European Geothermal Energy Council Publishes Action Plan (EGEC)

The European Geothermal Energy Council (EGEC) publishes a policy paper arguing its case for more renewable energy to be included in the EU Energy Plan.

The EU’s energy security is at risk. Europe is hugely dependent on fossil fuel imports, in particular on the natural gas used to cover its extensive heating demand.

With the increasing deployment of variable renewables, the EU electrical system requires more flexible generation. Natural gas as backup must be discarded: the more it is used, the more the EU is dependent on energy imports, and the more it moves away from achieving energy security.

With the new Energy Union, the only viable option to address this challenge is to improve energy efficiency and to replace fossil fuel consumption and imports with stable renewable energy sources in the heating and electricity sectors. Energy efficiency is not sufficient to solve such a long-standing structural problem.

Such a path requires political courage and structural reforms in the years to come. In order to prepare the ground, EGEC publishes today an action plan towards “Fuel switch to renewables in the heating and electricity sectors”. This paper provides case studies of how to switch fuel with different geothermal technologies and puts forward key recommendations to build a resilient Energy Union.

New Zealand is Embracing Renewable Power While Australia Goes Backwards (VICE)

The Wairakei Geothermal Power Plant. Image via Wiki Commons
As Australia further concretes its dependence on coal, New Zealand's recent investment in alternatives is already bearing fruit. Usually this time of year is wet and New Zealand's hydro-lakes would be full, but an unseasonably dry autumn has left reserves 30 percent lower than average. This would usually be cause for concern, but the country's backing of geothermal power means they're still pretty sweet.

The New Zealand Minister of Energy and Resources, Simon Bridges said the current geothermal renaissance puts the country in good stead to hit the target of 90 percent renewable generation by 2025. As Bridges boasted at the World Geothermal Congress, New Zealand is now the fifth largest geothermal power generator in the world.

Meanwhile, across the ditch in Australia, a country with more than five times the population and 28 times the land mass, the governing party seems increasingly fixated on fossil fuels.

Research Team Invents Electrical Power Converter for Renewable Energy (University of Arkansas)

Engineering researchers at the University of Arkansas have invented a novel electrical power converter system that simultaneously accepts power from a variety of energy sources and converts it for use in the electrical grid system.

The U.S. Department of Energy was granted a U.S. patent for the technology and is now seeking licensing opportunities for potential commercialization. The research was sponsored by a Department of Energy grant.

The availability and use of renewable energy sources, such as solar, geothermal and wind, and their associated harvesting systems increase the need for new power converters that can efficiently convert diverse energy sources to work across modern electrical grid systems. Current renewable energy conversion systems are bulky, inefficient and struggle to accept multiple inputs from diverse sources.

The researchers’ high-frequency matrix converter addresses these shortcomings. Its simplified control system uses power converters to allow connection of a variety of power sources to a small, high-frequency transformer. Then, using a high-frequency matrix converter, it produces stable electricity ready to be supplied to the electrical grid system.


Iceland Drilling Tapped for 40 MW Montelago Geothermal Project (Business World Online)

Emerging Power, Inc. (EPI) has tapped Iceland Drilling Corp. (IDC) to conduct drilling works for its planned 40 MW geothermal project in Oriental Mindoro.

The renewable energy company said in a statement over the weekend that Iceland Drilling Corp. will undertake the drilling activity for the $185-million Montelago project. Under a deal inked last April 20, IDC will drill at least two wells starting in July.

Iceland Drilling will use a Geysir Drillmec HH-20SS equipment -- a trailer mounted, fast moving, automatic, hydraulic rotary drilling rig with a drilling depth capability of 4,000 meters. The heavy-equipment has been previously used in a geothermal drilling project in Biliran.

Expected to be operational by 2016, the Montelago project straddles barangays Montelago, Montemayor and Melgar-B in the municipality of Naujan, Oriental Mindoro.

Geothermal Energy, Aluto Volcano, and Ethiopia's Rift Valley (The Geological Society of America)

Aluto is Ethiopia's main source of geothermal energy, a low-carbon resource that is expected to grow considerably in the near future. 

