Hydrogen | SICK
Hydrogen can be produced using various processes. Steam methane reforming is an established method as an alternative to Co 2 -free water electrolysis. SICK offers extractive gas analyzers such as the S700 and the GMS800 for measuring methane (CH₄) and carbon monoxide (CO) to monitor the steam reformer and control the downstream shift converter.
