With the ‘Hamburg Hydrogen Industry Network’ (HH-WIN) project, the company plans to establish a secure supply infrastructure for the hydrogen requirements of Hamburg's industry in a nationwide and European network by 2030. The hydrogen infrastructure is the central link between all joint projects. The project is to be developed and implemented in stages in line with demand. The current network planning already goes far beyond the initially planned 60 kilometres of network length, of which the first 40 kilometres of supply line will be built with the help of funding from the European IPCEI Hydrogen programme. The expansion areas show medium to long-term potential for the expansion of the Hamburg hydrogen industrial network HH-WIN.
The hydrogen network is expected to replace around 570 million cubic metres of natural gas annually, saving 1.2 million tonnes of CO2. Construction of the Hamburg hydrogen industrial network HH-WIN started in 2024. The route planning for the Hamburg energy networks has largely been completed - now the focus is on the requirements of the first industrial companies to be connected. While negotiations on competition regulations are taking place at a political level, Hamburg's energy grids are dealing with specific issues such as gas quality, pressure levels and grid technology so that climate-neutral gas can flow to Hamburg's industrial companies by 2027.
