Embedding new low CO

technology
introduces
critical materials
into
infrastructure:
•
!
e.g. N
Ndd - motors/generators for wind
turbines & electric vehicles
•
!
Not just elements: e.g. aggregates
•
!
Scale of infrastructure means that change
in demand can be a
step-change
::
Multiples, not fractions
•
!
Previously abundant materials
may
become critical

PURPOSE:"
"understand the stocks and flows of materials in
infrastructure."
"
OUTCOME:"
"Identify where/when supply risks appear and what
interventions can mitigate against them. "
"
!
Three key features:"
"1. Infrastructure "
"
"
focused on the scale and complex technological basis of
"
infrastructure.
"
"2. Dynamic "
"
"
to enable a dynamic assessment of criticality.
"
"
3. Hierarchical!
!
!
to allow analysis of recovery and substitution of materials and
"
technologies.
