The global energy transition will be based on the hydrogen economy
We are at the beginning of a hydrogen economy. This market will grow rapidly over the next 30 years because the demand for green hydrogen is immense - some talk of up to 500 million tons. 
Hydrogen will play an important role in meeting the EU's and Germany's targets for reducing CO2 and greenhouse gas emissions. The EU aims to achieve 40 GW of electrolysis capacity by 2030. Germany's National Hydrogen Strategy aims to build five gigawatts of electrolysis capacity by 2030. Green hydrogen will be an important lever to develop sustainable solutions, especially in sectors such as industry and mobility that are difficult to decarbonize.
To meet fast-growing demand and reduce costs, it is critical to accelerate the production of sustainably produced hydrogen by industrial-scale PEM electrolysers. The goal is thus to realize electrolysers on a large scale and with high performance.  Every four to five years, the output of electrolysers increases tenfold. Siemens Energy's latest and most powerful PEM (Proton Exchange Membrane) electrolysis product line is optimized for applications up to the higher three-digit megawatt range, so that systems of this size can produce several tons of green hydrogen per hour.

Infographic of Werlte plant to produce synthetic crude oil used for decarbonization of aviation. In the process, green hydrogen is produced from renewable energy by the electrolysis from Siemens Energy. With CO2 (extracted from the air and from a biogas plant), synthetic crude oil is created as the basis for e-kerosene.

The control panel is used to read the current measured values of the Silyzer 200 and to control the production of green hydrogen.
Digital control of the electrolysis is an integral part of the system in Werlte.
