Volvo adds a fuel cell to its electric C30, but forgets the hydrogen tank

Volvo C30 electric with fuel cell and reformer

The C30 from Volvo comes with a gasoline or diesel engine (in Europe), but the Swedish manufacturer also looks to the future, he has built some prototypes with an electric powertrain. On batteries, their range is very limited, less than 100 miles. Just add more batteries if you want to drive more. This is what Volvo could have done, but they chose to go another way, with a fuel cell.

There’s several reasons to use a fuel cell, and one of them is price. A large battery pack is as heavy as it is expensive. I’m not saying a fuel cell is cheap, but it certainly can compete on price. The choice of a fuel cell will also give Volvo engineers an opportunity to get a closer look at this technology. Hydrogen and fuel cell, and more as Volvo made the strange choice to avoid using an hydrogen tank.

The Swedes will use a reformer instead. Pretty much like an engine, it’s a machine that converts regular gasoline into hydrogen. It sounds convenient, but it kills the main advantage of fuel cell vehicles: that Volvo C30 will not be zero emission. The reformer makes hydrogen, but there’s no way to avoid making CO2 as a byproduct. That was the reason General Motors, Mercedes and most other manufacturers gave up reformers years ago. It’s very strange to see Volvo’s going back to it…

A small tank gives the electric C30 a range extended by 150-miles. Volvo will build 2 electric C30s with a fuel cell next year, and they will go through a long panel of tests in 2012.
