Much has
been said about clean coal, and how it is a “wave of the future.” Clean coal
refers to reducing or neutralizing greenhouse gas emissions at the burn point,
but regardless of China’s continuing commitment to coal-powered electrical
plants, the United States has a natural gas glut and increasingly cost-competitive
wind and solar power. As well, mountaintop leveling, destructive chemical
processing, and byproduct disposal challenges continue to complicate any solutions
that billion-dollar U.S. projects such as the recently canceled FutureGen might
have produced.
In
FutureGen, oxy-combustion would have been used in combination with carbon
storage to capture at least 90 percent of carbon emissions. Oxy-combustion
refers to burning coal with a mix of oxygen and carbon dioxide instead of just ambient
air. The United States has identified this approach as the least-cost approach to cleaning up existing coal-fired facilities
and capturing CO2 for geologic storage. But the continued use of
coal in any form is the central problem as its cost effectiveness continues to
decline.
Coal companies continue to go out of business, but
they are not going alone. One industry, sometimes overlooked, that they are negatively
impacting is coal transport. With nearly 90 gigawatts of U.S. coal-fired
capacity (33 percent of the present total) now scheduled to be retired by 2020
and a 35 percent reduction in coal prices since 2012—plus four major coal
company bankruptcies in 2015 alone—industries such as coal barge transport (handling
20 percent of the total) will continue to be dramatically affected by this
shift.
Future Impact
The process here is a reversal of the economic
development multiplier dynamic, which measures the positive impact of new jobs
on regional communities. While water transport reductions largely impact inland
waterway regions, systemic change is seldom confined, but cascades outwards,
often producing unexpected negative impacts at the same time that industries
such as renewable power grow. But renewables need only to transport their
resulting electricity, which is in a major paradigm shift from coal—an industry
that has been a major part of energy production for well over a century.
