Symposium 1. System Aspects and Sustainability
- Hardo Bruhns University of Heidelberg, Germany
- Cayetano López Martínez CIEMAT, Spain
Rebuilding the energy system is a task requiring an integrated perspective guided by well-developed scenarios which reconcile aspects of security of energy supply, compliance with economic criteria, sustainability of resources as well as climate protection, environmental considerations and social acceptance. This will be a substantial challenge for a future energy supply which will likely be strongly influenced by contributions from fluctuating energy sources. Furthermore, in a European context, liberalization of the energy market will force market partners to accept true competitiveness in the long term. With a view to optimizing both the generation conditions for energy systems such as wind and solar plants and the overall market efficiency, including mechanisms of intelligent demand side management, this calls for moving from present nationally dominated planning horizons towards a transnational European energy partnership interfacing with regions beyond the EU. Tentatively, with some emphasis on the electricity sector but not excluding other energy carriers, the symposium will address the strategic, engineering, economic and social facets of these issues under the following headings:
Scenarios for energy systems
- Stability of electricity supply with significant contributions from fluctuating sources and compliance of electricity production and storage with demand
- Sustainable availability of resources (e.g. raw materials or competition with other uses, in particular regarding biomass)
- Assessment of energy systems including external cost aspects
Perspectives for the longer-term development of energy systems
- Towards a fully integrated European energy system
- Europe’s and neighboring region’s energy visions
- The role of electricity in a future energy system
Climate, environmental and health aspects of energy production
- The impact of greenhouse gases, fine dust, toxics and other pollutants (incl. radioactive) from energy supply and use on climate, environment and health and means for potential mitigation
- The factor of availability of water for energy systems
Symposium 2. Sciences for Energy
- Sven Kullander Royal Swedish Academy of Sciences, Sweden
- Bengt Kasemo Chalmers University of Technology, Sweden
This symposium is especially supposed to provide a forum for novel and groundbreaking ideas in energy research. Part of it will focus on new materials and processes with potential for a future sustainable energy system in a cross-disciplinary approach.
Interested scientists working in the related fields are invited to report on e.g.:
- Materials science for energy conversion and energy efficiency
- Materials aspects related to nuclear fission and fusion
- The progress in the nano-sciences leading to improved materials for solar cells, batteries, fuel cells and thermoelectric materials; and including organic and inorganic light emitting materials for efficient illumination
- The processes of the conversion of sunlight to electricity, heat and fuels – (artificial) photosynthesis, fuels from bacteria, algae and enzymatic processes optimized crops for fuel production
- Improved efficiency of energy generation and usage involving more efficient catalytic processes for chemical substances and energy conversion
- Aspects which have the potential to become “game changers” in the energy landscape including climate related effects and which require scientific exploration, e.g. in mobility and transport.
Symposium 3. Primary Energy Conversion
- Richard Van de Sanden Dutch Institute for Fundamental Energy Research, The Netherlands
- Claude Degueldre PSI, Switzerland
- Claude Ayache CEA, France
This symposium focuses on different aspects on the conversion of primary energy, renewable, fossil based and nuclear. Although it may be anticipated that fossil fuels, currently forming the major part of our energy system, will be required for a considerable time to come, it is clear that an accelerated transition to a more sustainable energy system is required. Conversion of the available primary energy sources to practical applications of that energy are crucial and will shape this future energy system. It is clear that economic as well as technological breakthroughs will be crucial to the social acceptability of the primary energy sources, either for prolonged use of existing sources or accelerated implementation of new ones.
Separate sessions will be conducted on the major primary energy sources: Renewables, Fossil Fuels and Nuclear. Both scientific developments and breakthroughs as well as important developments related to prolonged use, (early) implementation and social acceptability will feature in these symposia. Key note lectures on each subject will describe the field, its importance for the future energy system, the relations between the fields (central vs decentralised generation) and describe the recent achievements and challenges we are facing in each area.
Key questions that may be addressed are:
- Renewables: To focus on enhancing conversion rates or lowering the costs of manufacturing and implementation? How can the potential of renewable energy sources be enhanced by research? What is the role of material developments, including nano technology developments? How can early implementation be stimulated? Can learning curves be influenced to optimise development and deployment rates?
- Fossil fuels: What scientific breakthroughs may aid the prolonged use of fossil fuels? What is the role of natural gas and coal including carbon capture and storage? How can the acceptability of shale oil/gas, tar sand developments etc. be enhanced? Will centralised or distributed energy conversion be the future?
- Nuclear: Which developments in the field of fission and fusion have been achieved and can be further anticipated? What developments in the field of nuclear safety, waste management including transmutation will support social acceptabilty of nuclear as a primary energy source in the European context?
Symposium 4. Energy Networks and Storage (including batteries for mobility)
- Teresa Ponce de Leao National Laboratory of Energy and Geology – LNEG, Portugal
- Martin Greiner Aarhus University, Denmark
Energy Efficiency targets and optimized accommodation of large inputs of renewable energy depend on networks to reliably deliver energy either connecting distant sources (pan - European networks) or microgeneration sources near the load areas where a greater interactivity between load and consumption is needed. Electricity and gas networks will become much more closely interlinked with each other and energy analysis methodologies, linking in an optimal way, both sources is needed.
Storage capacities are an essential requirement to compensate the mismatch between supply capabilities and demand as a means to be effective in the mitigation of renewable intermittency. Storage challenges need new developments at all levels from bulk storage to local small scale storage including electrical vehicles.
The symposium aims to contribute to the discussion of European energy infrastructures needs on technology, new operation paradigms and policies design and also provide information on required technology standardisation and regulatory changes that will unlock the difficult deployment of energy accommodation.
The symposium will cover aspects related to R&D:
- System interoperability among pan- European networks (e.g including HVDC)
- Interconnection between electricity and gas networks
- Bulk Renewable Energy accommodation
- Optimal integration of distributed generation and load demand in small scale local networks
- Storage technologies for large scale integration (thermal, pressure, chemical,…)
- Storage technologies for small scale integration
- Batteries for stationary and mobile applications
- Standardization and regulatory needs
- Emergent issues regarding new carriers like hydrogen and methane from renewable sources (e.g. via hydrogen and CO2 use) and potential avenues towards use.
Symposium 5. Efficient End Use of Energy
- Brigitte Bach AIT, Austria
The symposium is dealing with the efficient use of electrical and thermal energy at different levels and scales of our energy system with a particular focus on the following three topics:
- Session “Energy use in cities” addresses the profound understanding of the complexity of energy characteristics of cities being influenced by various factors such as urban morphology and end-use mix. Scientific methods for modeling and simulation of urban energy flows including supply and demand on a meta-level shall be discussed within the context of urban spatial planning. These research questions shall be further extended to socio-economic and mobility aspects. Furthermore, researchers are encouraged to present new scientific findings regarding the intelligent design and management of city-wide integrated energy systems enabling the maximum integration of renewable energy sources into existing energy systems and leading to the concept of “Smart Cities”.
- Session “Energy use in buildings” takes up the topic of integrated measures for energy efficient buildings at various stages: In the design phase these include architectural and building design aspects; during operation the improvements focus either on the building automation systems or sociological measures to modify user behavior. By introducing advanced controls, the building becomes an integrated component in the context of a Smart City and we can optimize its behavior towards different goals, such as maximizing energy efficiency, maximizing use of renewable energy sources on the spot, optimizing energy usage to reduce peak loads on the electric grid and costs.
