The Biden administration’s proposals to fight climate change would accelerate what has already been a downward decline of the use of coal for generating electricity.
That would further depress railroad coal traffic, industry observers say.
Rob Godby, an economics professor who is deputy director of the University of Wyoming’s Center for Energy Regulation and Policy, said the Biden proposals would accelerate the decline of coal that has been under way for a decade.
During the past 10 years, railroads have seen their coal traffic fall but “black diamonds” still remained a substantial source of revenue.
In 2020, coal was 12 percent of rail freight volume in the United States, figures from the Association of American Railroads show.
Coal was the single largest commodity that Class 1 railroads carried in 2020 and provided $7 billion in revenue.
Yet the use of coal to generate electricy has fallen from 48 percent of the nation’s power supply in 2008 to less than 20 percent last year.
Most coal mined in the United States is used to generate electricity but is also used in steel making and exported to other nations.
Biden has proposed using tax incentives for renewable energy for another decade while making power grid investments to support greater use of wind and solar power.
Godby said those changes, if implemented, will make it difficult for coal to compete on an economic basis with natural gas and renewable sources of energy.
“The bottom line is if this were to happen, you could say the Powder River Basin would almost entirely be shut down,” Godby said referencing a region in Wyoming and Montana served by BNSF and Union Pacific that produces nearly half of U.S. coal.
Godby said some renewable energy projects provide electricity more cheaply than coal, even without subsidies.
Transportation costs can take up three quarters of the delivered cost of coal to a power plant.
Even if Congress were to reject the Biden plan, Godby said coal is living on borrowed time and he expects demand for it to be a shadow of itself by 2035 when very little of the nation’s power will be generated by burning coal.
Already, coal producers are seeking to sell or shut down mines in the Powder River Basin. Arch Resources plans to close the Coal Creek mine in Wyoming in 2022 and reduce production at Black Thunder Mine, the second-largest U.S. coal mine.
The Biden infrastructure plan has proposed establishing as many as 10 power plant carbon capture demonstration projects.
But Godby said for those to be commercially viable, carbon capture would require technology and cost breakthroughs as well as the development of markets for carbon dioxide use.
