We were delighted to present at IEEC 2025 in Ostravice, Czech Republic. The conference brought together a vibrant community of researchers and practitioners, with a scientific program marked by insightful contributions and a lively, open exchange of ideas. The social program was entertaining and thoughtfully curated, creating excellent opportunities to connect.
In our talk, “Development and Integration of a Two‑Stage Latent Heat Thermal Energy Storage System in the Built Environment” (NewHeatIntegrated), we highlighted:
- Project vision: a compact two‑stage latent heat storage at ~35°C and ~58°C to reduce peak loads and energy costs, enabled by flexible control, digital twins, and demonstrations.
- Switchable salt‑hydrate PCMs: supercooling and triggered crystallization principles, aligned with building‑relevant phase‑change temperatures.
- Material progress: verified nucleating agents, ongoing thickening strategies, and durability insights from extended cycling tests.
- State of charge: combining direct sensing with calorimetric balance and hybrid physics‑ and data‑driven modeling for robust estimation and control.
- Validation and integration: a dedicated test rig producing high‑quality datasets and a clear pathway to building integration at pilot sites.
Many thanks to the IEEC 2025 organizers and VSB – Technical University of Ostrava for an excellent, well‑run event. More information:
