Cost-efficiency with sensitivity anal. of H-2 prodn. based on coal gasification was carried out for 2 variants of the technol. based on bituminous coal either equipped with a CO2 sequestration (CCS) unit or without it. Life cycle costing anal. was performed. Cost of purchasing of CO2 emission allowances (variant without CCS) and investment costs (variant with CCS) were crucial factors for the H-2 prodn. cost-efficiency.
