Green CO₂ to Green Methanol: A Circular Economy Breakthrough

Conference Presentation
David Surplus OBE's presentation at the Phoenix Renewable Gas Conference 2025 highlighted how green CO₂ captured from Anaerobic Digestion projects can be used as a feedstock to synthesise green methanol, creating a true circular economy solution.
Key Benefits
Sustainable Fuel Production: Green methanol serves as a zero-emission fuel for hard-to-decarbonise sectors such as maritime transport and industrial applications, providing a practical alternative where direct electrification is challenging.
Economic Value Creation: Transforming CO₂ from AD projects into green methanol creates new revenue streams for anaerobic digestion facilities, enhancing the economic viability of renewable energy infrastructure.
Grid Decarbonisation: This approach supports the decarbonisation of the gas grid by providing renewable alternatives to traditional natural gas, contributing to broader energy transition goals.
Resource Utilisation: The process enables better utilisation of resources from AD operations, including the potential for nutrient recovery and sustainable agricultural applications.
How It Works
The circular economy process involves several key steps:
-
Anaerobic Digestion: Organic waste is processed through AD systems, producing biogas and capturing green CO₂ as a byproduct.
-
CO₂ Capture and Purification: The green CO₂ is captured and purified to meet the specifications required for methanol synthesis.
-
Green Hydrogen Production: Renewable electricity powers electrolysis to produce green hydrogen.
-
Methanol Synthesis: The captured CO₂ is combined with green hydrogen to synthesise green methanol through Power-to-X technology.
-
Fuel Application: The green methanol serves as a sustainable fuel for shipping, power generation, and other industrial applications.
