Canada: "Geothermal Offers Potential in the Mid to-Long Term" - Report

Canada submits Mid-Century Strategy for a Clean Growth Economy (News Release)

Last month, the Minister of Environment and Climate Change, Catherine McKenna, announced Canada's Mid-Century Long-Term Low-Greenhouse Gas Development Strategy, at COP22 in Marrakech, Morocco, making Canada one‎ of the first countries to do so.

The mid-century strategy describes various pathways for innovative and creative solutions consistent with our international goal of holding the global average ‎temperature rise to well below 2°C, while pursuing efforts to limit the temperature increase to 1.5°C, as called for in the Paris Agreement. The strategy focuses on meeting climate-change objectives and enabling growth, requiring significant long-term investments in infrastructure to support transformation to a low-carbon economy.

Regarding geothermal energy the report states that "Other renewable energies offer potential in the mid to-long term. For example, generating zero-emitting
electricity with geothermal power is possible using hot subsurface water or steam coming from underneath the earth’s surface. Standard well drilling technology
can provide access to high temperature sources and power to turbines that offer reliable electricity. 

USA, California: Geothermal Energy Can Help Reduce Greenhouse Gas Emissions in the Golden State

California air regulator rolls out draft plan to achieve 2030 climate goals (Utility Dive)

The California Air Resources Board (ARB) last week issued an initial draft plan to meet the state's ambitious 2030 climate goals, leaning on existing standards and requirements to achieve emissions reductions, Carbon Pulse reports.
California plans to reduce greenhouse gas emissions by 40% below 1990 levels by 2030, which the state says is the "most ambitious target in North America."

California ARB's plan includes the state's efforts to put more fuel-efficient cars and zero emission vehicles on the road, utilize low-carbon fuels and renewable energy, cap-and-trade carbon regulations, waste diversion from landfills, water conservation and improvements to energy efficiency in homes and businesses.

Enel S.p.A., through its subsidiary Enel Green Power North America, Inc. (EGPNA), has started operations at the world’s first integrated, commercial-scale geothermal-hydro power plant at its Cove Fort site in Utah. At Cove Fort, EGPNA added a fully submersible downhole generator technology to a geothermal injection well, combining geothermal and hydroelectric power at one site.

Findings from the initial testing phase held between July and September 2016 reveal that the addition of the hydro generator to the geothermal injection well resulted in an overall increase in output of 1,008 MWh over this time, offsetting the energy consumption of the Cove Fort plant by 8.8%, therefore improving the plant’s operational efficiency.

The innovative generator technology captures the energy of the water flowing back into the earth to generate additional electricity while also better controlling the flow of brine back into the ground. The presence of the generator creates pressure against the brine flow, which reduces the flow’s turbulence into the well, hence minimizing the likelihood of any potential damage to the well. The result is a first-of-its-kind innovation that can reduce operational and maintenance expenses, while also having the potential to generate additional revenues.

USA, California: Exploring Long Valley's Geothermal System

Mapping Water and Heat Deep Under Long Valley Caldera (EOS)

Researchers use electrical resistivity to find the heat source and reservoir feeding Long Valley Caldera's labyrinthine hydrothermal system.

View of part of the Long Valley Caldera with Mono Lake in the background, taken from the summit of mammoth Mountain. Taken by Ian Crawford, GRC Fieldtrip September 2015.
Long Valley Caldera is a volcanic depression near Mammoth Mountain in California, which has experienced extensive hydrothermal activity over two periods of time since it formed about 767,000 years ago. The caldera is home to an active hydrothermal system, which has been extensively studied close to the surface but less well characterized deeper underground. Hot fluids flow underground and escape to the surface through hot springs, but the heat source and reservoir for the labyrinthine hydrothermal system have not been thoroughly studied.

Now, Peacock et al. have used magnetotellurics to create a three-dimensional (3-D) model of the ground down to 10 kilometers underneath the Long Valley volcanic system. To create this 3-D model, the team measured the Earth’s electrical response to natural magnetic fields at 61 stations across Long Valley Caldera.

