国企引领世界生物新能源开发

It looks like just a bunch of green goo, but the algae surging through these pipes could be the key to a low-carbon future.

goo就是那种黏黏的、看上去很恶心的胶质物。

Inside this green house in Langfang, China, researchers at a private company called ENN are studying how to turn algae into energy or biofuel.

-Could you use this to power your car or fly your airplane, for example?
-Everywhere you can use diesel.

Continental Airline has already completed a successful test flight using biofuel, in part, created from algae from another company. Oil giant Exxon, often accused of lagging in its pursuit of alternative energy, is now one of many companies jumping on the band wagging, pouring money into algae energy research.

-If successful, we see biofuels going into our refineries, being processed with other petroleum products and coming out going straight into the distribution system and into gasoline stations around the county.

So why is algae so attractive? Well, it can multiply in size several times a day. It feeds on massive amounts of carbon dioxide or CO2, a greenhouse gas, cleaning up emission as it grows.

-One major step is genetic engineering. These are different strings of algae. The goal is to cultivate a string that has the highest oil content, absorb CO2 the fastest and therefore grows the fastest.

-What's inside about ENN is there are incredible innovation in creativity. They have developed integrated energy systems, trying a bunch of new energy processes and putting them all together in a very innovative way.

US Energy Secretary Steven Chu even paid ENN a visit during a trip to China. The company already powers 70 medium-size Chinese cities with natural gas, but wants to introduce a more efficient system.

-We believe that to develop clean coal technologies really you have to introduce renewable sources to really make the process clean.

clean coal technologies 洁净煤技术
洁净煤技术是指从煤炭开发到利用的全过程中旨在减少污染排放与提高利用效率的加工、燃烧、转化及污染控制等新技术。

If it works, in the end, (it) will be a totally integrated process that leaves the smallest carbon footprint possible and uses whatever carbon emissions that are produced to create more energy.