In their open access paper published in Geosphere this month, William Hutchison and colleagues present new data from Ethiopia's Rift Valley and Aluto volcano, a major volcano in the region. Aluto is Ethiopia's main source of geothermal energy, a low-carbon resource that is expected to grow considerably in the near future. Preexisting volcanic and tectonic structures have played a key role in the development of the Aluto volcanic complex and continue to facilitate the expulsion of gases and geothermal fluids.

Using high-resolution airborne imagery, field observations, and CO2 degassing data, the authors explore in great detail how these preexisting structures control fluid pathways and spatial patterns of volcanism, hydrothermal alteration, and degassing. Understanding these preexisting structures, they write, "Is a major task toward defining the evolution of rift zones and also has important implications for geothermal exploration, mineralization, and the assessment of volcanic hazard."

Lawmakers Hope to Lure Geothermal Lab to Newberry (KTVZ)

DOE research site would take 300 workers to build, 100 to operate

Central Oregon lawmakers have won their colleagues' backing in a bid to bring a lucrative federal geothermal research site to the flanks of the Newberry Volcano near La Pine.

State Rep. Gene Whisnant (R-Sunriver) sponsored and carried House Joint Memorial 19 (HJM 19) successfully on the House floor Thursday with a unanimous vote of passage.

HJM 19 urges the Secretary of Energy and Congress to site the U.S. Department of Energy's Frontier Observatory for Research in Geothermal Energy (FORGE) at the Newberry Geothermal Project in Deschutes County.

The FORGE will perform advanced research on enhanced geothermal systems for the purpose of developing large-scale, economically sustained heat exchange systems.

World Geothermal Congress 2015:

Melbourne Declaration from World Geothermal Congress 2015 

“Geothermal in Perspective – Views from Down Under” 

We are more than 1500 members of the global geothermal community, representing more than 75 countries, who have gathered together in Melbourne, Australia, for the World Geothermal Congress 2015. We share a common interest in geothermal resources, stimulated by the promises and challenges they present. Participants have shared in short courses and field trips in New Zealand and Australia, where geothermal development and preservation initiatives provide examples from which the rest of the world can learn. We acknowledge a debt to those before us who built a solid base of knowledge and experience, as we create better outcomes for energy efficiency and delivery around the world.

Advanced economies rely on the efficient and reliable availability of energy. The energy options we currently have can be considered gifts from our ancestors. We are responsible for their sustainable management so that our endowment of natural resources can continue to meet the needs of future generations. Geothermal energy sits within a suite of clean and sustainable energy options, providing benefits beyond simple energy delivery in terms of sustaining the health of the environment in which we live.

Geothermal resources soothe bodies, warm homes and hotels, and supply heat for commerce, industry and agriculture. They provide the clean raw fuel for an expanding base of electricity generation. New opportunities are opening for the harvesting of valuable minerals carried within geothermal fluids, and for understanding the extreme life forms that survive within these fluids. Geothermal resources are indigenous; they are sustainable; their use is environmentally responsible; their high availability is largely independent of weather and climate; they displace carbon-intensive energy resources. Geothermal energy can be considered a global resource. In some places, geothermal resources already provide the most cost effective option for power and heat generation, representing a sound financial investment choice.

In spite of this, only a small fraction of the global geothermal potential has so far been realized. Many people remain unaware of the geothermal options available to them or the costs and benefits associated with these. Financial, legal, institutional and regulatory hurdles are common. To overcome these hurdles:

We urge governments to implement policies that ensure that the environmental costs of all energy developments are internalized and reflected in their pricing;
We urge governments to implement policies to minimize legislative and administrative barriers to geothermal development;
We urge governments and finance agencies to work with national and international geothermal associations to disseminate accurate information about the technology, costs and performance of geothermal developments;
We urge all parties to respect the close association of indigenous peoples with geothermal features upon and beneath their traditional lands, where such traditional relationships exist, and to negotiate with these peoples in a fair manner;
We urge that substantial R&D funding be committed to decrease the cost of geothermal power, to extend geothermal production to lower resource temperatures and across a greater range of geological settings;
We urge that particular efforts be directed to breaking down the financial risk barrier that commonly delays drilling on new ‘green field’ geothermal projects;
Finally, we urge governments and academic institutions to cooperate to transfer knowledge from geothermally experienced to less experienced countries, through training and education, capacity building, and technical assistance.