Canada: Exploration Drilling at Valemount Geothermal Power Project to Start Soon

British Columbia’s First Geothermal Power Project Could Be Weeks From Drilling (CleanTechnica)

Alison Thomson, a director of Borealis GeoPower, explained, “This is a private industry-led initiative, although the federal government has funded some of our exploration work. This is the first time that geothermal wells have been drilled to serve a nearby customer.”

Borealis plans to build a geothermal industrial park that will initially supply the village of Valemount, in the province’s Robson Valley region, with carbon-free heat (substituting for propane gas and diesel). Eventually, GeoPower will also supply the electricity.

“We’ve completed field work in each of 2010-2016 which has aided in the reservoir delineation. We have now chosen our drilling targets and requested drilling permits from the government. We are participating in a private placement to finance the drilling and development of the reservoir,” said Thomson.

Philippines: Minister Suggests Competition for Baseload Energy Supply

DoE: Dumping fuel mix policy boosts baseload competition (BusinessWorld)

Energy Secretary
Alfonso G. Cusi
The Philippines Department of Energy (DoE) has maintained its position that it will abandon a fuel mix policy that sets a “quota” for each energy technology, saying developers should be left to decide the kind of power plants they want to build based on the country’s power system requirements.

Energy Secretary Alfonso G. Cusi said industry participants should not expect a fuel mix policy similar to what was adopted by the past government, which aspired to limit the sourcing of new power capacity to no more than 30% for coal, 30% for natural gas, 30% for renewables and 10% from other sources including diesel-fired plants.

Mr. Cusi said on his watch, industry should get used to a mix that set by a system requirement of 70% baseload provided by plants running on coal, natural gas and geothermal power on a 24-hour basis, 20% mid-merit and 10% peaking power.

Kenya: Stake of Minority Shareholders in Kengen has Been Substantially Diluted

State ups its stake in KenGen to 74pc (The Standard)

The Kenyan Government has increased its shareholding in the Kenya Electricity Generating Company (KenGen), firming its majority owner's grip on the power generator. The State's shareholding increased to 73.92 per cent as of June 2016 from 70 per cent in June 2015, after a rights issue in June this year.

The National Treasury, which holds the Government ownership in KenGen, converted a Sh20.2 billion debt into equity, which had the effect of pushing up its shareholding. Treasury now owns 4.62 billion shares out of the total 6.24 billion shares.

At the same time, the stake of minority shareholders in the company has been substantially diluted, after the rights issue. KenGen, in its annual report for the year to June 2016, said the over 192,000 shareholders held a 14 per cent stake by close of the financial year, compared to 26.78 per cent that was in their hands as of June 2015.

USA, California: "The geothermal-lithium angle could be just the ticket."

US Energy Dept. Toots Geothermal Horn, With Lithium Bonus (CleanTechnica)

(Courtesy Simbol Materials)
The Energy Department is very excited about its California lithium project piggybacked onto a geothermal power plant, and with good reason. Lithium is the key ingredient in innumerable electronic devices, from portable gear on up to EVs and large scale lithium-ion energy storage systems.

The problem is — or has been, until now — that the US does not have much of a domestic lithium supply.

Wherever US energy policy may go under the incoming Trump Administration, if the President-elect is serious about bringing manufacturing back to the US he’ll have to demonstrate a bit more of a forward-looking strategy than bribing US companies to keep a few hundred jobs here and there, let alone create new jobs. The geothermal-lithium angle could be just the ticket.

USA, California: Geothermal Resources Can Play an Important Role in the Salton Sea’s Restoration

How Salton Sea's Geothermal resources could help save it (The San Diego Union-Tribune)

by Bill Corcoran, Western Regional Campaign Director, Sierra Club & Nick Segura, business manager for IBEW 569.

The Salton Sea region has some of the best and largest geothermal resources in the United States. According to the National Renewable Energy Laboratory, at a minimum there is a potential for at least 1,350 megawatts of new geothermal to be developed at the Salton Sea by 2030.

