"Efficiency of removal is just one part of the variables that goes into deciding whether the product attributes are superior or not. There is also consideration placed on waste, transportability, effect on inherant qualities of the coal, etc."

That is fine, lets go through your points of comparison and see how they stack up.

Waste - comparable, water extracted from both to be used for industrial/agricultural.

transportability - Exergen winner, as it can be located at the coal deposit not at the power station.

qualities of the coal - Exergen winner, final moisture content is lower and stays hydrophobic so moisture is not reabsorbed.

"I'm not sure whether they are in a position to rollout their pilot plant modules into a 2Mtpa project just yet"

Plenty of stuff on the net if you had bothered to look. That is why Exergen has been eager to get coal allocation because they are at this stage to commercialisation.

"Is the water that is extracted industrial grade pre or post cleanup? My understanding is that Exergen squeeze the water out and then process the water to bring it to a grade that is safe for disposal. This cleanup process is likely to involve chemicals and or expensive RO technology."

No apparently they are going to use a water treatment autoclave that evaporates then condenses the water to purify. Out of interest how does ESI purify the water that is released by the coal?
