Surveilling carbon sequestration: A smart collar to sense leaks December 13, 2022 9:00 am Published by Admin Sandia National Laboratories engineers are working on a device that would help ensure captured carbon dioxide stays deep underground — a critical component of carbon sequestration as part of a climate solution.

(Animation by Max Schwaber) Carbon sequestration is the process of capturing CO2 — a greenhouse gas that traps heat in the Earth’s atmosphere — from the air or where it is produced and storing it underground. However, there are some technical challenges with carbon sequestration, including making sure that the CO2 remains underground long term. Sandia’s wireless device pairs with tiny sensors to monitor for CO2 leaks and tell above-ground operators if one happens — and it lasts for decades. “The world is trying a whole lot of different ways to reduce the production of CO2 to mitigate climate change,” said Andrew Wright, Sandia electrical engineer and project lead. “A complementary approach is to reduce the high levels of CO2 in the atmosphere by collecting a good chunk of it and storing it deep underground. The technology we’re developing with the University of Texas at Austin aims to determine whether the CO2 stays down there. What is special about this technology is that we’ll be monitoring it wirelessly and thus won’t create another potential path for leakage like a wire or fiber.” Learn more about the work in the complete press release.
