Conversion of CO2 to Ethylene/Propylene

This September 2024 Cypris research brief surveys the current state of technologies converting CO2 into ethylene and propylene, drawing on recent patents, academic research, and company activity across electrocatalytic, biological, and mechanochemical conversion approaches. While the field shows significant innovation momentum — with companies like LanzaTech and Twelve advancing toward commercial-scale deployment — widespread commercialization remains constrained by high energy demands, catalyst degradation, and the complexity of scaling these processes industrially. The landscape is defined by a diverse toolkit of conversion mechanisms rather than a single dominant pathway, with TRL levels varying widely across players from early-stage academic research to near-commercial demonstration.
What You'll Find in the Report
Multiple conversion pathways are competing, not converging
From electrocatalysis and microbial fermentation to mechanochemical processes, researchers and companies are pursuing fundamentally different routes to produce ethylene and propylene from CO2. No single mechanism has emerged as the clear industrial standard, leaving the technology landscape genuinely open.

A handful of companies are pulling ahead on commercialization
LanzaTech's DOE-backed Project SECURE and Twelve's Opus™ Carbon Transformation System represent the most advanced commercialization efforts, with both approaching or already operating at industrial scale. The gap between these leaders and earlier-stage players is widening.

Energy and scalability remain the defining barriers to watch
Across nearly every approach reviewed, high renewable energy requirements and the challenge of maintaining catalyst performance at industrial volumes are the key bottlenecks. How these constraints are resolved will largely determine which technologies reach mainstream adoption first.