Through these actions, our common goal is to improve the living standards of citizens of the world through the supply of indigenous, affordable, environmentally responsible energy for generations to come, while preserving a portion of geothermal resources in an undisturbed state for all time.

Why Invest in Italian Geothermal? (Volcanex)

(Addressing readers at WGC 2015): Australian investors seeking international renewable energy opportunities should consider geothermal energy in Italy. The European power market is rapidly transitioning towards renewable technologies under strong EU climate change and energy security policies and in certain countries local, climate-friendly, geothermal energy is making a significant contribution to utility-scale electricity and heating supplies. Australian familiarity with geological risk should be able to provide an investment boost.

Italy, in particular, offers all of the necessary components of successful geothermal power projects except for sufficient finance. While some of these components are more or less attractive compared to those in other geothermal countries their overall combination highlights Italy as a compelling geothermal investment destination.

Turning Bakken Oil Well Waste Water Into Clean Geothermal Power (Bloomberg)

Though the technology has yet to be applied broadly, early results are promising.

are being installed. Source: University of North Dakota, Will Gosnold via Bloomberg
Oil fracking companies seeking to improve their image and pull in a little extra cash are turning their waste water into clean geothermal power.

For every barrel of oil produced from a well, there’s another seven of water, much of it boiling hot. Instead of letting it go to waste, some companies are planning to harness that heat to make electricity they can sell to the grid.

Companies such as Continental Resources Inc. and Hungary’s MOL Group are getting ready to test systems that pump scalding-hot water through equipment that uses the heat to turn electricity-generating turbines before forcing it back underground to coax out more crude.


Senator Wyden Introduces Geothermal Energy Opportunities (GEO) Act (News Release)

As part of his continued work to find new ways to fight climate change while lowering energy prices for U.S. consumers, Senator Ron Wyden, D-Oregon, today introduced a pair of bills that would boost domestic clean energy production and reduce carbon emissions.

The Geothermal Energy Opportunities (GEO) Act, encourages geothermal energy production by breaking down barriers that prevent prospective geothermal projects from getting in the ground.

The geothermal bill introduced today helps would-be geothermal developers explore for and develop geothermal resources through a public-private grant program. As part of the partnership, developers report their findings, contributing to a nationwide map of geothermal potential that will reduce the risk and drive down the cost of geothermal energy for the future. The bill also makes it easier for oil and gas developers to co-produce clean geothermal energy on federal lands under existing leases.

Additionally, the bill incorporates legislation Wyden introduced earlier this year – the Geothermal Production Expansion Act – to prevent speculative bidders from unproductively driving up the price of leases for developers seeking to use land productively for geothermal projects. The bill streamlines the federal geothermal leasing program by allowing for the non-competitive leasing of a limited amount of federal land at fair market value to spur the expansion of geothermal energy on already identified “hot spots.”

Geothermal Hopes Stall Without City Backing (kucb)

A years-long effort to bring geothermal power to Unalaska may be on its last legs. The city government is draining its accounts for exploring Makushin Volcano, saying the project is too expensive and risky to pursue any further.

"Right now, it’s just pretty much a dead project," says city public utilities director Dan Winters.

Winters says the city is clearing out its geothermal savings. They’ve transferred an expiring federal grant to Akutan, and rolled their local match back into the city’s general fund. And soon, the state Legislature will likely take back the rest of the geothermal account -- a $1.5 million grant that was never used.

For now, though, they’ll shop Makushin around to private companies alone -- and wait for a chance to bring the city back on board.

Using Geothermal Solutions to Desalinate Oil Field Water (Renewable Energy

 Cathy Chickering Pace (GRC Member), SMU Geothermal Lab

Clean water — it’s a precious resource in hot demand right now, for more than taking a shower or watering our crops. The United Nations projects the world’s population will grow by another billion people, to 8.4 Billion, by 2030. More people means more need for food, water, electricity, and other necessities. Beyond the obvious demands for water, our increasing appetite for electricity also requires water — and plenty of it. Most of the electricity generated in the U.S. uses water in some capacity.

