Then you have the energy waste of hydrogen which most people have written about.

They have signs outside every enclosed or tunnel bus way explaining this so no bus operator ever accidentally runs a CNG bus there. Now a hydrogen bus has a tank pressure of more than double a CNG bus. Most people focus on the combustion risk but that's not really the issue.

I only compared battery bus to trolley bus. I didn't get into hydrogen. Short story: We already can't run CNG buses into a lot of bus ways (ex. Harvard) in Boston because of the tank pressures (250 bar) being so high that a tank rupture happens the ensuing explosion would level the building.

This dude was a keynote speaker at the 2025 Abundance conference, along with Ezra Klein, Derek Thompson, and a host of other Abundance-aligned folks.

Heterodox thinking indeed.
The Abundance crowd LOVES masked agents kidnapping delivery drivers and snatching children away from their families

I have literally traveled the country researching this and talking to experts.

They have a lot of other drawbacks besides the loss of range in the cold. I made a whole video about it and I have been fighting to have the T bring back the trolley bus network since 2019. Fuel cell has issues with more than price, example tank pressure safety issues.

lol. I never had any in the first place.

Joshua Miller in the Boston Globe's "Camberville and Beyond" ran a story on Jan 22 2026 talking about the battery school buses purchased in past years have failed.
I have to ask:
Has anyone tested this product?
What were the results of the accelerated age testing?
Do they still use diesel heaters?

January 22 2026 the story ran showing that these things are a dud if you don't believe me.

The problem is:
1. The buses don't actually work
2. The proponents don't understand a school bus isn't just an electric car but bigger there are serious unsolved design issues
3. They produce a lot of microplastic because of the battery weight & at least in the northeast have a diesel heater onboard

The difference between Poftak/Baker vs Eng/Healey (@massgovernor.bsky.social).

Baker's constant attempts to privatize the T fragmented everything. Ex: Hynes station brightening used multiple scaffolding's to do each step of cleaning, leak "fixing" & painting.
VS
Now it's one small team sharing.

So yes it did take from 2021 to now but it's important to understand that this is an example of how an integrated internal engineering team can do things quickly and as a side effect more cheaply too. So we should see this accelerate. Slide from the board presentation.
