CRM-Geothermal Kick-off meeting, Potsdam, July 2022

/in /by

CRM-geothermal recently started and LPRC is part of it. The kick-off meeting was held in July – in hybrid mode. On the 13th and 14th the project partners met in Potsdam, Germany, as well as online, to start the high-level discussions involved in CRM-geothermal Work Packages and their respective technological aspects. CRM-geothermal will open up a potentially huge untapped resource and deploy solutions to help Europe fulfil the strategic objectives of the EU Green Deal and the Agenda for Sustainable Development by combining the extraction of heat and minerals from geothermal wells.

In this context, LPRC (portrayed by Marcio Tameirão) was present at the event to talk about what is planned to be performed in the next four years, as well as the expected results and collaboration from the consortium partners. La Palma Research Centre is the leader of two tasks:

Task 4.4 – Market Deployment. This task is from Work Package 4 – Deployment of the combined extraction of CRM and energy from geothermal fluids, led by INTRAW. The objective is to develop a roadmap for the potential upscaling and commercialization of the technology involved in the extraction of CRM (Critical Raw Materials) from the brine in geothermal wells.

Task 6.6 – Clustering. This task is from Work Package 6 – Dissemination, communication and exploitation, led by EFG. The objective is to foster connections with communities working on similar topics and challenges; create long-term research collaborations and scientific investigations; increase project visibility; and contribute to the exploitation potential of results.

The event was a great opportunity for the consortium partners to meet in person and get to know each other, which naturally improves the conditions to collaborate in the upcoming years.

Environmental evaluation of a Geothermal Power Plant in the Southern German Molasse Basin by a Life Cycle Analysis

/in /by

On the 26th March 2021, ENERCHANGE and ThinkGeoEnergy hosted a new episode of their recurring Focus on Geothermal – Energy for the Weekend event this time focused on Life Cycle Assessment of Geothermal Energy to raise public acceptance based on a German Case Study.

Geothermal Energy and social acceptance

The webinar highlighted the competitive disadvantage of geothermal energy compared to other energy sources due to public opinion. Despite of its green potential and output advantages (baseload capacity, long lifetime of operation and wide accessibility), geothermal is often perceived a harmful energy source by general public.

According to the present case study and similar past conclusion of experts, the roots of poor social acceptance performances of geothermal energy lie in poor communication of geothermal green capacities compared to other energy sources both fossil and green. The German team hosting the event suggested that a clear demonstration of the green output of geothermal energy could outweigh negative initial views on the technology. In addition, the team believes that a strict environmental monitoring of geothermal power plants is necessary to showcase transparency, accountability and good faith of geothermal developers. To that end, the team proposed that geothermal projects shall establish a thorough Life Cycle Assessment (LCA) of their operations from exploration to decommission to monitor CO2 emissions and take measures if levels are abnormally high.

Life Cycle Assessment for geothermal projects

A Life cycle assessment is a technique to assess environmental impacts associated with all the stages of a product’s life, spanning from raw material extraction through materials processing, manufacture, distribution, and use.

Possible considerations of a Life Cycle Assessment for Geothermal plants.

Based on this new operational framework for a Life Cycle Assessment in geothermal, 3 steps have to be taken into account when assessing geothermal power plants:

  • Drilling geothermal wells require energy (often electricity) whose origin (fossil v. renewable) has to be taken into account. Furthermore, building a plant requires, raw materials, transport and auxiliary energy. All of which have a carbon footprint. The total energy demand for input will be accounted for in the calculation of the environmental impact of a project.
  • The same principle applies for the output of a station. Whilst the electricity produced by a geothermal power plant might be 100% clean, it bears the limitations of transport of raw materials for construction and the building of the plant itself.
  • Finally, it is necessary to ensure that refrigerant used in geothermal turbines shall not leak which would have a detrimental impact on the environment. One way to ensure transparency and maintenance of high safety standards throughout the lifetime of a geothermal plant is to enforce environmental monitoring. Said monitoring shall be available to the public to showcase the good performance of geothermal energy which would then improve social acceptance of the technology once the public sees for itself that geothermal has great versatility coupled with high environmental standards.

