This article is from India, about our increasingly familiar African friends, Sasol - who are planning/constructing Coal-To-Liquid plants in India, among other places - and some of their efforts to ameliorate the environmental effects of coal use, especially the conversion of it to liquid fuels.
The excerpt:
"... Sasol, the world's biggest maker of fuel from coal, is pioneering a plan to sell carbon credits by converting a greenhouse gas into nitrogen and oxygen, also earning it income. Based at two plants in South Africa, the project will convert nitrous oxide and is aimed at cutting emissions equivalent to about 1 million tonnes of carbon dioxide a year."
Sasol does have very assertive efforts underway, and on the way, to tackle CO2 directly, as you will have seen in our other dispatches. In this article, their plans to abate oxides of Nitrogen, also produced by the processes of coal use, is discussed. The importance herein is that, even though CO2 is the most widely demonized by-product of carbon use/combustion, because it is the most voluminous, it is not the only gaseous pollutant, and certainly not the most potent of the "greenhouse" gasses.
Technologies exist, and are being reduced to commercial practice, to recycle, reuse, and profit from, all the by-products of coal use - whether we are burning it for power, or converting it into liquid fuels and chemicals.
