| Abstract |
Over the past decade, fossil fuels, and particularly
coal, have satisfied the major share of the
incremental growth in primary energy demand. As
coal is a widely dispersed and relatively low-cost
energy resource, it is used extensively around the
world: at present, almost two-thirds of coal demand
in the energy sector is for electricity generation. But
the growing reliance on coal to meet rising demand
for energy presents a major threat to a low-carbon
future. On average, the efficiency of existing coalfired capacity is quite low, at about 33%. This means
that large amounts of coal must be combusted to
produce each unit of electricity. As consumption
rises, so do the levels of both greenhouse and
non-GHG.
Collectively, the large number of coal-fired power
generation units around the world hold potential
to make a substantial contribution to a low-carbon
future. As large point sources of CO2 emissions,
concerted efforts to improve their efficiency can
significantly reduce coal consumption and lower
emissions. But achieving these goals will require
strong policies to encourage the development and
deployment of state-of-the-art technologies. This
roadmap describes how HELE coal technologies2
could contribute to reducing the growing emissions
of CO2 from coal-fired power generation between
now and 2050. In particular, it examines the
potential for combustion of coal under supercritical
and ultra-supercritical conditions, and through the
use of integrated gasification combined cycle. |
