IEA Bioenergy Task 44 contributes to the development and analysis of bioenergy solutions that can provide flexible resources for a low carbon energy system. The objective is to improve the understanding on the types, quality and status of flexible bioenergy, and identification of barriers and future development needs in the context of the entire energy system (power, heat and transport).
The aim of the IEA Bioenergy Task 42 is to facilitate the market introduction of environmentally friendly, socially acceptable and economical biorefineries. In addition to networking, the interaction between national and international stakeholders as well as the dissemination of the generated results via workshops, presentations, publications, etc. are important activities.
IEA Bioenergy’s vision is to achieve a substantial bioenergy contribution to future global energy demands by accelerating the production and use of environmentally sound, socially accepted and cost-competitive bioenergy on a sustainable basis, thus providing increased security of supply whilst reducing greenhouse gas emissions from energy use.
Hybrid energy networks, i.e. the integration of electricity, heat and gas networks, can make a decisive contribution to optimizing the energy system. The IEA DHC Annex TS3 analyses the potentials and challenges of hybrid energy networks from the perspective of the district heating / cooling system. This includes the analysis of relevant technologies and synergies, an assessment of the different methodological approaches and tools, the analysis of case studies as well as the development of suitable business models and regulations.
The aim of the IEA DHC Annex TS4 is to identify the possibilities of digitalization and the integration of digital process for district heating and cooling. To this end, the Annex TS4 establishes a platform for industrial and scientific experts to strengthen international cooperation and networking and the exchange of experience of national research and development activities.
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 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 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 DSM Task 17 - Extension: Integration of Demand Side Management, Distributed Generation, Renewable Energy Sources and Energy Storages (working period 2013 - 2016)
The aim was to exchange experiences and developments in the field of integrating renewables with the help of DSM in residential and commercial buildings. Technologies like PV systems, electric vehicles, electric storages, heat pumps, micro-CHP in combination with energy management systems (via gateways), and implementing dynamic tariffs using smart meters offer huge potential to increase energy efficiency. Phase 3 of this Task addressed the current role and potential of flexible buildings and their related implied changes and impacts on the grid and markets. The scalability and applicability of successful projects with respect to specific regional differences and requirements was also explored.
IEA DSM Task 17: Integration of Demand Side Management, Distributed Generation, Renewable Energy Sources and Energy Storages
The main objective of the proposed Task is to study how to achieve the optimal integration of distributed generation, energy storages and flexible demand, and thus increase the value of distributed generation and demand response and decrease problems caused by intermittent distributed generation (mainly based on RES) in the physical electricity systems and at the electricity market. The Task deals with distributed energy resources both at local (distribution network and customer) level and at transmission system level where large wind farms are connected.
IEA DSM Task 24: Behaviour Change in DSM – Helping the Behaviour Changers (Working period 2015-2017)
More than 20% of the use of energy for small consumers can be saved by changed behaviours. Past efforts to tap these potentials through DSM-interventions are not effective. The Task 24 dealt with the most important actors groups as well as tools, which support the behaviour changers in their daily work. In addition, an assessment method for DSM-interventions in the frame of the Austrian law on energy efficiency was elaborated.
This task aims at the identification and development of effective business models for energy services, which lead to a sustainable growth of energy efficiency services. Therefore the various national framework conditions and contexts have been analysed, that are necessary for a successful development of such business models. Examples for start-ups and entrepreneurs have been discussed, their challenges and deficits as well as success factors in terms of capabilities/skills identified and out of these findings a web based analysis tool been developed.
Demand Side Management (DSM) refers to the implementation of energy efficiency improvements and service management measures on the side of end users for optimising energy systems overall. This IEA-research programme pushes development of suitable technologies, applications and methods for end users and thus facilitates their preferential adoption in all political decisions on energy policy.
The TCP on District Heating and Cooling (DHC) was founded in 1983. It deals with the design, performance and operation of DHC and Combined Heat and Power systems as powerful tools for energy conservation and the reduction of environmental impacts of supplying heat.
IEA EBC Annex 55: Reliability of Energy Efficient Building Retrofitting - Probability Assessment of Performance & Cost (RAP-RETRO)
The scope of the project is to develop and provide decision support data and tools for energy retrofitting measures. The tools will be based on probabilistic methodologies for prediction of energy use, life cycle cost and functional performance. The impact of uncertainty on the performance and costs will be considered. Methods based on probability give powerful tools that can provide us with reliable ranges for the outcome.
The objective of the IEA EBC Annex 56 project was to develop a methodology for cost effective energy and carbon emissions optimization in building renovation. Within the frame of the project this methodology was developed and furthermore also innovative renovation projects were collected and analyzed, which should perform as best practice examples.
