Scientific Highlights
Power on demand
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
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.
Quartz powder for the battery of the future
PSI materials researchers have developed a method that provides crucial insights into the charging and discharging processes of lithium-sulphur batteries. And the method revealed: with quartz powder added to the battery, its available energy increases and the gradual loss of capacity is much weaker.
Rechargeable batteries that last longer and recharge more rapidly
Researchers at the Swiss Paul Scherrer Institute PSI and ETH Zurich have developed a simple and cost-effective procedure for significantly enhancing the performance of conventional Li-ion rechargeable batteries. Whether in wristwatches, smartphones, laptops or cars, the use of rechargeable batteries will be optimized in all areas of application, considerably extending storage capacity as well as cutting down charging times.
Water pathways make fuel cells more efficient
Researchers from the Paul Scherrer Institute (PSI) have developed a coating technique in the laboratory conditions that could raise the efficiency of fuel cells. The PSI scientists have already applied to patent the technique, which is suitable for mass production.
The key to charging a lithium-ion battery rapidly
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.
Das Kompetenzzentrum Speicherung zieht nach einem Jahr Bilanz
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.
Ice in fuel cells imaged directly for the first time
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
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.
