This Presentation on GBE:


Green or Violet Materials

  • Construction/Infrastructure/Rail
    • –Are energy, carbon and labour intensive
    • –to create and maintain
  • Imported materials:
    • –High Carbon: Cement, Concrete, precast,
    • –High Energy: Reinforcement, steel, copper, other metals
    • –Carbon Sequestration: growing aggregates: C8S
    • –Biogenic Carbon Sequestration: timber, bio-based materials
      • Revert to timber sleepers: durable Hardwood not treated softwood
    • –Fossil Carbon: Asphalt, bitumen (Some fossil carbon)
    • –Fossil Carbon: Plastics, hydro-carbons, petro-chemicals
    • –High Energy & Emissions: Rail joining chemistry
  • Heavy haulage and emissions: concrete, aggregates, soil, steel, green waste:
    • –via rail v road?
  • Labour Miles: rail v trucks v trucks on rails

Material choices

  • In particular OPC cement replacement in concrete (after water, concrete is the most used material)
    • –GGBS or PFA: low carbon, Slower set
    • –OPC & GGBS or PFA blended cements: normal setting forced on by OPC
  • Risks of product or material surreptitious substitution raising the carbon count
  • Robust specifications control substitution,
    • –Policing the specification is essential
      • Be Proactive about it
  • –Get it right first time

Energy and Carbon in Rail

  • Energy In use:
    • –Energy Efficiency in production
  • Steam generators: lost opportunity? revert to steam trains!
  • Dispersed production: Local to Rail lines, along rail lines: PVs (EU examples)
    • –Energy Efficiency in distribution: HV overhead or buried cable 11,000V radiation losses
    • –Energy Efficiency in consumption
      • Catenaries? Bottom Rails? 11,000V radiation losses
  • Embodied Energy
    • –Copper & catenaries, electrical power and communications cables,
    • –Steel: rails, signalling cables, steel tube piling
    • –Galvanized steel Catenary supports,
  • Embodied Carbon
    • –Cement, Concrete
    • –Fossil carbon: Plastics, Hydro carbons, natural Asphalt, natural Bitumen,
  • Sequestered Carbon
    • –Biogenic carbon calculations: few opportunities in rail? Acoustic fences in roads
    • –Not Fossil carbon
  • Growing aggregates (rounded: not ideal for concrete or rail support)

What New Rail Infrastructure?

  • Impact of road and rail transport in LCA
    • Flights are very carbon and energy inefficient
    • Ships are very efficient
    • Rail is very efficient
    • Road is worse
    • Big trucks are better than small vans
  • Role of consolidation centres
    • Long haul in big trucks or trains
    • Pallet services removes many small vehicles off road
      • Needs less drivers
    • Switch goods to smaller trucks in consolidation centres
      • Short haul in small trucks for easy access
