Roads2HyCom is developing an analytical methodology to understand the state of the art of technology relative to the infrastructures and resources that will support it, and the early-adopter communities that will use it. The methodology is based on eleven categories of “metric” which are used to profile each technology.

The 11 metric categories are:

			Global environmental impacts				Capacity & Performance
			Local environmental impacts				Societal & Political Acceptance
			Energy Efficiency				Availability / Accessibility
			Energy Supply and Security				Potential for Growth
			Life Costs				Safety & Risk
			Environmental Impacts

The State of the Art in each technology area can be given a rating against these metrics (and sub-metrics in each category) to create a “profile”. For the technology to find acceptance with users, that profile has to attain certain thresholds, either in absolute terms or relative to some benchmark.

The nature of infrastructures and resources, and the needs and capabilities of early-adopting communities, have an influence on the level of these thresholds. This is the basis of the Roads2HyCom analytical methodology.
