Low Cost Open-Path Instrument for Monitoring Surface Carbon Dioxide at Sequestration Sites

Large scale geological sequestration of CO2, needed to reduce the impact of this greenhouse gas, requires a low cost sensor that could address the following challenges: easy deployment over large area; low cost in terms of deployment and maintenance over large CO2 stream and reservior; must address the risk, safety, and economic considerations to the type of geological sequestration reservior; the field test plan for the sensor should be ready or close.Commercial Applications and other Benefits as described by the awardee: The proposed sensor could also address other interesting gases, e.g. CH4 and N2O. The ability to cover long distances and networking feature will find applications, such as pipeline safety monitoring, dump site and other sequestration site green house gas monitoring and verification, and also many pollution monitoring applications over large metro areas.
