Assessing the dynamic material criticality of infrastructure transitions: A case of low carbon electricity.

Highlights: [•] We present a method to analyse material criticality of infrastructure transitions. [•] Criticality is defined as the potential for, and exposure to, supply disruption. [•] Our method is dynamic reducing the probability of lock-in to at-risk technologies. [•] We show that supply disruption potential is reducing but exposure is increasing. [ABSTRACT FROM AUTHOR]
