Technology Marketing Summary

This series of inventions addresses harsh environment sensing at temperatures above approximately 400-500oC using novel sensing materials that are compatible with optical sensing platforms as well as more conventional resistive platforms. The sensors will use thin films of specialized materials that can be integrated with optical platforms for measurements of chemical composition or other process properties in extreme conditions. An emphasis is currently being placed on development of sensing materials for hydrogen and carbon monoxide detection, but sensors can be potentially designed to measure other gaseous components including oxygen, carbon dioxide, steam, sulfur species and nitrogen species as well as others at high temperatures in energy systems and other applications

Description

The availability of fossil fuels to provide clean, affordable energy is essential for domestic and global prosperity and security well into the 21st century. Technologies now under development can make future fossil-fuel-based energy systems dramatically more efficient and cleaner than today’s plants, while helping to keep the cost of energy affordable. Innovative control systems can improve efficiency and reduce emissions in advanced fossil-fueled plants, but require novel sensors to measure gas compositions and other conditions inside the processes (embedded sensors) that can operate reliably for long times at high temperatures and in harsh conditions. Optical sensors use light to remotely access internal processes located in harsh environments rather than electrical connections or components.

Benefits

New, robust and reliable sensors can enable the highly automated process controls that are needed to optimize the operation and performance of advanced fossil fuel based energy systems.

Applications and Industries

Harsh environment sensing in energy applications such as gas composition in gasification, oxy-fuel combustion, natural gas processing, fuel cells, gas turbines, and other energy conversion systems.

The types of materials currently under development could also be utilized for sensing in environments with similar temperatures and harsh conditions relevant to defense, space science, or industrial manufacturing process monitoring and control.
