    India's new emissions rules: challenges and opportunities .

    Most of the new FGD systems are likely to be wet systems as seawater systems are generally only used in coastal areas. Given that India is aiming for increased self- sufficiency in coal production, fewer power plants in the future are likely to be located in coastal areas, a factor that will favour wet FGD systems over seawater systems.
