2.1. Water Usage in Coal to Power Applications | netl.doe.gov

So, in summary it can be said that gasification-based power offers efficiency benefits in the use of water. Raw water use in IGCC plants is lower than in pulverized coal plants. Without CCS, PC plants have a much higher steam turbine output, requiring more cooling water and condenser duties (typical raw water use ratio of 1.7:1.0).
