US scientists use plasma and electricity to turn CO2 into sustainable jet fuel

illuminem summarises for you the essential news of the day, reviewed by our editorial team. Read the full piece on Interesting Engineering or enjoy below:

🗞️ Driving the news: Yale researchers have developed a plasma-electrocatalysis system that uses electricity to convert CO₂ into chemicals including methanol, butane and other multi-carbon products that could serve as precursors for sustainable aviation fuel
• The process operates at room temperature and atmospheric pressure

🔭 The context: The technology combines plasma, which activates CO₂ molecules, with a copper-based electrocatalyst
• The researchers designed a three-phase gas-liquid-solid interface to prevent water from neutralising reactive plasma species before they reach the catalyst

🌍 Why it matters for the planet: If powered by renewable electricity, the process could provide a route to produce fuels and chemicals from captured CO₂ while reducing reliance on fossil-based feedstocks
• However, the reported results are at the research stage, and their full climate benefit will depend on factors including energy efficiency, CO₂ sourcing and eventual scale-up

⏭️ What’s next: The Yale team plans to optimise the catalyst and test alternative materials
• The researchers also say the system can operate with intermittent renewable power, potentially supporting more flexible deployment

💬 One quote: “You can switch it on or shut it off at will based on when electricity is available.” — Lea Winter, Yale University
