IEA DHC TS3 – Hybrid energy networks
Extensive integration of the electricity, district heating/cooling and gas grids, also known as a hybrid energy system, is a key element in decarbonizing the energy system. Through various coupling points such as cogeneration and power-to-heat and power-to-gas technologies, energy can be transferred from one domain to another, where it can then be directly consumed or stored. Thus, synergies are created that enable optimization of the entire energy system.
The aim of the IEA DHC Annex TS3 is to highlight the potentials of district heating and cooling networks within a hybrid energy system and to address the challenges at the same time. The Annex addresses the following content:
a. Technologies and synergy potentials (evaluation of the coupling points, storage and other technologies, identification of use cases and benefits of hybrid energy networks).
b. Tools and methods (for evaluation, planning, design, and operation of hybrid energy networks, e.g., power system simulations, co-simulations, etc.).
c. Case studies (current R&D projects, studies, demonstration plants).
d. Business models, regulatory frameworks, and policy instruments (opportunities and barriers for hybrid energy networks).
The primary outcome of the annex is a handbook that summarizes the results of the subtasks and puts the national activities into an international context. Furthermore, it is planned to prepare short summaries for decision makers; an essential element is the cooperation with IEA ISGAN.
