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.
Lay summary

Contesto

Il progetto IMES è incentrato sui sistemi per la generazione elettrica decentralizzata 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 sono al tempo stesso caratterizzati da un’elevata complessità tecnica dovuta all’interconnessione di diverse tecnologie e allo scambio di energia (termica e meccanica) e di informazioni sulle condizioni operative. IMES-TEC è un sottoprogetto di IMES.

Obbiettivi

Il progetto IMES-TEC consentirà di sviluppare un’analisi tecnica dettagliata dei sistemi per la generazione elettrica decentralizzata. Il primo obbiettivo è di sviluppare i modelli numerici necessari per calcolare le performance delle macchine (considerando diverse taglie e carichi). In secondo luogo, i modelli dettagliati verranno semplificati ed utilizzati nella piattaforma di ottimizzazione sviluppata insieme ai partner di IMES. Infine, si analizzeranno le barriere tecnologiche che attualmente ostacolano lo sviluppo e l’utilizzo di sistemi per la generazione elettrica decentralizzata.

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

IMES-TEC is part of the umbrella project IMES.

Multi energy hubs are complex systems which endow the integration of several interconnected technologies that exchange electric and thermal power as well as operating information. The IMES-TEC project will develop a reliable technical assessment of the considered technologies for micro-cogeneration and power-to-gas. The first goal is to obtain the simulation tools required to predict the performance at different scale and load. Secondly, the detailed models will be simplified and incorporated into the optimization jointly developed with the other IMES sub-projects. Eventually, the technical barriers arisen from a determined platform will be assessed together with the suitable optimization parameters

Abstract

The long term vision of the Swiss “Energy Strategy 2050” is the phase-out of nuclear power plants along with a reduction in the greenhouse-emissions. The main strategies to achieve this vision are a stabilization of electricity demand thanks to improved efficiency, particularly in buildings, and the increase in new renewable power supply (solar, wind, geothermal). At the same time cost competitiveness and system reliability need to be maintained in spite of the issues associated to the adoption of renewables. In this context, a bigger and more important role will be played by a decentralized energy system that can benefit from the combination of renewable technologies with natural gas Combined Heat and Power (CHP) generation devices. The research topic of this project is focused on the technical evaluation of micro-cogeneration systems based on natural gas and renewables. In addition to the common micro-cogeneration systems, this project will also carry out an assessment of power-to-gas energy storage. The resulting overall system can be regarded as a multi-energy hub.The main objectives of this project, in tight connection with the umbrella project, are:•To provide reliable and detailed thermodynamic simulations of all the natural-gas/biogas based technologies considered in the project, i.e. micro-gas turbine, fuel cells and internal combustion engine.•To provide reliable and detailed thermodynamic simulations of the technologies adopted for power-to-gas energy storage, e.g. hydrolyser.•To define the level of simplification (i.e. reduced order model) required for the simulation of the integrated multi-energy hub and its optimization.•To define the technology barriers for both energy production and storage when connected to the grids (electric grid, natural gas grid and heat grid) and to assess their influence on the system optimization.The work will be carried out during three years by one Ph.D. student and one post-doc which belong to two different groups at ETH Zurich/MAVT.
