IEA HPP Annex 47: Heat Pumps in District Heating and Cooling Systems
A significant use of alternative heat sources with the help of district heating and cooling networks is a major challenge for a sustainable energy supply. In times of increasing shares of fluctuating producers such as PV and wind energy, the relevance of heat pumps increases. Within the framework of the IEA HPT Annex 47, potentials and barriers for the integration of heat pumps in DHC networks were analyzed.
IEA DHC TS5 - Integration of Renewable Energy Sources into existing District Heating and Cooling Systems (RES DHC)
The expansion of sustainable district heating/cooling is an essential part of the Austrian heat transition. The transformation of these supply systems to fully renewable systems requires the combination of a multitude of aspects. The aim of the project is to compile a data and knowledge base from international projects in this context. Expertise and process know-how for the process of implementing the transformation of district heating and cooling systems will be collected and processed.
IEA DHC Annex XIII Project 02: MEMPHIS 2.0 - Advanced algorithm for spatial identification, evaluation of temporal availability and economic assessment of waste heat sources and their local representation
The identification and integration of waste heat sources is a key measure towards the decarbonisation district heating networks (DHN). Aim of MEMPHIS 2 is to develop an improved algorithm for identification of different current and future waste heat sources; including time relations of the heat emitted and techno-economic details as well as the further development of the online waste heat explorer.
IEA DHC Annex XIII Project 07: CASCADE - A comprehensive toolbox for integrating low-temperature sub-networks in existing district heating networks
The majority of urban district heating networks operate at high temperatures, which are a barrier to the efficient integration of heat sources such as solar, geothermal, ambient or low temperature waste heat. CASCADE is investigating the integration of low-temperature networks into the return pipe of existing district heating networks, which will reduce return temperatures and thus improve efficiency and increase its capacity to connect new customers.
IEA EBC Annex 64: Optimised Performance of Energy Supply Systems with Exergy Principles (Working period 2014-2018)
To reduce CO2 emissions in cities, an overall understanding of energy conversion processes is necessary, which also takes temperature levels into account. This is particularly important when alternative heat sources such as waste heat, ambient heat, solar and geothermal energy are to be used, as these often have a low temperature level, i.e. a low exergy content. Accordingly, urban energy systems are analysed and optimised within the framework of the IEA EBC Annex 64 with the help of the exergy approach.
IEA-ISGAN Annex 1: Global Smart Grid Inventory IEA-ISGAN and Annex 2: Smart Grid Case Studies
The international Smart Grid Action Network (ISGAN) aims to improve the understanding of Smart-Grid-technologies and to accelerate global deployment. The work in ISGAN is structured in eight standing working groups (annexes). The present project describes the Austrian contribution to Annex 1: Smart Grids Inventory and Annex 2: Smart Grids Case Studies.
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 HPT Annex 54: Heat pump systems with low GWP refrigerants
The aim of the project was to investigate the current situation in the area of refrigerants with a low global warming potential ("low-GWP"). The focus of the national project lies on the current refrigerant application situation and on an outlook until 2030 on the availability of components and systems.
IEA DHC Annex TS7: Industry-DHC Symbiosis - A systemic approach for highly integrated industrial and thermal energy systems
Renewable and excess heat sources are currently representing nearly a third of the energy supply used in the DHC sector. Excess heat has the potential to further grow to become an important part of the energy puzzle. Up to 25% of district heating could be covered by industrial excess heat and more than 10 % of the EU's total energy demand for heating and hot water could be covered by heat from data centres, metro stations, service sector buildings, and waste-water treatment plants.
IEA ISGAN Annex 3: Benefit/Cost Analyses and Tools of Smart Grids
Together with experts from 11 countries, the EI-JKU has analysed cost-benefit models and developed proposals for their adaptation and further development. In the course of the work, the EI-JKU dealt in particular with two questions: how such an evaluation model can be adapted to Austrian conditions and which socio-economic factors influence the question of whether an end consumer emerges as a winner or loser from Smart Grid-based functionalities.
IEA ISGAN Annex 5: Smart Grids International Research Facility Network (SIRFN). (Working period 2019-2021)
The Smart Grids International Research Facility Network (SIRFN) aims at improving the implementation of Smart Grids technologies by collaboration between smart grid testing facilities, test beds, and large-scale demonstrations. The focus during the working period 2019-2020 was laid on the implementation of extended interoperability tests and innovative laboratory testing methods for decentralised energy resources. By active participation, Austria’s position and leading role on the forefront of international Smart Grids development was strengthened.
IEA HEV Task 41: Electric Freight Vehicles (Working period 2021 - 2022)
So far, the transformation of freight transport remains one of the biggest challenges on the path to zero emission. The Task's main objectives are to monitor progress and review relevant aspects for a successful introduction of electric freight vehicles (EFV) into the market. Austrian pilot projects on EFV are used to exchange barriers and solution approaches in an international context, especially with regard to substitution potential, costs and energy consumption. Together with incentive systems for the market launch of EFV, this will be discussed with logistics companies, the ministry (BMK) and research institutions.

30. June 2020
Online
This webinar discusses the flexibility measures enabled by smart grids and sector coupling that can help countries and regions make the deep decarbonisation of their energy systems a reality. It will discuss some of the opportunities and challenges of balancing energy and power in a larger perspective and in some local perspectives in the Nordic countries.
IEA Energy Efficient End-use Equipment (4E)
The activities of IEA 4E TCP are carried out in four platforms and joint ExCo projects. The active Platforms are: Electric Motor Systems (EMSA), Sustainable Lighting and Controls (SSL), Efficient, Demand Flexible Networked Appliances (EDNA) and Power Electronic Conversion Technology (PECTA).
IEA HPT Annex 61: Heat Pumps in Positive Energy Districts
IEA HPT Annex 61 evaluates the role of heat pumps (HP) in positive energy districts (PED). Efficiency potentials of the electric and thermal energy of districts that can be unlocked with the use of HPs are evaluated in order to reach a positive energy balance. This refers to both, upgrade of waste heat and simultaneous generation of different energy use in buildings (space heating, DHW, space cooling/dehumidification) and includes self-consumption of on-site renewable electricity generation.
