  • The production of “green” hydrogen from renewable energy and water is key technology for the decarbonization of the energy industry. 
  • WUN H2, operating the hydrogen production plant, supports the research by the Center for Energy Technology, University of Bayreuth, and the development of an innovative solution in its plant.
  • They required a solution that provides reliable process data that map, analyze and optimize the electrolysis processes and thus operate the PEM electrolyzers more efficiently and economically.
  • Measurement technologies, including gas analyzers and devices for flow, pressure, temperature and level control 
  • An ultrasonic SITRANS FS230 clamp-on flow meter easily installed on the exterior of the pipeline and without operation interruption or risk of contamination 
  • PCS 7 control system and power supply components
“These three flow measurements are an important input for our simulation models. The simulation results then flow back into the real plant and make it possible to optimize the electrolysis process and thus increase process efficiency and the service life of the plant."
Dr.-Ing. Matthias Welzl, Academic Counselor and Project Manager, Center of Energy Technology at the University of Bayreuth
  • Cost savings and improved safety conditions thanks to a flexible, robust and low-maintenance measurement system.
  • No contamination issues thanks to a retrofitted and externally installed clamp-on system.
  • Quick and easy installation without operation interruption.
  • Increased process efficiency and service life of the plant.
