冰島工廠將二氧化碳變石頭

At the foot of an Icelandic volcano, a newly opened plant is sucking carbon dioxide from the air and turning it to rock, locking away the main culprit behind global warming.

在冰島的一座火山腳下，一家新開(kāi)的工廠正在吸收空氣中的二氧化碳并將其轉(zhuǎn)化為石頭，把全球變暖的元兇囚禁起來(lái)。

Orca, based on the Icelandic word for "energy," does its cutting-edge work at the Hellisheidi geothermal power plant in southwest Iceland.

這家名為Orca(源自冰島語(yǔ)，意思是"能源")的工廠在冰島西南部的赫利舍迪地?zé)岚l(fā)電站開(kāi)展這一尖端工作。

Fans in front of the collector draw in ambient air and release it, largely purified of CO2, through ventilators at the back.

該工廠的收集器在通過(guò)前端的風(fēng)扇吸入周?chē)諝夂?，?huì)去除空氣中的大部分二氧化碳，然后通過(guò)尾端的排氣扇將凈化后的空氣排出。

Dissolved in fresh water, the gas is then injected under high pressure into the basalt rock between 800 and 2,000 meters underground.

二氧化碳在淡水中溶解后就會(huì)通過(guò)高壓注入地下800米到2000米深的玄武巖中。

The solution fills the rock's cavities, and the solidification process begins -- a chemical reaction turning it to calcified white crystals that occurs when the gas comes in contact with the calcium, magnesium and iron in the basalt.

溶液填滿巖石的縫隙，凝固過(guò)程就開(kāi)始了。當(dāng)二氧化碳接觸到玄武巖中的鈣、鎂和鐵，就會(huì)產(chǎn)生化學(xué)反應(yīng)，轉(zhuǎn)變成鈣化白色晶體。

It takes up to two years for the CO2 to petrify.

讓二氧化碳石化需要兩年時(shí)間。
