USA: Report - "Geothermal lacks strong policy support and faces high development costs

Clean energy delivers for America—more jobs, increased economic growth, greater energy productivity and fewer emissions (Business Council for Sustainable Energy)

The 2018 edition of the Sustainable Energy in America Factbook – produced for the Business Council for Sustainable Energy by Bloomberg New Energy Finance, provides up-to-date, accurate market information about the broad range of industries — energy efficiency, natural gas and renewable energy— that are contributing to the country’s move towards cleaner energy production and more efficient energy usage.

After building no new geothermal plants in 2016, the U.S. added the 24 MW Tungsten Mountain plant in 2017. Unlike many other renewable resources, geothermal projects have long project completion periods of 4-7 years. In addition, the technology lacks strong policy support and face high development costs. These factors contribute to the low build volumes.

Another key area of activity within U.S. geothermal is hybridization – the combination of geothermal with another technology to enhance output. Two such facilities by Enel Green Power began operation in 2016. The first was at its
Stillwater plant in Nevada, where photovoltaic and solar thermal have been integrated into the geothermal plant. The second project added a hydroelectric generator into an injection well at Enel’s existing Cove Fort geothermal power plant in Utah.

Education: Some Interesting Facts About Geothermal Energy

5 Things to Know About Geothermal Power (EERE/GTO)

Midnight Heat, by Hreinn Hjartarson, Husavik, Iceland.
GRC Photo Contest 2017 - Honorable Mention
Here are some interesting facts about geothermal energy.
  1. Baseload energy - it’s always on: Geothermal power plants produce electricity consistently, running 24 hours a day, 7 days a week. The power output of a geothermal power plant is highly predictable and stable, thus facilitating energy planning with remarkable accuracy. Geothermal power plants are also an excellent means of meeting baseload energy demand, or the minimum level of demand on an electrical grid during a 24-hour period.
  2. Geothermal energy can heat, cool, and generate electricity: Geothermal energy can be used in different ways depending on the resource and technology chosen—heating and cooling buildings through geothermal heat pumps, generating electricity through geothermal power plants, and heating structures through direct-use applications. While geothermal power generation is mainly concentrated in the western U.S., these applications will help expand geothermal energy use geographically.
  3. Over 100 years of geothermally sourced energy: The first ever geothermal plant was set up in Larderello, Italy, in 1904. Steam from that geothermal source was used to turn a small turbine which powered five light bulbs. Today, the U.S. leads the world in geothermal power generation, providing more than 3.7 GW to the national grid. In fact, the first modern geothermal district heating plant was developed in 1892 in Boise, Idaho. DOE supports direct-use efforts, striving to heat more homes and reduce more energy bills.
  4. The largest geothermal plant in the world is located in California: The Geysers Geothermal Complex located north of San Francisco, California, is comprised of 18 power plants and is the largest geothermal installation in the world.  DOE funding at Calpine Corporation’s Caldwell Ranch site at the Geysers is a first-ever reopened abandoned steam field, validating universally applicable technologies.
  5. Geothermal can be closer than you think: Research funded by the Geothermal Technologies Office seeks ways to tap into geothermal resources across the nation. Traditionally, geothermal resources are most accessible in the western states, from Colorado and New Mexico up to Utah, Nevada, Idaho and Oregon. However, with the development of enhanced geothermal systems (EGS) technologies and additional research in deep direct-use (DDU) capabilities, geothermal energy will potentially be accessible across the country.

Kenya: Royalty for Geothermal Producers Proposed

Kenya Proposes Royalty for Geothermal Producers in Energy Bill (BNA News)

Kenya will introduce a royalty for geothermal power producers under a proposed new law.

Fees would be levied at a rate of 1 percent to 2.5 percent of revenue generated from the energy source within the first decade of a geothermal license being issued, according to the draft Energy Bill presented to lawmakers Feb. 14. The levy will then climb to between 2 percent and 5 percent, the bill states.

Eastern Caribbean: Big Potential for Geothermal Energy Development

Montserrat’s Geothermal Energy “gold mine”? (Montserrat Reporter)

Bruce L Cutright of Thermal Energy Partners (TEP) of Texas suggests that Montserrat’s accessible geothermal energy resource is potentially 100 MW.

An initial development would be likely to be 3-5 MW. (Montserrat’s current peak electrical load is a bit over 2 MW.)

