Call for Projects & Solutions

Heat transition 2.0: Decarbonizing Heat & Cooling at Scale

The next incubator is the Open Innovation Lab of Energie Steiermark, one of Austria's largest energy service providers. 1.800 employees dedicate their experience and expertise to a fair partnership with approximately 600.000 customers in Austria and abroad. We are looking for companies, start-ups, and innovators to jointly develop products and services for sustainable solutions and business models.

Heating and cooling are among the most important levers for the energy transition. At the same time, they are still heavily dependent on fossil fuels – especially in the building sector, in cities and in industry.

We are looking for scalable, systemic and integrated solutions, which combine decarbonization, digitalization and economic efficiency.
