If they become cheaper, we may all drive hydrogen cars in the future.

如果它们变得更便宜，我们将来可能都会开氢燃料汽车。

" So here, when we're using hydrogen cars, we can reach the ranges we have in normal petrol cars and fossil-fuel-driven cars — so, about 600, 700 kilometers."

所以我们使用氢气燃料汽车，就可以达到普通汽油汽车和化石燃料汽车行程的总和，大约是600-700公里。”
