Hydrogen gas generators

How it works

Electrolysis is a method that uses water (H2O) as a raw material for producing hydrogen and oxygen gas using an electric current.

Discovered in the late 18th century, this method was industrialized for the first time in 1900. In 1939 the first electrolyzers generating 10 000 Nm3/h of hydrogen were installed; this capacity is still used in the largest production facilities in the world today.

However, water electrolysis is still little-used today. Only 5% of the hydrogen produced throughout the world comes from this process. The other 95% of hydrogen is produced by converting natural gas.

Whatever the source of electricity being used for electrolysis, the hydrogen carbon footprint remains more or less high. Thus, with an electric current from renewable energy (solar, wind, hydro, biomass, etc.), green hydrogen (with a very low carbon footprint) is produced.

Water electrolysis, in combination with renewable energy, is therefore a very relevant solution for:

• sustainable ongoing hydrogen production for industries

• storing green energy without increasing its carbon footprint

• supplying energy for green mobility (transportation)

There are different electrolyzer technologies:

• Alkaline electrolyzer

• PEM electrolyzer (Proton Exchange Membrane)

• High temperature electrolyzer (Solid Oxide)

However, currently only alkaline electrolysis technology is sufficiently developed and offers economic competitiveness as compared to traditional hydrogen production technologies with a deplorable carbon footprint!

The emergence of renewable energies should encourage the production of green hydrogen and enable input for future markets, which is key for the environment: notably green mobility (hydrogen-powered vehicles) and renewable energy storage at competitive prices.

Applications

• Industrial hydrogen

• Hydrogen energy

• Hydrogen mobility

• Power to gas

Features

• On site hydrogen production from 0,4 m3/h up to 1200 m3/h

• Delivery pressure from 3,0 bar up to 30 bar without additional H2 compressor

• Hydrogen purity from 99,5% up to 99,9995%

• Modular systems with reduced investment for back-up options

• Integrated systems with high storage capacity options (high pressure compressed gas, metal hydride storage)

Benefits

• Manage your own hydrogen supply

• Pay only for what you consume

• Free yourself of all the logistics related to hydrogen supply

• Secure your hydrogen supply

• Manage peak demand with storage

• Control your backup

• Produce your own hydrogen and optimize your energy bill

• Drastically reduce your carbon footprint

• Eliminate the industrial risks of using hydrogen under pressure

• Have constant pure hydrogen (> 99.999 %)

When you outsource your hydrogen supply, the supplier charges you a “tank bottom” fee for gaseous or liquid hydrogen that cannot be consumed, which can exceed 10% of the invoiced amount.

These tailor-made solutions for your needs offer a real economic attraction: locally produce your own cheaper hydrogen
