ChaRM: Optimising bus fleet decarbonisation
ChaRM by Ricardo
Calculate the most cost-effective approach to introducing a zero-emission bus fleet to your network.
Introducing ChaRM
Transitioning to a zero-emission vehicle fleet involves complex questions for fleet owners, operators and local government:
- What zero-emission technologies are suitable?
- What is the total cost of replacing fossil-fuel vehicles with zero-emission?
- What is the most cost-effective technology for my network?
- Which routes should be switched to zero-emission first?
- What infrastructure is needed and where should it be placed?
Ricardo's ChaRM provides specialist analysis and insight to remove the complexity and provide an informed route forward.
How it works
ChaRM modelling can use open access data such as General Transit Feed Specification (GTFS) and the locations of existing depot infrastructure to analyse all routes against three zero-emission options:
- Electric buses charging only at depot
- Electric buses charging at depot and opportunity chargers
- Hydrogen buses
Outputs:
- Total Cost of Ownership to replace existing bus fleet
- Recommended fleet composition e.g number of electric buses and/or hydrogen buses (including suggested battery size)
- Optimal location of charge points
Route level outputs
- Technology assignment
- Total Cost of Ownership at route level
- Energy delivered per chargepoint
- Optimal chargepoint numbers at identified locations
- Routes served by each chargepoint
Network level outputs
- Optimal mix of zero-emission technologies
- On-board energy requirements
- Total fuelling / chargepoints required and investment costs
- Total Cost of Ownership at route level
- Full lifecycle emissions for each strategy
