What are the challenges in hydrogen measurement?
PEM electrolyzers require ultrapure water. Conductivity measurements and parameters like pH, conductivity, dissolved oxygen, chlorides, sodium, silica and total organic carbon are crucial. In hazardous areas, it's common to use two separate Class 1, Div. 1 transmitters to monitor electrolyzer feedwater and recirculation where water from separators is repolished. This necessitates separate transmitters for each measurement point, causing increased hardware costs and installation complexity.
How does liquid analysis improve water purity monitoring?
Liquid analysis devices, like Endress+Hauser's Liquiline CM442, minimizes installation complexity and optimizes operational efficiency without compromising safety. The enhanced reliability and accuracy of water quality assessments ensure that the electrolyzer operates at peak efficiency, supporting the broader goal of scaling up PEM electrolysis technology to meet the growing demand for green energy solutions.
