Domestically, rising concern over environmental degradation associated with coal plants and competition from abundant natural gas and renewable generation have challenged coal’s dominance. From 2000 to 2017, more than 100 GW of U.S. coal-fired generation was retired, according to M.J. Bradley & Associates. Coal presently accounts for approximately 30 percent of overall electricity generation in the U.S., down from nearly 45 percent in 2009. Recently, the coal industry has focused on making a case for the reliability benefits coal plants offer and the national security advantages of domestic coal production, as well as the importance of maintaining fuel diversity in the electric sector. However, coal still faces a multitude of policy, technological, and financial obstacles to its remaining an indispensable source of power in the 21st century. Carbon capture, utilization, and storage (CCUS) technologies constitute an important opportunity for coal. Decades of public and private research, development, and demonstration (RD&D) have led to crucial breakthroughs in CCUS on coal-fired power plants. Although CCUS is confined to a handful of power plants and faces barriers to widespread adoption in the power sector, CCUS has shown promising results in industrial uses, and results from power sector applications have been encouraging. CCUS is an exciting technology area with the potential to deliver environmental benefits, improved reliability, and increased economic activity. These broad benefits have attracted support for CCUS from a wide range of stakeholders. With thoughtful policies at the federal, state, and local levels and continued investment in RD&D, the deployment of CCUS technology could be increased to improve the environmental performance of coal-fired power plants and other industrial processes. Such action could enable coal to deliver the benefits the industry cites while improving environmental performance—making coal a more robust clean energy competitor. This paper examines the present state of CCUS and the challenges to widespread deployment in the energy sector. It explores the policy and technology environment for coal-fired power generation and CCUS for energy and industrial uses. It offers an array of actions policymakers and regulators can use to encourage CCUS adoption to extend the life of existing coal-fired power plants while drastically cutting carbon dioxide emissions, illuminating how the coal plant of the future could look.
