Hydrogen Production via Methane Pyrolysis: An Overview of ‘Turquoise’ Hydrogen

‘Turquoise’ hydrogen processes generate H2 without releasing CO2. Presented here are the opportunities and challenges for producing hydrogen by methane pyrolysis Hydrogen-producing processes are classified using a color scheme according to their carbon footprint (Table 1; [1–3]). So-called “turquoise hydrogen”…

Management and Maintenance Strategies for Valves

Asset criticality and risk are primary among the many factors that must be considered to appropriately manage valves throughout their lifecycle Asset strategies usually define how assets will be treated in the different phases of an asset lifecycle, from acquisition…
