The hydrogen revolution is underway: according to the International Energy Agency, global demand for hydrogen tripled between 1975 and 2020 and is still growing.

The huge growth of this new energy carrier is driving the public and private players in the sector to develop the regulatory framework and processes for the production, transport, storage and uses of hydrogen.

While the use of hydrogen is not fundamentally new, the strong ambitions around decarbonised hydrogen illustrate a switch in scale initiated by the public authorities and operators: this low-carbon hydrogen, produced by electrolysis of water thanks to electricity from renewable or nuclear energy sources, is definitely one of the keys to the energy transition.

To enable this development, the players in the sector will be able to count on Assystem's expertise to support them throughout the hydrogen value chain: development of production or distribution infrastructures, management of regulatory, safety and security constraints, and anticipation of the uses of hydrogen in transportation or industry.

Be part of the green H2 revolution, at every stage of the value chain

The global hydrogen market is rapidly expanding: currently valued at $130 billion, it could reach $2,500 billion by 2050 according to projections by the Hydrogen Council. In response to these forecasts, we need to create ecosystems that include decarbonised energy producers, hydrogen equipment suppliers, hydrogen producers, and hydrogen consumers. The revolution in this energy carrier will be enabled by the fall in its future costs and by the commitment of governments to promote green, decarbonised energy.

Integrate and anticipate the uses of clean hydrogen (green, pink and yellow)

The use of clean hydrogen is an opportunity for many sectors such as mass-transportation and industries (chemical, cements…) to significantly reduce their CO2 emissions. In the long term, it may also be a partial solution to the variability of renewable power sources.

Meet the safety and security challenges of hydrogen

For engineering projects working to support the hydrogen revolution, it is essential for safety to be at the very core. Whilst the challenges of hydrogen safety are not fundamentally new, the undeniable growth of this energy carrier will involve new requirements for industrial sectors that are already highly regulated, particularly in terms of process safety. The issue of hydrogen safety is central to accelerating the hydrogen revolution for the benefit and protection of our planet.

Develop storage and transport infrastructures for H2

For the hydrogen revolution to be a success, this energy carrier will need dedicated infrastructures to allow its transport and storage. These two prerequisites are essential to make all the uses of H2 possible in the years to come.


Assystem acts as architect engineer and one-stop shop, combining multiple disciplines and expertise: decarbonised electricity, infrastructures, complex systems, regulations, transportation… Those multiple areas of expertise allow Assystem to support private and public stakeholders on pilot projects, and on industrial applications in production, storage and distribution of hydrogen.

The massive development of low-carbon hydrogen is synonymous with a parallel expansion of the decarbonised energy sources needed to produce it. Our experience in successfully delivering complex projects for more than 50 years makes Assysteman exemplar to support development of clean energy sources:

  • Assystem is committed to the development of renewable energy
  • Assystem is ranked in the Top 2 international nuclear engineering companies worldwide
  • Assystem is adapting the architecture of electricity networks all over the world

Assystem offers an integrated cross-sector approach.  This enables us to support the delivery of complex projects/systems, effectively integrating energy conversion equipment and infrastructure.  Our H2 engineering service provides a methodology to assist stakeholders who want to get involved in the design, fabrication and commissioning of H2-based systems, and the safe operation of any H2 based installation. Acting as an Owner Engineer, Assystem provides end-to-end support for H2 projects.

Assystem can also count on its knowledge of H2 applications’ sectors (transportation, gas or chemical industry): at the high end of infrastructure development. Assystem offers solutions to support all kinds of industrial and process industry clients for construction programs, maintenance and operations, engineering design and systems integration.
