PSI researchers: a new way of hydrogen energy

According to foreign media reports, renewable energy will be expanded and replace nuclear power in Switzerland. This is the Swiss federal government in the 2050 energy strategy decision.

in the Paul Scherrer institute PSI, researchers are investigating by further effective utilization of residual power ( Such as wind and solar power plants) To enhance the utilization ratio of new energy technologies. Hydrogen plays an important role here. It can be through the power hydrogen production technology, production, and used for fuel cells, or in the existing natural gas injection and storage in the network. Through further operation, it can also be converted to methane. PSI researchers are now using the micro gas turbine to test how to increase the hydrogen content in natural gas mixture.

with the Paul Scherrer Institute PSI ESI platform, researchers are seeking solutions for Switzerland's energy future. ESI on behalf of the energy system integration. The platform that experts can individually or in combination to test different alternative energy systems.

the researchers did not directly cooperation with ESI wind turbines or solar cells, but they are designing solutions, the surplus electricity to make wind power and photovoltaic power generation as efficiently as possible reuse and storage. This is why the PSI in the ESI platform, another component of the micro gas turbine. This will methane ( It can be produced from biomass, for example) Into electricity and heat.

this can be added to the natural gas, there is almost no limit. In addition, the methane can be directly obtained from biomass, can be used as organic waste in almost any place won: whether dry forms such as wood chips or aqueous solution, such as waste and sewage sludge. Methane huge advantage: it is more easy than hydrogen storage, because for the same energy, methane need only a third of the hydrogen storage required. However, the additional steps required to obtain a methane from hydrogen takes energy, thus reducing the efficiency of the whole process.
