​Travelling to four demonstration sites, our team documented the work of researchers and engineers developing three complementary heat storage technologies: Aquifer Thermal Energy Storage (ATES), Borehole Thermal Energy Storage (BTES), and Mine Thermal Energy Storage (MTES).

 

Through interviews with site managers and immersive footage captured in the field, the films reveal how these solutions could help overcome the seasonal mismatch between renewable heat production and demand, contributing to Europe's transition towards a low-carbon energy system.

Produced for an international research consortium, this series translates complex engineering challenges into clear and engaging visual stories.

 

It highlights both the technological innovations and the people behind them, providing partners and the wider public with accessible insights into one of the key energy solutions being developed to support the European Union's 2050 climate objectives.
