Whether using electrochemical water electrolysis or thermochemical biomass gasification, continuous online measurement is the only way to protect multi-million dollar stacks and guarantee fuel-cell-grade hydrogen.
As a leading developer of industrial gas and water analyzers, MZD Analytik GmbH provides comprehensive measurement solutions covering the entire process chain, from feedstock to product and from process safety to environmental compliance.
4 Main Hydrogen Production Routes: Process-Specific Guides
While the analytical instruments share underlying physical principles, each production technology has a unique chemical environment and distinct engineering challenges.
Click on the guides below to explore the exact measurement points (MPs) and technical requirements for your specific process:
1. Alkaline Water Electrolysis (AEC) Process Analytics
Unique Challenge: Surviving highly corrosive KOH aerosol environments and managing wet, saturated hydrogen gas streams.
Core Focus: H2 / O2 crossover safety monitoring and electrolyte concentration control.
2. Proton Exchange Membrane (PEM) Electrolysis Process Analytics
Unique Challenge: Preventing irreversible noble metal catalyst poisoning and managing high-pressure output gas.
Core Focus: Closed-loop ultrapure water quality and high-pressure trace moisture (H2O ppm) verification.
3. Anion Exchange Membrane (AEM) Electrolysis Process Analytics
Unique Challenge: Managing membrane sensitivity to carbonation and thermal/chemical degradation.
Core Focus: Carbon dioxide (CO2) ingress monitoring and trace ammonia (NH_3) byproduct tracking.
4. Biomass Gasification Hydrogen Production (BGH2) Process Analytics
Unique Challenge: Processing dirty syngas containing complex multi-component combustibles, tars, and corrosive acid gases.
Core Focus: Real-time syngas composition optimization and scrubber efficiency monitoring.
