Overview
CETH2 is a company specializing in the development, manufacturing, and sale of innovative, CO2-free hydrogen generation solutions for industrial and energy applications. The company is part of a European family-owned group with over 20 years of investment in renewable energies and more than 10 years of expertise in hydrogen systems management.

Hydrogen Production Technologies

• Electrolysis: CETH2 uses Solid Polymer Electrolyte (SPE) or Proton Exchange Membrane (PEM) electrolysers to convert electrical energy into chemical energy stored in hydrogen. The process involves the breakdown of water into hydrogen and oxygen, with hydrogen being produced at the cathode.
• Reformers: The company also focuses on catalytic steam reforming of bioethanol and methanol, with a product line capable of producing up to 10 Nm3/h of hydrogen.

Hydrogen Purification
CETH2 employs Composite Metal Membrane (CMM) technology for hydrogen purification, achieving ultra-pure hydrogen with a purity of 99.99999% and a capacity of up to 1 Nm3/h. The technology is noted for its high resistance to thermal cycling.

Product Lines

• PEM Electrolysers: The product line ranges from 5 to 60 Nm3/h, with modular options allowing for coupling up to 720 Nm3/h or 3.6 MW.
• Membrane Catalyst Reactor: Designed for the direct conversion of methanol into pure hydrogen suitable for PEMFC applications, with capacities ranging from 1 to 5 kW.

Compliance and Standards
CETH products comply with various European directives, including machine guidelines, pressure equipment, explosive atmosphere, low voltage, and electromagnetic compatibility guidelines.

Research and Development
CETH2 is involved in research projects such as high-pressure PEM electrolysers and CO2 electrochemical reduction. Their research activities are eligible for the French research tax credit (CIR).

Services
The company offers project management, on-site construction management, consulting, project assistance, feasibility studies, and contract management. They also focus on system integration of hydrogen solutions and demonstration project development, including hydrogen mobility and renewable energy storage.
