PEM Water Electrolysis for Hydrogen production system
German CLEANITIATIVE’s PEM water electrolysis for hydrogen production
equipment is a powerful modular hydrogen production system that minimizes risks
and costs through a multi-stack, modular and extensible design. The system is
mainly composed of proton exchange membrane reactor, water treatment and
electrical controls, and is integrated in a 40-inch container. It can be
installed indoors or outdoors according to user’s requirements. Its maximum
capacity: producing 4,920 Nm³/h hydrogen with a purity of 99.9998%, which is the
best choice for various industrial, fuel and renewable energy applications. Our
company has provided more than 3,000 sets of hydrogen production systems with
various specifications to users all over the world, which has been proven to be
a reliable, economical and efficient turnkey solution for green hydrogen
production.
WORKING PRINCIPLE
SYSTEM FEATURES
1. Pure water electrolysis is adopted, which is pollution-free and corrosion-free,
and the hydrogen purity is high;
2. This hydrogen production system with low conversion cost, optimal integration
and high efficiency, makes green hydrogen production more economical and
efficient;
3. The user’s actual hydrogen demand can be realized through modularization,
flexible expansion and regulation of the system.
4. Corrosive chemicals and corrosive chemical electrolytes are not used in the
hydrogen production process, so the production is more green and environmentally
friendly;
5. This system with low maintenance cost, compact structure, low noise, convenient
installation and is less limited by installation space.

APPLICATION
1. Driving equipment fuel
CLEANITIATIVE’s PEM water electrolysis hydrogen production equipment is
zero-emission and pollution-free hydrogen production system. Mobility leaves a
footprint – at least up to now. Hydrogen from our PEM electrolysis can be used
directly for fuel cells and is therefore emission-free and climate-friendly.
That makes traffic cleaner and quieter.
2. Decarbonization of domestic energy systems
Water electrolysis produces not only hydrogen, but also ca 50 °C heat as a
by-product. This is valuable energy that can be fed into the district heating
network or used directly to heat residential and commercial premises. Fuel cell
heating systems also benefit from the principle of cogeneration.
3. Decarbonization of industrial processes
The production and processing of industry raw materials and goods, the hydrogen
can be used as reducing agent and protective gas, which can greatly reduce the
generationand emission of greenhouse gas (CO2), improve the industrial
production process to be green and pollution-free, thus benefit some enterprises
under the background of carbon neutrality, e.g. heating of kilns in glass,
cement or steel production.
4. Raw material for synthetic industrial goods
Mixing hydrogen (H2) and carbon dioxide (CO2) produces a high-quality syngas.
this is a pioneering process for capturing CO2 emissions and using them to
produce the chemical building blocks for chemicals, polymers or synthetic fuels.
Even the production of ammonia (NH3), the main ingredient for mineral
fertilizers, is possible with climate-friendly green hydrogen.
5. Energy storage for balancing the power grid
Surplus electricity is converted into green hydrogen via electrolysis with
water. This can be stored conveniently and over a long period of time in the
natural gas grid or in tanks, and accessed again when renewables aren’t
available.