Geothermal resources can play an important role in the sea’s restoration. This clean energy resource is reliable and will reduce the need to burn more fossil fuels. On top of cutting climate altering pollution, geothermal projects can cover exposed playa, which will reduce dust emissions that damage the lungs of all who lives in the area. In addition to cutting emissions over the long-term, geothermal energy will provide steady power when other clean energy resources ramp down. Additionally, the massive amounts of geothermal potential brings incredible opportunities to create career paths into good middle-class jobs with family health care, skilled apprenticeship training and pension retirement. 

If we build out just 500 megawatts of geothermal, it will create millions of works hours in construction, operations and maintenance jobs for a region that suffers from a 21 percent unemployment rate. The taxes and other revenue sources will help local governments.

Europe: Current European Commission Proposal Suppresses the EU-wide Definition of “Geothermal” - EGEC

EGEC Reaction to the Clean Energy Package (EGEC)

The European Geothermal Energy Council gives a tepid welcome to the EU Commission’s proposals for the revision of the EU energy framework.

The European Commission unveiled the “Clean Energy Package” including, amongst other things, the revision of the directives on Renewable Energy (2009/28/EC), the Energy Performance of Buildings (2010/31/EU), Energy Efficiency (2012/27/EU), and the design of the electricity market.

The package is by no means a great leap forward. It lacks ambition and deals serious blows to renewable power, by withdrawing measures such as priority dispatch. Moreover, the current proposal suppresses the EU-wide definition of “geothermal”, which is a negative step backwards for the European market in
geothermal-related equipment and services.

The Commission states a strong support to increasing the share of renewables in the building and the heating and cooling sectors; yet it shies away from binding measures for faster development. Even worse, loopholes under energy efficiency legislation still allow support to new fossil-based heating equipment.

EGEC therefore urges the European Parliament and the Council to build on this package to put the European Union back on track towards its commitment to becoming the world number one in renewable energy.

Canada: Plans to Harness Geothermal Energy From Producing Oil Wells -- A First in Canada

WellStar Energy Corp. Signs LOI to Acquire Sundial Energy Ltd. Plans to Harness Geothermal Energy From Producing Oil Wells -- A First in Canada (News Release)

WellStar Energy Corp. of Calgary, Alberta, advises that the company has entered into a Letter of Intent dated November 25, 2016 in connection with the acquisition of Sundial Energy Ltd. which represents an undivided 100% interest in its assets and intellectual property. Sundial is involved in the field of geothermal heating applications, LED lighting and solar power generation.

WellStar, at its McTaggart, Saskatchewan oil project produces in excess of 1,200 barrels per day of oil and water that at surface is approximately 50 degrees Celsius. Currently, the produced oil and water are gravity separated, then the produced hot water is pumped into the company's onsite disposal well, leaving a significant resource of unutilized geothermal heat.

The excess heat in the volume of liquids produced from the company's oil wells at its McTaggart project is rare but not unique. The company believes that existing pumping oil wells that produce significant heat can be used as a source of energy for many applications. The acquisition of Sundial Energy with its renewable energy expertise, will assist WellStar in developing the process to make use of this otherwise wasted resource.

South Korea: New Incentives Will Help Double Renewable Energy Output by 2025

S.Korea unveils new tariffs, incentives to boost renewable energy (Reuters)

(Courtesy CIA.gov)
South Korea plans to provide new incentives for renewable producers and consumers as its seeks to double power from green sources to 11 percent of the country's electricity supply by 2025 from 4.5 percent last year.

Seoul will implement a competitive market auction system for power producers as early as the first quarter of 2017, shifting away from the current feed-in-tariff system, the country's energy ministry said in a statement on Wednesday.

The new system means utilities can buy electricity from renewable power producers via tenders and fixed-price deals for up to 20 years - helping green energy producers ensure stable profits.

