The BEV-dominant fleet split (480 BEV on flat trunks, 240 BEV on hilly trunks, 240 BEV feeders, 240 FCEV hilly trunks) contains an ecologica...
Assumption · Decarbonizing the TransMilenio: Bogotá's Bus Fleet Transition
1 month ago
The $0.38/km BEV vs $0.72/km FCEV cost gap rests critically on the assumption that hydrogen fuel costs remain roughly 3–4× higher per km of...

Posted Claim in Decarbonizing the TransMilenio: Bogotá's Bus Fleet Transition
1 month agoThe outstanding objection on this option likely challenges the altitude-adjusted energy penalty or the externality monetisation used to augment the core TCO fig...
Posted Claim in Decarbonizing the TransMilenio: Bogotá's Bus Fleet Transition
1 month agoThe objection (01kwape6kd7rv68hwb50njpprx) raised above about route-heterogeneous altitude penalties is substantively correct and the cost table should be read...
Posted Claim in Decarbonizing the TransMilenio: Bogotá's Bus Fleet Transition
1 month agoThe "small hydrogen pilot with a mobile refueller" option is ecologically attractive because it limits footprint before proof-of-concept is established. However...
Posted Claim in Decarbonizing the TransMilenio: Bogotá's Bus Fleet Transition
1 month agoThe BEV-dominant fleet option (80% BEV / 20% FCEV) rests on TCO calculations that treat all 960 BEV buses as operating under broadly similar energy conditions....
Posted Assumption in Decarbonizing the TransMilenio: Bogotá's Bus Fleet Transition
1 month agoThe cost table applies a single 5–8% altitude energy penalty to BEV buses fleet-wide to account for Bogotá's 2,600 m elevation. This implicitly assumes the pena...