LPRC participates at the GEOENVI-CROWDTHERMAL joint webinar – part 2

/in , /by

The recommendations coming from GEOENVI (see part 1) directly echoe the CROWDTHERMAL project’s vision for social acceptance on geothermal projects. CROWDTHERMAL identified 4 factors of public acceptance:

  1. Self-efficacy: Energy transition means the change of infrastructures and daily life environments. It is important to experience one’s own impact and influence within this transformation process.
  2. Identity: The more people can identify emotionnally with a measure, the greater their willingness to accept it. This means that infrastructure measures must also be recognised emotionally as elements of one’s own living environment. This is more likely to happen with more local stakeholders involed (regulators, SME and local communities).
  3. Orientation and insight: If people understand the necessity of a political decision and support the goals and means envisaged by this decision, they are more likely to accept it. Therefore, transparent information is needed about what they will face. Crucial elements are transparency about pros and cons and potential alternatives.
  4. Positive risk-benefit balance: Acceptance is more likely the more the planned consequences of a decision benefits oneself or related groups. This includes the perception of low or at least acceptables risks. In this context, the risk assessments of experts and those of laypersons are often not congruents.

Finally, with regard to financing of geothermal projects, CROWDTHERMAL confirmed that community funding can play an important role to initiate and support geothermal projects by raising additional funds. Especially in the early project development phases, alternative finance methods can enable more geothermal projects to be brought to life. Community funding can also achieve public engagement and increase acceptance. In the light of the massive investments needed, especially for deep geothermal power projects, community funding is yet not considered to be functional entirely on its own, but rather in combination with other (conventional) forms of finance.

Community funding can play an important role to initiate and support geothermal projects.

The most suitable alternative finance method very much depends on the individual project characteristics and context. At the early project development stages, especially crowdfunding (shares/equity or reward-based) can be attractive options to achieve community co-ownership and to enhance project support. The high resource-related risk in the early phases leads to high return expectation of investors. Community funding is generally less risky in the construction and operation phases, but the potential returns at these stages are also less attractive.

Understanding and developing a project in a holistic way, taking into consideration technical, financial, and social dimensions as well as their interdependency is an important risk mitigation measure for project developers. It reduces the risk of interface problems and increases the chances for a Social License to Operate as well as for technical and economic success.

LPRC participates at the GEOENVI-CROWDTHERMAL joint webinar – part 1

/in , /by

On Tuesday 16 March, GEOENVI and the CROWDTHERMAL project, where LPRC leads one work package, hosted a joint online event titled: “Targeting acceptability and co-ownership for deep geothermal projects”. In this event, an expert panel discussed recommendations and ways forward for public engagement for deep geothermal, based on good practices on crowdfunding from the CROWDTHERMAL project and gave some academic perspectives on the subject.

Mission statement of both projects:

The objective of the GEOENVI project is to answer environmental concerns in terms of both impacts and risks, by first setting an adapted methodology for assessing environment impacts to the project developers, and by assessing the environmental impacts and risks of geothermal projects operational or in development in Europe.

The webinar (part 1):

Both EU projects tackle the question of public engagement with different hypothesis, so this webinar was an opportunity to gain a better overall understanding of public engagement based on two different scopes and methodologies.

The first part of the webinar was focused on the research output of the GEOENVI project. GEOENVI argues that further development of geothermal projects will boil down to creating an energy community and better communication on the side of developers. The combination of these two aspects is believed to have the potential to raise social acceptance of geothermal projects.

Building an energy community is the action of involving local stakeholders (regulators, local industries, SMEs and individual citizens) in the production of sustainable heat and/or electricity. The aim is to ensure that energy production can provide opportunities to local businesses (see similar conclusion from the Trends in geothermal webinar) as well as energy for local households. The figure below showcases some of the inititation that may be undertaken by project developpers and regulatory authorities to insert energy project in a community to the benefits of a variety of economic activities.

1Initiatives to promote the sustainable development of geothermal areas.

With regards to dissemination and communcation of project activities, GEOENVI discovered that there is a gap between how project developpers think they communicate and how the public feels it is informed. On the following figure,  it is appararent that the public generally feels poorly informed. This misunderstanding in communication draws a wedge between a project and its surrounding community. In Alsace, this wedge resulted in tension between local communities and geothermal development in spite of the geothermal potential of the area and the positive economical impact of competititive green energy on its surrounding market. The problematic is particularly interresting when we consider that misinformation leading to mlistrust of a technology is also visible in other sector (wind turbines, electric cars and more recently vaccines).

Participation in public inquiries held in Alsace 2015/2016.

Based on these two problematics, GEOENVI will provide policy recommendation for the European Union in hope that it could turn the tie of geothermal development in the continent, thus meeting climate goals whilst ensuring social gains at local level.

