Aluminum Industry Opportunity
- GHG targeted : Carbon Di Oxide, PFCs- Carbon Tetra Flouride, Carbon Hexa Flouride.
- Base level of emissions of that particular GHG: India has about 700,000 tonnes of Aluminum being produced per year. The CO2 is emitted from smelting process and PFCs are emitted from Anode Effects an operational problems. Most Indian plants in Private or Public Sector have been established in 1940s and have old process of Hall-Heroult. This can be safely assumed to have 1.5 tonne of CO2/ tonne of Aluminum & about 1 kg of C2H4/ tonne of Aluminum, & 0.1Kg/tonne of Aluminum. Due to 6000-9000GWP of PFCs, this would amount to 7.5 tonne of CO2e/Tonnes of Aluminum. A total of about 5 million tonnes of CO2e is GHG emissions from Aluminum Sector in India alone.
- Profile of the emitter: There are four companies Nalco, Indal, Hindalco, Balco first two being in government sector with limited access to Technology, Cash & high access to government policy interventions. Hindalco & Balco are in the private Sector. Most of them have their own captive Coal based power plants.
- Quantum of Emission per year: A total of ~5 million tonnes of CO2e is emitted per year.
- Technology to Reduce PFC/GHG emissions: Various Cell Technologies can be retro fitted on these existing plants. Retro fittable Technology for PFC reduction is not yet ready as per one US EPA web site.
- Level of Mitigation achievable by that Technology: 40% reduction has been achieved in US voluntarily by its aluminum Industry & it is safe to assume that atleast 40% reduction i.e. 2 million Tonnes of CO2e can be reduced in Indian Aluminum Industry per year.
- Barriers to Project Development: Technology Providers & costs for the technology seem to be the key barriers.
