Abstract	Coal gasification represents one of the most promising technology for large, medium and small scale hydrogen production for distributed power generation. Currently, the application of “zero emissions” hydrogen production and power generation technologies involves very high capital and operative costs. This need a great scientific and technical effort in order to optimize processes and equipments, thus reducing hydrogen production cost. In this field, Sotacarbo is tuning technologies for the development of integrated processes for the combined production of hydrogen and electrical energy through coal gasification, with CO2 capture. The process has been tested in a pilot platform, located in the Sotacarbo Research Centre in Carbonia (South-West Sardinia, Italy). The platform includes a 5 MWth demonstrative plant and a fully equipped 200 kWth pilot plant, both based on a fixed-bed, updraft and air-blown gasification process. This paper reports an analysis of the main results obtained in the first experimental campaigns on the platform, with particular reference to coal gasification and to the global carbon balance. The experimental tests have been carried out with different operating conditions. In particular, a series of experimental tests have been developed in order to evaluate the possibility to substitute air with a mixture of oxygen and carbon dioxide as gasification agent, in order to increase CO2 partial pressure in the carbon capture section, rising its performance.
