7 profile visitsPotential applicant for a funded RTDI project

I am an energy systems researcher and project manager at Energy Agency Mälardalen, Sweden. My core background is academic/R&D—focused on solar thermal collectors and district heating simulations—with practical, regional energy project execution.

My organisation

We are currently developing SANDSTORE, an innovative R&D project centered around high-temperature sand-based thermal energy storage (sand batteries). The system is designed to replace fossil/biomass-driven domestic/district boilers and integrate into household level/district heating systems and industrial symbiosis frameworks to provide much-needed grid flexibility.
