The ScaleUp Heat Storage Vienna presentation outlines the development of large-scale thermal storage as a key enabler of decarbonized district heating and cooling in Vienna. It highlights how seasonal storage supports flexibility, integrates renewable heat (e.g. geothermal and heat pumps), and balances demand, contributing to climate neutrality by 2040. The project focuses on scaling up underground storage solutions, with ongoing research, testing, and planning to enable efficient, urban-integrated implementation.

To establish a fully green energy system in Europe, flexible energy management is vital, especially with intermittent sources like wind and solar. The TREASURE project is developing large underground heat storage essential for utilizing renewable energy in heating communities and industries. Through 7 demonstration projects across 5 countries, we are refining storage techniques collaboratively, leveraging data from existing projects for continuous improvement. With diverse partners including suppliers, builders, researchers, and energy firms, TREASURE aims to streamline the implementation of over 2000 storages, crucial for achieving a carbon-free energy system.
