The main objective of the project is to enable the broad application of hydrogen/natural gas blends by closing the knowledge gap that exists in relation to the technical effects on private and commercial gas appliances. The project consortium will identify and recommend appropriate codes and standards to be adapted to the needs and develop a strategy for managing the challenges for new and existing appliances. As a project partner, the DVGW Research Centre is involved in a number of work packages, including the experimental investigation of gas appliances.
