For both the United States and the World coal is the most abundant fossil fuel but it is also the most polluting. Coal's pollution problems include the emissions of NOx, SO2, mercury, submicron particles containing toxic heavy metals, carcinogenic polynuclear aromatic compounds, and massive emissions of the greenhouse gas CO2. While technologies to limit some of these problems are available, they are individually expensive and that expense is additive. Gasification of coal with oxygen, CO2, and H20 has been suggested as a technology which would solve all of coal's pollution problems, but this approach suffers from the high cost of oxygen and from the fact that gasification is a slow and hence expensive process. EER has discovered a radically new method of combustion which, like oxygen gasification, solves all of coal's pollution problems, but without the expense of producing oxygen and with greatly reduced cost for the gasification step.

对美国和世界来说，煤炭是最丰富的化石燃料，但也是最污染的。煤的污染问题包括NOx、SO2、汞、含有有毒重金属的亚微米颗粒、致癌多核芳香族化合物的排放以及温室气体CO2的大量排放。虽然限制其中一些问题的技术是可用的，但它们各自都很昂贵，而且费用是附加的。已经提出用氧气、CO2和H2O气化煤作为将解决煤的所有污染问题的技术，但是这种方法的缺点在于氧气的高成本以及气化是缓慢且因此昂贵的过程的事实。EER发现了一种全新的燃烧方法，与氧气气化一样，它解决了煤的所有污染问题，但没有产生氧气的费用，并且大大降低了气化步骤的成本。