When the Sierra Nevada snowpack is at 65 year low, there will be serious water shortages in California  that can affect us all.  Droughts can be powerful motivators for innovative water efficiency and conservation measures, and have led to the development of innovative technologies, such as desalination of brackish ground water, produced oil field water, or seawater.  Certainly these technologies hold tremendous promise, particularly in places where high salinity waters outweigh the freshwater supply significantly — places like Texas, where brackish water is produced from oil and gas wells.

Low Hydro Levels No Threat - Geothermal Energy More than makes Up the Difference (Radio New Zealand)

New Zealand electricity companies are cruising into winter relatively unfazed by low water levels in hydro lakes. Changes to the rules of the industry and heavy development of geothermal energy have given household electricity users a buffer against dry weather that they did not have in the past.

As much of New Zealand continues to enjoy an Indian summer, the dry conditions mean New Zealand's hydro lakes have only two-thirds of the water they usually have at this time. Not much water is flowing in to replenish them - only 70 percent of the seasonal average.

Official statistics show the boom in geothermal electricity is helping. In six years, more than $2 billion was invested in geothermal electricity, doubling its capacity to over 1000 megawatts. And since the earth's core is always hot, electricity can be constantly produced using geothermal tools, no matter what the weather.

Direct Utilization of Geothermal Energy 2015 Worldwide Review

Presentation made by John W. Lund and Tonya L. Boyd at the World Geothermal Congress

 Summary of the various categories of direct-use worldwide for the period 1995-2015.

This paper presents a review of the worldwide applications of geothermal energy for direct utilization, and updates the previous survey carried out in 2010. We also compare data from 1995, 2000 and 2005 presented at World Geothermal Congresses in Italy, Japan and Turkey, respectively (WGC95, WGC2000, and WGC2005).

An estimation of the installed thermal power for direct utilization at the end of 2014 is used in this paper and equals 70,329 MWt, almost a 45% increase over the 2010 data, growing at a compound rate of 7.7% annually with a capacity factor of 0.265.

Dajin Finds Significant Lithium at Known Geothermal Area (BayStreet)

Dajin Resources Corp. of Vancouver, Canada reports that the company's wholly owned subsidiary, Dajin Resources (US) Corp. has confirmed the presence of near surface lithium on Dajin's 100% owned Alkali Lake project in Esmeralda County, Nevada.

The property is located approximately 7 miles (12 km) northeast of Rockwood Lithium's Clayton Valley lithium operation, the only producing brine based lithium mine in operation in North America. The Rockwood Lithium operation was recently acquired by Albemarle Corp., the world's largest producer of lithium products, as part of a $6.2 billion transaction.

Like Clayton Valley, Alkali Lake is a classic, fault bounded closed basin where evaporation exceeds precipitation. Alkali Lake is in a known geothermal area and contains volcanic rocks with high lithium values. Just as with circulating basin waters, deep fluids, particularly hot ones associated with the geothermal resource, dissolve rocks, liberating boron, lithium and other elements such as sodium and chloride. These minerals are brought to the surface as springs emanating from the faults bounding the playa. The location of a closed basin in an arid environment with a geothermal system and plentiful sources of Lithium suggest that Alkali Lake may host significant Lithium rich brines.

Indonesian Government Gets Serious About Renewable Energy Development (Jakarta Post)

Estimated 28.8 GW of new geothermal energy potential

Following a major overhaul in the country’s fuel subsidy program, the Energy and Mineral Resources Ministry is now striving to explore new and renewable energy resources.

Indonesia is currently heavily dependent on fossil fuel, particularly oil and coal, despite possessing abundant potential sources of renewable energy, primarily geothermal and solar energy.

Located in the “ring of fire”, the country is rich with volcanoes providing abundant geothermal sources. In addition, the country also receives sunlight throughout the year, making it ripe for solar power development.

Despite this potential, efforts to exploit these resources have been few and far between.

China Could Get Most of its Energy from Renewables by 2050 (Environment & Energy Publishing)

Renewable energy could economically provide China the majority of its energy by midcentury, according to a new report.

The "China 2050 High Renewable Energy Penetration Scenario and Roadmap Study" from the China National Renewable Energy Centre models energy trends in China, stipulating a goal of high renewable energy penetration with the constraints of pollution, emissions, technology and economics.

