Green Hydrogen

With ProMax 6.0, BR&E introduces new process blocks for simulating water electrolysis to produce Green Hydrogen:

Polymer Electrolyte Membrane (PEM)

• Alkaline Water Electrolysis (AWE)

• Solid Oxide Electrolysis (SOE)

Many alternate combinations of properties available for solving the electrolyzer including:

• Total Power Input

• Hydrogen Production Target

• Fraction Inlet H2O Conversion

• Current Density

• Area per Cell

• Cells per Stack

• Stacks per Facility

Electrolyzer performance is characterized by:

• Reversible Cell Voltage from ProMax’ thermodynamic properties

• Overpotential Voltage by

User-specified constant value

• Voltage vs Current Density curve entry

Product Impurities are predicted or specified:

• Hydrogen Crossover
