IEA HPT Annex 58: High-Temperature Heat Pumps

Industrial heat pumps, especially high temperature heat pumps with useful temperatures higher than 100°C, are a central element in the future energy system. In order to increase the application of high temperature heat pumps in industry, this project will provide an overview of the technological possibilities up to the procurement process of high temperature heat pumps. This should increase the understanding of the technology and its potential and reduce existing market barriers.

The goal of the Annex Electric Motor Systems is to raise awareness on the large savings potential in motor systems, while showing the realization method of such a path. After publishing the „Policy Guidelines for Electric Motor Systems“ and recommendations for carrying out energy audits for motor systems based on international standards Austria analysed the impact of industrial automation on electricity consumption and the motor market.

IEA AMF Task 63: Sustainable Aviation Fuels (SAF) (Working period 2021 - 2023)

Sustainable aviation fuels can reduce aviation GHG emissions. However, this potential remains largely untapped as such fuels currently account for only 0.1% of total aviation fuel consumption. The aim of the task was to lay the foundation for joint R&D work and facilitate the introduction of sustainable aviation fuels by identifying stakeholders, assessing national situations and sharing information.

IEA UsersTCP: Social License to Automate (working period 2019-2021)

Automation applications for load shifting, also in the homes of end customers, will play an important role in the current transformation process of the energy system. The project “Social License to Automate” examined the question, which aspects are important for the success of these innovations and technologies, and under which circumstances end users are prepared to accept or reject energy-related automation processes.

IEA User-Centred Energy Systems "TCP Day": Solutions for an inclusive energy transition

6. April 2022
FFG - Sensengasse 1, 1090 Wien (Building: "Haus der Forschung"; Room: "Franziska Seidl")

The Users Technology Collaboration Programme (TCP) day was dedicated to socio-technical topics of the energy transition, such as the involvement of users in innovation processes. Topics of the TCP day were current activities and highlights of the work within the Users TCP and input from other IEA TCPs with Austrian participation, addressing the topic of "inclusive energy transition".

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 HPT Annex 67: Digital Services for Heat Pumps

Digital services such as advanced modelling, big data methods and augmented reality are not yet widespread in the heat pump industry, although they can be essential for market penetration and decarbonisation. It will be analysed how such services can be used over the life cycle, especially for product design/testing, integration, and operation/maintenance. Expertise from R&D and practice will be collected in an international database and disseminated in the industry.
