冰岛工厂将二氧化碳变石头

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.

在冰岛的一座火山脚下，一家新开的工厂正在吸收空气中的二氧化碳并将其转化为石头，把全球变暖的元凶囚禁起来。

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

这家名为Orca(源自冰岛语，意思是"能源")的工厂在冰岛西南部的赫利舍迪地热发电站开展这一尖端工作。

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

该工厂的收集器在通过前端的风扇吸入周围空气后，会去除空气中的大部分二氧化碳，然后通过尾端的排气扇将净化后的空气排出。

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会通过高压注入地下800米到2000米深的玄武岩中。

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.

溶液填满岩石的缝隙，凝固过程就开始了。当二氧化碳接触到玄武岩中的钙、镁和铁，就会产生化学反应，转变成钙化白色晶体。

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

让二氧化碳石化需要两年时间。
