Ammonia2HeatStorage – Development of a long-term storage system through the combination of CLC and “green” ammonia by means of Membrane Distillation
In order to increase the volatile share of renewables in the energy supply mix, the development of efficient energy storage technologies is becoming increasingly important. The requirements for such technologies are high flexibility, high freedom from losses and, in particular, compactness, i.e., storing as much energy as possible with small system volumes. In the recent […]
IEA IETS Annex XI – Industry based biorefineries
IEA IETS Annex XI was initiated in 2008. In 2020, within the task “Decision Making and Ex Ante Research” and in Steering Committee meetings the following four tasks have been developed: The aim of the Austrian contribution is to develop concepts for industrial biorefineries with maximizing resource efficiency and minimizing energy intensity based on case […]
CERMI_Sol – Solar Thermal Training Program for ECOWAS Countries
Despite the high demand for heat and the presence of abundant solar resource, the use of solar thermal technologies is still on an extremely low level in ECOWAS countries. The immense potential of solar thermal energy in the region could entirely replace the use of fossil resources to heat water. The project therefore aims to […]
IEA EBC Annex 82 – Energy flexible buildings towards resilient low carbon energy systems
In many countries, the share of renewable energy sources (RES) is increasing in parallel with an extensive electrification of the energy demand. The electrification of the demand results from for example the replacement of traditional cars with electric vehicles (EVs) or the displacement of fos-sil fuel heating systems with energy efficient heat pumps. These changes, […]
EFlex-NZEB – Energy-Flexible Zero-Energy Buildings The impact of building design on energy flexibility
In order to quantify and classify the inherent energy flexibility potential in high performing buildings, an evaluation framework for energy-flexible buildings is developed. This approach not only enables comparison across buildings but also allows a general comparison of energy-flexible building technologies. A sensitivity analysis of buildings using dynamic building simulation in high time resolution demon-strates […]
InfraMess – Comparative monitoring study of infrared heating systems vs. a district-heating based radiator systems in a residential building (Kaindorf a.d. Sulm)
A two-year lasting, comparative study of an infrared heating system (electric supply) vs. a radiator heating system (district-heating supply) has been conducted. The study is based on extensive measurements performed at two identical residential buildings of six units each, located in the south of Austria. The study follows a holistic approach and therefore covers a […]
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 […]
IEA DHC TS4 – Digitization of district heating: Optimization of operation and maintenance of district heating and cooling networks by means of digital process management
In the context of the Mission2030 climate and energy strategy, digitization is attributed a key function for the decentralization, flexibilization and efficient use of energy and mobility. While there are already various digitization activities in the electricity grid sector, the district heating sector is still at the beginning in this regard. However, the current transition […]
IEA SHC Task 62 – Solar energy in industrial water and wastewater management
The IEA SHC Task 62 deals with the integration of solar thermal energy into the treatment of wastewater in an industrial context. The main objective is to increase the use of solar thermal in industry, to develop new collector technologies and to open up industrial as well as municipal water treatment as a new application […]
Feasibility Biomasseheizwerk Weizberg
The objective of this project is the integration of a central heat storage into the existing heating plant of the local heating grid in the district of Weizberg, a historic and protected district in the city of Weiz, as well as the implementation of a new control strategy with a fully integrated, intelligent load management […]
