Kenya: AUC Awards Grant to Fund Geothermal Exploration in Western Kenya

Homa Bay geothermal firm gets exploration millions (Business Daily Africa)


Kenya renewable energy firm Capital Power has secured $720,000 (about Sh72.6 million) from the African Union Commission (AUC) for a 140 megawatts (MW) geothermal prospect in Homa Bay County.

Director Tony Wanyama said the funds will be used to conduct a surface study and infrastructure upgrade programme at the Homa Hill.

The grant represents 80 per cent of the total cost of the surface exploration at $1.07 million (about Sh107.9 million).

Capital Power will conduct the studies starting this year, with the commissioning of the power plant expected by 2023.

Die Erdwärmenutzung durch oberflächennahe Bohrungen nimmt zu, aber die potenzialreiche Tiefengeothermie stagniert. Nun fordert die Branche Anschubhilfe vom Staat.

(From Google Translate) The use of geothermal energy through near-surface drilling is increasing, but the potential-rich deep geothermal energy is stagnating. Now the industry is calling for start-up aid from the state.


Some swear by the potential of an inexhaustible source of energy, while others warn against self-generated earthquakes, toxic gases and radioactivity. As controversial as the use of heat from deep wells is, their reality is modest: according to the German Geothermal Association, there are just 36 power plants in Germany that are known as deep geothermal energy. Its 35 megawatts (MW) electric power equals twelve modern wind turbines. The heat output of 315 MW looks a bit more impressive, it roughly corresponds to the power of three modern gas-fired power plants. Although there are plans for around 30 other plants, there are currently only two under construction. One in the Bavarian Holzkirchen, the other in Munich.

USA, Hawaii: Close-Up View of Conditions At Puna Geothermal Venture

Hawaiian Volcano Observatory Status Report (U.S. Geological Survey)

Wednesday, May 23, 2018, 10:46 PM HST (Thursday, May 24, 2018, 08:46 UTC)


Eruption of lava and ground cracking continues in the area of Leilani Estates and Lanipuna Gardens subdivision.

The middle portion of the fissure system continues to produce the most robust eruptive activity in the Lower East Rift Zone. The fountains from Fissure 22 feed a single lava channel that reaches the coast just north of MacKenzie State Park. The actual point of entry has continued shifting to the west. Fountains erupted from Fissures 5, 6, 13, and 19 continued to feed a lava flow advancing to the south along the west side of Fissure 22 flows that reached the ocean late this afternoon.There are now two ocean entry points that produce occasional small explosions.

Volcanic gas emissions remain very high from the fissure eruptions.

USA, Hawaii: Lava Wall is Blocking Molten Rock from Flowing North Toward Puna Geothermal Venture

Lava wall protecting geothermal plant (KITV Honolulu)

(Video 1:39 Minutes)

Officials say lava spatter from Hawaii's erupting volcano is creating a wall that's helping protect a nearby geothermal plant.
  
U.S. Geological Survey scientist Wendy Stovall said Wednesday that lava erupting from a vent closest to Puna Geothermal Venture is shooting higher than lava coming out of other vents. She says it's also producing the highest lava wall, which is blocking molten rock from flowing north toward the plant.
  
Residents have been concerned about hazards if lava flowed over the plant's facilities or if the molten rock heated chemicals at the plant. Lava from the eruption on the Big Island is primarily flowing south toward the ocean.
  
Officials shut down Puna Geothermal shortly after Kilauea began erupting on May 3. On Tuesday, officials finished plugging wells that bring up hot liquid and steam that feed a turbine generator.

Netherlands: Opportunities for "Ultra Deep Geothermal"

Can Ultra-deep Geothermal Contribute to a Sustainable Energy System? (Elektor)

(Courtesy CIA.gov)
The last five years, geothermal energy has seen a slow but steady rise. District heating in Germany, France and the Netherlands is a success. Due to financial and regulatory constraints growth of Ultra Deep Geothermal (UDG) energy slackens, though. Can UDG serve as a renewable energy source in the Netherlands, now that it is phasing out Groninger gas?

