Energy and Climate

The energy research performed at PSI focuses on processes that can be used in sustainable and safer technologies, ideally with minimal CO2 emissions. The main emphasis is on renewable energy sources. The ESI (Energy System Integration) platform enables research and industry to test solutions for integrating renewables into the existing energy supply. Another focus in this area is the safer use of nuclear energy. These activities are supplemented by analyses giving a comprehensive assessment of energy systems. PSI scientists in the Energy and Environment division study the chemical processes that take place in the atmosphere.

Kein Blick in die Kristallkugel

Media Releases Energy and Climate

Das Paul Scherrer Institut wird in Zusammenarbeit mit dem Weltenergierat nachvollziehbare Modelle für zukünftige globale Energiesysteme entwickeln. In einem auf drei Jahre ausgelegten Projekt wollen PSI-Forscher um Stefan Hirschberg ein Modell entwickeln mit dem man Aussagen über zukünftige Energiesysteme machen kann. Das besondere daran ist, dass es sich um ein sogenanntes Open-Source-Modell handeln wird. D. h. Experten und andere Interessenten können einen Zugang zum Programm erhalten, sowie Informationen darüber, von genau welchen Annahmen die Forscher bei der Ausarbeitung ihres Modells ausgegangen sind. Das ist bei kommerziellen Anbietern von Prognosewerkzeugen nicht üblich.This news release is only available in German.

Klimaforschung am Teilchenbeschleuniger: Beschreibung der Aerosolneubildung muss revidiert werden

Media Releases Energy and Climate Environment

Vom Menschen verursachte Aerosole wirken in der Atmosphäre kühlend: Klimaforscher nehmen an, dass sie einen Grossteil des anthropogenen Treibhauseffekts kompensieren. Allerdings müssen sich die Partikel zum Teil in der Atmosphäre erst neu bilden. Diesen bisher kaum untersuchten Prozess nimmt das CLOUD-Experiment am CERN, an dem auch Forscher des Paul Scherrer Instituts beteiligt sind, unter die Lupe. Dabei wurde erstmals ein Teilchenbeschleuniger für die Untersuchung von Vorgängen in der Atmosphäre eingesetzt. Die Ergebnisse zeigen: die Beschreibungen der Aerosolbildung in Klimamodellen muss revidiert werden.This news release is only available in German.

Auch Feinstaub altert

Media Releases Energy and Climate

Ob fest, gelartig oder flüssig ist entscheidendFeinstaubpartikel tragen wesentlich zur Luftverschmutzung bei. Durch Reaktionen mit anderen Luftschadstoffen verändern sich diese Partikel mit der Zeit, sie altern. Der Alterungsprozess hängt wesentlich von der Luftfeuchte ab, und damit auch die Auswirkungen von Feinstaubpartikeln auf unsere Gesundheit und unser Klima. Dies zeigen gemeinsame Versuche von Wissenschaftlern des Paul Scherrer Instituts PSI und des Max-Planck-Instituts für Chemie sowie der Universität Bielefeld in Deutschland.This news release is only available in German.

Russ lässt Himalaya-Gletscher schneller schmelzen

Media Releases Energy and Climate Environment

Forschende des Paul Scherrer Instituts haben zusammen mit Kollegen aus China und den USA gezeigt, dass die Klimaerwärmung nicht alleine für die Gletscherschmelze im Himalaya verantwortlich ist. Auch Russ, der auf dem Gletscher abgelagert wird, trägt dazu bei. Der Russ entsteht, wenn Öl oder Holz verbrannt werden; Wind transportiert ihn dann in den Himalaya.This news release is only available in German.

Data of the Paul Scherrer Institute from the High-Alpine Research Station Jungfraujoch yield important information.The eruption of the volcano Eyjafjallajokull in Iceland has stalled flight traffic in large parts of Europe. Decision makers had to base their decisions mainly on model calculations for the volcanic plume dispersion. How dangerous is this volcanic ash layer for planes?

News from the smog chamber: mechanisms of particle formation in the atmosphere unveiled

Media Releases Environment Energy and Climate

Up to the present time, the nucleation or new formation of particles in the atmosphere has been a great enigma. Until recently, research was based on the assumption that sulphuric acid played the central role in particle formation. However, laboratory experiments and field tests have consistently provided conflicting results. In the lab, considerably higher concentrations of sulphuric acid are required for nucleation to take place than in the atmosphere itself. Now scientists from the Paul Scherrer Institute (PSI) have found out the cause for these conflicting results from their smog chamber. These findings will advance climate research to a significant degree.

Mystery solved: how fine particulates are formed in the air

Media Releases Environment Energy and Climate

Researchers from the Paul Scherrer Institute, the University of Colorado and 29 other research institutions in various countries have investigated the composition of the organic constituents of the fine particulates found in various regions of the world, and have identified the original substances from which they are formed in each case. For the first time ever, this has enabled them to explain the role played by the individual components of emissions in the development of fine particulates.

Producing Synthetic Natural Gas from Wood

Energy and Climate Renewable Energies

PSI researchers are investigating methods for converting wood waste into synthetic natural gas that could be fed into the public gas grid. Switzerland has enough wood available to cover several percent of its total energy requirements. Energy production from wood is CO2-neutral, due to the fact the CO2 formed during combustion would otherwise be released when the wood rotted down. Unlike the direct combustion of wood, however, use of this synthetic gas produces no harmful particulate matter.

Reliable materials for nuclear reactors

Energy and Climate Nuclear Power Plant Safety

Materials used in nuclear power plants are subjected to extreme conditions. The safety standards for the selection, deployment and monitoring of these materials are extremely high. At PSI, the long-term behaviour of power plant components is being studied. Hence researchers investigate the impact of stress-corrosion cracking in materials, or the effects of strong radioactive radiation on their durability.

Safe repositories for radioactive waste - a study of specifically Swiss conditions

Nuclear Power Plant Safety Energy and Climate

Radioactive waste from nuclear power plants, as well as from medical applications, industry and research, has to be isolated from the environment, particularly the habitat of humans, for a very long time. Specialists at PSI have been concerned with the safety issues surrounding safety certification for geological repositories for many years. Research at PSI focusses primarily on the physico-chemical processes inside such storage systems. The aim is to create a realistic description of the risks associated with storage of radioactive waste.

Structures and impacts of national and international energy systems – national climatic targets for Switzerland

Energy and Climate

The Paul Scherrer Institut analyses the structures and impacts of national and international energy systems. In 2007, for example, a study was carried out in which PSI makes recommendations as to what the national climatic targets of Switzerland could be. The study also highlighted the facts on which the Swiss energy system is based and indicated which targets can be achieved and how. Protection of the climate is, after all, one of the most important areas of national energy policy for the coming years, and the emission of CO2 in Switzerland should be at least halved by the year 2050. Better energy efficiency is an important factor towards this goal – but not the only one.

Frozen memory of the climate

Energy and Climate

Information about the climate and atmospheric composition in previous centuries can be stored in glacier ice. PSI-researchers undertake regular expeditions to various areas within these regions to remove ice cores. These ice cores are effectively solid columns of ice that have been drilled out from a glacier. Once in the laboratory, the cores are thawed out and their composition is analysed, layer by layer. The results provide fascinating insights into a range of aspects of the previous climate.
