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.
