Development of a Hydrogasification Process for Co-Production of Substitute Natural Gas (SNG) and Electric Power from Western Coals

Performer: Arizona Public Service

Project No: FC26-06NT42759

Project Description

The objective of the proposed work is to develop and demonstrate at an engineering-scale, a coal hydrogasification-based process for co-production of synthetic natural gas (SNG) and electricity with near-zero emissions meeting the following performance targets: (1) overall process efficiency greater than 50%; (2) SNG cost less than the market value of natural gas; (3) capture and sequestration of CO2 equivalent to 90% of emissions from power production; (4) water usage at least 50% less than SNG from gasification/syngas methanation; and (5) the ability to use low-rank Western coals.
