The economic benefits of producing high-value, clean energy products from low/no cost feedstocks are significant. Gasification recovers the full energy potential of these feedstocks while greatly reducing disposal costs and environmental impact.
Preliminary estimates show production costs of coal-to-synthetic natural gas (SNG) are about $113/’000 cm, less than half of average price of natural gas ($250/’000 cm).
Today’s cost of gasoline is ~$800 a ton, whereas production using coal gasification would cost $210/t. Although the capex of a coal-to-gasoline plant is higher than a coal-to-SNG facility, the economic benefit is striking for both cases.
Economics of Gasification
Gasification has been used on a commercial scale for more than 50 years in the chemical, refining, and fertilizer industries, and for more than 35 years in the electric power industry. There are more than 140 gasification plants currently operating worldwide with impressive results:
