On November 28, 2025, the VZDI and its partners inaugurated the first industrial-scale methane pyrolysis plant at the site of V-ZUG in Zug, Switzerland — a landmark moment for industrial Power-to-X applications. 

What is Methane Pyrolysis and Why It Matters

Methane pyrolysis is a process that uses a microwave-generated plasma to split methane (CH₄) into hydrogen (H₂) and solid carbon (C), without emitting CO₂. 

The hydrogen produced can serve as a clean, high-energy fuel for industrial processes.  The solid carbon does not become a greenhouse gas; instead, it becomes a potentially valuable raw material — for example for building materials, asphalt, soil improvement or other industrial uses. 

This aligns with the broader concept of Power-to-X: using methane as a carrier to produce hydrogen (the “X” being H₂ or other derivatives) while avoiding CO₂ emissions, and ideally creating a circular carbon economy.

Key Facts of the Pilot Plant

The plant delivers up to 10 kg of hydrogen per hour 22 tons per year with a purity between 95–99%.  It is estimated to reduce about 240 tonnes of CO₂ per year compared to using conventional fossil natural gas.  The produced carbon is being assessed for reuse in construction materials, agriculture or other applications.  The initiative brings together 16 industry partners, research institute Empa, and support from the Canton of Zug — a powerful example of public-private collaboration. 

Significance for Power-to-X and Industrial Decarbonisation

This project demonstrates how Power-to-X concepts can go beyond lab scale and become industrial reality. By combining pyrolytic hydrogen production with reuse of solid carbon, the approach addresses two key challenges: reducing CO₂ emissions and creating a circular carbon loop.

For industrial high-temperature processes — like enamelling ovens, steel, cement or other energy-intensive manufacturing — the availability of hydrogen as a clean fuel is a game changer. In this sense, the V-ZUG plant is not only a technical milestone but a model for further scaling across industries.

Moreover, if the methane input is renewable (e.g. synthetic methane produced from renewable hydrogen + captured CO₂), the net effect could even become negative emissions — turning the carbon content into a long-term carbon sink. 

Outlook

The pilot plant is a first step. The ambition, as stated by VZDI, is to build a global, economically self-sustaining ecosystem for emission-free methane use and hydrogen supply. 

For stakeholders in energy, industry, and climate policy — including actors like us at SPIN interested in eSAF, synthetic fuels and sustainable energy systems — this project underscores the potential of methane pyrolysis as a bridging technology: delivering hydrogen today, enabling circular carbon use, and paving the way toward negative-emission industrial systems.
