Appliance & Equipment Testing – Hydrogen Blending

European Hydrogen Blending Appliance Testing, THyGA – Existing Appliance Testing:
Dr. Jean Schweitzer, Senior Project Manager, Danish Gas Technology Centre, Denmark
THYGA is a EU supported project aiming at clarifying the possibility of blending hydrogen in the NG grid for domestic and commercial users. 100 typical appliances have been tested with blends up to 60% H2.

European Hydrogen Blend Testing, Industrial Heating Processes
Dr. Sander Gersen, Senior Combustion & Gas Quality Specialist, DNV, Netherlands
What are the challenges when using hydrogen as a fuel for industrial heating processes?
Existing industrial production processes such as the metal, glass and ceramic industry have a major challenge to decarbonise existing heating processes. A fast and sustainable route to reduce the carbon intensity of these processes is to replace natural gas with hydrogen. In this presentation the technical challenges will be discussed when adding hydrogen to natural gas with regard to the performance of industrial natural gas burners. In the presentation the changes in combustion performance will be presented when adding hydrogen to natural gas ranging from 0-100% hydrogen.

Quebec Hydrogen Blending Appliance Testing – Res’l & Comm’l Performance, operation and safety
Nicolas Bombard – Project Engineer for RNG, hydrogen and gas networks – Natural Gas Technology Centre (NGTC), Quebec, Canada
Lucas Tremblay-Roberge – Project Manager for Hydrogen and natural gas heat pumps – Natural Gas Technology Centre (NGTC), Quebec, Canada
Part of a three-phase project including hydrogen testing of appliances, network components, measuring instruments and leak detection devices, this presentation focuses on the test results of nine commonly used residential and commercial appliances. The testing procedures undertaken in NGTC’s laboratory were directly derived from the relevant Z21/Z83 safety certification Standards, except a blend of hydrogen and natural gas (ranging from 0% to 40% hydrogen) was used in lieu of typical Test Gas A. Some of the standardized tests performed include burner ignition, combustion quality, emissions, abnormal operating conditions, and burner temperatures. Appliance performance was also monitored as part of the same effort, including metrics like hourly input, thermal efficiency, radiant temperatures (for fireplace and infrared heater), and boiling and oven setpoint times (for gas range).
