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.
