Enzymatically active high-flux selectively gas-permeable membranes for enhanced oil recovery and carbon capture

A membrane structure for moving a gaseous object species from a first region having an object species first concentration, through the membrane structure, to a second region having an object species second concentration different from the first concentration is described. The membrane includes a supporting substrate having a plurality of pores therethrough, each of the plurality of pores defined by a first end, a second end and a surface of the supporting substrate extending between the first end and the second end as well as a nanoporous layer within the plurality of pores, wherein the nanoporous layer comprises a hydrophilic layer and a hydrophobic layer. The membrane also includes a liquid transport medium within the hydrophilic layer. The liquid transport medium includes a liquideous permeation medium and at least one enzyme within the liquideous permeation medium. The at least one enzyme is reinforced by at least one stabilizing component.

Carbon Capture, Utilization, & Storage (CCUS) in Achieving a Net Zero Emissions Future - System Cost of Replacement Energy (SCoRE): A Tool for Assessing Technology Substitution Pathways to Decarbonization

This presentation outlines the SCoRE tool, which can be used to identify the least-cost technology substitution pathway to meeting a decarbonization target within an operating region of the United States. The presentation showcases results from an application of the tool in the ERCOT operating region.