Canada: "The Oil Patch has Tremendous Geothermal Heat Resources"

The Oil and Gas Industry is in Hot Water (and That’s a Good Thing) (Oil and Gas Investments Bulletin)

(Courtesy CanGea)
Alberta’s oil and gas wells produce thousands of barrels of water each day. This water is considered a waste by the oil patch, and operators pay to send it away by pipeline or truck.
But what if that water had a value? Albertans spend a lot of money heating water with natural gas. And yes – natural gas is pretty cheap right now – but costs are about to jump $1 per GJ in 2017, and an additional $0.50 in 2018 due to carbon taxes. Delivered natural gas costs in Alberta could reach over $8-10 per GJ within two years.
And that means geothermally-derived gigajoules will become cost-competitive in certain markets. Hot salty brine, or “formation water”, produced alongside oil and gas at temperatures above 30°C, can be used in a variety of direct-use applications.

Turkey: Overview of the Technology Used in the 3.8 MW ORC Tosunlar 1 Geothermal Power Plant

Top Plant: Tosunlar 1 Akca Plant, Saraykoy, Denizli, Turkey (POWER magazine)

Owner/operator: Akca Enerji

POWER magazine today officially announced winners of its 2016 Top Plants in the renewable generation category. Among the six finalists is an ORC geothermal power plant in Turkey.

What sets the Tosunlar plant apart is that it uses a two-pressure ORC system with only one single-disk turbine. Typical binary systems use one turbine per pressure level, with the working fluid entering the high-pressure side after leaving the evaporator, before passing through the recuperator and the low-pressure evaporator (which draws heat from geothermal fluid after it leaves the high-pressure evaporator).

The 3.8-MW facility entered operation in June 2015 and has so far exceeded expectations, performing more than 10% above contracted results. The plant was awarded the European Geothermal Innovation Award by the European Geothermal Energy Council as the best innovation in the geothermal sector in 2016. A video of the project can be viewed below.

USA: "Geothermal is On Track for its Best Year Ever"

Renewable Energy in US Gained 24 Percent Through First Nine Months of 2016 (Renewable Energy World)

By Daniel Fleischmann

Quietly, geothermal is on track for its best year ever. Geothermal generation is on pace to generate over 17,000 GWh this year; an industry record and still the most any country has ever generated in one year. 

The U.S. Energy Information Agency (EIA) on Nov. 29 released electric generation statistics through the end of September 2016. Generation from geothermal, solar, and wind energy increased by 24 percent compared with the first nine months of 2015. Non-hydro renewable energy, including biomass, has made up 8.5 percent of U.S. electric generation thus far in 2016.

Overall, renewable energy sources, including hydro-electric power, made up 15.1 percent of total U.S. electric generation through the first nine months of 2016. This is down from 16.9 percent during the first half of 2016 (with 9.2 percent from non-hydro renewables), but still far ahead of 2015. Non-hydro renewable energy is still expected to be over 9 percent of total generation by the end of the year, up from 7.6 percent in 2015.

Kenya: Silica and Lithium Could be By-Product from Geothermal Power Plants

KenGen eyes sale of valuable minerals in geothermal fluids (Business Daily Africa)

The Kenya Electricity Generating Company (KenGen) is eyeing the sale of valuable minerals such as silica and lithium found in geothermal fluids as a strategy to diversify its revenue base.

The State-owned power generator is seeking a consultant to assess the feasibility of extracting minerals from the hot brines — the waste stream that geothermal power plants pump out of the ground.

KenGen managing director Albert Mugo said the firm is turning to innovation to exploit the minerals found in geothermal fluids which come from rocks below the earth’s surface.

“We want an expert to establish the technical and financial viability of this project.” Mr Mugo told the Business Daily. He declined to offer any timelines or capital commitments, saying it is still “very early” in the project cycle. “If found feasible, we’ll go ahead,” he said.

New Zealand: Commercial Operation to Extract Silica from Geothermal Power Plant Wastewater

First Silica Extraction Plant Almost Complete

Environmetals Limited (EVM) is presently engineering the first commercial application of its technology to extract silica from geothermal-electricity-waste fluids. After operating successful pilot plant operations to produce colloidal silica at two geothermal fields at Wairakei NZ and Kawerau NZ, EVM is now preparing to build and install the first 5,000 tpd commercial extraction plant at Kawerau. This is expected to be completed later in 2016. It should be noted that the pilot plant was not a sub-scale plant but rather a sub-module of the commercial plant, so reaching scale involves adding additional sub-modules.

