WURTZ

The Power-to-X based Carbon Capture and Methanol Production for Wastewater Decarbonization

Background

The project showcases a sustainable route to convert CO₂ emissions into green methanol, supporting climate goals and circular carbon use. It integrates the CAPPOW CO₂ capture unit and an advanced methanol synthesis system into a compact, modular setup. CO₂ is captured from flue gas at Vandcenter Syd’s wastewater plant and tested under real conditions to optimize performance.

Key partner TORM, a global shipping company, is exploring green methanol as marine fuel, supporting emission cuts both on land and in maritime transport.

Objectives

• Develop a robust catalytic process to convert CO₂ and H2 into methanol, tolerant to gas variations and impurities.
• Purify gases from the CAPPOW system to meet methanol synthesis requirements.
• Implement and operate a pilot system converting CO₂ from flue gas into green methanol at Vandcenter Syd.
• Perform in-depth quality evaluations of produced to verify its potential as a marine-grade fuel.

Expected results/impact

The project merges two innovative technologies to produce green methanol, offering a modular solution for small- and mid-scale CO₂ emitters.

Demonstrates methanol production from biogenic CO₂ at a decentralized wastewater plant.
Validate a compact CO₂ capture and conversion unit (CAPPOW + GTL).
Compatibility of produced methanol with maritime fuel standards.
Reliable operation under real flue gas conditions, including gas conditioning and catalyst performance.

This scalable approach for CO₂ emissions conversion into green fuels, aiding decarbonization in shipping sectors and lower the carbon footprint. The successful demonstration boosts Denmark’s role in green fuel innovation.
