Hybrid school bus, is it possible?

Hi, I was just throwing this out there. Of course I'm going to convert my bus first. But. Is it possible to replace and rewire the engine to make the bus a hybrid, and if so how. If you can id like a ballpark on how much it'd cost. I'm really new at this and want to make my bus eco friendly because I feel bad driving a Diesel engine. So if you could help me out with that I'd appreciate it!

Thank you very much!

Anything is possible with enough money. I've never done this kind of conversion but I'm betting it's very expensive.
Why do you feel bad driving a diesel? ? ? They are more efficient for power than a big gas engine. If it's blowing smoke than something is wrong with it? I have a 1968 2 stroke diesel engine in my bus that is built on technology from the 50's, granted it was rebuilt about 10k miles ago, but it doesn't smoke at all! These trucks you see with "got smoke? " stickers and bellowing black smoke have an engine that is NOT set up correctly and shouldn't be blowing smoke!
I'm all for taking care of our environment but at what cost? ? How far ahead are states like California that is forcing people to destroy working vehicles just because they put out like 10% more emissions than newer cars just to fill up the land fills?
Example ; say you convert yours to a hybrid.... What are you going to do with the old parts? What about the power and resources to make the new parts you need and the hazardous battery bank? Batteries last less when used in such high demand do they need to be replaced more often, more waste. Then you have the resources such as electricity, welding materials, waste products and etc for doing the conversion.

Sorry, I'll get off my soap box. This was absolutely not towards you! I don't know you? Sounds like you have good intensions. I'm frustrated with the subject of climate change not you.
I do think a hybrid would be pretty cool. I thought about designing one as a rock crawler once.

One thing to keep in mind is fuel driven hp is NOT the same as electronically driven hp. I don't have exact equation but it's something like half or less. Meaning a 300hp engine could be replaced by a 150hp electric motor.i don't know why.

Thanks! I was just wondering if it was a good idea and I sure have my answer now XD. The cost is probably to much for me anyways. I was just wondering possible alternatives, I hadn't researched quite as much as I should have.

As an example, one of the city bus companies was selling a bunch of hybrid bus parts on GovLiquidation. I'd never seen that before. The parts were all sold in lots of 10, so it was above the average man to purchase those parts. I would like to have 10 bus sized battery packs. Point is if a bus company couldn't make it work and sold off the parts, what chance do we have?

Someone did an electric semi tractor once (I'll chase down the ref if anyone is interested) but it was clearly a 'how silly!' conversion: the battery pack would nearly exceed your vehicle rating. Hybrids would be better than straight electric (smaller pack) but then you would need a gas or diesel engine TOO...

Electric HP gets more done because they develop 100% torque from a standstill, which is not the way IC engines behave. 'Course you need wires the size of a horse's leg.

Assuage your green conscience by reminding yourself that you are doing one heck of a repurposing.

our city locality bought 20 Gillig Hybrid Busses 10 years ago... today they only have 2... a friend of mine that drives for the city transit says those busses were a lot of trouble...

the current consensus on clean energy is running COmpressed Natural Gas... my city is running I think he said 80% CNG busses now and they are very reliable... of course those busses are easy to spot as the very large tanks are on the roof...

when asked why the tabks werent in the basement area... it was stated because of safety... a Bus is Much more likely to be struck in the side by a car or truck than it is to flip... CNG is something to consider as the engines are very similar to a standard diesel with just a different fuel delivery system.. as least thats how he explained it to me.. and also how it looked when he showed me under the rear bonnet of his route bus...

when I had my chevy volt that was one of the really neat things about it.. was that it produced maximum torque very quickly off the line... from the factory there was a delay built in to "simulate more standard cars"... but once we got into it's computer and removed that part of the program... woooeeee that chevy volt would slam your head back pulling into traffic in all electric mode..

Re CNG: be sure there are refueling facilities where you will be. I was dismayed to find a cheap CNG bus but no way to refuel it as I drove it across country or in Idaho where I wish to relocate.

Cincinnati has some hybrid buses, they cost about $150,000 more than a normal bus, the estimates are that they will save a whole $8000 in fuel over their life span, not worth the effort

another company is rebuilding old transit buses as electric buses and they cost about the same as a new transit bus and have about a 120 mile range, so good for an 8 hour shift in most cities, I think we will see many of these in the future

Huh - maybe my response was premature. But I'm guessing the battery costs would dampen one's enthusiasm: a battery bank for a small to medium car is on the order of a thousand bucks or two, and needs to be replaced every few years.
