LEC is an Official Venue of the “Long Day of Energy” on June 20, 2026

On June 20, 2026, the Large Engines Competence Center (LEC) at TU Graz’s Campus Inffeld will open its doors to the public as part of the “Long Day of Energy” – together with more than 100 other energy showcase venues across Styria. Visitors can look forward to an exciting and truly electrifying day dedicated to sustainable energy and transportation systems, featuring fascinating insights into large engine research and innovative technologies driving the energy transition.
We look forward to engaging with our visitors in person – especially children, young people, and students, who are warmly invited to discover the world of large engine research at LEC.

As an internationally leading COMET research center, LEC demonstrates how industrial research can contribute concretely to global decarbonization – from low-emission propulsion concepts to resilient energy systems for the energy supply of the future. At the same time, LEC educates the next generation of green-tech engineers and offers students exciting opportunities for paid thesis projects as well as hands-on internships for school students in the field of sustainable energy and transportation systems.

What Visitors Can Expect

Fascinating insights into large engine research for sustainable energy and propulsion systems using e-fuels such as hydrogen, methanol, and ammonia
Live demonstrations of innovative test rigs and advanced simulation methods
An interactive journey through the world of energy with LEC ENERSIM
Exciting information on how large engines contribute to the energy transition
Direct exchange with researchers and experts on site

Our Program as an Official Energy Showcase Venue

Guided Tours of LEC’s Unique Research Infrastructure. Tours will take place at 9:00 AM, 10:30 AM, and 12:00 PM (Duration: approx. 60 minutes each)
Optimizing Your Energy System (9:00 AM – 1:00 PM): In direct discussions with our team of experts, visitors can learn how our powerful simulation platform LEC ENERSIM is used to analyze energy systems, optimize efficiency and costs, and compare technologies in a scientifically sound way – and how we can support companies and stakeholders in sustainably optimizing their own energy systems.
Address: LEC GmbH | Inffeldgasse 19 | 8010 Graz, Austria
