H2A Case Study: Current Central Coal without Sequestration
Project Summary
| Full Title: |
H2A Case Study: Current (2005) Hydrogen from Coal without CO2 Capture and Sequestration |
| Project ID: |
231 |
| Principal Investigator: |
Mike Rutkowski |
| Keywords: |
Coal; hydrogen production; gasification |
Purpose
The objective of this analysis was to prepare capital and operating cost data to be used to arrive at a
plant gate cost for hydrogen produced from coal gasification. Hydrogen cost was determined by first
preparing a plant design for hydrogen production, based on currently available process technology, and
meeting current permitting regulations for environmental compliance. This baseline plant does not
capture CO2.

Products/Deliverables
| Notes/Comments: |
To arrive at a cost estimate for hydrogen, the design included commercially available process technology obtained from verifiable sources. The plant utilized commercially available technology including a Wabash River-scale Conoco-Phillips (EGas) gasifier, conventional gas cooling, commercial shift conversion and acid gas cleanup, commercial sulfuric acid technology, and commercial pressure swing adsorption (PSA). The EGas gasifier is the gasifier of choice for this study since it has been operated on both bituminous and sub-bituminous coals. |
