Step by step between now and the year 2050, the Swiss energy system is set to be overhauled. The federal government's package of measures known as
Energy Strategy 2050 provides for a shift away from nuclear power. Energy consumption is expected to be reduced. New renewable sources such as solar energy, wind power, and energy from biomass should be expanded, and existing resources will be better utilised. With the Energy System Integration or ESI Platform, the Paul Scherrer Institute PSI offers research and industry a experimental platform where promising approaches can be tested in all their complex connections and interrelations.

More than just spilling the beans
Because of their high nitrogen content, spent coffee grounds are a popular garden fertilizer. Recycled in this manner, they already contribute to an environmentally friendly waste management. But they have the potential to deliver much more: a new procedure developed at the PSI allows high quality methane to be formed from spent coffee grounds. PSI researchers involved in a pilot project carried out in cooperation with the Swiss food producer Nestlé were able to show that spent coffee grounds left over during the production of instant coffee can be efficiently re-used elsewhere.
Nanomaterial helps store solar energy: efficiently and inexpensively
Efficient electrolysers are needed in order to store sun and wind energy in the form of hydrogen. Thanks to a new material developed by researchers at the Paul Scherrer Institute PSI and Empa, these devices are likely to become less costly and more efficient in the future. Researchers were also able to demonstrate that this new material can be reliably produced in large quantities, showing its performance capability in an electrolysis cell—the main component of an electrolyser.
Welcome to Esiville
A new visitor’s station at PSI tells the story of a Swiss town that makes the change from a conventional energy supply to one with new renewable energy sources.
How Switzerland could supply its electric power in 2050
The Laboratory for Energy Systems Analysis at the Paul Scherrer Institute PSI is investigating how Switzerland’s electricity supply might look, up to the year 2050, under a variety of boundary conditions. On the basis of their calculations, the lab’s researchers are able to generate insights on possible future developments of the energy sector, for example, determine how an ambitious reduction in CO2 emissions could be achieved at the lowest possible cost.
Higher methane yield from bio-waste
Within Switzerland’s bio-waste a huge amount of precious energy is hidden. That’s because valuable methane, the main constituent of natural gas, can be obtained from it. With a technology developed at PSI, the yield of methane from bio-waste could be increased considerably in the future. A long-term test conducted in cooperation with Energie 360° at the Werdhölzli fermentation and wastewater treatment plant is expected to advance this technology further along its path to industrial use.

How can surplus power that can’t be fed into the electric grid be made usable? A fictitious day at the Energy System Integration Platform at the Paul Scherrer Institute PSI.
Renewable energy: Experimental platform ESI is starting up
This fall, the time has come: The Energy System Integration Platform at the Paul Scherrer Institute PSI goes into operation. Today, in the framework of the double conference Networked Energy Research Switzerland, it was presented to the media and around 150 representatives from politics, industry, and science.
Turning Electricity into Gas – and back into Electricity
As capacities for producing solar and wind energy increase, integrating these into the existing energy system is becoming more of a challenge. The ESI platform is testing methods for successful integration. The answer: storing surplus energy as gas.
Structure of the ESI Platform
The road to a sustainable energy future leads through the integration of new renewable energy sources, from the sun, the wind, or biomass. Using the Energy System Integration or ESI Platform, research and industry can test promising approaches in all their complex connections and interrelations.
Biomasse als Stütze der Energiewende
Mit 80 Teilnehmerinnen und Teilnehmern fand am 2. Dezember am Paul Scherrer Institut PSI die erste Jahreskonferenz des Kompetenzzentrums des Bundes für Bioenergie (SCCER BIOSWEET) statt. Das im Rahmen des Aktionsplans Energieforschung Schweiz gegründete Kompetenzzentrum definierte in der Tagung die Ziele, Strategien und Positionierung der Bioenergie-Forschung vor dem Hintergrund der neuen schweizerischen Energiepolitik.This news release is only available in German.
Das Kompetenzzentrum Speicherung zieht nach einem Jahr Bilanz
Am vergangenen 4. November fand am Paul Scherrer Institut das erste Jahressymposium des Kompetenzzentrum des Bundes für Forschung zu Strom- und Wärmespeicherung (SCCER Heat and Electricity Storage) statt. Vertreter aus den beteiligten Forschungsgruppen sowie aus Industrieunternehmen mit einem Bezug zum Thema Speicherung berichteten in ihren Vorträgen über die jüngsten Fortschritte auf dem Gebiet der Wärme- und Stromspeicherung in der Schweiz. Die Tagung zeigte die Intensität der Transformationen, die von der Energiestrategie 2050 in Gang gesetzt worden sind.This news release is only available in German.
New Renewables on integration course
The Swiss government’s Energy Strategy 2050 includes a significant expansion of renewable energy such as solar and wind power. The integration of this electric energy, which is produced in a decentralised way and with temporal fluctuations, poses a major challenge for power grids. One possible solution involves using the electricity surplus that would otherwise overload the grid for the production of gases such as hydrogen or methane. The electric energy would thus be stored temporarily in form of chemical energy. These gaseous energy carriers can be converted back into electricity, heat or kinetic energy (in gas engines) at a later date as and when needed. Dubbed power to gas, the concept is the focus of the new Energy System Integration (ESI) Platform at PSI.
