Our Vision

With heat constituting 50% of global energy use, decarbonizing heat is a critical step towards a green clean future.

At TIGI, our mission is to revolutionize the industrial and commercial heating landscape through comprehensive, tailored solutions that boost effeiency, reduce costs, and drive sustainability.

We strongly believe that the transition from outdated, polluting fossil fuel solutions to sustainable, renewable-based ones should be seamless, easy, and economical. That’s why we’re committed to developing and supplying the most advanced, effiecient, and cost-effective clean heating solutions while practicing busniess innovation and excellence. Our use of Heat-as-a-Service model allows companies to pay only for the heat they use, avoiding cumbersome tenders and costly, tedious financing processes. We’re here to make your transition as easy as possible.

Our History

At TIGI, we take pride in our legacy in renewable energy innovation. Founded by Shimon Klier, a visionary polymath, we’ve been perfecting renewable heat generation and storage for a decade.

Our patented technologies, including our Honeycomb Thermal Solar Collector and advanced storage systems, have established us as leaders in sustainable heating. In March 2021, we became publicly traded, marking a significant milestone in our growth within the renewable energy market.

In early 2024, we made two strategic moves:

Acquiring SOLID (Austria), which expanded our global reach
Partnering with Eren Groupe for “Heat-as-a-Service” solutions

Together with SOLID, we have completed over 250 projects in more than 30 countries.

Our innovations have earned international recognition, including the 2024 Climate Solutions Prize for decarbonizing heat. Our comprehensive solutions, which combine advanced technology with global execution capabilities, serve large heat users and industries worldwide.

We continue to build on Shimon Klier’s vision, leading the renewable heat revolution and contributing to the global transition to clean energy. With projects across multiple continents, we’re shaping a future of efficient, sustainable energy.
