Hear from Gradyent, TNO and Siemens Energy as they explore how the heat transition is integrated into the broader energy system in a joint session from the Focus Groups on Heat Transition, System Integration and Digital Energy.

Heating plays a central role across various sectors—whether it's powering high-temperature industrial processes, utilising waste heat, warming greenhouses, or ensuring comfort in our homes.

To achieve climate neutrality, all these sectors must undergo significant transformation along their value chains. Yet, these challenges are often approached as separate issues. But are they truly so different? Or simply two sides of the same coin? What lessons can these sectors share? What benefits might arise if they collaborate more closely? What innovations are emerging within and across these domains? And how can digital technologies help us uncover deeper insights and create stronger connections between them?

In this session, we’ll hear from speakers representing both sides of the equation, each offering their perspective on these questions—and on the potential for digital tools to bridge the gaps between them.

• Edwin Matthijssen and Martijn Clarijs from TNO will present ESDL, a universal Energy System Description Language developed to enable communication between different energy modelling tools, along with their Design Toolkit, a digital tool used for the design and modelling of heat networks.
• Herve Huisman, CEO of Gradyent, will share how his team develops digital twins for both industrial and built environment heating systems, highlighting how lessons learned in one sector can be applied to the other.
• Finally, Boris Rigault of Siemens Energy will present his experience in bringing innovative Power-to-Heat and Heat-to-Power technologies to market, and how these systems are integrated into broader heating systems.

Following the presentations, we’ll open the floor for an interactive discussion. Whether you’d like to learn from others’ experiences or share your own insights we invite you to join the conversation!
