Enhance efficiency and safety of green hydrogen production

Unlike other types, AEM electrolyzers use an alkaline solution and a membrane that transports hydroxide ions (OH-). At the anode, water splits into oxygen and hydroxide ions. The membrane carries the hydroxide ions to the cathode, where they react with electrons (from the electrical supply) to form hydrogen gas. AEMs have the potential advantage of using lower-cost catalysts than PEM electrolyzers.

• Maintaining the delicate balance between water supply and water removal is crucial for membrane stability and efficiency. This can be achieved with Promag P 300 electromagnetic flowmeter.
• Gas crossover or cross-membrane permeation can be mitigated by operating the cathode (H₂) side of an electrolyzer at higher pressure than the anode (O₂). Monitoring the differential pressure can be crucial to ensure the electrolyzers are operating correctly, especially when the two sides are operating at similar pressures. This requires careful monitoring with Deltabar PMD75B.

High-temperature electrolysis or Solid Oxide Electrolysis (SOEC) is an emerging technology relying on steam, instead of liquid water or electrolyte. Operating at high temperatures (600-1000 °C) greatly increases the efficiency of the electrolysis process, especially when integrated with waste heat or other high-efficiency heat sources.

• Extreme operating temperatures require strong and durable sensors such as high-temperature thermocouple TAF16.
• Presence of complex gas mixtures require accurate analysis of the evolving gas composition. Our Raman Rxn5 analyzer offers reliable in-line spectroscopy.
• Prowirl F 200 is a reliable Vortex flowmeter suitable for high-temperature steam measurement including wet steam detection.
