The Secretary shall pursue a program of research and development with respect to the technologies needed to expand the use of low-rank coals which take into account the unique properties of lignites and sub-bituminous coals, including, but not limited to, the following areas—
(1) high value-added carbon products;
(2) fuel cell applications;
(3) emissions control and combustion efficiencies;
(4) coal water fuels and underground coal gasification;
(5) distillates; and
(6) any other technologies which will assist in the development of niche markets for lignites and sub-bituminous coals.
