Hivoduct at Power Expo Cologne 2025

The Power Expo in Cologne was an outstanding experience for us: three days filled with exciting conversations, inspiring connections, and strong interest in our technology. Our booth became a meeting point for everyone looking to take the next step in safe and sustainable energy transmission.

A true highlight was the presentation by Dr. Walter Holaus (Founder & CEO). In his talk on our Pressurized Air Cables, he demonstrated how Hivoduct is set to revolutionize the energy sector:

• Maximum efficiency & performance – high currents, minimal losses.

• Sustainable & safe – no SF₆ / PFAS, suitable for cities and tunnels.

• Flexible & future-ready – scalable across all voltage levels, from pilot projects to global rollout.

The feedback was overwhelming: grid operators, partners, and industry experts see Hivoduct as a key technology for the energy transition and the modernization of power infrastructure in Europe and beyond.

We sincerely thank all visitors for the engaging discussions and valuable exchange. Together, we are driving the vision forward:
A green, safe, and high-performance energy future – powered by Hivoduct
