Germany intends to do away with burning coal to produce power, to stem carbon emissions, by 2038 at the latest. The plan there is to boost use of natural gas, the cleanest fossil fuel, and renewable energy. We, in lower-middle-income India, need to leverage our large coal reserves to proactively adapt proven technologies to rapidly shore up thermal efficiency in power generation, and carry out-diffusion of cutting-edge emission-abatement equipment nationally, even as we actively seek to raise the share of renewables in our energy mix.
The new Telangana plant of NTPC, India largest power producer, uses ultra-supercritical technology, and its upcoming Chhattisgarh plant is to incorporate advanced ultra-supercritical systems duly adapted for the Indian grades of coal. A conventional sub-critical power plant has a thermal efficiency of barely 30%, while supercritical and ultra-supercritical plants have efficiency levels of 45% or higher. It means generating 50% more power using the same amount of coal. Read more
