Description

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.
