煤炭储量可以满足世界几个世纪的能源需求。然而，如果不消除向大气中排放的二氧化碳，煤炭的长期使用可能会严重减少。我们提出了一种安全、持久的二氧化碳处置方法，该方法是将二氧化碳与丰富的原料化学结合，形成稳定的碳酸盐矿物。我们讨论了原材料的可用性和潜在的工艺设计。我们认为我们最初粗略估计的成本约为3美分/千瓦时，令人振奋。在全球变暖或对全球变暖的看法导致二氧化碳排放受到严格限制的情况下，二氧化碳固定技术的可用性将起到保险作用。如果要用煤炭来满足不断增长的世界人口对能源的日益增长的需求，这种技术的实施很可能是不可避免的。
Coal reserves can provide for the world`s energy needs for centuries. However, coal`s long term use may be severely curtailed if the emission of carbon dioxide into the atmosphere is not eliminated. We present a safe and permanent method of carbon dioxide disposal that is based on combining carbon dioxide chemically with abundant raw materials to form stable carbonate minerals. We discuss the availability of raw materials and potential process designs. We consider our initial rough cost estimate of about 3{cents}/kWh encouraging. The availability of a carbon dioxide fixation technology would serve as insurance in case global warming, or the perception of global warming, causes severe restrictions on carbon dioxide emissions. If the increased energy demand of a growing world population is to be satisfied from coal, the implementation of such a technology would quite likely be unavoidable.
