Decarbonisation: charting a course to achieve a net-zero future by 2050
Reducing CO2 emissions and tackling climate change are the goals of energy transition. Green hydrogen has been globally recognised as one of the most important enablers in reaching the zero-emission target by 2050.
Investing in green hydrogen production
Hydrogen is the first element in the periodic table (symbol H). Hydrogen is the most abundant and the lightest chemical substance in the universe, it is a colourless and tasteless gas formed by diatomic molecules H2. Although it is abundant in stars, hydrogen on Earth is not available in an isolated form, we must produce it for various applications.
Hydrogen is an essential energy vector that can drive the transition to a cleaner and decarbonised energy system. Beyond its key role in decarbonisation, hydrogen has the potential for storing vast amounts of energy.
Hydrogen’s versatility and storage capacity hold the key to a sustainable future, unlocking clean energy transition by tackling emissions from major CO2 contributors such as transportation and hard-to-abate industries.

The colours of hydrogen
While hydrogen exists naturally as a molecule, it requires a specific process to become usable as fuel. The type of process used determines the environmental impact and color classification of the hydrogen.

Green Hydrogen
Green hydrogen
Green hydrogen is produced by splitting water using electricity (i.e. water electrolysis) generated from renewable energy sources.CO2 emissions are not associated with either the production or use of green hydrogen. Unlike fossil fuels, green hydrogen offers a decarbonisation pathway for the more pollutant sectors, accelerating the path to climate neutrality.

Our expertise drives our unwavering commitment to green hydrogen converters
Our high-performance converters have been powering high-power industrial applications for over seventy years. Since 1950, we have been manufacturing rectifier systems essential for these projects. In 1955, we designed the first high-current rectifier for water electrolysis.
With decades of technical expertise and a commitment to innovation, FRIEM is now a partner in several large-scale green hydrogen projects worldwide, including the first electrolysis plant in Brazil and major initiatives in the Netherlands, Germany, and other European countries.
We leverage our vast expertise to support energy transition by playing a central role in the green hydrogen supply chain and connecting renewable energy sources with end users through both Power-to-Gas and Gas-to-Power processes.
We plan together with global leaders by sharing experience and knowledge.
We partner with international associations such as (European Clean Hydrogen Alliance, H2IT, Fuel Cell and Hydrogen Energy Association FCHEA), to share knowledge and best practices
Contributing to research projects
We actively participate in European projects (EveryWh2ere) to raise public knowledge of hydrogen technology, thereby maximising its potential for communities.

– Key Concepts
What is Hydrogen?
Hydrogen is the first element in the periodic table (symbol H). It is the most abundant and the lightest chemical substance in the universe.
How can hydrogen be produced?
The most widespread method is reforming, and it involves extracting hydrogen from natural gas, liquefied petroleum gas and naphtha. Other processes include gasification and electrolysis.
What is green hydrogen?
Green hydrogen refers to hydrogen produced through the electrolysis of water supplied by renewable energy (wind, solar and hydropower).
What is water electrolysis?
Water electrolysis is an electrochemical process that splits water into hydrogen and oxygen.
How is hydrogen use today?
Hydrogen is predominantly used by the oil refining, ammonia, methanol and steel production industries.
How will hydrogen be used tommorow?
Hydrogen is essential for decarbonising the energy system and offers ways to decarbonise industrial processes. It also seems to be a promising low-cost option for storing electricity. Furthermore, it can transport energy from renewables over long distances. Hydrogen can be used as an energy carrier in sectors such as transportation and can be used to heat and power buildings.
