Vernon Roan on hydrogen as fuel for future cars

EarthSky

Hydrogen should be a fuel for the car of the future, according to a June 2010 report by the U.S. National Research Council or NRC. We spoke with Vernon Roan, who chairs the committee for the NRC on hydrogen cars and fuel.

全國研究理事會在今年6月的一份報告中稱，氫燃料應成為未來汽車的主要燃料之一。本站記者采訪了理事會委員長弗農·羅安，他主管相關領域的研究。

Vernon Roan: Eventually, we are going to be forced into some kind of synthesized fuel economy. And hydrogen is by far the most likely, because it’s a super fuel. We’re gonna wind up there, because we’re going to run out of fossil fuels. It’s not gonna happen in the next decade. But eventually it’s going to happen.

弗農·羅安：人們最終會進入合成燃料時代。目前為止氫燃料前景最好，因為它是一種超級燃料。我們最終會依賴它，因為化石燃料總有用盡的一天。雖然未來10年不太可能，但這一天遲早會到來。

Hydrogen fuel cells work by combining hydrogen and oxygen to produce electricity. The technological problems of doing that efficiently and economically are yet to be solved.

氫燃料電池通過氫氧結合產(chǎn)生電能。如何使這一過程高效、經(jīng)濟依然是個有待解決的技術問題。

Vernon Roan: We do recognize that this is a long term technology, so it’s going to take years of continued R&D, and a lot of effort on the part of industry as well as government.

弗農·羅安：我們意識到這項技術走向成熟還需要很長的時間，在接下來幾年里我們會一直投入研發(fā)工作，同時企業(yè)和政府也需要花費很大的努力。

Roan said there’s still not a good way to carry significant amounts of hydrogen for long distances. And there is the problem of where to get the hydrogen. Today, nearly all hydrogen for cars comes from fossil fuels. But the research is on to get it from wind and solar. And while the costs of making fuel cells remain high, Roan said they've dropped by 30 percent in the last two years.

羅安表示，目前沒有什么好方法能遠距離運輸大量的氫。此外，氫的來源也是個問題?，F(xiàn)在幾乎所有氫燃料汽車使用的氫都來源于化石燃料。盡管制造燃料電池的成本居高不下，羅安表示這一成本近兩年來已經(jīng)下降了30%。?
