Bioprocessing of Coal
Direct attack on the inorganic pyrite sulfur, applying a commercialized "bug" used for desulfurizing oil and coal. Italy has a pilot scale plant, but US coal companies are not interested in doing test-scale project. INEL has 100 lb./day test facility, but it's difficult and expensive to do a bioreactor cheaply enough to be practical ($2-10 per ton). Utility interest might get it going again.
