反应释放的氢氧化钠回到第一步中重新利用，同CO2可以被贮存到地下曾经贮藏石油或天然气的地层，或者被回收利用做成汽油。
The reaction releases the sodium hydroxide for reuse in the first step, while the CO2 could be stored in underground reservoirs that once housed oil and gas or be recycled into gasoline.
以天然气产业为例，抽一口井，需要使用几百万加仑的水，由于使用了添加剂，用后又不回收做饮用水。
The gas industry, for example, USES several million gallons of freshwater when "fracking" a well, and the water is not recycled for drinking, thanks to the additives that are used.
