From my previous research, IPL had two contracts due to expire. One for 10.5 Pj and one 14.5 Pj. Maybe they are hedging their bets, and keeping the 10.5Pj for CNX? You just feel IPL have to be involved somewhere, though I would have expected them to go direct from Syngas to NH3 rather than going to CH4 and back.
Interesting times!
