Subsequently, the exergy of proven coal reserves is calculated, using the figures
of WEC (2010). The proven reserves data for each nation are categorised into: 1)
anthracite and bituminous, 2) subbituminous and 3) lignite. It is assumed that only
hard coal 7 coming from the U.S. is in the form of anthracite because the conversion
factors reported by IEA (2007) indicate that U.S. coal has the highest heating
capacity.
The exergy values shown in Table 11.11, are generated from R.E. III, which is
the most commonly used for fuel calculations (Lozano and Valero, 1988).

(2010). Values stipulated are in million tonnes if not otherwise specified

7 Hard coal is another name given to anthracite and bituminous, as opposed to brown coal, which
is given to subbituminous and lignite.