Ultra deep geothermal energy (UDG) is ..... a chance for Dutch industry as well as a headache. Some forty percent of all energy demand in the Netherlands is heat; housing and process industry take an equal share. Up until now, UDG is used at two to three kilometres depth for sixteen greenhouses in Holland (Westland and Haarlemmermeer) but there are opportunities for other industries (like paper and dairy) as well. Moreover, the Dutch government recently announced that natural gas from its Groningen field has to be phased-out before 2023 (due to recent earthquakes in the Northern part of the country).

Science & Technology: Algorithms Pick Out Hidden Signals that Could Boost Geothermal Energy Production

Machine learning reveals cyclic changes in seismic source spectra in Geysers geothermal field (Science Advances)


The earthquake rupture process comprises complex interactions of stress, fracture, and frictional properties. New machine learning methods demonstrate great potential to reveal patterns in time-dependent spectral properties of seismic signals and enable identification of changes in faulting processes. 

Clustering of 46,000 earthquakes of 0.3 < ML < 1.5 from the Geysers geothermal field (CA) yields groupings that have no reservoir-scale spatial patterns but clear temporal patterns. Events with similar spectral properties repeat on annual cycles within each cluster and track changes in the water injection rates into the Geysers reservoir, indicating that changes in acoustic properties and faulting processes accompany changes in thermomechanical state. 

The methods open new means to identify and characterize subtle changes in seismic source properties, with applications to tectonic and geothermal seismicity.

Lava from Kilauea volcano has destroyed the former Hawaii Geothermal Project site adjacent to Puna Geothermal Venture, according to Hawaii County Civil Defense Director Talmadge Magno.

In his noon update for radio today, Magno said, “There is no immediate threat to any of the wells at PGV.”


From the Hawaiian Electric Company website: For eight years, Hawaii Electric Light Company operated the Hawaii Geothermal Energy Project-Wellsite A, a 3-megawatt power plant.

In the 1980s, the “Hawaii Deep Water Cable ” study was funded by the U.S. Department of Energy and the State of Hawaii Department of Business, Economic Development and Tourism. Hawaiian Electric Company was the prime contractor for the study with the actual research work done by a number of subcontractors.

Completed in 1990, the multi-year research project concluded that transmitting geothermal electricity from Hawaii Island to Oahu was technically feasible. However, the State did not pursue the project due to high costs and possible environmental impacts related to the project at a time when oil prices remained relatively low.

United Kingdom: Funding Approved for Eden Deep Geothermal Energy Project

Funding Approved For Geothermal Power Source At Eden Project (Insider Media)

Funding for a project which could power Cornwall's Eden Project with renewable energy has been given approval by Cornwall's Council.

The project, proposed by EGS Energy in partnership with Eden in Bodelva near St Austell, involves drilling a well to gain access to the hot rocks below, creating enough heat and electricity to potentially power the Eden Project and surrounding homes.

Cabinet portfolio holder for planning and economy, Bob Egerton said: "We know that granite in some areas of Cornwall has the highest heat flow in the UK – and the natural geothermal springs are rich in Lithium deposits.

"If we can find a way to exploit geothermal power successfully, these hot rocks have the potential to provide Cornwall with a rich source of strategic minerals and renewable energy, as well as significant benefits to the local economy from jobs, research and investment.

"By supporting one-off exploration projects like Eden and United Downs, This exploration for geothermal power at the Eden Project is a first step towards testing the technology we need to help us to exploit geothermal power more widely across Cornwall."

A geothermal well field next to a volcanic rift that is fountaining lava was declared “essentially safe” Tuesday after measures were taken to prevent uncontrolled releases of underground fluids and gases.

Crews used water to quench two Puna Geothermal Venture wells and inserted a chemical plug into a third well on the property.

Tom Travis, administrator of the Hawaii Emergency Management Agency, said the wells are isolated and are each sealed off with two large valves on top “so the status is stable, predictable and understandable, and there’s no reason as a result of any of the status of wells to feel any undue concern.”

