Gasnetz Hamburg makes natural gas pipeline fit for hydrogen

Hamburg needs a variety of solutions to reduce CO₂ emissions from buildings and businesses. This is why Gasnetz Hamburg wants to develop a solution option in its "H₂-SWITCH100" pilot project that can also ensure the supply of energy for old buildings that are difficult to renovate and for commercial energy requirements. 

"Converting the natural gas pipelines to hydrogen-only operation is certainly not a solution for the whole of Hamburg", admits Michael Dammann, Technical Managing Director of Gasnetz Hamburg. "But continuing to use existing infrastructure with green gas can be a sensible addition to options such as district heating expansion and heat pumps in certain building structures and locations. With 'H₂-SWITCH100', we want to find out specifically what effort and costs are associated with such a changeover and whether there are any technical hurdles."
