DOE research touches virtually every aspect of energy resources,
production, conversion, efficiency, and waste mitigation. A central goal is to
find ways to minimize the use of fossil fuels and maximize the use and
efficiency of renewable energy sources such as water; the sun; wind; ocean
waves, tides, and thermal energy; the earth’s heat; and biomass resources for
biofuels (www.eere.energy.gov). DOE also
seeks to generate, transmit, and use electricity and other energy sources much
more efficiently and with higher capacity; explore the use of hydrogen in fuel
and energy applications; develop clean coal technologies; optimize nuclear
energy plants, and harness fusion as a completely new, economically and
environmentally attractive energy source. (http://science.energy.gov/fes/

X-rays from NSLS reveal fuel cells in action
Wouldn't it be great to have a magical "energy box" that could convert a wide array of fuels to electricity with high efficiency and lower emissions? Solid oxide fuel cells show significant promise. But these solid-state energy-conversion devices are made of complex materials and they require specific conditions for optimal operation -- high temperatures, variable pressures, and electrical polarization.
