Description du projet:
Seasonal thermal storage integrated into district heating networks is a key requirement for achieving
energy sector decarbonization targets. The « BIG4HEAT » project models and assesses the perfor-
mance of a horizontal underground storage system, a promising solution to minimize land use. It also
explores the potential for repurposing existing infrastructures, such as former fuel tanks, into inter- and
seasonal storage units. The impact of the storage’s geographical position within the network is analy-
zed to optimize hydraulic and energy integration. Finally, the project identifies operational risks linked
to each configuration and proposes strategies to ensure system reliability and efficiency as well as ROI
(Return on Investment) simulation of the different solution with future needs and expansion.
