Thermal Energy Storage for Cost-Effective Energy Management & CO2 Mitigation

  • Annex 30
  • Completed
  • Energy storage in energy systems


The main objective of Annex 30 is to encourage the implementation of thermal energy storage systems and evaluate their potential with respect to CO2 mitigation and cost-effective thermal energy management.

These overarching targets can be supported by the integration of thermal energy storage systems in order to

  • improve overall energy efficiency of the processes
  • increase process flexibility
  • increase utilization of renewable energy technologies (including solar thermal technologies as well as fluctuating power generation by PV and wind) and
  • boost energy system flexibility through peak shaving and demand response applications

Ultimately, Annex 30 will create a methodology for determining key performance indicators of thermal energy storage systems. This comprehensive approach will be focused on 4 sectors: industry, power plant applications, non-residential buildings and transport. The methodology will be applied to various case studies originating from demonstration projects where thermal energy storage systems are applied in a real environment. Industrial involvement is critical to this annex and the crucial goal of harmonizing research and industrial needs will be endeavored.
