Unfortunately, we're still working out the best ways to produce, store, and deliver biohydrogen.

不幸的是，我们仍在寻找生产、储存和输送生物氢的最佳方法。

Then, they manipulated the carbon and nitrogen sources they gave these bacteria to see which maximized biohydrogen production.

然后，他们操纵给这些细菌的碳和氮源，看看哪个能最大限度地提高生物氢的产量。

But it's their ability to produce hydrogen, known as biohydrogen in this case, because it comes from living things, that has scientists excited.

但让科学家兴奋的是它们生产氢的能力，在这种情况下叫做生物氢，因为它来自生物。

Some engineers think biohydrogen could be the fuel of the future because it can produce a lot of energy with little or no carbon emission, and the main byproduct of burning hydrogen is water.

一些工程师认为生物氢可能是未来的燃料，因为它可以在很少或没有碳排放的情况下产生大量能源，燃烧氢的主要副产品是水。
