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.

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.

The key to charging a lithium-ion battery rapidly

Media Releases Energy and Environment Research Using Synchrotron Light

Lithium iron phosphate batteries are very durable and can be charged relatively quickly. Researchers from the Paul Scherrer Institute (PSI), ETH Zurich and Japanese car manufacturer Toyota reveal the reasons for these properties in a new study. The findings were made possible thanks to measurements using a new method at the Swiss Light Source (SLS) at PSI.

Ice in fuel cells imaged directly for the first time

Media Releases Energy and Environment Research Using Neutrons

Researchers from the Paul Scherrer Institute (PSI) have succeeded in imaging the distribution of frozen and liquid water in a hydrogen fuel cell directly for the first time. They applied a new imaging technique that uses successively two beams with different neutron energies to distinguish between areas with liquid water and those with ice extremely reliably. The method therefore opens up the prospect of studying one of the main problems of using fuel cells to power vehicles: ice can clog the pores in the fuel cells and affect their performance. The PSI scientists’ results will be published in the journal Physical Review Letters on 16 June 2014.

Fuel cell know-how from the Paul Scherrer Institute at the core of the SBB minibar

Media Releases Energy and Environment Industrial co-operation

On 4 April 2014 SBB is to launch a new minibar model in its Intercity trains. A fuel cell system including know-how of the Paul Scherrer Institute will also be on board. It will ensure that despite the limited space the minibar will have enough power to brew capuccinos and latte macchiatos, too.

The Paul Scherrer Institute runs two of the energy competence centres of the Swiss government

Energy and Environment Media Releases

As part of the Energy Strategy 2050 the Swiss government and parliament have decided to increase support for energy research in Switzerland. This includes the setting up of seven interuniversity networked Swiss Competence Centres in Energy Research (SCCERs). In the SCCERs ETH Domain institutions, the universities and the universities of the applied sciences are to join forces with industrial partners to develop new competencies and solutions in the decisive action areas of the shift in energy policy. The Paul Scherrer Institute PSI will act as the leading house in two of the SCCERs à storage and biomass à that have already been given the green light. They will begin their work in 2014.

Fuel cell membrane from the Paul Scherrer Institute better than its commercial counterparts

Energy and Environment

A novel polymer electrolyte membrane from the Paul Scherrer Institute PSI has demonstrated longer durability in a laboratory test than the best commercially available counterparts. The breakthrough was achieved by modifying a reasonably priced plastic film through radiation activation and subsequent attachment of functional constituents via a “grafting” reaction. The modified polymer is not only durable à it could also reduce the membrane production costs by 50 to 80 percent. The membrane could be used in applications such as hydrogen fuel cells or electrolysers for hydrogen production from water.

Five times less platinum: fuel cells could become economically more attractive thanks to novel aerogel catalyst.

Media Releases Energy and Environment

Fuel cells that convert hydrogen into power and only produce pure water as a by-product have the potential to lead individual mobility into an environmentally friendly future. The Paul Scherrer Institute (PSI) has been researching and developing such low-temperature polymer electrolyte fuel cells for more than 10 years and initial field tests have already demonstrated the successful use of these fuel cells in cars and buses. However, further research is still required to improve the durability and economic viability of the technology. An international team of researchers involving the PSI has now manufactured and characterised a novel nanomaterial that could vastly increase the efficiency and shelf-life of these fuel cells à as well as reduce material costs.

Memory effect now also found in lithium-ion batteries

Media Releases Energy and Environment Industrial co-operation

Lithium-ion batteries are high performance energy storage devices used in many commercial electronic appliances. Certainly, they can store a large amount of energy in a relatively small volume. They have also previously been widely believed to exhibit no memory effect. That’s how experts call a deviation in the working voltage of the battery, caused by incomplete charging or discharging, that can lead to only part of the stored energy being available and an inability to determine the charge level of the battery reliably. Scientists at the Paul Scherrer Institute PSI, together with colleagues from the Toyota Research Laboratories in Japan have now however discovered that a widely-used type of lithium-ion battery has a memory effect. This discovery is of particularly high relevance for advances towards using lithium-ion batteries in the electric vehicle market. The work was published today in the scientific journal Nature Materials.
