Energy research performed at the Paul Scherrer Institute is focused on processes that can be used in sustainable and safe technologies for the supply of energy with - ideally - zero CO2 emission. The main emphasis is on the development of processes for the utilization of renewable energy sources, low-emission conversion of energy and the safe application of nuclear energy. These activities are supplemented by analyses giving a comprehensive assessment of energy systems. Atmospheric chemical processes are also being investigated.

Why the Little Ice Age ended in the middle of the 19th century

Media Releases Energy and Environment Environment

In the first half of the 19th century, a series of large volcanic eruptions in the tropics led to a temporary global cooling of Earth's climate. That Alpine glaciers grew and subsequently receded again during the final phase of the so-called Little Ice Age was due to a natural process. This has now been proven by PSI researchers on the basis of ice cores.

Cleaner emissions thanks to sponge-like structure

Media Releases Energy and Environment

PSI researchers have developed a new catalytic converter for cleaning emissions from natural gas engines. It is very active even at low temperatures and remains that way over a long period of time. This allows natural gas to be burned in a cleaner, more climate-friendly way. Thus natural gas and biogas become more attractive as substitutes for petroleum products – for example, as fuel for cars.

Power on demand

Energy and Environment Storage Renewable Energies ESI Platform

If photovoltaic or wind power plants produce more electricity than the network can absorb, valuable energy is lost. At the ESI Platform, PSI researchers are investigating how fuel cells can contribute to making this energy usable in a targeted way through storage.

New technology undergoes real-world testing

Energy and Environment Renewable Energies ESI Platform

The Zurich-based power company Energie 360° provides natural gas, biogas, and wood pellets throughout Switzerland. Now, with the Paul Scherrer Institute PSI, it has successfully tested a new Power-to-Gas technology to be implemented in the area of biogas production. The joint project was awarded the Swiss energy prize Watt d'Or 2018. In this interview, division manager Peter Dietiker talks about the collaboration with PSI.

Efficient energy from biowaste – Watt d'Or for PSI and Energie 360°

ESI Platform Energy and Environment Renewable Energies Industrial co-operation

Efficiently producing energy from biowaste: A technology developed at PSI and tested in collaboration with the Zurich-based energy provider Energie 360° makes it possible. It extracts significantly more methane from biowaste than conventional methods. For this important contribution to a sustainable energy supply, PSI and Energie 360° have now been awarded the Watt d'Or 2018 in the Renewable Energy category by the Swiss Federal Office of Energy.

Stress test passed

ESI Platform Energy and Environment Renewable Energies Industrial co-operation

With a technology developed at the Paul Scherrer Institute PSI, around 60 percent more biogas can be produced from bio-waste than with conventional methods. But can it stand the test in practice as well? A 1,000-hour test at the Werdhölzli biowaste digestion and wastewater treatment plant in Zurich was able to answer this question with a clear yes. It was carried out in cooperation with the Zurich-based energy provider Energie 360°. The analysis of the stress test is now available.

Atmosphere in X-ray light

Media Releases Energy and Environment Research Using Synchrotron Light Environment

PSI researchers have developed an experimental chamber in which they can recreate atmospheric processes and probe them with unprecedented precision, using X-ray light from the Swiss Light Source SLS. In the initial experiments, they have studied the production of bromine, which plays an essential role in the decomposition of ozone in the lower layers of the atmosphere. In the future, the new experiment chamber will also be available for use by researchers from other scientific fields.

More than just spilling the beans

Media Releases ESI Platform Renewable Energies Energy and Environment Industrial co-operation

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

Media Releases Storage Energy and Environment Renewable Energies ESI Platform Materials Research

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.

Lignin, as a constituent of many plants, accumulates in large quantities and could theoretically be used as a precursor material for production of fuels and chemicals. Researchers at the Paul Scherrer Institute PSI and ETH Zurich have developed a method with which the processes that take place in the catalytic breakdown of lignin can be observed in detail. The knowledge thus gained could enable targeted improvement of production methods in the future.