EVM’s extraction and processing equipment removes silica from the waste geothermal fluids (after the generation of electricity) and creates colloids in the range of 8 – 16 nanometres with a concentration of 30 – 40% silica by weight. Three provisional patents have been filed covering all EVM developments over the last five years, creating a robust Intellectual Property platform.

Geothermal electricity generation is predicted to grow as a renewable energy resource, but the presence of dissolved silica in geothermal fluids can be a limiting and costly issue for the power plant.

Indonesia: Kamojang Unit I Geothermal Plant to Resume Operations October 2017

Kamojang unit I geothermal plant to operate in October next year (Jakarta Post)

Kamojang unit I geothermal plant in Bandung, West Java, is expected to resume operations in October next year following its turbine damage in April 2014, an official has said.

Pertamina Geothermal Energy's (PGE) Kamojang plant maintenance manager Faiq Kautsar attributed the damaged turbine to its expired shelf life, saying that the turbine had been operating 32 years past its shelf life.

Faid was quoted by Antara news agency as saying that the replacement and building process of the geothermal turbine needed more time compared to conventional ones as the turbine parts needed to be compatible with geological substances.

New Zealand: Scientists Investigate Sudden Geyser Eruption in Rotorua

What lies beneath: Delving beneath Rotorua's bubbling surface (New Zealand Herald)

The spectacular eruption of a geyser near the shores of Lake Rotorua comes as scientists are discovering stunning new insights into the city's famous geothermal backdrop.

Scientists say there isn't any evidence to link the eruption - which sent water gushing up to 30m into the air near Rotorua's Ohinemutu village early on Monday - with this month's earthquake activity.

GNS Science volcanologist Brad Scott said it was also too early to draw any connection with the gradual return of surface features within the Rotorua Geothermal Field that has followed the closure of bores in the 1980s.

Indonesia: Italy Wants to Cooperate in Developing Geothermal Energy

Italy to invest more in Indonesia (Jakarta Post)

Former Italian prime minister Enrico Letta conveyed Italy’s interest in boosting economic ties and investing more in Indonesia in Jakarta on Monday. Letta founded the Italy-ASEAN Association and was prime minister of Italy from 2013 to 2014.

“Next year, we want to invest more in Indonesia. We are not troubled [by domestic matters in Indonesia] and we are sure that Indonesia can overcome this present turbulence,” said Letta, adding that Italian companies were very much interested in investing in various sectors, including in infrastructure, energy and automotives.

“Our country is at the top with geothermal renewable energy technology. So we think that we can have very good joint cooperation in this area. We want to help them invest, not to sell goods only,” he said. 

USA, California: Ormat Gets New PPA for 35 MW Ormesa Geothermal Power Plant

Ormat Technologies Signs 25-year Power Purchase Agreement for the Ormesa Geothermal Complex in California (News Release)

New PPA to Further Reduce Exposure to Natural Gas and Improve Margins

Ormat Technologies, Inc. today announced that its subsidiary entered into a 25-year Power Purchase Agreement (PPA) with Southern California Public Power Authority (SCPPA) to deliver electricity from its Ormesa geothermal complex in Imperial Valley, California beginning November 30, 2017.

The SCPPA PPA will supersede Ormesa’s current 30-year Standard Offer Contract No. 4 (SO#4) with Southern California Edison that has a variable energy rate tied primarily to volatile natural gas prices and that will expire on November 29, 2017. Under the terms of the PPA, energy from the Ormesa complex will be sold to SCPPA at a rate of $77.25 per megawatt hour with no annual escalation. Contract capacity is 35 MW, with a maximum generation equivalent to a net capacity of about 43 MW. SCPPA will resell about 86% of this power complex’s output to the Los Angeles Department of Water and Power (LADWP) and the remaining 14% to the Imperial Irrigation District (IID).
