Burning coal cleanly IS A GOOD SOLUTION.
1. Cost of removing impurities. Of course removing the impurities has a cost. Otherwise coal would have been used instead of oil decades ago. It's at $40 a barrel that the cost becomes worth it.
2. Disposal of extracted impurities. We are talking about SO2 which can be oxidized to sulfuric acid for which there are myriad uses. We can also reduce the SO2 with coke to produce harmless CO2 + sulfur. Sulfur has a price too; it is saleable.
Mr. Janko reports about that fine achievement in Europe of building a plant that burns lignite instead of oil. Both of your objections, 1. cost of removing impurities and 2. disposal of the impurities, are present there and yet the energy advantages make it economical. Here is a gorgeous real example. In the future the gap between the price of power generated from burning lignite and the price of power from burning oil will widen a lot.
