Coal Gasification with Carbon Capture could be a game changer for India-Shifting Coal from an Energy Commodity to a Chemical Feedstock

Nuclear has been a good option for grid to be 90~100% green.
the article is mostly about invention on thorium and higher efficiency and lower spent wastage.
Based on what i know nuclear, again a limited deposit, could only be a good option for green grid, provided it offers a smaller sized as well as shorter start-up cycle nuclear plants.someday smaller&shorter startup cycled nuclear plants may become reality.
But, the most cleaner grid is solar+hydrogen.The battery banks/storage have found its place in existing so called greener grid but that is according to me cant be considered 100% green.
