22 The extent to which CCUS will be effective in achieving net zero emissions, as per the Paris Agreement, depends on the efficiency of technology used. Retrofitting is attachment of carbon capture facilities to existing Cement plants. As per IEA, retrofitting is necessary from 2020 existing plants to achieve our targets. Different technologies that can be used for Carbon Capture are:  Amine Scrubbing  Full Oxy-Fuel Combustion  Partial Oxy-Fuel Combustion  Calcium Looping  Direct Capture As per reports, Direct Capture and Calcium looping is expected to grow fast compared to others. The storage capacity of CO 2 is enormous and only 3% of total global storage capacity is being used. Thus, it is high time we need to brace up for the major shift. New technological innovations in carbon capture technologies are the need of the hour with extensive research. 2.3. Use of Renewable Energy Another alternative to go greener is long term renewable energy off take contracts between industrial customers and power producers, known as ’Power Purchase Agreement’ (PPA). Solar Energy, Wind Power Energy, and Biomass are some of the most common sources of renewable energy. Table 4 shows the growth of Renewable Energy in India till 2020. Installed Capacity (GW) Sector As on 31.03.2014 As on 29.02.2020 Growth Renewable Energy(Excluding large hydro above 25MW) 35.5 86.8 144% Solor Power 2.6 34.4 1208% Wind Power 21.0 37.7 79% Biomass, Small Hydro & Waste to Energy 11.9 14.7 24% Table. 4 Growth of Renewable Energy Utilising these renewable energies for power generation at Cement plants shall help reduce Carbon emissions drastically. By installing solar power plants and solar water heating systems, cement plants can not only meet the obligations under both RPO and PAT mechanisms but also reduce greenhouse gas (GHG) emissions. Based on the available area within a cement plant, we can install the solar power plant considering the solar technology suitable for that geographical terrain. A wind turbine transforms the kinetic energy available in the wind into mechanical or electrical energy that can be used for any required application. The wind farm is located in an area of high wind with power “wheeled” through the national transmission grid. The cement manufacturing plant can utilize this energy for the processes. Biomass can be converted to energy by suitable processes which shall help cut down the use of conventional sources for the generation of power and electricity. According to the 2018 Climate scope report India ranked second among the emerging economies to lead to a transition to clean energy. India has the huge capacity and scope to utilize Renewable Energy for Country’s growth journey.
