OSTI ID:7042860
A first-pass design and cost estimate indicates that the levelized constant-dollar cost of gas for a 125 billion Btu/day plant to convert western subbituminous coal to substitute natural gas (SNG) using KRW gasifiers is $4.70/MMBtu. Process development allowances (PDA) increase the gas cost to $5.09/MMBtu. The levelized constant-dollar gas cost for a scaled-up 250 billion Btu/day plant is estimated at $4.17/MMBtu, indicating that smaller plants can be constructed with less capital risk while producing methane at only slightly higher costs.
