・The Queensland state government has been promoting this PJ by recognizing IGCC & CCS is “a kind-of-must”technology in order to reduce GHG globally for the future.・ZeroGen Pty Ltd. decided that MHI joined her world-first commercial scale IGCC+CCS PJ.

・It was officially concluded and approved by CCC (Clean Coal Council) of the Queensland state government, by highly evaluating the successful result - its quality, reliability and operation ability - of the 250MW Nakosodemonstration PJ, to stop her Stage 1 demonstration PJ (120MW) and to step up directly to the commercial scale PJ (530MW) with MHI.
