Scientists turn captured CO2 into valuable industrial chemical
Scientists convert CO2 into ethylene, a valuable chemical, with high efficiency and stability.
Why it matters
- Offers a path to profitable carbon recycling by converting CO2 into ethylene.
By the numbers
- 85% Faradaic efficiency.
- 750 mA cm−2 partial current density.
- Stable electrolysis for over 1,500 hours at 600 mA cm−2.
The big picture
- Could make CO2 capture profitable by converting it into ethylene.
- Uses high-pressure membrane electrode assembly with In/Cu catalysts.
What they're saying
- Concerns about energy requirements and market implications.
- Mentions of thermodynamics challenges.
Caveats
- Process might face challenges in scaling up.
- Energy requirements are a concern.
What’s next
- Potential to minimize energy consumption by avoiding CO2 depressurizing and repressurizing.
