The new construction area “Schleusengraben” is a focus development area of the City of Hamburg along the shores of an old industrial channel. The general development of the “Schleusengraben” is divided into six different areas - each area with its own investor and its own architectural and energy supply concept.
The University of Applied Sciences Hamburg, the energy utility company enercity AG and the gas grid operator Gasnetz Hamburg GmbH have tested a district heating system with a hydrogen content of up to 30 % in the fuel gas in one of these development areas, the “Am Schilfpark” area. In the scope of the energy transition, it is expected that hydrogen will play an important role in the energy and mobility sector.
In the area “Am Schilfpark”, the heat supply system, consisting of two combined heat and power units (CHP) and two gas boilers, was made hydrogen-capable. Additionally, a monitoring system and the hydrogen injection and gas mixing system were installed.