Mr. Cutright also indicated that in neighbouring Nevis, TEP has helped to identify a geothermal resource of 100 – 400 MW and is working with the Government of Nevis in a partnership to develop geothermal energy there. (Official sources there suggest 300 MW and there are indications that some estimates are as high as 650 MW.) The proposed initial plant size there is to be 9 MW. 

Encouraged by developments in Nevis, the Government of St Kitts-Nevis is also looking to develop identified resources in St Kitts and to explore interconnectivity with Nevis as well as possibilities for export. Such export will require undersea power cables, which will therefore be within a few dozen miles of Montserrat.

A September 3rd 2016 Carib Journal article indicates that the Government of Antigua and Barbuda has also signed a memorandum of agreement with TEP towards developing a Organic Rankine Cycle geothermal plant with ten million watts of capacity.

USA: White House Request for Energy Efficiency and Renewable Energy a 66 Percent Decrease from 2017 Budget

Trump seeks clean energy cuts, $2 billion nuclear spending boost for Energy Dept. (Washington Post)

The Trump administration’s fiscal 2019 budget might never become law, but it’s a declaration of intent, and it would reshuffle priorities at the Energy Department, boosting outlays on nuclear security and slashing spending on renewables and energy efficiency.

Overall, the administration is asking Congress for $30.6 billion for the Energy Department, a 1.3 percent increase from fiscal 2017. That includes $1.6 billion added to the department’s budget after a last-minute spending deal was reached in Congress last week.

At the same time, the administration is asking for deep cuts elsewhere, especially in the agency’s Office of Energy Efficiency and Renewable Energy. The budget requests $696 million for that program, a 66 percent cut from the 2017 budget. That number includes $120 million added back after the recent two-year budget accord. The budget deal two weeks ago also meant that OMB restored $1.2 billion to science programs that would have been cut deeply.

Spain: Potential of Geothermal Energy to Power ​Canary Islands

​Canary Islands Exploring Potential of Underground Geothermal Energy (Canary Islands Report)

The Tenerife Government is proposing that the Spanish Government undertakes drilling exploration to identify the potential of geothermal energy in the Canary Islands, and the only region in Spain where this could possibly exist, but requires around 20 million euros to explore the subsoil.

This motion is presented with the support of all political groups represented in the Tenerife Government, but similar initiatives are being simultaneously presented in Gran Canaria and La Palma, because these three islands specifically have previously made joint efforts to evaluate the geothermal potential of the Canary Islands with direct involvement, but with little success in support from the Spanish Government.

It is suggested that three drilling sites should be sufficient for Tenerife geothermal energy exploration with a third of these costs covered by the island government, one third covered by a private initiative that has an interest, and the need for state aid to cover the final third of costs.

Science & Technology: Accurately Measuring Geothermal Flow

Striving For Perfection: Flow Energy Partnership Improves Geothermal Energy Production (New Release)

(Courtesy Sierra Instruments, Inc.)
Geothermal power companies need a water flow meter to accurately measure the  movement of the geothermal resource out of the ground and then back in - critical for assessing the efficiency of energy production.

To solve this water flow measurement problem, the energy company contacted, Elekon, one of Sierra Instruments, Inc.’s partners in Turkey. They originally specified an an electromagnetic flow meter to measure the water before it travels back into the earth to be reused.  However, Elekon’s,  Robert Benbanaste (CEO/Owner of Elekon), noticed right away that the pipeline size was too large for an inline electromagnetic flowmeter (over 48” for the line size). Robert had the perfect solution for this application. Sierra’s 241i insertion vortex flow meter.

Iceland: Expansion of Bitcoin Mining Offers Opportunities for Geothermal Energy

How Iceland became the bitcoin miners’ paradise (The Guardian)

The island nation is the first to use more electricity on mining crypto-curriencies than on its households – thanks in part to its magma-fuelled power plants.

Bitcoin’s price may be down more than 50% from its highs in December, but no one has told Iceland, where the cryptocurrency and its offspring are reshaping the economy.

According to Johann Snorri Sigurbergsson, an employee of the energy company HS Orka, Icelandic cryptocurrency “mining” is likely to double its energy consumption to about 100 megawatts this year. That is more than households use in the nation of 340,000 people, according to the national energy authority.

