The spongy iron will be an excellent substitute for steel scrap used by electric steel melting furnaces. (v) Replacement of Pig-Iron: The spongy iron can also replace pig-iron for large iron foundries where there is facility for hot blast cupolas. The pig-iron thus saved could be supplied to the small scale units. (vi) Shortage of Coking Coal:

The operation of the small scale "Sponge Iron Reactor" (SIR) showed that the hydrogen produced is sufficiently pure for use in any kind of fuel cell (CO <10 ppm). The steam-iron process is one of the oldest methods of producing hydrogen. It is a cyclic process for water cleavage, whereby coal is …

Direct reduction iron or sponge iron is an old method for producing hydrogen (Milne et al., 2006; Peña et al., 2010; Biljetina and Tarman, 1981) that was replaced by more efficient and economic processes.Recently, the interest in sponge iron as a hydrogen production process has grown again, although the technology still has some major technical and economic challenges to …
