Increasing green hydrogen production efficiency

It is essential to measure the following parameters: level, flow, pressure, conductivity and in some cases pH.

• Conductivity is a key measurement parameter in ensuring the quality of water. Our digital conductivity sensor Memosens CLSE16 has Memosens 2.0 technology with data storage and contactless transmission.

• Flowmeters are used for monitoring conductive liquids and ensure the reliability of the electrolyzer's water feed. The Promag W 10 is the world's first electromagnetic flowmeter for unrestricted installation measurements.

• Measuring pressure during the preparation of water for electrolysis is essential to detect blockages in filtration and osmosis. Our Cerabar PMP51B is a reliable and easy-to-use sensor for reducing systematic faults in green hydrogen production.

• Measuring level is crucial for maintaining a consistent supply, preventing dry running and promoting resource efficiency. Levelflex FMP51 is suitable for hydrogen and oxygen separators and highly resistant to corrosive substances.

To enhance production efficiency and ensure optimal performance, it is essential to measure specific parameters, including flow, level, temperature, and pressure. All these critical parameters are conveniently provided by Endress+Hauser.

• To ensure efficient oxygen production a vortex flowmeter such as Prowirl F 200 is a perfect match.

• If water in the separators gets to high it can overflow in to the electrolyzer's cells. Liquid level detection with vibrating tuning fork with Liquiphant FTL51B prevents this overflow.

• The temperature of the electrolyzer affects the rate of the electrolysis reaction. Our temperature sensor iTHERM Moduline TM131 can be used to optimize the operating parameters of the electrolyzer.

• Conductivity is a key measurement parameter in ensuring the quality of water. Our digital conductivity sensor Memosens CLS16E has Memosens 2.0 technology with data storage and contactless transmission.

To achieve optimal production efficiency of hydrogen with renewable resources instead of fossil fuels, the measurement of key parameters remains crucial. Parameters such as flow, level, temperature, and pressure, essential for process optimization, can be effectively monitored using Endress+Hauser instrumentation, ensuring reliable performance in PEM electrolysis systems.

• Coriolis mass flowmeters are highly accurate and reliable in measuring mass flow rates. Promass F 300 can be used to optimize the operating parameters of the PEM electrolyzer.

• Measuring level in separators ensures hydrogen purity. Levelflex FMP51 is suitable for hydrogen and oxygen separators.

• If pressure of the gases becomes uneven, there is a risk of explosion. Our pressure transmitter Cerabar PMP51B is a reliable and easy-to-use sensor for reducing systematic faults.
