Electrolysis is a process for producing pure hydrogen, which is used as an energy carrier, in the chemical industry and in various other applications. It is particularly important for us to use electricity from renewable energy sources for electrolysis in order to produce truly ‘green’ hydrogen, which is a sustainable energy source. Alkaline electrolysis refers to a specialised process for the electrolysis of water using an alkaline solution (i.e. a basic solution) as the electrolyte.To summarise, the electrolysis of water uses an electrical energy source to break water down into its components, hydrogen and oxygen, by chemical reactions taking place at the electrodes.

We find the right solution for each site and emphasise sustainable, durable and resource-saving technologies. The batteries for the Lubmin and Thierbach projects, for example, come from BASF in Japan. We have a joint venture with NGK – long-lasting with German expertise.

As in any construction phase, there may be traffic restrictions, for example on country roads. We try to manage these as far as possible and adapt them to the local infrastructure so that they are minimised. During subsequent operation, every HH2E plant will be a ‘quiet’ neighbour. Our contacts in the local offices can be contacted at any time to coordinate local interests during the construction phase.

The HH2E plants are being built on freehold land. Naturally, we are trying to minimise the impact on nature. We owe this solely to our vision of producing in a climate-friendly and therefore nature-friendly way. For example, protected forests are preserved and the architectural concept of the projects blends in as well as possible with the surroundings.