GEOENVI calls for European standards on information sharing by setting up minimum qualitative requirements for information sharing on energy projects. This will not only ensure better trust into new green technologies but also enables project developpers to draw conclusions from other projects that have similar minimal communication requirements:

  • Choose and collect the relevant information enabling project developpers and researchers alike to confidentially collect environmental concerns and posititve impact to compare any project with other Renewable Energy Sources (RES);
  • Adapt the communication target: distinguish ‘public’ from ‘experts’ in the communication strategy so that anyone can understand the purpose and methodlogy of an energy project in his/her/their own words;
  • Improve data accessibility and awareness of accessible information: FAIR data principle , independent appeal commintee for confidentiality issues;
  • Share reliable information: All project developpers shall ensure a pro-active data sharing strategy to inform the public in the name, of transparency and trust building.

Trends in geothermal, 16th February 2021 part 2: technology

/in /by

The first part of the Baseload Trend’s geothermal webinar focused on hurdles linked to financing in new technologies and emerging trends. With regards to geothermal, the trends for the future unfold in three aspects: shallow geothermal, deep geothermal and thermal storage.

Shallow geothermal has received more and more attention recently due to the decentralisation of the energy market. Local energy demand and concepts such as energy communities are trending due to the unlikeliness of large scale and centralized power plants to meet heat and electricity requirements of all communities throughout a region, especially those most remote. In the past, geothermal would not have been able to meet these spikes in demand. Fortunately, advances in technologies, heat exchangers and miniaturization enable smaller plants and heat pumps to provide affordable and competitive energy to smaller markets. In addition, micro-grids for small markets are easier and quicker to develop than extensive grid system joining large power plants to remote and smaller energy demand. This local approach will ensure that small communities are not behind the renewable energy curve – especially important to make sure that countries will meet climate target, by ensuring a comprehensive renewable energy grid whilst promoting a fair transition where each individual has access to local affordable clean energy without bearing the costs of long and complex grid to dispatch energy home. Finally, local energy disables the need to depend on foreign oil, gas and electricity thus improving national energy security and making prices less volatile.

Main themes and subtopics of the overall CHPM concept: exploration, development, operation, market. CHPM2030 developed a concept for a new geothermal-related technology.

Shallow geothermal is only one face of the “geothermal trend coin”. Deep geothermal has a complementary role to shallow in any national grid. Whilst, shallow geothermal often implies smaller power plants (or heat pumps) for less energy demanding markets, deep geothermal often implies higher temperatures and thus higher power outputs for more energy demanding markets. Two main trends are foreseen for deep geothermal in a near future: first, scalability of operations thanks to lessons learned from the oil and gas industry (it would be possible to take lessons learned from these technologies to apply them to new geothermal fields); second, economies of scale could greatly benefit from geothermal deep drilling in the future since more drilling would reduce the marginal cost of each plant by incorporating the lessons learned from past experiences. Finally, experts believe that the future of deep geothermal plants is ultradeep rigs (around 10km deep). Such high depth is on the horizon thanks to drilling techniques developed by the oil industry. Almost any point of the globe reaches very high temperatures (around 200°C) at such depths meaning that any place could, theoretically, be producing large quantities of clean energy for decades.

Energy production is not the only benefit of geothermal. This renewable source has the added value to be able to be suited for thermal energy storage. Thermal energy storage (TES) is a technology that stocks thermal energy by heating or cooling a storage medium so that the stored energy can be used at a later time for heating and cooling applications and power generation. Wind and solar may be better at delivering the cheapest net kW/h, but storage is cheaper for geothermal. This is important because different perks of different energy sources emulate the best in each or in a comprehensive energy mix. Geothermal energy and thermal storage will be able to form the baseload power of an energy mix whilst fluctuating power sources such as wind and solar will supply peaks in demand. In the end, there is no silver bullet to fight climate change but, rather, a comprehensive system of clean technologies enabling a secure and fair carbon transition.

Trends in geothermal, 16th February 2021 part 1: investment

/in /by

On the 16 February 2021, Baseload Capital (an investing firm) hosted its webinar on upcoming trends in the geothermal sector. Its philosophy is to act as a catalyst for green baseload electricity by funding renewable energy projects throughout the world. Currently, the company has subsidiaries in Iceland, Japan and Taiwan, which work with local communities and power companies to permit, build and commission heat power plants.

The first half of this two-part article will focus on investment in geothermal and what the future is holding for finance in energy. Geothermal represents an interesting case study for financing carbon neutrality. However, with only 2% of the global energy market, geothermal is lacking behind other energies despite its upsides: available 24/7, 365 days a year independently of weather, outside temperature or time of the day. In addition, it can serve as a baseload power (minimum amount of electric power needed to be supplied to the electrical grid at any given time) for any renewable energy mix. Day to day trends of power usage need to be met by power plants, however it is not optimal for power plants to produce the maximum needed power at all times. Geothermal power plants have average availabilities of 90% or higher, compared to about 75% for coal plants. Geothermal power is homegrown, reducing our dependence on foreign oil. So, if geothermal is so convenient why is it lagging behind other energy sources?

