Evaluating Net-zero for the Indian Aluminium Industry - Marginal Abatement Cost Curves of Carbon

with the electricity consumed in the process, and the Similar to the decarbonisation trajectory of the cement emissions generated due to the nature of the process and steel industries (Elango et al. [...] However, due to a lack of data regarding the efficacy of specific energy efficiency 4.1 Energy efficiency in alumina refining measures in the context of alumina refineries, the achievable energy reduction is taken as the difference The average thermal energy consumption in an Indian between the energy consumption of the most efficient alumina refinery is 14 GJ per tonne of alumina, whereas process. [...] Given the scope Consequently, the MAC for energy efficiency measures for for reduction in thermal energy consumption, energy alumina refining was estimated as the weighted average 0efficiency measures will be one of the key steps in of the MACs and their abatement potential for all the the decarbonising of the alumina refining process. [...] The Figure 9 shows the breakdown of the delivered cost of benefits of the use of inert anodes are discussed in detail NG and biomass. [...] In the case of biomass, the cost of the product itself accounts for most of the delivered cost In our analysis, we assume that the entire thermal energy and is taken as USD 4.7 per gigajoule (TIFAC 2018).
