Hyvolution & Gas Analysis: ENGIE at the heart of metrology and gas quality issues

Can you tell us a bit about this event? 

The Gas Analysis conference will be held in January 2026 in Paris, alongside the Hyvolution trade show. This proximity creates interesting synergies between the two events.

Gas Analysis focuses on the scientific and industrial challenges of gas analysis:

• What innovative solutions are emerging from  academia and industry?
• How can we build knowledge and skills in this strategic area?

It’s a state-of-the-art meeting where researchers and industry leaders come together to bridge the gap between fundamental research and operational challenges. For ENGIE, it’s an opportunity to draw inspiration from scientific advances and anticipate solutions that will meet the practical challenges of future  hydrogen projects.

Why is the presence of ENGIE and Lab Crigen essential?

Our participation in Gas Analysis allows us to:

• Engage with suppliers and steer their developments in line with our constraints in the field.
• Strengthen our visibility and our legitimacy within the ecosystem.
• Support the structuring of the sector, from research to operational projects.

We are also developing a range of gas quality analysis services (sampling, analysis, training and expertise). Demonstrating our expertise and commitment to quality, is crucial, in a context where the normative framework is still under construction.

Can you define metrology for our readers?

Metrology is the basis of plant operations. In hydrogen projects, it is based on two aspects:

• Gas composition: its “identity card”.
• Quantity delivered.

It also covers measurement methods and their control. In a context where standards are not yet stabilised, metrology has a direct impact on the performance, reliability and profitability of installations. ENGIE is raising awareness and actively contributing to standards committees and European projects to secure these practices.

During Gas Analysis, you’ll be involved in a few things. Can you tell us more?

Yes, at this show, I will be presenting the results of an unprecedented European project:

• Objective: Compare different hydrogen sampling systems to guarantee the reliability of analysis results. 
• Method: Inter-laboratory tests with several European partners, using a common protocol and centralised analyses.

This study highlights the importance of choosing appropriate equipment and adopting best practices to prevent any sample deterioration.

I will also chair a session on new gases and energy use (CO₂, hydrogen, biogas).

Additionally, Emeline Moreira from Lab Crigen will speak about measuring water, oxygen and nitrogen in hydrogen, a key issue for the industry given the high probability of their presence in sampled gas.

What can you tell us about the hydrogen sector today? 

The industry’s structure is still taking shape. ISO and EN standards are gradually evolving, driven by European projects and collective awareness. The ISO mobility standard was reviewed this year, and a new EN version is expected in 2026. There is strong momentum: projects are moving forward, and hydrogen quality is becoming a major concern.
