As transit agencies move away from fossil fuels, they are figuring out which environmentally friendly option is right for them.
Public transit agencies are often among the first customers for vehicles that run on new types of fuel, whether it was cleaner-burning diesel in the 1990s or natural gas more recently.
Today, eco-conscious agencies looking to switch to electric fleets face a big choice: power them with rechargeable batteries or with hydrogen fuel cells?
There isn’t an obvious answer. Both are more environmentally friendly than fossil-fuel buses, and both can be cost-effective options.
