Weather green fuel or energy storage for overrun of solar and wind energy — hydrogen is an essential building block of the energy transition. Therefrom also Siemens benefits. The Technology-Company has been awarded to supply hydrogen electrolysis system to Germany and Switzerland.
Villingen, Switzerland/Düsseldorf, North Rhine-Westphalia in Germany. Siemens has been awarded contracts to supply its Silyzer electrolysis systems to customers in Germany and Switzerland. Siemens is also launching a new, higher-performance system. The Silyzer hydrogen electrolysis systems based on PEM (Proton Exchange Membrane) technology are in compliance with all industrial standards.
The Paul-Scherer Institute in Villingen/Switzerland and Air Liquide in Germany have both opted to use the Silyzer 100 with its power consumption of up to 0.3 megawatts. The new Silyzer 200 generation with an output of over one megawatt per stack is one of the biggest systems available on the market, and is designed to allow configurations delivering up to over 20 megawatts.
Power-to-Gas via Electrolysis
The Paul-Scherer Institute in Villingen/Switzerland has commissioned a Silyzer 100 PEM electrolysis system for its Energy System Integration (ESI) platform. Its aim: to study the integration of decentrally produced renewable energy from highly fluctuating sources such as solar and wind power into the existing energy system within the framework of “power-to-gas” concepts. The project will involve using any excess current produced during peak times to manufacture hydrogen or methane, allowing electrical energy to be saved temporarily in the form of chemical energy. As required, the gases can subsequently be converted into electricity or heat, for instance, or used in the field of mobility as a renewable fuel.
Air Liquide Deutschland, the world market leader in gases, technologies and services for industry and health based in Düsseldorf, has also ordered a Silyzer 100 electrolysis system from Siemens for one of its planned hydrogen filling stations in the North Rhine-Westphalia region. Its intended use is to produce the hydrogen used to power fuel cell vehicles such as buses or passenger cars. Because the only “emissions” produced when using fuel cell powered vehicles are water vapors, they can make a major contribution towards reducing particulate pollution and traffic noise.
