Quantifying fugitive hydrogen emissions at the component scale: High-flow sampling method

Hydrogen is a key energy vector in the transition to net zero with its industrial use expected to grow significantly in the next decades. At present there are no standard methods specific for hydrogen fugitive emissions quantification, and these are required to inform monitoring schemes and support regulations. On the other hand, the high flow sampling method (HFS) has been successfully used for natural gas leak rate quantification in the industry. So, in this work we present for the first time a performance evaluation of the HFS method for quantifying hydrogen leak rates.
