Financing the future of Geothermal

The Global Geothermal Impact Summit 2024 takes on a mission that is critical to our planet’s future: financing geothermal energy. The conversation about geothermal energy often revolves around its technological advancement, ecological benefits, and potential as a renewable resource. However, there’s a dimension that’s equally vital yet often overlooked: the financial aspect.

The role of the Global Geothermal Impact Summit 2024

The Global Geothermal Impact Summit 2024 aims to be the epicenter of this financial conversation. By gathering experts from the geothermal sector, financial institutions, governmental bodies, and impact investors, the GGIS2024 will create a platform for dialogue, collaboration, and strategic planning. Sessions will explore financing models, risk management, public-private partnerships, impact investment, and more.

This focus on finances isn’t just a theme for the summit; it’s a turning point in how we approach geothermal energy. By addressing the financial aspects head-on, the GGIS2024 stands to shift paradigms, forge new partnerships, and pave the way for a global geothermal renaissance.

Join us in this critical endeavour. Your participation, sponsorship, or exhibition at the GGIS2024 is more than a business opportunity; it’s a stand for a sustainable, equitable, and prosperous future.

The EU Geothermal Strategy

Tuesday, 23 April 2024, 11:00 – 12:30. Break-Out Room 1

The EU is embarking on a phenomenal journey towards geothermal implementation. The European Parliament’s Plenary voted on a resolution, led by Professor Krasnodębski MEP from the European Conservatives & Reformist Group (ECR), to support a European geothermal energy strategy.

In this session, Moderator Margaret Krieger will explore with our partners from France (Jean-Jaques Graff), Poland (Beata Kepinska), the Netherlands (Hans Bolscher), Denmark (Asbjørn Haugstrup), and the European Geothermal Energy Council (Sanjeev Kumar), how the global industry can help to develop an European strategy for geothermal energy to reduce administrative burdens and aid investments in buildings, industry and agricultural sectors across the Union, and set-up the Geothermal Industrial Alliance to fast-track best practices and the effective implementation of legislation. In addition, the IGA is keen to help ensure a harmonized financial risk mitigation insurance scheme that can be globally deployed as well.  

Project finance documentation – why is geothermal energy different?

Tuesday, 23 April 2024, 14:00 – 15:15. Breakout-Room 1

The fundamentals of project finance are fixed cash flows for revenue and tight planning of investment costs based on contracts that are fixed at financial close. Some of those elements work differently with geothermal energy. What documentation solutions and approaches could be used to make geothermal projects bankable after all?

After a more general introduction of the geothermal energy finance market and transaction experience, this session will focus on key characteristics of financing geothermal projects as well as on the financing documentation used.

New Technique For Restoring Lost Production From Formation Scale: Dead and Dying Production and Reinjection Wells To Original Capacity and Beyond

Tuesday, 23 April 2024, 14:00 – 15:15. Breakout-Room 2

This is a significant step forward for the Geothermal industry.

Since the mainstream use of geothermal energy for electricity production began in the 1950s one problem that has so far eluded us is the ability to bring production and reinjection wells back to life after they have experienced blocking due to scaling deep in the formation. Around the world today there exist hundreds of production and reinjection wells where the well structure (casing integrity) is intact but due to formation scale these wells lay redundant.

Solenis has developed a technique with dual ability: to clean formation scale and to stimulate the formation, in both production and reinjection wells.

In the past few years several production and reinjection wells have been cleaned with the new technique and it has significantly increasing capacity above the historic maximums in many cases, indicating stimulation of the reservoir in addition to cleaning of scale. This paper documents case studies and explains the technique and pre work / investigation used to decide whether the technique is appropriate for the well in question.

This is an exciting development for companies with production (or reinjection) wells that are dead or declining due to formation scaling, and/or with clean wells who wish to increase their capacity.

We thank our Silver & Sustainability Sponsor Solenis for hosting and organizing this session.

Project finance documentation – why is geothermal energy different?

Tuesday, 23 April 2024, 15:45 – 17:00. Break-Out Room 1

How to unlock geothermal energy in LATAM?

Wednesday, 24 April 2024, 13:30 – 14:45, Breakout-Room 1

Latin America, with its abundant high-temperature geothermal resources, stands on the brink of a geothermal revolution. However, despite its potential and early advancements, the region’s growth in geothermal capacity has been modest compared to the global trend. This session promises to unravel the complexities behind this scenario, offering a platform to explore and unlock the region’s full geothermal capabilities.

Moderated by the insightful Cecilia Rodriguez-Gomez, the session features a line-up of geothermal experts, including Gurbuz Gonul, Vanessa Interiano, Michelle Ramirez, Oscar Eduardo LLamosa Ardila, Marlene Jamilet Elias de Quan, and Maria Cristina Higuera Cardozo. Together, they will lead a vibrant, interactive discussion, moving beyond traditional presentations to foster real-time engagement and exchange.

Our aim is to critically analyse efforts made in the past decade, understand their impact on the geothermal landscape in Latin America, and identify forward-looking strategies to overcome existing challenges. We seek not just to reflect on past actions but to forge a pathway for actionable solutions, leveraging the shared experiences and insights of our panellists and participants.

This session is set to be a dynamic convergence of ideas and expertise, where every attendee will have the opportunity to engage, ask questions, and contribute to a lively conversation. It’s more than a discussion; it’s a collaborative effort to shape the future of geothermal energy in a region ripe with opportunity.
