The webinar will take place on November 17th and will showcase eco-friendly heating solutions. Registration is still open!

GreetGEO is hosting a webinar focused on sustainable heating in urban areas, exploring how CO₂ generated during energy production can be reused for heating residential buildings. The event will feature presentations from two companies showcasing their innovative technologies.

The webinar will take place on November 17 at 14:00 CET and aims to raise awareness and understanding of innovative waste-based technologies for district heating. Participants can register through the online form by clicking the link or scanning the QR code.

Two companies, Thermowatt and eChemicles, will present solutions capable of providing heating for cities with more than 100,000 inhabitants. Their approaches rely on two distinct technologies: CO₂ conversion and wastewater utilization, both applied to heating apartments. These geothermal-based technologies focus primarily on Central and Southern Europe.

Thermowatt has patented a system that recovers energy from wastewater for heating and cooling buildings, with a total thermal capacity exceeding 10 MW.

eChemicles has developed an electrochemical process that converts CO₂ into e-chemicals such as carbon monoxide, ethylene, and other valuable products. The company received the EIT Manufacturing Day BoostUp! award this year and is among the finalists in the Climate, Energy and Mobility category of the European Commission’s Innovation Radar Prize 2025.

The webinar is organized in collaboration with the REHEATEAST and HEAT 35 projects under the Interreg programme and the Greet CE project supported by Horizon Europe. The Hrvoje Požar Energy Institute is a common partner for all of these projects and coordinator of GreetGeo.

GREET GEO will host a targeted workshop titled “De-risking Geothermal Investments: Strategies for SMEs & Start-ups” at the upcoming European Geothermal Congress (EGC 2025) in Zurich. The session will take place on 8 October 2025, from 10:30 to 11:00, in Seezimmer 1B.

This interactive workshop is designed to support small and emerging players in the geothermal sector by raising awareness of investment risks and introducing practical tools and financing options to mitigate them. Participants will engage in group exercises to identify common barriers and propose actionable recommendations, contributing directly to the development of regional policy and support mechanisms.

Workshop Highlights:

• Presentation of EU and national de-risking tools
• Interactive group exercise on barriers and solutions
• Group sharing and discussion
• Wrap-up and next steps

The workshop aims to generate a list of key barriers and drivers for geothermal investment, enhance awareness of available tools and strategies, and gather input for future policy recommendations. If you want to join, register here now.

This session is part of GREET GEO’s broader effort to foster innovation and reduce financial risk in the geothermal energy landscape, aligning with the goals of EGC 2025 to accelerate the energy transition across Europe.

The Canary Islands took a significant step toward unlocking their geothermal potential with a Regional Stakeholder Workshop hosted by the COMPASS Geothermal project in collaboration with Greet GEO. Held at the Instituto Tecnológico de Canarias, the hybrid-format event convened 48 participants from across Europe, including geothermal developers, drilling experts, researchers, public authorities, and energy stakeholders.

The workshop focused on the challenges and opportunities of deploying deep and superhot geothermal energy in island environments. It featured technical presentations from COMPASS partners on corrosion mitigation in Enhanced High-Temperature Loop Architecture (EHLA), flexible well completions, and techno-environmental assessments.

A panel discussion brought together leading voices in the sector, including Baldur Hauksson, CTO of Reykjavik Geothermal, and Santiago Díaz Ruano, Head of R&D&I at Instituto Tecnológico de Canarias. Topics ranged from regulatory gaps and energy pricing to community engagement and public acceptance.

Moderated by Amel Barich, Ph.D. (GEORG) and Dario Bonciani (COSVIG), the event emphasized the importance of cross-sector collaboration and knowledge exchange in accelerating geothermal innovation. The workshop also highlighted the role of regional initiatives like Greet GEO and La Palma Research Centre (LPRC) in supporting sustainable energy transitions.
