In london, buses are a massive source of particulate and nitrogen pollution.
We've had hybrid buses for a good 5 years, some hydrogen ones as well (but only one or two routes)
However london has rolled out 100% electric buses in the last 3 years, and they've not caught fire at a faster rate than the diesel ones.
Worry about them being electric later, the environmental impact of less people driving far overshadows the impact of ev vs gas busses.
Looking at another aspect, how many hydrogen generation facilities are there in CT, vs. facilities that can charge an electric bus?
One would also wonder why China has ~0 fuel cell buses and tens of thousands of electric buses if FC is the more mature tech.
Have they bought any recently? Have neighboring towns bought in as well?
> We will be running hydrogen and battery electric vehicles in identical service to collect real-world performance data for comparison—and to determine which technology performs better to meet the needs of our service as we move towards a complete zero-emission fleet by 2040.
It looks like they started the hydrogen bus project 20 years ago, not ten.
If you absolutely insist on having buses that aren't direct sources of CO2, fuel cells are a more mature technology that makes more sense than batteries.