Geothermal suffers from several misconceptions that are often afflicting new investment opportunities. First, the Kodak core business model is a good example of neglecting new emerging trends for already established goods and services. We all know what happened to Kodak and printed photos. But the question is: would we really have acted differently if we had been in their shoes? Many examples since then seem to indicate that we tend to misjudge the potential of emerging technologies.

Second, connecting dots. Some technologies are on the shelf because their fullest potential can only be met by combining them with other technologies. When identifying 2 or more trends with inherent potential, they can create a whole new concept sparking new business opportunities in a market. Going back to geothermal, this concept is incredibly relevant. On one hand, it is a fact that energy demand is rising. On the other, the energy industry realizes that power production (heat and electricity) is too centralised and thus could face problems to reach the widespread growing demand. In parallel, it has been apparent that geothermal energy opened new opportunities for building medium and low-grade power plants for heat able to meet local demand that previously did not make sense financially. An example of this is Iceland: local communities have a growing demand for clean energy yet most of electricity production is generated around the capital Reykjavik. These conditions are perfect for local distributed geothermal power to supply local communities with affordable, clean energy based on low temperature heat.

Third, discovering new trends. Trends create momentum in a market when many people are affected by it. A large, invested community increases the likelihood of a successful emerging trend. In essence, it boils that to marketing: capturing the imagination of a targeted community with business opportunities or services that can benefit them or society as a whole. For instance, geothermal tends to be the fields of experts, scientists and selected groups of individuals. Whilst, this group produces a lot of positive ideas, disruptive technologies and discussions, outcomes tend to circulate into the same circle, depriving the overall field of a greater reach. Hence, these trends are de facto on a shelf waiting to be discovered by the wide public. Incidentally, being on the shelf does not allow one trend to find an application that would have a positive snowball effect on society.

Therefore, nowadays it is likely that new trends and investments in geothermal will focus on meeting the energy demands of local communities whilst being integrated to the economical ecosystem. A geothermal power plant could provide district heating for neighbouring homes, heat for local organic greenhouses, hot water for the local swimming pool or spa and countless other solutions benefiting communities. This comprehensive approach does not only benefit investors but has lasting positive impacts on future generations. Said impact could also be the added value needed to increase the social acceptance of geothermal. By integrating communities, businesses and private citizens in their local energy ecosystem a lasting relationship between energy producers and customers can be achieved.

LPRC @ Webinar – Recent installations, implications for the future of geothermal in Turkey

/in /by

On Friday 29, Gauthier Quinonez (LPRC) attended the latest IGN online webinar on geothermal energy organized by Enerchange (PR and Event Agency focusing on renewable energy) and Think GeoEnergy (leading newspaper on geothermal). The event focused on the particular case of Turkish geothermal, its characteristics and future.

Top that occasion, the board invited Gad Shoshan (chairman at the board at the Israel-Turkey business council and chamber of commerce and managing director at Ormat Inc.) to discuss the current state of play. Ormat is a global renewable energy provider based in Reno (Nevada). The company has the particularity to be verse in multiple renewable energy sources (geothermal and recovered energy) as well as energy storage. In addition, with regards to geothermal, they managed to vertically integrate all phases of geothermal (Development, exploration, drilling, engineering, manufacturing, construction, operation and stakeholder management).

First of all, even though Turkey has become famous of over the past decade for its rapid and sustained development of geothermal, the country is still highly reliant on fossil fuels for domestic electricity production (Fig. 1). However, 3 caveats shall be made on this current status. First, all but one active Turkish power plants opened after 2006, highlighting the impressive capacity to adapt to new resources. Second, Turkish geothermal potential hasn’t been reached yet, indicating a possible growing share of geothermal electricity in the Turkish market for the future. Third, most fossil fuel consumption is linked to import from the East, highlighting a threat in local energy security and Turkish authorities made no secret about the need for a change in this matter.

Figure 1: Turkey’s electricity generation per resource

As per January 2021, geothermal energy’s output in Turkey is 1.6 GW produced by 77 power plants (with a mix of Organic Rankine Cycle[1] and flash). Although 77 power plants may seem like a high number for the country it does not meet the high demand of 84 million Turkish and does not cover the huge local geothermal potential. Figure 2 shows current knowledge of Turkish geothermal potential (red areas) and locations of operational plants (ref triangles). Based on the map, it can be concluded that Central and Eastern Anatolia are underexploited vis-à-vis their potential. In addition, there is still a lack of exploration and research to determine the true potential of the Mediterranean and Black Sea regions.

