Embedded Gas and Temperature Sensors for Extreme Environments - U.S. Patent Pending

Scientists at NETL have developed optical sensor materials suitable for the high temperatures associated with coal gasification, solid oxide fuel cells, gas turbines, boilers, and oxy-fuel combustion systems. Not only can these advanced sensors withstand temperatures approaching 1,000 °C, but they are simple to fabricate, and they provide sensing responses across a broad range of wavelengths. Because of the sensors’ simplicity and durability, they overcome limitations of sensors currently on the market. More

Thin Ionic Liquid Film Deposition within Porous Substrates - U.S. Patent Pending

NETL inventors have solved the problem of using ionic liquids in membrane functions by creating a method for depositing thin liquid layers within the pores of a thick porous substrate. The method creates the equivalent for a commercially viable asymmetric membrane, but with a liquid, rather than a solid, active layer. In doing so, the new technique makes many classes of supported liquid membranes, including supported ionic liquid membranes, practical for gas separations. More

Variable Grid Method for Visualizing Uncertainty Associated with Spatial Data – U.S. Patent Pending

To accept the challenge of accurately portraying uncertainty associated with a given spatial dataset and the related products, scientists at NETL have created an approach called the Variable Grid Method that allows decision makers such as managers, researchers, and industry users to accurately identify spatial patterns and trends, as well as the uncertainty associated with the data and subsequent interpretation.

Hybrid Process for Post-Combustion CO2 Capture – U.S. Patent Pending

In response to cost concerns associated with post-combustion CO2 capture, scientists at NETL have developed a hybrid process using a solvent-based absorption/high pressure stripping gas step coupled with selective CO2 membrane separation, integrating the most efficient aspects of each method. The method is unique in that the solvent-based absorption/stripping process uses thermal compression to efficiently increase the concentration and partial pressure of CO2 in the gas mixture, allowing for more efficient membrane separation.