Opinion: Uncertainty Makes Geothermal Less Attractive to Investors and Utilities

Opinion: Lack of long-term U.S. energy plan impedes transformative technology (The Brookings Institution)

Lance Collins, J. Silbert Dean of Engineering - Cornell University

In the case of geothermal, there are no national guidelines indicating how much it should be contributing to total energy production. Support for geothermal projects in the form of loan guarantees, lending support, or cooperative agreements has been inconsistent since the 1970s and a tax credit for geothermal developers expired in 2016 – the same year a new energy bill stalled in Congress that may have boosted funds directed at geothermal projects. This uncertainty makes geothermal less attractive to investors and utilities.

In the more than 60 years we’ve recognized energy as an important societal problem, we’ve failed to come up with the means and determination to change our reliance on fossil fuels. Researchers in universities and labs across the country will continue to innovate and find new ways to make energy more efficient, cheap, resilient to natural disasters, and less damaging to the environment. It is essential that we partner with government and policymakers to create a pipeline for these innovations to reach the market, so that we can ensure a sustainable energy future.

USA, Hawaii: Lava Inches Closer to Puna Geothermal Venture but Main Flow Stays Away

Lava creeps onto geothermal plant site on Hawaii's Big Island (Reuters)

A lava flow encroaching onto the shuttered Puna Geothermal Venture power plant destroyed a warehouse on the property Monday evening, but the top executive in Hawaii for PGV said the concerns about lava inundation at the plant have been overblown.

Star-Advertiser photo by Cindy Ellen Russell.  
Molten lava from the erupting Kilauea Volcano on Hawaii’s Big Island crept onto a geothermal power plant site on Monday, as workers rushed to shut down the facility to prevent the uncontrollable release of toxic gases.

Crews worked into the night to cap the 11th and final well at the Puna Geothermal Venture (PGV) plant, which provides about 25 percent of the Big Island’s power, as lava from an active fissure flowed 200 to 300 yards from the nearest well pad, county and federal officials said.

The plant has been closed since shortly after lava began erupting on May 3 through newly opened fissures in the ground running through neighborhoods and roads on the far eastern flank of Kilauea.

Within a week, some 60,000 gallons (227,124 liters) of the highly flammable chemical pentane, which was stored at the plant, were moved from harm’s way. The state said last week it was pumping cold water into the wells and would cap them with iron plugs.

USA, New York: Cornell University Presents Geothermal District Heating Scheme

Cornell experts present ambitious geothermal proposal to community (ithaca.com)



Seeking a carbon neutral solution to heat its campus, Cornell – a university with a storied history of digging giant holes – presented their proposal for what, by volume, is likely to be the largest hole dug in the university’s history; one, they say, could lay the groundwork for a revolution in district heating in the Northeastern United States.

At a session Thursday evening attended by dozens of members of the community and faculty, a group of Cornell researchers presented a preliminary outline of their proposal for a massive geothermal heating system they hope to build beneath Cornell’s campus. The ambitious project, first proposed as part of the campus’ climate action plan drafted in 2009, aims to heat Cornell’s campus by digging a hole nearly three miles down, encasing it in concrete and pumping a solution of water and anti-corrosive deep into the earth, where it will be heated and recirculated 15,000 feet above through a system of pipes throughout the campus.

USA: NREL Streamlining Collection and Sharing of Geothermal Data Sets

Access to Data Accelerates Innovation and Adoption of Geothermal Technologies (NREL)

The future of research and development in the geothermal sector is being driven by data-informed decisions and research built upon the quantifiable outcomes of previous endeavors.  The U.S. Department of Energy (DOE) has adopted a strategy of measuring success “not when a project is completed, or an experiment concluded, but when scientific and technical information is disseminated.” The timely dissemination of critical information is what allows future research projects to build upon previous lessons learned, reduce duplication of efforts, and combine findings into new innovative research projects.

