Absolutely. Those vehicles tend to have a much higher impact on the emissions compared to a personal car. They operate for longer times and they have more emissions.
I think it's the same thing as the question that was asked before. We need to look at those total life cycle costs. Fuel cell has a big advantage here. It's much less energy intensive to produce. It's the manufacturing part. The life cycle cost of the fuel cell from cradle to grave is also very attractive.
Today at Ballard, we recycle the fuel cells, so when a fuel cell reaches the end of life we can recycle. We rebuild it using the same material and recover 95% of the precious metals that are there. I think it's important to look at the use case as well as the total life cycle cost.
