Revelation of economic competitiveness of STES against existing heating options. Seasonal thermal energy storage (STES) holds great promise for storing summer heat for winter use. It allows renewable resources to meet the seasonal heat demand without resorting to fossil-based back up. This paper presents a techno-economic literature review of STES.
Here we outline the role and potential of seasonal energy storage to decarbonize the energy system. Energy storage is becoming an important element for integrating variable renewable energy towards a decarbonized energy system – traditionally including the electricity sector but also heat and transport through sector-coupling.
The applications of seasonal thermal energy storage (STES) facilitate the replacement of fossil fuel-based heat supply by alternative heat sources, such as solar thermal energy, geothermal energy, and waste heat generated from industries.
To accommodate the use of this variable energy throughout the year the grid may benefit from economically viable seasonal energy storage to shift energy from one season to another. Storage of this nature is expected to have output durations from 500 to 1000 hours or more.
