CO2 Catalysts

CO2 Methanation Catalysts through Plasma Catalysis or Thermal Catalysis

Background

In response to the urgent global imperative to reduce greenhouse gas emissions, industries are actively seeking innovative methods to transform CO₂ into valuable resources. One promising avenue is the methanation of carbon dioxide, which enables the conversion of captured CO₂ into renewable methane or methanol. This approach not only supports the decarbonisation of industrial processes but also enhances the valorization of carbon streams.

Technology Overview

We have developed a novel synthesis process for mixed oxides, enabling the production of highly porous and efficient catalysts specifically engineered for CO₂ methanation. Leveraging a hydrotalcite structure optimised through the incorporation of a surfactant, these catalysts exhibit a substantial specific surface area (up to 178 m²/g) and meticulously controlled porosity. This design ensures superior catalytic yields and enhanced stability under industrial operating conditions.

Stage of Development

The technology has demonstrated robust performance in laboratory, with key performance indicators.

The product is ready for further scale-up and commercial deployment.

Benefits

• Exceptionnal performance: Achieves CO₂ conversion rates of up to 90% in both thermal and plasma-assisted methanation reactions.
• High selectivity: Delivers methane selectivity exceeding 98% under optimal conditions.
• Enhanced durability: The mesoporous architecture and regulated basicity significantly reduce coke formation, thereby prolonging catalyst stability and operational lifespan.

Applications

• Power-to-Gas systems for renewable energy storage and grid balancing
• Production of renewable methane or methanol from captured CO₂
• Decarbonisation of industrial gas streams

Opportunity

This innovative catalyst technology presents a compelling opportunity for industrial partners seeking to advance sustainable energy solutions and meet stringent emissions targets.
