On 19 May 2026, INTERSTORES contributed to the Symposium Zukunft Wärme in Marburg, Germany, through the workshop: “Monitoring Large-Scale Thermal Storage Systems in Practice – Sharing Experiences”
Organised as part of the national congress programme, the workshop created a dedicated space for discussion on monitoring approaches, practical implementation challenges, and lessons learned from large-scale seasonal thermal energy storage applications.
INTERSTORES was presented through the workshop contribution “Overview of Monitoring: INTERSTORES Large Storage Project”, delivered by Christoph Trinkl (THI) and Christoph Bott (MLU).
The presentation showcased monitoring activities developed within INTERSTORES and highlighted experiences from the Reno-sTES demonstrator at incampus (Ingolstadt, Germany) — a large-scale multi-basin gravel-water seasonal thermal energy storage system integrated into a Low-Ex district heating network.
Workshop discussions focused on:
• monitoring across environmental and energy system domains
• real-time monitoring and remote access approaches
• distributed temperature sensing and field measurement methods
• groundwater observation and integration of historical datasets
• practical implementation lessons for long-term operation and data traceability.
Alongside her colleges, Natalie Peracha (THI) presented a techno-economic analysis of a large-scale thermal storage facility using existing infrastructure on the incampus case (“Technisch-ökonomische Betrachtung eines thermischen Großspeichers unter Nutzung bestehender Infrastruktur”). Natalie’s presentation, connected to INTERSTORES WP6, explored how different economic evaluation approaches influence decision-making for seasonal thermal energy storage systems. Using the Reno-sTES demonstrator at incampus as a demo site/use case, the work examined techno-economic performance under different design choices and highlighted the importance of combining investment and technology evaluation methods to support more holistic decision-making for thermal storage deployment.
The event also included participation and round table discussions with stakeholders active in large-scale thermal storage monitoring and deployment, creating valuable opportunities for knowledge exchange between research and implementation communities.
Approximately 60 participants attended the event, representing scientific organisations, industry, public authorities, and media.
Thank you to everyone who joined the discussions and contributed to advancing practical approaches for seasonal thermal energy storage monitoring.
