the problem is that once you have ERC running it produces so much formic acid the price of your durm collapses to just a dollar or two.
Hence the companies thinking of implementing ERC will not as the process isn't commercially viable.
Hence the switch in R&D to Syn gas and I also suspect the reason for delays in grants and the actual projects themselves.
It is all starting to make sense - the delays are to enable a viable business model to be found. Once proven GE can now buy out Mantra for a tenth of what it would have cost just a couple of years ago and haven't had to do any of the R&D.