Why is Iceland so popular? The answer is simple: location, location and volcanoes. Volcanoes provide Iceland with a cheap and abundant form of renewable energy. Geothermal and hydroelectric plants abound on the island, driving down the wholesale cost of power, which lets bitcoin miners make higher profits as they run their computers 24/7, 365 days a year.

USA: Opportunities for the Geothermal Energy Industry to Produce Hydrogen Fuel?

There Are 39 Publicly Available Hydrogen Fueling Stations in the United States (DOE)

Yesterday we reported on a project to pilot the commercial production of hydrogen using renewable geothermal energy in New Zealand.

I thought it would be interesting to look at opportunities for the geothermal energy industry to help produce this increasingly popular fuel elsewhere. A recent survey from the U.S. Department of Energy listed current Hydrogen Fueling Stations in the USA.

As of January 25, 2018, there are 39 publicly available hydrogen stations for fueling fuel cell electric vehicles (FCEVs) in the United States—35 in California, 2 in South Carolina, and 2 in the Northeast. Another 29 public stations in California and 5 in the Northeast are planned.

Most of the hydrogen stations are located in the San Francisco and Los Angeles metropolitan areas very close to the important geothermal fields of The Geysers and by the Salton Sea.

Could this be an opportunity for the geothermal energy industry?

Science & Technology: Geothermal Heat from Flooded Coal Mines an Excellent Source for District Heating

Coal mines as energy storage (Utility Week)

As mines are abandoned, pumps switched off and mines flood. Geothermal heat, transmitted from the earth's centre find the mining legacy ideal conduits and warms this mine water to temperatures typically 20-40°C. Calculations suggest that the flooded mine workings are now a source of heat – with an estimated 2.2 million gigawatt hours of harvestable heat being produced per annum. That is enough to heat five times the number of homes in the UK, and with over one quarter of UK homes being in the coalfields the opportunity is enormous.

Mine heat is low grade, which means it is unsuitable for generating electricity as steam, but ideal for cost effectively heating homes, warehouses, leisure centres and offices. With approximately 45 per cent of heat in England and Wales used for heating, and 55 per cent in Scotland, this is a significant proportion of UK energy demand. To harvest the heat requires the use of heat exchangers and pumps. These work the same as the refrigerators we have at home. They use electricity to remove heat and cool the heat source.

Netherlands: Well at Westland Trias Geothermal Greenhouse Heating Project Reaches 4,100 Meter Depth

Triassic drilling almost reached final depth (T&A Survey Group B.V.)

Well reaches 13,451 feet or 4,100 meters depth

The drillings for the Trias Westland geothermal project have reached the Triassic layer. The third section was completed at the end of January. The casings have been placed and the borehole has been firmly cemented. This was the most exciting section of the project and, despite a number of technical challenges, it was completed successfully.

Mid next week we expect to investigate the reservoir section. This is done with special measuring equipment lowered deep into the borehole. Among other things, the permeability of the rock, the chemical properties of the water and the strength of the rock will be measured. With this information we can determine which filters should be used at the plant and at what pressure the cooled water can be injected. The production tests (also called well test) is expected to take place in the third week of February. Based on this information, in March we will decide whether the Triassic layer offers sufficient capacity.

Finance: Find Out How Combined Energy and Capacity Values of Geothermal Energy Significantly Exceeded the Value of Solar Photovoltaic Resources in California

Geothermal 2.0: Superior Value + Operational Flexibility = New Contracts

by Paul Thomsen, (GRC Member) Executive Director, Government and Regulatory Affairs, Ormat Technologies

The GRC Bulletin - Free to Download
In 2017, for the first time, the combined energy and capacity values of geothermal energy significantly exceeded the value of solar photovoltaic (PV) resources in California.

In the first quarter of 2017, geothermal’s wholesale energy value in southern California was $13.50/MWh greater than solar PV. At the same time, utility estimates of marginal solar PV capacity ratings for the 2018 Resource Adequacy (RA) compliance period were between nearly 0 percent and 20 percent, resulting in a capacity value difference of up to $18.50/MWh between geothermal and solar PV.

Today in California, geothermal has a combined energy and capacity value of $32/MWh higher than solar PV using very conservative assumptions. When you account for geothermal’s ancillary services and operational flexibility, combined values climb to more than $40/MWh higher than solar PV. These calculations demonstrate that geothermal can compete with solar PV on a net cost basis, even as PV costs continue to decline.

Wait…what? How can that be?