The study found that wind, solar, hydropower, biomass and geothermal energy could produce 60 percent of China's total energy and generate 85 percent of its electricity in 35 years while maintaining stability on the grid.

Starting on this path would likely make China's greenhouse gas emissions peak sooner than 2030 under the climate change deal President Obama and Chinese President Xi Jinping negotiated last year.

Starting with science provides a valuable foundation for managers, policymakers, and other decision makers to make the most informed decisions to protect our changing world.

Deep within the Earth’s crust lies an extremely important but underutilized renewable energy resource: geothermal energy. In 2008, the USGS released a national assessment of geothermal power resources, showing more than 550,000 Megawatts–electric power–generating potential. Since then, the USGS has continued to research and assess geothermal power potential all over the country.

“Interest in geothermal energy has rapidly grown. Recent permitting activity has seen dozens of applications for geothermal leases. All of this is based on the fundamental resource assessment efforts of the USGS – without that basic research, the benefits of this renewable energy resource would be achieved much more slowly and at much greater expense.” — GRC Member William Glassley, Department of Earth and Planetary Sciences, University of California, Davis.

Science & Technology:

What if we transformed carbon dioxide from being a waste product into being a huge battery to help even out our energy supply? We could make carbon storage pay off, while solving problems of intermittent energy supply from renewables.

So say Tom Buscheck from the Lawrence Livermore National Laboratory in California and his colleagues who presented a design for this type of energy storage at the European Geosciences Union general assembly last week in Vienna, Austria.

Their design would be able to store the excess energy produced by renewable and conventional power sources when demand is low and, at the same time, lock up the major cause of global warming – carbon dioxide.

"The only way you can decarbonise the fossil-fuel energy systems is if you can devise an approach where the economics makes sense," says Buscheck, who thinks their design, which is funded by the Geothermal Technologies Office at the US Department of Energy, does just that.

Buscheck team's proposes storing that excess energy in two forms: pressure and heat. Excess electricity would power a pump that injects supercritical CO2– a hybrid state of liquid and gas – into underground brine in sedimentary rocks between 5 and 10 kilometres below the surface. Supercritical CO2 can drive turbines much more efficiently than steam and can take a lot of squeezing and heating – improving its capacity to store energy.

USA, Hawaii:

University of Hawaii to Start Hualalai Geothermal Study (KITV Honolulu)

In search of a natural power source on the Big Island the University of Hawaii gets the green light to conduct a hi-tech geothermal study.

KITV4's Mike Cherry reports how it could lead to man-made activity on another big island volcano.

The project is funded by the U.S. Department of Energy and the state Department of Land and Natural Resources, researcher Nicole Lautze, with the Hawaii Institute of Geophysics and Planetology, said in her application. Lautze said that the Hualalai exploration is the first exploration permit in what will be an overall effort referred to as the “Geothermal Resources Exploration Plan for Hawaii.”

PetroEnergy Looking for Other Geothermal Sites on Luzon (BusinessWorld Online Edition)

Following the successful operations of its first energy venture, listed firm PetroEnergy Resources Corp. (PERC) is now setting its sights on other sites that can support more geothermal energy projects.

“We are looking at other areas in Luzon for other geothermal projects,” PERC Vice-President Francisco G. Delfin, Jr. said during a plant tour on Wednesday last week. “Why Luzon? Because the power market is still here. There’s a huge potential here,” Mr. Delfin added.

The official said studies and internal discussions on the next project are ongoing but noted that “everything is very preliminary.”

PERC, through 65%-owned Maibarara Geothermal, Inc. (MGI), owns and operates a 20-MW geothermal plant in Sto. Tomas, Batangas. MGI is also in the process of expanding the power plant by another 10 MW, which would entail an investment of up to P1.3 billion.

New Geothermal Energy “Shortcut” Could Be Global Energy Game Changer (CleanTechnica)

GOCE Free Air Gravity Disturbance Map

If you don’t know your free air gravity from your Bouguer maps, now is a good time to find out. When combined, the global maps form a one-two punch that could knock the geothermal industry out of the ballpark, so to speak.

Although the geothermal industry has stalled out here in the U.S., globally, the geothermal energy sector has been growing steadily, and the two maps provide a tool that could cut way down on exploratory expenses and help the industry really take off.
