Energy and Environment

An international team of scientists has identified a novel driver of new aerosol particle formation in the Arctic: iodic acid, a chemical compound, which had not previously been observed in the region.

An international expedition with the participation of the Paul Scherrer Institute PSI discovers advanced glacial melting at an elevation of more than 4,000 metres on the Grand Combin in Valais. In the Alps, it may almost be too late for the Ice Memory project, which aims to save ice cores as a climate archive for future generations of researchers.

Future batteries need to store more energy, have longer life, and be safer and more environmentally friendly than today's batteries. The European initiative BATTERY 2030+, in which PSI is participating, is intended to help achieve these goals.

Within the framework of an international project, researchers from the Paul Scherrer Institute PSI are helping to save a valuable environmental and climatic archive. During an expedition 4,000 metres above sea level on Grand Combin in the Alps, they are drilling ice cores from melting glaciers to preserve them in Antarctica.

Decision support for car buyers: Researchers at the Paul Scherrer Institute have developed a web tool called the Carculator that can be used to compare the environmental performance of passenger cars in detail.

Researchers from the Paul Scherrer Institute PSI, on behalf of a research project funded by the Swiss Federal Office of Energy (SFOE), have studied how energy consumption by Swiss industry develops depending on energy prices. One result: Price increases for energy usually affect energy consumption only over the long term.

Researchers at the Paul Scherrer Institute PSI have developed a new method to analyse particulate matter more precisely than ever before. With its help, they disproved an established doctrine: that molecules in aerosols undergo no further chemical transformations because they are enclosed in other particulate matter.

An interview on automotive power systems with Christian Bauer, a scientist at PSI's Laboratory for Energy Systems Analysis who specialises in life cycle and sustainability analyses.

Petrol, diesel, fuel cell or electric – which is the automobile of the future? A PSI study has examined the overall climate impact of various vehicle engines in use today and also projected it to the year 2040.

Making Switzerland's road traffic fit for the future calls for research, first and foremost. In the large-scale research facilities of PSI, chemists and engineers are investigating how to improve the efficiency of motors and reduce their emissions.

Three researchers share this year's Nobel Prize in Chemistry. They are being honoured for their respective contributions to the development of lithium-ion batteries. Petr Novák of PSI likewise works in this area of research and has known the three laureates personally for decades. In an interview, he tells about sitting directly across from one of them at the crucial moment.

A PSI research project investigating atmospheric chemistry will be on board the icebreaker Polarstern on 20^th September 2019. Researcher Julia Schmale talks about the upcoming expedition and her role in it.

Every three years, the World Energy Council explores possible developments of the global energy system under different scenarios. Tom Kober, head of the Energy Economics Group in PSI’s Laboratory for Energy Systems Analysis and one of the lead authors of the study, explains what the individual scenarios mean and how global warming could be mitigated.

PSI researchers have observed mechanical processes in solid-state batteries with unprecedented precision. Using X-ray tomography at the Swiss Light Source SLS, they discovered how fissures inside the batteries propagate. These insights can help to make batteries for electric cars or smartphones safer and more efficient.

At the Jungfraujoch research station, PSI scientists study particulate matter in the atmosphere. And have to deal with the fact that the human body is not made for life at 3,500 metres above sea level.

Researchers at the Paul Scherrer Institute PSI analyse the potential of Power-to-X for Switzerland's energy supply and present their conclusions in a white paper. One finding: The costs for energy from Power-to-X could fall by up to one-third.

PSI researchers drill through millennia-old glacier ice in the high mountains and analyse the world's highest particulate concentrations in Delhi, India. They are helping to address questions regarding climate change and to reduce air pollution.

With the kick-off of the ReMaP project, companies have another opportunity to test their vision for the energy system of the future now. PSI's ESI platform helps to make better and more intelligent use of renewable energy in the future.

In the Nuclear Energy and Safety Research Division at PSI, Johannes Bertsch focuses on the so-called cladding tubes that are used in nuclear power plants.

Electronics should get smaller, faster, and above all more energy-efficient. These themes are also present in several research groups at PSI. From incremental improvements to complete rethinking – who is currently working on what?