Indonesia: PGE Looking for Additional Investment to Complete 30 MW Karaha Geothermal Project

Pertamina Geothermal on its toes for PPA changes for 30 MW Karaha geothermal project (Asian Power)

Pertamina Geothermal Energy (PGE) is waiting for a final decision of amendments to a power purchase agreement with Perusahaan Listrik Negara (PLN) for its 30 MW Karaha geothermal project. Due to the massive investment required to make the project successful, Pertamina Geothermal is looking to increase the rate to $0.114/kWh.

According to the PGE website the project is located in WKP Karaha Cakrabuana in West Java Province, and is a continuation of development of the Karaha Bodas Project assigned by the Indonesian Government.

According to Pertamina Geothermal's director Khairul Rozaq, an USD 178m investment will be needed in order to produce the 30 MW from the project. These funds will be used for the upstream development of the project and to connect the plant to the 26 km-long transmission lines across 60 transmission towers.

New Zealand: Geothermal to Power Milk Processing Plant in Kawerau

Bay of Plenty Maori partner with Japan's Imanaka (News Release)

Kawerau industrial site (Courtesy Ngati Tuwharetoa Geothermal Assets)
A group of Maori organisations has partnered with Japanese food company Imanaka to develop a milk processing plant to make high-value niche products in Kawerau.

Kawerau Dairy is a collaboration between 11 Maori Bay of Plenty entities, which own two thirds of the venture, and Imanaka’s Cedenco Dairy unit, which owns the remaining third. They expect the first stage of the $32 million project to begin operations early next year.

The dairy venture is following the model of the Miraka milk company in Taupo which was set up by Maori interests with an overseas food group as a cornerstone shareholder, with power supplied from Maori geothermal assets and much of the milk supply sourced from local Maori farms.

The plant will be developed on land owned by Putauaki Trust with its principal energy supply sourced from the Ngati Tuwharetoa Geothermal Assets owned geothermal network.

New Zealand: Interview with New Geothermal Business Development Lead for Bay of Plenty Connections

Geothermal matchmaker steaming ahead with plans to create jobs in Bay of Plenty and beyond (NZ Herald)

Andy Blair describes her role as something of a geothermal matchmaker – it's about connecting those with resource to those who can benefit, creating jobs in the process.

After the official announcement of her appointment as the new geothermal business development lead for Bay of Plenty Connections at the end of last year, the Taupo woman is hitting the ground running.

Strange as it sounds, Blair says her goal isn't about preaching the virtues of geothermal – she knows others don't find it as exciting as she does – but instead helping businesses see where they can add value to their products by using the resource sustainably in systems where the resource is available.

It's when she talks about increased profits, environmental benefits and more jobs that she knows she'll get people on board.

Science & Technology: Combining Geothermal Energy Production and Thermal Enhanced Heavy Oil Recovery

Synergy potential for oil and geothermal energy exploitation (Applied Energy)

A new solution for harvesting energy simultaneously from two different sources of energy by combining geothermal energy production and thermal enhanced heavy oil recovery is introduced. 

Numerical simulations are employed to evaluate the feasibility of generating energy from geothermal resources, both for thermally enhanced oil recovery from a heavy oil reservoir and for direct heating purposes. 

The analyses suggest that the extra amount of oil produced by utilising the geothermal energy could make the geothermal business case independent and may be a viable option to reduce the overall project cost. Furthermore, the results display that the enhance oil productions are able to reduce the required subsidy for a single doublet geothermal project up to 50%.

Germany: Study Concludes Increased Renewable Energy Production will Take Shares Only from Coal

New German Government Adopts Coal Phase-Out in All But Name (The Energy Collective)

As a consequence, we estimate that increased renewable energy production will take shares only from coal. In our 65 percent RES scenario, coal produces 100 TWh of electricity in 2030; down from current levels at 250 TWh and down from 200 TWh in our 50 percent RES scenario.

Both the 50 percent and the 65 percent RES scenarios will be bad for coal. From a current level of 250 TWh per year, we expect coal power generation to drop to respectively 200 TWh and 100 TWh in the two scenarios.

In terms of GHG emissions, the effect will be significant. The German coal power plants let out around 250 Mt of CO2e in 2016. In our scenario, the remaining coal plants in 2030 are expected to emit 165 Mt.  This means that Germany will overshoot its abatement target by 85 Mt in 2030, reaching a 62 percent reduction instead of the 55 percent that is decided politically.
