**4. Conclusion & way forward**

Low Carbon Technology Vision for India together with strategies, challenges & opportunities in Green Power for energy security environmental sustainability are put forward in this paper covering Carbon Capture & Sequestration as a key factor. While there is growing trend of carbon dioxide emissions by energy sector since coal continue to play role in primary energy consumption, the urgency of CCS deployment in countries where coal is the main stay is very important. A pilot plant has been developed at RGPV University, for capture of CO<sup>2</sup> and converting the same into useful fuel like hydrogen for fuel cell application, methane for multiple applications and bio-diesel production through algae route. MATLAB simulations have shown that the recycling of CO back to the boiler will provide heat gain up to theoretical limit of 21.88%. Further, the energy penalty in regeneration of solvent using steam produced by solar thermal plant with an innovative Halide salt as thermal energy storage material will reduce by about 10%.

Climate change has already been experienced in many parts of the world therefore state policies need to support practices that successfully keep carbon in the ground, prevent deforestation, support agricultural practice that sequesters carbon and promote sustainable land use practices that reduce emissions. Policies should push especially the more prosperous communities towards less carbon intensive lifestyles, either through taxes or incentives or both. In addition, the path to zero-emissions must be progressive and in line with the progress of new and renewable technologies of hydro, solar and wind. The first step towards in this progressive path should be CCS.

Indigenous development of critical components of solar thermal plants for integration with CCS is nevertheless important. The following is a list of identified components that will be necessary to be developed within India at ultra-low cost by technology licensing and manufacturing technology transfer approaches by commercial entities (from abroad) to translate the existing technology for large scale adoption:
