ESI Platform

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.

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.

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.

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.

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.

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.

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.
