Installing the flue-gas desulfurisation (FGD) technology in 12 coal-based thermal power plants within a 300-km radius of Delhi could lead to a dramatic 67 per cent reduction in sulphur dioxide (SO2) emissions, a new study has found. The study conducted by the Centre for Research on Energy and Clean Air (CREA) said there are 11 coal-based thermal power plants within a 300-km radius of Delhi -- Dadri TPP, Guru Hargobind TPS, Harduaganj TPS, Indira Gandhi STPP, Mahatma Gandhi TPS, Panipat TPS, Rajiv Gandhi TPS, Rajpura TPP, Ropar TPS, Talwandi Sabo TPP and Yamuna Nagar TPS. Additionally, the Goindwal Sahib power plant, located just outside this 300-km radius in Punjab, is also considered when making decisions about thermal power plants around Delhi. Between June 2022 and May 2023, these plants released 281 kilotonnes of SO2?? into the atmosphere. However, with the integration of the FGD technology, this figure could be reduced to just 93 kilotonnes annually, the study said. Despite a
