Air pollution perceptions and their impacts on the coal industry
P Lloyd
Perceptions of disaster caused by burning fossil fuels have reached
such a pitch that they seriously threaten the very future of the
industry. Coal is a dirty word. A leader in Business Day (January 19
2009) claimed ‘There is no disputing that renewable and nonpolluting
energy sources are preferable to the country—the true cost
of so-called cheap coal-fired power stations is neither reflected nor
accounted for by Eskom—the true and immediate but
unacknowledged cost of continued coal mining is apparent in the
catastrophic level of acidification from mining runoff of all
significant natural water resources in the country—and their waters
have been rendered unfit for human consumption. Air quality is in a
similar state with—increases in pulmonary disease causing
workforce absenteeism and compromised childhood development,
among many other health problems recorded in areas polluted by
coal mining.’ The upshot is that our latest coal-fired power station,
Kusile, is being required to use flue gas desulphurization. The costs
are considerable, and the benefits minimal. Meanwhile, exports are
being threatened by EU directives and an assumption that South
African coal gives off excessive quantities of SOx and NOx when
burned. The industry needs to arm itself with clear responses to
these and similar misconceptions, and to communicate those
responses loudly and clearly, if it is to survive.br>
