Safely and accurately measure hydrogen blends using emissions-free sampling

G. DUDGEON, Endress+Hauser, Houston, Texas (U.S.); and K. GARRISON, Endress+Hauser, Philadelphia, Pennsylvania (U.S.) As industry continues to explore viable sustainable fuels, hydrogen (H2) has emerged as a front-runner in the alternative energy landscape. H2 blending is a key supporting initiative, which entails injecting H2 into existing natural gas pipeline networks to reduce carbon emissions.  This approach leverages trillions of dollars of existing infrastructure, accelerating clean fuel adoption without extensive capital costs. However, it also introduces a critical challenge: accurately, safely and continuously monitoring the precise composition of the blended gas. The variable nat
