Objectives / concepts

The main goals of the 2020 Power Plant research programme are to maximise the degree of electrical efficiency of the combined gas and steam turbine process and to increase the use of renewable CO2-neutral fuels at maximum efficiency. The programme portfolio also includes the development of CO2 elimination measures in power plant processes and the transport and (geological) storage of CO2. The feed-in of fluctuating renewable energy (such as solar and wind power) is to be supported by ensuring that the necessary reserve energy can be produced through flexible retrievable electricity production in highly-efficient gas cogeneration power plants. By integrating activities and co-ordinating individual projects, the programme aims to contribute towards the strengthening of Switzerland's position as a major research and development centre in the area of advanced gas power plants, and create the basis for the (international) use of CO2-free electricity production processes.

In order to meet the objectives of the research programme within the required timeframe so that the necessary technologies will be fully developed and ready for use by 2020, the necessary basic technologies will have to be available by not later than 2015.

The annual budget of approximately 5 million Swiss francs is to be divided proportionally between industry, the energy sector, the EU framework research programme and the Commission for Technology and Innovation (CTI)  and the Swiss Federal Office of Energy (each approximately 1 million Swiss francs p.a.).

The project activities are especially carried out in conjunction with the SFOE's "Combustion", "Biomass" and "Networks" research programmes, with the corresponding degree of coordination.
