geothermal power plant (News Release)

The geothermal power plant of GeoEnergie Taufkirchen GmbH & Co. KG, a subsidiary of the drilling technology and geothermal specialist Daldrup & Söhne AG, has started electricity production in Taufkirchen.

The first feed-in was preceded by successfully completed system tests of the components of the power generation plant in recent days. This means that, for the first time and in parallel to the district heating supplied to the communities of Taufkirchen and Oberhaching, environmentally friendly electricity generated at the power plant will now be fed into the public grid.

With the weather-related decline in district heating production, the power production of the plant is being ramped up further. A further heat exchanger will be connected in the second half of 2018. Thus, from today's perspective electricity production will then gradually switch to full load operation. For the further planning of the 2018 financial year, the management board assumes that corresponding feed-in revenues can be generated from power generation.

Canada: Abandoned New Brunswick Mine to Provide Geothermal Heating and Cooling for Community

Geothermal heating a good use of flooded Picadilly mine, report says (CBC)

The core idea behind geothermal heating involves extracting the heat of the water deep inside the mine.

More than two years after Sussex was rocked by the closure of the Picadilly mine, the town is getting some good news about the mine —  it can likely be used for geothermal heating.

The mine in Penobsquis, near Sussex, was allowed to flood after operations ended there in 2016, and 430 jobs were lost.

Geothermal heating involves extracting the heat of the water from inside the mine. A company could then use that energy cheaply, making Sussex more attractive for new industry.

Scott Hatcher, chief administrative officer for the town said it appears from the feasibility study that the model that would most benefit the town is something called an "open loop" geothermal system, which would involve directly extracting the hot water, drawn through a pipe. "Once used, it would be injected back into the mine," Hatcher said.

USA, Wyoming: New Research Strongly Supports a Deep Origin for the Yellowstone Hotspot

Lower-mantle plume beneath the Yellowstone hotspot revealed by core waves (Nature Geoscience)

The Yellowstone hotspot, located in North America, is an intraplate source of magmatism the cause of which is hotly debated. Some argue that a deep mantle plume sourced at the base of the mantle supplies the heat beneath Yellowstone, whereas others claim shallower subduction or lithospheric-related processes can explain the anomalous magmatism.

Here we present a shear wave tomography model for the deep mantle beneath the western United States that was made using the travel times of core waves recorded by the dense USArray seismic network.

The model reveals a single narrow, cylindrically shaped slow anomaly, approximately 350 km in diameter that we interpret as a whole-mantle plume. The anomaly is tilted to the north-east and extends from the core–mantle boundary to the surficial position of the Yellowstone hotspot. The structure gradually decreases in strength from the deepest mantle towards the surface and if it is purely a thermal anomaly this implies an initial excess temperature of 650 to 850 °C.

Our results strongly support a deep origin for the Yellowstone hotspot, and also provide evidence for the existence of thin thermal mantle plumes that are currently beyond the resolution of global tomography models.

USA: Congress Requests Increased Spending for Department of Energy

Congress' spending deal rejects Trump's proposed EPA, energy cuts (Washington Examiner)

Congress on Wednesday night released a fiscal 2018 spending bill that rejects Trump administration efforts to reduce funding for the Environmental Protection Agency and Energy Department.

After President Trump threatened to make massive cuts to the EPA budget, Congress decided to keep funding levels the same from fiscal 2017, at $8.1 billion.

The Energy Department, meanwhile, would receive $34.5 billion in the massive spending deal, a $3.77 billion increase over fiscal 2017.

That includes $2.32 billion for the agency’s energy efficiency and renewable energy division, a 15 percent increase. Trump, who has promoted expanded fossil fuel development, had sought to cut funding for that division.

China: Sinopec Green Energy Geothermal Co to Develop District Heat Projects in Capital Region

ADB signs $250 million loan deal for China geothermal heating (Morung Express)

Asia Development Bank (ADB) said on Thursday it would provide a $250 million loan to Sinopec Green Energy Geothermal Co (SGE) and Iceland’s Arctic Green Energy Corp (AGE) to develop clean geothermal heat in smog-prone northern China. SGE is a joint venture set up by China’s state-owned oil giant Sinopec and AGE.

