IEA 4E Product Energy Efficiency Trends (PEET) Project – 4 Reports

The Product Energy Efficiency Trends (PEET) project aims to monitor the energy efficiency of selected product groups in the 4E member countries and regions, to provide information on progress from year to year. The latest PEET reports published in 2022 summarize the state of energy efficiency regulations for four product groups. These are: electric motors, room air conditioners, televisions and monitors, and household refrigerators.

IEA ES Annex 50: Prefab Systems for Low Energy/High Comfort Building Renewal

Development of integrated concepts for multi-storey buildings, which enable renovations of buildings with high energy efficiency at good user acceptance during the realisation phase as well as afterwards (comfort, affordability). Relevant components: integrated solutions of roof and façade with high rate of pre-fabrication, the possibility of integrating the energy façade/roofs and energy distribution and supply.

IEA ES Task 43: Storage for renewables and flexibility through standardized use of building mass

Thermal building mass activation uses building masses to condition interior spaces, but can also function as energy storage through targeted overheating/undercooling. This storage potential can be used for local and grid-connected renewable thermal and electrical energy (Power2Heat). The project develops new content on the construction, control and business models of such storages and disseminates it as guidelines, data and on the basis of best-practice objects that have been implemented.

IEA ES Annex 39: Large Thermal Energy Storages for District Heating

Large-scale heat storage systems will play a central role in increasing the necessary flexibility of district heating networks and enable the further expansion of renewable energies. The main objective of the Annex is to determine the aspects that are important in planning, decision-making and implementing large thermal energy storages for integration into district heating systems and for industrial processes, given the boundary conditions for different locations and different system configurations.

IEA Energy Storage (ES)

The aim of the IEA Energy Storage (ES) Technology Programme is to enable integrated research, development, implementation and integration of energy storage technologies in order to optimise the energy efficiency of all types of energy systems and to promote the use of renewable energy sources instead of fossil fuels.

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 41: Economics of Energy Storage

What is the value of energy storage and how can it be quantified? How can the benefits and value of energy storage be translated into promising business models? The Task will conduct a coordinated methodological assessment of the economic viability of energy storage (electrical, thermal, and chemical) in applications relevant to the energy system. This will be used to derive preferred conditions for energy storage configurations.

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 Annex 49: Low Exergy Systems for High-Performance Buildings and Communities

The objective of Annex 49 is the development of approaches for reducing the exergy demand of buildings, so as to reduce the CO2 emissions of the building stock and support structures for sustainable and reliable energy systems in the building sector. To achieve the objectives of Annex 49, the following activities have been carried out:Application of exergy analysis and providing tools, guidelines, best-practice examples and background information for planners and decision makers in the fields of construction, energy and politics Support of cost-efficient low-energy/exergy measures for renovation and new building taking into account both the residential and the service sector Promotion of exergy-related performance analysis of buildings, particularly from the perspectives of communities / regions

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.
