NODE READINESS CATEGORIES

Each capability represents a resource node—a combination of a tool, technique, and expertise—that is unique to the national laboratory system. Each resource node is assigned a node readiness category that describes the readiness of the capability node for use in the water splitting pathway listed.

Category 1: the node is fully developed and has been used for research projects in the pathway listed.
Category 2: the node will require some development for the pathway listed. An example is a computational model that has been developed for one pathway but will require R&D to be adapted to another pathway.
Category 3: the node requires significant development for the pathway listed. An example is a characterization technique that has been developed for fuel cells but that requires significant R&D to be adapted for hydrogen production research.
