This analysis explores the technologies available for reducing emissions of acid gases, including hydrochloric acid (HCl) and hydrofluoric acid (HF), from coal-fired power plants. It finds that there have been significant developments since the U.S. Environmental Protection Agency originally adopted limits on such emissions in 2011, resulting in greater emission reductions and lower compliance costs. In addition, the analysis estimates total (annual) costs of complying with various HCl limits, showing that the costs for the entire fleet to meet a substantially lower limit would be modest.
