ROBOMINERS project Review Meeting

On 29 January 2021, the ROBOMINERS project had its first review meeting with the EC. Our team was present as leaders of Work Package 8 to assess and discuss the main outcomes.

The review meeting, which lasted the whole Friday, was built around presentations of the work done since the beginning of the project until now. Each Work Package leader presented the results and engaged in fruitful discussions with the EC to clarify doubts and employ recommendations for improvement. As a Work Package leader, LPRC (Luís Lopes) made the presentation on Work Package 8 – Active roadmapping and clusters. Luís gave an overview of the clustering activities developed and implemented up to now, as well as the Focus Groups and Horizon Scanning exercises with experts. The presentation of the work was well received and no major doubts or recommendations were put forward.

The efforts of clustering and roadmapping will continue in the next months with a series of engaging activities!

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

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.

Register for the ROBOMINERS project webinar!

On 18 February 2021 the ROBOMINERS project is organising a webinar on “Small and very-small scale robotic mining: deposit types and opportunities for Europe”.

The aim of this virtual event is to:

  • Provide an overview of abandoned mines in Europe and their potential
  • Discuss the challenges of reopening an old mine
  • Outline the different steps from the discovery of a deposit until the opening of a mine
  • Present expected contributions of the ROBOMINERS technology to resume operations in abandoned mines where the application of conventional technologies is not relevant

The webinar is scheduled for 14:00-16:15 CET and speakers will be announced in the coming days.

Recap of the “Focus on Geothermal – Energy for the Weekend” Webinar

How can deep geothermal be green whilst releasing CO2 emissions into the atmosphere?

The figure below seems to indicate that deep geothermal energy is not as green as it could be assumed, in some instances reaching levels of emissions comparable to fossil fuels energy sources (gas, coal and oil). However, this graph is a simplification of what is really at stakes. First of all, geothermal emissions here are presented as life-long emission meaning resulting from exploration, drilling, building the plant, manufacturing of all the parts, operation and decommission. All but stages but operation are CO2 emissions that currently cannot be avoided because of the reliance on fossil-fuel for manufacturing any part and the value chain in general.

With regards to CO2 emissions during geothermal operation one might wonder why an energy source that does not burn fossil fuel nor carbon content still produces GHG emissions. And this is due to the CO2 content into the water reservoir from which heat is extracted. Think about a bottle of sparkling water when the lid is on, there is no bubble rising to the surface of the water and therefore no gas can expand, in short: CO2 is dissolute in the water, the system is sealed. Once you open the bottle, you witness this characteristic “pop” (due to expanding gases) followed by a rush of CO2 bubbles to the surface that then make their way to the atmosphere: the system is open.

Deep geothermal reservoirs, which are polluting, function in the very same manner as a bottle of sparkling water (albeit at much higher pressure). Drilling to a geothermal reservoir in order to harvest its heat means opening a closed system. The presence of CO2 in deep geothermal reservoirs is a naturally occurring phenomenon linked to Earth magmatic events and decay of any living organism.

Luckily, geothermal CO2 emissions during operation can be mitigated, as Hörmann Grupp presented, there are ways to make a geothermal operation 100% green. Their experiments were based on a pre-existing body of literature on carbon capture. During their tests, they further confirmed that it is possible to capture CO2 released from the brine and reinject it in the geothermal reservoir so that it never pollutes the atmosphere. Furthermore, thanks to the high pressure put on the CO2, it dissolves into the water thus not perturbing the heat exchange critical for any geothermal plant.

Experiments and new technologies are improving geothermal each day making the energy greener and more reliable than ever. It is really a breakthrough that will untroubledly help trigger a massive growth of geothermal in the energy market worldwide.

LPRC during 2020 – a summary

The past year was an atypical one, there is no denying it. Despite the many problems posed by the COVID-19 pandemic, LPRC still managed to keep up with its work plans. All team activities – where the EU-funded projects are of most importance – ran successfully. Although not without a certain degree of adaptation. A quick summary of our activities on each of our EU projects during 2020 is given below:

INTERMIN: LPRC participated in the project’s main discussions and contributed with dissemination activities. The team’s biggest workshare was done in 2019 regarding WP2 – Raw Materials Sector Skills, Gaps and Needs.

MACARONIGHT: In 2020, LPRC coordinated the second installment of  the MACARONIGHT project after its success in 2o19. Coordination included preparation and monitoring of activities in different islands as well as analysis of the outcomes.

PRO-ACT: For this space project, LPRC contributed with geological information for the preparation of the lunar analogues where the robotic elements shall be tested during 2021. LPRC also presented the project during the EGU 2020 event.

ROBOMINERS: LPRC leads WP8 – Active clustering and roadmapping – and during 2020 the team contributed to the exchange of information with several projects and initiatives, kickstarted Focus Groups discussions and launched the Horizon Scanning activities. LPRC also contributed with the dissemination of the project at several opportunities.

AGEO: Within AGEO, the team leads communication and dissemination efforts. In 2020, besides the outreach efforts, LPRC also contributed to strengthening the impact of the project by leveraging communication with other EU projects and initiatives.

CROWDTHERMAL: During 2020, LPRC’s role was two-fold. First, the team largely contributed to the communication efforts with the management of social media channels and preparation of material such as factsheets. Second, LPRC kickstarted activities for WP4 – Integrated Development Schemes, which it leads.

ENGIE: LPRC started discussions and prepared ENGIE-related activities for the Researchers Night in 2020. For this task, LPRC hosted a high number of (online) workshops. The team also contributed with dissemination of the project, as seen with its participation on the EGU 2020 event.

UNEXUP: Continuing LPRC’s tasks from UNEXMIN, in UNEXUP the team also leads dissemination efforts. Therefore, LPRC was responsible for the development of all outreach material – both online and physical. Another important task, was the team’s contribution to the market analysis and go-to-market strategy set for the project’s implementation.

MOBI-US: Within this education-based project LPRC had two main tasks. It led outreach efforts during the whole year with the development and implementation of dissemination actions. The other relevant task was the contribution to the major guidelines for the implementation of the MOBI-US network. Here, LPRC contributed with an extensive analysis on the current and future gaps of the raw materials sector.

Besides contributing to EU-projects LPRC was also active in other areas including policy analysis, science communication and use of foresight methodologies.

We hope to have an even better 2021 with more projects and more work!
