In the major aluminium producers in the world, the energy requirements for aluminium electrolysis are in the range of 14 to 15 kWh/kg of Al which is more than twice of the theoretical energy requirement for the reduction process. It is also a fact that the operational temperature of Al-electrolysis is about 1233 K which is 573 K above the melting point of Al-metal. A theoretical calculation of heat balance suggests that a reduction of about 373 K in the operational temperature of Al-electrolysis could save about 1 . 1.5 kWh/kg of Al. Another matter of concern in Al-electrolysis is the limitation of interelectrode spacing and frequent anode changing. A suitable inert anode would reduce energy losses besides saving high quality carbon uses as anode. The R & D activities undertaken by the CECRI to study such problems are discussed
