national laboratories in northern California: Lawrence Livermore and Sandia.

北加州的兩個國家實驗室：勞倫斯‧利佛莫爾和桑迪亞。

They're located across the street from each other in Livermore, about an hour east of

他們位在利佛莫爾，彼此隔街相望，約一個小時的車程

San Francisco.

在舊金山東部

The environmental advantages of hydrogen are crucial:

氫氣的優勢對環境攸關重大

When hydrogen is used as a fuel in the internal combustion engine, the greenhouse gas emissions

當氫氣被用做內燃機燃料時，溫室氣體的排放

are far lower than a conventional gasoline-powered vehicle.

遠遠低於傳統汽油動力車輛

The only emissions coming out of the tailpipe are water vapor and very low-levels of criteria

唯一從排氣管排放出來的是水蒸氣和非常低量標準的

pollutants such as oxides of nitrogen; below super-ultra-low emission vehicle standards;

如氮氧化合物的汙染物；遠遠低於車輛排放標準

these are very clean vehicles for the environment.

這些都是非常清潔的環保車輛

It's all part of a Department of Energy initiative.

它是美國能源部倡導的一部分

What we are trying to do is to get hydrogen vehicles and the refueling infrastructure

讓氫燃料汽車和基礎加氣設施導入大眾

introduced to the public, so the public can become aware of the environmental and energy

也是我們正在努力的一環，使民眾能夠意識到環境和能源

security advantages of hydrogen as a transportation fuel.

以氫氣作為運輸燃料的安全性的優點

Hydrogen buses like these, leased from Ford Motor Company -- are also highly fuel-efficient

氫動力巴士是這樣來的，從福特汽車租用而來 -- 也高度節省燃料

-- up to 25-percent more efficient than their gasoline-fueled equivalents.

和傳統汽油為燃料量相比，效率高達25％

Here at Livermore, our buses, our taxis, cycle our site constantly, all day long and we're

在利佛莫爾這裡，我們的巴士、計程車，全天候不斷繞行我們的實驗基地，我們

putting hundreds of miles a week on these vehicles. We'll probably, in terms of mileage;

這些車輛每星期行駛數百英里。我們可能，換算成行駛里程

we're probably the most extensive project that's ongoing now in the DOE program.

我們可能是現正進行中，美國能源部計劃最廣泛的項目

And so the data that we will be gathering will be shared with the automobile manufacturers,

因此，我們會將收集的數據與汽車製造商共享

with Ford, and also with the hydrogen producer, in our case, it's Air Products, uh, is providing

像是福特，以及與氫氣生產商，在我們的案例中，它是氣體產品公司，嗯，是提供

a refueling site here at Livermore.

在利佛莫爾這裡是氫氣填加站

Refueling a hydrogen vehicle is far different than filling up a gasoline-powered car.

加氫氣車和加油車相比，很不一樣

This is the Air Products refueling station, used by the Lab's two buses and a hydrogen-powered

這裡是氣體產品公司填加站，實驗室的兩輛巴士，以及一部氫動力

Prius.

Prius 都使用氫氣

It's all computerized, but instead of gallons, units of hydrogen are measured in kilograms.

全部電腦化，不以加侖計算，氫的單位是以「千克」來測量

There are also safety procedures that need to be followed.

也需要遵循安全程序

This is telling me now that I need to ground the trailer and the shuttle bus.

它現在告訴我，我需要接地拖車和巴士共同運作

There's no gas cap to remove. Instead, there's a valve that must be opened.

它沒有加油箱蓋要轉開。相反地，有個閥門必須打開

What I need to do next is to release the red button here so that I can begin the fueling

下一步我需要做的是按下這裡的紅色按鈕，這樣我才可以開始加氣

process by releasing the solenoid. I press the red button.

透過放開電磁閥的過程，我按下紅色按鈕

The flashing light lets me know the solenoid has been released so the fuel can start to

閃爍的燈光讓我知道，電磁閥已經鬆開，如此一來，氫燃料就可以開始

be released to the vehicle.

注入車內

OK, now I'm attaching the fueling nozzle to the refueling receptacle and locking it in

好了，現在我把加氣噴嘴連接到插座上並且將它

place [click] and the fueling process has begun.

固定住，加氣程序就開始了

Under the hood, you can't see much difference in a hydrogen-powered engine. These buses

引擎蓋下，你沒辦法看到氫動力引擎有多大的差別。這些巴士

have a 6.8-liter supercharged Triton V-10 engine, with just a few modifications, such

有一個6.8 公升超增壓的Triton V-10 引擎，只需少許的修改，例如

as alternate materials for valves and other parts that might become brittle when exposed to hydrogen.

閥門和其它零件接觸到氫氣時，可能變脆，因此要換成替代材料

The buses, and the two labs' other hydrogen technologies were introduced to the public

這些巴士和兩個實驗室的其他氫技術，被介紹給民眾

at a noontime ceremony in downtown Livermore.

在利佛莫爾城中央一個中午舉辦的儀式

As a national security lab, we think very broadly of national security, including energy

作為國家安全實驗室，我們廣泛考量到國家安全，包括能源

security, and this is really important, this hydrogen fuel, to energy security.

安全性，這非常重要，因為這種氫燃料，涉及能源安全。

This can be produced using entirely domestic resources.

完全可以使用美國境內的資源來生產。

Using hydrogen technologies like these hydrogen buses is a great way to bring the technology

使用像這些氫動力巴士的氫氣技術，是將這項科技導入

into the community and to provide outreach and education, especially on ways to reduce

社區的好方法，並藉此提供宣傳和教育，特別是針對如何減少

our dependence on imported oil and reduce greenhouse gases and air pollution.

對進口石油的依賴，以及減少溫室氣體排放和空氣污染。

This project shows the firm commitment of Lawrence Livermore, Sandia, AirProducts, and

而這項專案也顯示勞倫斯·利佛莫爾、桑迪亞和氣體產品公司

Ford to the advancement of clean energy technologies in their communities.

以及福特汽車對提供社區清淨能源的堅定承諾

You're truly leaders in launching this green economy and behalf of DOE, I applaud you for your efforts.

你們是真正啟動綠色經濟的領導人，而我代表能源部為你們的努力拍拍手

It will obviously take many more years before alternative clean-energy vehicles outnumber

很顯然地，替代性的清潔能源車的數量，要超過傳統汽油車，仍需要很多年

those powered by gasoline. But slowly, with many more scientific advances along the way,

但是，慢慢地，這一路上還有更多的科學技術會跟著進步，

it seems a sure bet that there will be hybrids, all-electric, and hydrogen in our nation's

這似乎是一個肯定要下的賭注，未來將有混合動力，全電動和氫動力系統會用在我們國家的

future transportation system.

未來交通系統上
