Researchers at Rice University have unveiled a breakthrough technique that dramatically extends the life of carbon capture devices using a simple acid vapor method. Traditional CO₂ electrolyzers clog over time due to salt buildup, but Rice’s team found that passing CO₂ gas through a mild acid dissolves these salts before they block the system. The result is a device that runs stably for over 4,500 hours — more than 50 times longer than standard systems. This innovation works across a range of catalyst materials and scales, without degrading performance. Unlike complex hardware fixes, this is a low-cost, elegant solution that addresses one of the biggest durability hurdles in carbon capture technology.

By simplifying maintenance and reducing downtime, the method significantly enhances commercial viability. As global efforts to decarbonize intensify, this discovery represents a crucial step toward practical, scalable carbon removal infrastructure.
