Research and expertise

Tools for the techno-economic and environmental assessment of energy systems involving:

  • Life cycle assessment
  • Life cycle costing
  • Real options analysis
  • Expert elicitation

Analysed systems include: conventional nuclear power plants, small modular reactors, unconventional fossil fuels (e.g., oil sands by-product coke), and conventional fuels used in unconventional ways (e.g., coal for polygeneration of electricity, steam and hydrogen).
