Toyota Motor Corporation, in cooperation with its bus and truck arm Hino Motors, has developed a new hydrogen fuel cell bus.

The Toyota FC Bus is based on the Hino hybrid non-step route bus, but equipped with fuel cell systems derived from Toyota’s Mirai FCEV. Everything is just scaled up for this larger vehicle.

There are two fuel cell stacks (114 kW each) and two synchronous motors (110 kW and 335 Nm each). Hydrogen is stored in eight 70 MPa tanks similar to those from Mirai and there is a NiMH battery pack.

The bus can also power homes (or other facilities) during emergencies using CHAdeMO output up to 9.8 kW.

On January 9, the Toyota FC Bus entered service on the Toyota Oiden bus route in Toyota City, Japan.

“Toyota and Hino will verify the feasibility and effectiveness of the fuel cell bus through testing involving commercial operation on regular routes on public roads and will feed back the results into R&D. Hydrogen fueling of the bus will be carried out at Toyota Ecoful Town, under a New Energy and Industrial Technology Development Organization project.

The verification testing will be conducted with the cooperation of Toyota City as a part of public fuel cell bus road trials and emergency external power supply testing that began in 2010 under the Toyota City Low-Carbon Verification Project, which has been selected as one of the Next-Generation Energy and Social System Demonstration Projects being promoted by the Ministry of Economy, Trade and Industry.”

Main specifications of the fuel cell bus:

Just another example where going right to Electric is the best option.

Here it comes.. Soon to roll over its competitions.

Did you mean competitors?

+1. Yes.

It will be interesting to see the pricing. They need to get the price down to a very low level to even have the chance of competing with electric buses.

Already today the TCO for electric buses are lower than any other kind of bus in many places and will be the natural option for many when they replace buses the next time.

Fuel cells might get a portion of the bus market. But their real target should be the heavy truck business.

I wonder how much that costs to fill with hydrogen.

A fuel cell bus is likely to have great range and doesn’t have to lie idle while charging–thus reducing the number of total busses needed in the fleet to cover very long range routes.

Yep. Not to mention that it can pack more people. While electric buses are 40 ft long, fuel cell busses can be 60 ft long.

Next up – large trucks.

BYD released already a 60 ft electric Bus…
I think Busses might be electric if the company has no night shifts. Then it should be cheaper than gas or hydrogen.

But as Three electric mentioned right, if they drive all day (or nearly all day) a normal bus will reduce needed numbers, which is also a huge saving.

Buses are driving slow (city traffic) normally, here wins the electric motor. But when electric trucks are needed, a FCV is the only way to go. Trucks drive “fast” and long distances. I don’t know about the situation in USA, but in Europe the Trucks have a realistic range between 1000 and 2000 km (up to 1250 miles). A a tank of up to 1000 liter Diesel. No battery can match that size (today). Only Li-Air might do this some day, but Li-Air is 20 years till production.

Totally agree.
Use of hydrogen for small vehicule or frequently at rest is a non-sense.
It’s not because it’s doable that it’s the best thing to do.
On the other end to move big load for long distance non-stop is certainly quite interesting.
Big rig or boat is a good field of play.
Plane have a safety concern with it but train have is easy to connect to the electric grid, altought no cheap to do it.
Now big rig and boat use diesel that has a better energy density than hydrogen and use it at a much better efficiency than small engine, the best of them are close to 40% and that is about the maximum efficiency of fuel cell from well to wheel and leave the question of carbon benefit in trouble.
The only gain left would be a much quieter transportation.
It’s certainly a good thing, but is it enough?

Wondering if hydrogen buses will attract suicide bombers, because of the multiplying effect of a highly compressed tank of fuel rupturing, spraying, then burning…

One of the very few interesting uses of a Hydrogen fuel cell is on the Moon for power during the long Moon night. You can have a large energy storage with liquid Hydrogen and liquid Oxygen tanks. The The energy yield is lower than with batteries but the required mass to orbit/KWh is lower since you essentially carry just empty tanks. You also need Hydrogen and Oxygen reserves anyway so the electrolysis device for the Moon water is already there.
