Coal is an important fossil fuel because of its abundancy and price stability. However, coal produces more CO2 than other fossil fuels and has disadvantage from. the standpoint of global warming. Gasified coal contains both H2 and CO, and by shift reaction CO is converted to CO2. Hence, H2 and CO2 can be effectively produced from. coal when CCS (Carbon Capture & Storage (or Sequestration)) is socially accepted and commercialized, and hydrogen production by coal will be even more promising.
