Lay Summary (Italian)

Lead
La strategia energetica 2050 (Energiestrategie 2050) introdotta dal Parlamento svizzero nel 2011 prevede l’abbandono graduale dell’energia nucleare portando a spegnimento le cinque centrali esistenti. Al tempo stesso, si prevede di diminuire le emissioni di gas serra (CO2) grazie al maggior apporto delle fonti rinnovabili, in primo luogo idriche e geotermiche, e alla diminuzione del consumo di energia primaria tramite miglior efficienza energetica. Al fine di realizzare la conversione al nuovo sistema energetico si dovranno affrontare diverse sfide: i) gestire la variabilità delle fonti rinnovabili garantendo la stabilità del parco elettrico, ii) integrare i numerosi sistemi decentralizzati per la produzione di energia, ed infine iii) ridurre gli sbilanci giornalieri e stagionali tra domanda ed offerta.

Contesto

Il progetto Integration of sustainable Multi-Energy-hub Systems at neighbourhood scale (IMES) è incentrato sui sistemi per la generazione elettrica decentralizzati che integrano fonti rinnovabili, l’utilizzo di gas naturale (o biogas) e lo stoccaggio energetico ‘power-to-gas’. Tali sistemi rappresentano una promettente soluzione ma per ottenere una valutazione critica è necessario condurre un'analisi multi-disciplinare che si estenda dal settore ingegneristico alle scienze sociali ed economiche.

Obbiettivi

Grazie al progetto IMES, analizzeremo i sistemi di produzione decentralizzata con una metodologia innovativa ed esauriente che possa affrontare contemporaneamente questioni tecniche, economiche e sociali. Le simulazioni numeriche e le linee-guida sviluppate consentiranno di valutare chiaramente la convenienza ed i problemi legati all’adozione di tali sistemi. Infine, utilizzando dati reali, caratteristici dei tipici centri urbani svizzeri (città-cittadina-villaggio), svilupperemo diversi casi studio che mostreranno quali configurazioni tecniche garantiscano un impianto efficiente, economico e fattibile dal punto di vista sociale.

Lay Summary (English)

Lead
The long-term vision of the Swiss “Energy Strategy 2050” is the phase-out of nuclear power plants along with a reduction in greenhouse-emissions. This will lead to the following challenges: i) handling the transient nature of both loads and (renewable) energy generation, ii) maintaining system stability, iii) integrating decentralized energy production, and iv) reducing the daily/seasonal load and generation imbalances. A promising solution addressing these concerns is the decentralized power production based on renewables and natural gas coupled with energy storage.
Lay summary

With this project we will develop and provide a comprehensive simulation approach for decentralized power production which tackles at the same time technical, economic and social issues. We will establish a new methodology to evaluate decentralized power production solutions and formulate techno-economic decision guidelines for implementation of decentralized power production integrating renewable energy sources, natural gas-based micro-cogeneration and storage (power-to-gas and batteries). These guidelines will contain recommendations on how neighbourhood-scale power productions should optimally be implemented today and in the future, which are the technical, economic and social barriers to be overtaken and where innovation is necessary to bring distributed power generation to the market.

Abstract

The new Swiss “Energy Strategy 2050” faces the following challenges: i) handling the transient nature of both loads and (renewable) energy generation, ii) maintaining system stability (e.g. by providing enough storage capacity), iii) integrating decentralized energy production, mainly at building level and iv) reducing the respective daily and seasonal load and generation imbalances by demand side management and storage. A promising solution addressing these concerns is the decentralized power production based on renewables and natural gas coupled with energy storage (or multi-energy hubs). A decentralized system would allow to: i) balance excess power production (e.g. solar power or wind peak generation) with energy storage (e.g. power-to-gas, batteries) or demand side management, ii) efficiently co-generate electricity and heat (for co-generation or tri-generation) thus reducing CO2 emissions, iii) ease the transition toward larger use of biogas, iv) limiting the cost increase by combining complementary production and demand, and, eventually, v) enhance social acceptance of the energy turnaround through minimizing the plant footprint. Thereby the interaction between energy demand of buildings, the integration through local energy grids, and decentralized energy production is a major challenge. To find the best combination of technologies in such a complex system and to provide a comprehensive analysis of the decentralized energy production value chain, this umbrella project will coordinate the following specific studies (assigned to five different sub-projects involving seven research groups): i) the time-resolved future building energy demand and integration of technologies into buildings (using the energy-hub concept), ii) the technology performance prediction and integration, iii) the economic and market analysis, iv) overall energy-hub system control and v) the social impact evaluation.Important industry partners (EWZ, Alstom, Zurich City, VSG and Amstein+Walthert) support the project, and will contribute with data and advise. All possible synergies will be sought and exploited with the NFP70 project "Assessing Future Electricity Market Models" and all relevant Swiss Competence Centres for Energy Research. Bringing together all the required expertise, from the thermodynamic to the economic and social point of view, this project will permit to clearly assess the potential role of decentralized multi-energy systems for future power generation. Let alone that the correct implementation and optimization of such systems will represent one of the solutions to make the future energy strategy successful.
