Hydrogen I Our solutions

Converters for green hydrogen production

The green hydrogen challenge

Reducing global CO2 emissions to net zero by 2050 is consistent with efforts to limit the long-term increase in average global temperatures to 1.5˚C.

In this path, hydrogen stands for the core of change,  being a central topic in political, energy and industrial debates.

Counting on a huge know-how in the energy conversion, we hold a key role in the green hydrogen supply chain, between renewables and end users. We supply the rectifier and all the equipment for the Converters for green hydrogen production.

Learn how we support the energy transition

Transforming the energy of tomorrow

Worldwide governments are keenly interested in ways of reducing the net emissions of greenhouse gasses, and to develop a national strategy able to empower valuable hydrogen supply chains.  Hydrogen definitely proves to be decisive in production and energy consumption, as it is versatile and can be integrated into the other clean energies. Green hydrogen production through water electrolysis, will be one of the keys to support the energy transition. In fact, green hydrogen produced by electrolysis and renewables is 100% CO2 free.

Rectifiers for large scale electrolysis

Robust, efficient and purpose-built, FRIEM PSU (Power Supply Unit) pairs with main electrolytic cells’ technologies (alkaline, PEM and SOEC). It can be delivered fully equipped with: rectifier transformer, DC no load isolators, thyristor rectifier, automatic harmonic filters, heat exchanger, local control cabinet, polarization rectifier and cooling cabinet. If required, in order to limiting the footprint, the PSU can be fully containerized.

Key concepts

Hydrogen is the first element in the periodic table (symbol H). It is the most abundant and light chemical substance in the universe.

Reforming is the most widespread method to extract hydrogen from natural gas and from liquefied petroleum gas and naphtha. Other processes include gasification and electrolysis.

When hydrogen is produced by electrolysis of water using electricity produced from renewable energy (wind, solar, hydropower).

Water electrolysis is an electrochemical process that splits water into hydrogen and oxygen.

Hydrogen use today is dominated by industry, for oil refining, ammonia, methanol and steel production.

Hydrogen is essential to decarbonize the energy system. It offers ways to decarbonise industrial processes, it looks promising to be a lowest-cost option for storing electricity, can transport energy from renewables over long distances. Hydrogen can be used as energy carrier in sectors like transport, and to heat and power buildings.
