Electric buses are all the buzz. But RTS thinks hydrogen might be better for Rochester winters
...The public transit authority has found that Rochesters climate particularly its long winters limit the range an electric bus can travel on a single charge. RTS has operated 10 electric buses through the past two winters.
They've operated well, RTS chief executive Bill Carpenter said, but estimates the range drops by about 30 miles on hot days, and 100 miles on cold ones.
The result is that, in winter, an electric bus cant be run on about 70 percent of RTS routes because the routes are too long, officials said. The battery is less efficiently in temperature extremes, he said, and the AC and heater takes a lot of energy.
So they have ordered electric buses with bigger batteries. And with the $5 million, they will buy two full-sized hydrogen fuel cell buses, a few smaller ones and a fueling system...more

(775 posts)Gaseous hydrogen in a bus or a car is NOT a bomb
Proof:
The use of explosive gas is nothing new in the US or anywhere else
Look into the history of that blimp- do you know what the actual skin of that ship was made of?
Also, around 2/3rds of the passengers and crew survived.

(33,523 posts)...hydrogen is made.
It's slightly less dangerous than hydrogen and requires no new infrastructure.
There are compressed natural gas buses and trucks all over the world. They're cleaner, because they don't waste energy,.

(775 posts)There are very few people in today's H2 industry that promote black or brown hydrogen
But you're not going to get this, so hopefully we can agree to disagree.

(33,523 posts)That would be one in which people were required to know the laws of thermodynamics before graduating high school.
The so called "renewable energy" fantasy has been coming out of crystal balls for my entire adult life.
It would be OK if I were a credulous kid in a world not already bleeding to death because people engage in idiotic faith, but I'm an old man.
In my life time, the concentration of the dangerous fossil fuel waste carbon dioxide in the atmosphere rose by close to 100 ppm with the same stupid chant about so called "renewable energy" saving the world the whole damned time.
This ad appeared in 1954:
Every dime spent on this nonsense comes out of the flesh of future generations. This reality has never stopped people from chanting the same nonsense about "solar hydrogen" or "wind based hydrogen." The fact is that wind and solar after trillions of dollars squandered on them can't even replace dangerous natural gas nor coal, never mind petroleum.
People who say otherwise should open a newspaper, or gasp, a scientific publication, but they won't. They'll just watch cartoons and confuse them with reality.

(1,091 posts)Anytime you burn a fossil fuel you waste energy, mainly in the form of heat.
Using electricity from windfarms to make Hydrogen at a time when they basically give it away because it's at a time of low demand, while inefficient, is better than throwing it away.

(33,523 posts)They spew it all the time, but have difficulty recognizing it as such.
They also know next to nothing about the laws of thermodyamics, and have zero knowledge of industrial processes.
I posted reference to a recent scientific publication that reported, as of 2021, world sources of hydrogen. As it involved a scientific publication, it almost certainly went over the head of the wishful thinking antinuke "wind will save us" community, but it showed increasing reliance on coal.
The thermodynamic nightmare of electrolysis remains, after half a century of delusional hype, a trivial source of the gas. It accounts for about 4% of world hydrogen with no information connected to the source of already thermodyamically degraded electricity, although it remains a fact that the majority of electricity on this planet is generated by burning dangerous fossil fuel, this after half a century of so called "renewable hydrogen" talk.
Anyone with a shred of technical insight would be cognizant of the energy cost of the liquefaction of hydrogen which is a well known fact that has been discussed over the decades of that this absurd hydra has been flying around with no result other than the acceleration of climate change.
Facts matter.