Over the past few years, National Renewable Energy Laboratory (NREL)’s geothermal team has developed several tools and platforms to streamline the collection and sharing of geothermal data sets, enabling new breakthroughs in geothermal research and development.

Europe: What Stakeholders in Near-surface Geothermal Resource Project Need to Develop their Projects

Report of the relevant needs of Stakeholders in the field of Near-surface Geothermal Resources (GRETA)

12 partners from 6 different countries has met into the GRETA project with the aim demonstrate the potential of Near-surface Geothermal Resources (NSGE) in the Alpine Space and to share its knowledge to foster the integration of this technology into future energy plans in the area at different administrative levels. This approach will help to reduce total CO2-emissions in environmentally sensitive regions using renewable energy sources which are very widely available, thus establishing transnationally integrated low carbon policy instruments.

On the basis of the results presented from Focus Groups in the Pilot Areas of Germany, Italy and Slovenia, the understanding of differences and similarities of barriers and needs regarding the expansion of the geothermal system in the given countries have identified the initial installation cost as a common barrier.

The data analysed in this comparison reveal each of these countries having different needs and barriers in regulations, financial, technical, research, organisation and administration, geological maps and opportunities areas. The strong association between these barriers and local and national administration dynamics suggests own directions for policy makers and the geothermal private sector within these sampled countries to be sought for the expansion of own national geothermal sector.

Sweden: Climeon Reports Rapid Progress in Geothermal Heat Power Projects

Climeon Investor News - Interim report for the period 1 January - 31 March 2018 (News Release)


Important events, January - March included:

  • In January 2018 Climeon owners Gullspång Invest AB, LMK Forward AB and Blue AB decided to establish the financing company Baseload Capital Sweden AB (Baseload Capital) to accelerate global geothermal heat power projects. Climeon will participate through a minority stake of 19.9 percent 
  • A business agreement worth over EUR 5 million was signed in February 2018 with the German energy provider Geoenergie Kirchweidach, resulting from the Letter of Intent signed in the fourth quarter 2017 

Important post-closing events include:

  • During April, a new business agreement was signed with Borealis GeoPower, Canada, worth around EUR 1 million. Climeon has thus won the world’s first order of geothermal power plant in Canada
  • A representative office opened in Japan to investigate and evaluate Climeon’s potential in the local market 

Thomas Öström CEO: We see proof after proof that it is attractive for customers and financial backers to invest in geothermal heat power. The plants produce electricity around the clock, all year long, and electricity producers can sign long-term Power-Purchase Agreements (PPA) with a fixed price (i.e. during 15 years) for the electricity supplied to the grid. A product that makes electricity from hot water thus makes money out of hot water with great predictability for a long time to come. Cash flow and investments can thereby be calculated, which also makes it easier for customers to obtain financing. 

The existence of Baseload Capital is a clear advantage since customers frequently need to finance their investments externally. For understandable reasons, banks lack experience in financing our type of heat power, which means that the processes are slower when using a bank. Baseload Capital focuses entirely on sustainable baseload power, and can offer our customers pre-approved loans with favorable conditions. Baseload Capital provided financing for both Icelandic Varmaorka and U.S. Wendel, thereby freeing Climeon from its previous financing commitments to these customers. 

Finance: “A faster route to power production, which improves the business case, is to use ‘wellhead generators’.”

Decreasing the equity requirements with wellhead power plants (Green Energy Geothermal)


At the Iceland Geothermal Conference, London-based Green Energy Geothermal (GEG) gave a presentation as part of a session on competitiveness and innovation.

Featuring three technology providers, including GEG, a proposed GeoMagma power plant and a presentation the competitiveness of the geothermal sector, the session focused on how different approaches could help in more geothermal development.

In its presentation, GEG focused on a recent financial model done by a third party, looking at the financial impact of staging a larger-scale geothermal development 110 MW project. The case study looked at two scenarios, the traditional approach with two 55 MW units and another approach with eleven 10 MW units by GEG.
