Working Party on End-Use Technologies (EUWP)

The International Energy Agency (IEA) Working Party on Energy End-Use Technologies, often referred to as End-Use Working Party (EUWP), has been in the advisory council for the Committee on Energy Research and Technology (CERT) in the area of end-use energy technologies since 1981. It also functions as reference for questions on end-use energy within the IEA Secretariat.

17th International Renewable Energy Storage Conference (IRES 2022)

20. - 22. September 2022
Düsseldorf, DE

IRES is the world's largest refereed science and technology conference in renewable energy provides a comprehensive scientific treatment of energy storage technologies that can enable the global transition towards the decarbonisation of economies through ubiquitous renewable energy systems. The conference program encompasses all storage technologies in their context, and welcomes case studies, applications, country scenarios, trend analyses, and barriers to be overcome for the transition process.

IEA ES Task 35: Flexible Sector Coupling through Energy Storage Implementation

Task 35 of the IEA Energy Storage TCP addressed Flexible Sector Coupling (FSC) through the implementation of energy storage and examined the role of energy storage in the context of the concept of sector coupling. The demand sectors include electricity, heating/cooling and mobility. FSC was defined, examples of FSC were described and studies on the use of FSC in local and the German national energy systems were carried out.

IEA ES Task 44: Power-to-Heat and Heat integrated Carnot Batteries for Zero-Carbon (industrial) heat and Power supply

The rise of renewable energy causes fluctuating energy production. The electrification of heat supply further challenges the electricity grid. Coupling electricity and heating with thermal storage helps to strengthen grid resilience and ensures stable energy supply. This project identifies and evaluates heat-integrated Carnot battery concepts to store thermal and electrical energy and supply electricity and thermal energy on demand.

IEA ES Task 36: Carnot Batteries

Carnot Batteries are an emerging technology for the inexpensive and site-independent storage of electric energy at medium to large scale (> 1.000 MWh). The technology transforms electricity into thermal energy, stores it in inexpensive media such as water or molten salt and transforms the thermal energy back to electricity as required. Carnot Batteries have the potential to solve the global storage problem of renewable electricity in a more economic and ecologic way than conventional batteries.

IEA ES Task 45: Accelerating the uptake of Large Thermal Energy Storages

The aim of Task 45 is to accelerate the market launch of large-scale heat storage systems. For this purpose, numerical simulation techniques and material measurement techniques are to be improved and a material database expanded. In addition, a standardized evaluation and communication basis will be developed leading to a method for yield assurance. The methods and findings will be disseminated specifically to municipal utilities, planners and operators of district heating systems as well as decision-makers.
