Low-carbon Hydrogen

Best integrated technology solution for low-carbon hydrogen

Achieving large-scale, low-carbon hydrogen production requires the seamless integration of multiple core technologies. Air Liquide provides a differentiated, low-carbon technology approach. By integrating the Lurgi™ Autothermal Reformer (ATR), Cryocap™ H₂, and Air Separation (ASU), we create a highly optimized process.

Our advanced carbon capture technology, capable of capturing over 99% of direct CO₂ emissions, enables maximized hydrogen yield with minimum carbon intensity. Furthermore, the process is designed so that the captured CO₂ is readily available in different forms (gas, liquid, or supercritical), making it fully ready for utilization and storage with minimal cost variation.

The benefits of our integrated approach

Our ATR + Cryocap™ H₂ + ASU architecture delivers three primary advantages for large-scale decarbonization projects:

• Lowest cost of production: We utilize internal combustion in the ATR, with oxygen replacing the need for additional fuel and complex flue gas treatment.
• Lowest capital investment: Utilizing a single ATR reactor serves as a highly efficient alternative to multi-train Steam Methane Reformers. Additionally, the system allows for the maximum possible modularization for the ASU, as well as a higher scope for modularization for Cryocap™ H₂ when compared to alternative capture technologies.
• Minimum carbon intensity: The system guarantees a direct CO₂ capture rate of more than 99% due to minimum carbon loss. It ensures maximum H₂ yield, leading to minimum Scope 3 emissions from the supplied feedstock, and offers integration potential with renewable electricity to further minimize overall carbon intensity.