Figure 2: Turkish geothermal potential

All and all, the Turkish geothermal case study proves that the technology can be developed quickly and efficiently (76 power plants in under 15 years) despite a somewhat shaken economy (current devaluation of YLT and high unemployment). Lessons can be learned globally from the Turkish case.

[1] Organic Rankine Cycle is a technology that convert low-temperature heat sources into a mechanical energy, and it can be used to produce electrical energy in a closed system.

LPRC participates at “Geo-Energy Operations: Opportunities and Challenges” webinar

/in /by

On the 16 December, The Welding Institute hosted its webinar titled “Geo-Energy Operations: Opportunities and Challenges Confirmation”. TWI is a global leader in technology engineering providing research and consultancy to its members.

The session was focused on one research question: “Why is geothermal still the hidden champion of energy?”. Geothermal has a very high potential on Earth. As a matter of fact, 99.6% of the planet is above 500 degrees Celsius, which begs the questions, why relying so much on oil and gas?

In addition, geothermal is a baseload power. Baseload power refers to the minimum amount of electric power needed to be supplied to the electrical grid at any given time. Day to day trends of power usage need to be met by power plants, however it is not optimal for power plants to produce the maximum needed power at all times. Earth’s warmth is not dependent on the time of the day, season or weather, it stays warm and will continue to stay warm for billions of years.

On top of potential and availability, recent developments in technology and general economies of scale have pushed geothermal competitiveness to the forefront of the energy race. Figure 1 showcases the unsubsidized cost of alternative and conventional energy sources. Two conclusions can be drawn from this graph; first, being unsubsidized levelized costs; second, although more competitive, biomass and wind have their drawbacks.

Conventional and alternative energy costs.

The ambitious vision developed for geothermal is challenged by a slow growth and implementation of geothermal worldwide. The International Geothermal Association  highlights that geothermal Growth rate of geothermal is only 3%, which is not enough to meet UNDP (United Nation Program for Development) Objective 7 – focusing on clean and affordable energy for all. To reach this global objective, the annual growth rate of geothermal (electricity, heating and cooling) needs to be 9 to 12%. Market studies suggest that the main hurdles to overcome include initial investment and public perception. Realistically, these two notions boil down to one simple concept: trust.

Investment relates to a trust into geothermal to yield positive return on investment while maximising the cost management of operations. Academic studies suggest that trust in geothermal can be raised via sharing best practices and technical development leading to cost reduction. This combination of actions enabled a noticeable growth in solar and wind power generation over the past decade.

Finally, trust is also capital when discussing public perception of geothermal energy. Best practices across the globe demonstrate that successful geothermal projects are synonymous with open and trustworthy communication with local communities. In the words of Marit Brommer, Executive Director at IGA: “both geothermal experts and non-experts shall discuss with the public about geothermal. The public shall always be engaged openly and with non-technical jargon to ensure clear communication and more importantly: dialogue. These open discussions will not only benefit the geothermal world but society as a whole.”.

Will 2021 bring new opportunities for geothermal energy?

Shallow Geothermal Days 2020: Day 3: Minutes

/in /by

On the 11th December 2020 took place the third and final day of the Shallow Geothermal Days 2020. On  opportunity the focus shifted from the perks of shallow geothermal and the European potential to the incorporation of geothermal energy in the future of European Carbon neutrality.

It is no secret that the European Union is massively investing in renewable energy sources and energy storage to decarbonize its economy. The session once again proved the necessity of geothermal energy in the upcoming carbon neutral market. Not only geothermal has a huge green and economically viable potential but it also shows potential in disruptive technologies such as combined renewables sources and thermal storage. Combined renewables sources consist of two or more renewable energy sources used together to provide increased system efficiency as well as greater balance in energy supply. For example, geothermal could provide baseload energy whilst alternating energy sources could provide additional power at pick demand time.

Main themes and subtopics of the overall CHPM concept: exploration, development, operation, market. CHPM 2030 was one of the innovative projects funded under the Horizon 2020 programme where LPRC participated.

It is now important for the European Commission and its institutions to act on climate and to act quickly. To that end, the Innovation Fund has been launched to fund a number of projects to help with changing the energy panaroma. A total of 58 out of 322 proposals submitted (18%) on the 2nd December for Large-Scale projects under the Innovation Fund were geothermal energy-related (mostly heating and cooling and thermal storage). Whilst this high number of geothermal projects does not reflect the final outcome of the bid, it however shows a growing interest in the technology on the European scene.

Will Europe be able to meet its energy-related challenges for the upcoming years?