The project will focus on the Beijing-Tianjin-Hebei region, but SGE chairman Liu Shiliang said the partners plan to “replicate their successful collaboration across Asia.” China had planned to develop geothermal energy in the Beijing-Tianjin-Hebei belt as part of its anti-smog campaign, the country said in guidelines published in January.

Turkey: 165 MW Kizildere III Geothermal Power Plant Completed

Zorlu completes Turkey’s largest geothermal plant (NewsBase)

Somewhere Over The Rainbow: Kizildere Power Plant. By Erdinҫ Sentϋrk. GRC Photo Contest.
Zorlu Dogal Elektrik, a subsidiary of Turkey’s Zorlu Enerji, has commissioned the 65.5 MW second unit of its US$320 million Kizildere III plant on the border between the southwestern provinces of Aydin and Denizli.

With the second unit now generating the plant currently has an installed capacity of 165 MW – making it the largest in Turkey.

The company also holds a so-called “pre-licence” for the 50 MW Alasehir III geothermal plant, for which it held a public consultation meeting last month, in line with the requirements of the environmental impact assessment submitted for the plant. The project is currently under consideration by Turkey’s Ministry for Environment and Urban Affairs.

PNNL and Oregon State University researchers will explore the potential of volcanic heat for energy
Two geophysicists noted for their work to harness the underground heat from volcanoes to produce electricity began joint appointments at each other’s institutions in January. The dual appointments enable GRC Member Alain Bonneville, Pacific Northwest National Laboratory (PNNL), and Adam Schultz, Oregon State University, to increase their collaboration on current and proposed projects, including traveling to each other’s institutions to share their insights and mentor students and interns.

A particular focus for the two colleagues is finding the most effective ways to extract underground heat from the Newberry Volcano in central Oregon. Newberry is one of the largest geothermal heat reservoirs in the western United States. A public-private consortium, Newberry Geothermal Energy (NEWGEN), is developing a research observatory on geothermal energy at the volcano, drilling high-temperature wells. The project aims to test more efficient, less costly, and innovative ways to extract underground heat where conventional geothermal power generation isn’t possible. Bonneville, Schultz, and their colleagues have been developing innovative methods that use electromagnetic instrumentation, sensitive gravity meters, measurements of ground deformation, and new computer-aided modeling methods to look under the volcano’s surface.

Canada: Alberta Town Repurposing Oil & Gas Wells for Geothermal Energy

Why a Small Alberta Oil and Gas Town is Pursuing Geothermal Power (DeSmog Canada)

(Google Maps)
Like many towns across Alberta, the landscape around Hinton is a pincushion of oil wells. At the bottom of some of the deeper wells, temperatures can reach upwards of 120 degrees Celsius, and that geothermal heat could be about to spur the town on to its next energy windfall.

A plan is underway to pump water up from deep underground, capture the heat it brings to the surface, then re-inject that water into the ground. The captured heat could warm a dozen municipal buildings or even eventually provide electricity.

“That’s attainable, that’s not a huge technical challenge. The question is at what cost,” Jonathan Banks, a research associate in geoscience at the University of Alberta, told DeSmog Canada.

The town recently got $1.2 million in federal and provincial grants to explore the feasibility of the project, known as a Front-End Engineering and Design, or FEED, study. That should be complete by the end of the summer.

“If the FEED study shows that the project is viable…we could start building the system in the fall of 2018,” Banks says, cautioning that there are a number of unknowns, such as an uncertain regulatory process.

A big part of why newly elected town councillor Dewly Nelson thinks the oil-friendly residents should welcome geothermal to town? It all runs on the same infrastructure and knowledge as the oil and gas industry, making it an excellent way to make use of existing oilfields and some of the workers who have been hit by low oil prices.

“If it ever really takes off on a large scale in Canada, it will be because of oil and gas,” he says.
