Advantages of the PEM Water-Electrolysis Technology

Key StatementsHigh dynamic operation• Compact design & footprint• Simple cold-start capability• Self-pressurized operation• Low degradation• Operation from 0% up to 100%

without time restrictions• Power set points reached in

seconds• Pure water handling

PEM electrolyzers have an extremely high dynamic performanceeven when operated under pressure

Basic principles PEM* Technology

SILYZER completes energy storage portfolio andsupports tailored solutions for all major industries

Key Statements• Large scale storage typically comprises

of Pumped Hydro, Compressed Air(CAES) and chemical storage such asHydrogen and Methane

• The potential to extend pumped hydrocapacity is limited

• Hydrogen is used in many industriessuch as the synthesis of fuel for thepetrochemical Industry and theproduction of Ammonia / Fertiliser for thefood industry; renewable onsitehydrogen production is a promisingalternative to trailer/truck/piped energyfuel supply

The future CO2-optimized energy scenario will require smart solutions
