Green hydrogen: WS puts electrolyzer into operation

Electrolyzer enables CO₂-neutral burner development

With the help of a new electrolyser and surplus electricity from its own PV systems with a capacity of over 400 kWp, WS will supply the laboratories in Renningen with green hydrogen in future. Following the installation of the electrolyser at the end of 2023, the storage and pipeline infrastructure is now also fully operational.

WS burners are Green Gas Ready for the energy transition

For many years, WS-Wärmeprozesstechnik GmbH from Renningen has been developing and selling highly efficient industrial burners with the label Green-Gas Ready and is thus setting standards in the field of hydrogen combustion for industrial applications. Advances in the combustion of climate-neutral fuels from renewable energies are driving decarbonization and the achievement of climate neutrality in thermal process technology, which is required in a wide range of industries.

Commissioning of the hydrogen electrolyzer

An important step for the company has now been taken with the commissioning of the company's own hydrogen electrolyzer. With the help of the already installed photovoltaic systems with a total output of over 400 kWp, green hydrogen can now be produced when the sun is shining and then used on site in burner development. This means that a CO2 neutral test phase and testing of the hydrogen burners. This is a good signal for the environment, particularly in view of the steadily increasing use of corresponding products in industry and the resulting constant rise in the number of tests in burner development. Thanks to the local production of green hydrogen, the otherwise necessary road transportation of the renewable fuel is also eliminated.

Temporary storage of surplus PV electricity

When the sun shines, the electrolyser modules fill an intermediate storage tank that can store enough hydrogen to supply the test operation for conventional industrial burners for an entire working day. In view of the increasing demand for hydrogen burners and the associated development and testing effort, a further increase in system pressure could even make it easy to multiply the storage options.
