Abstract
The extension of power generation out of regenerative sources, such as wind power and photovoltaic is a major lever to achieve the ambitious targets to reduce the emission of carbon dioxide. Those sources are extremely volatile. Therefore, systems are needed to stabilize the grids and furthermore help to avoid excess generation and supply bottlenecks. Large-scale electrolysis systems convert water into hydrogen using for instance regenerative energy. Thereby huge amounts of energy will be storable for long periods. Such PEM electrolysis systems must have a power of at least 50 MW and must technically also be able to operate highly efficiently in such an extreme dynamic environment. Siemens is pushing the upscaling and the production of such large-scale PEM electrolysis systems.

Notes
- 1.
An electrolysis system with 100 MW would produce approx. 20.000 Nm3 of hydrogen per hour, that means approx. 3.000 of such systems are needed to produce 500 billion Nm3.
- 2.
With “Emergence” an similar phenomenon is discussed almost in all areas of science; as an example, gases have characteristics like temperature or pressure, but the composing molecules do not have those characteristics.
- 3.
For comparison see DIN EN 15182-3: a combination of two of the biggest fire brigade tubes being operated at peak load would provide 600 l per min.
- 4.
In particular: current, voltage, power, cell voltage, cell temperature, gas monitoring, fill level in gas separators, water pressure, gas pressure, hydrogen detection, fire and smoke detection, process values of cooling circuit.
- 5.
CE stands for the conformity with EU guidelines; a kind of “passport” within the European Union; EU-regulation 765/2008.
- 6.
Extended Primary Safety Measures (EPSM), Extended Secondary Safety Measures (ESSM) and Extended Tertiary Safety Measures (ETSM).
