On a planet aspiring to become carbon neutral, the once-stalwart coal power plant is an emerging anachronism. It is true that, in much of the developing world, coal-fired capacity continues to grow. But in every corner of the globe, political and financial pressures are mounting to bury coal in the past.
Researchers in the Netherlands have demonstrated the direct conversion of synthesis gas through a Fischer-Tropsch process to C 2 through C 4 light olefins with selectivity up to 60 wt.% using catalysts that constitute iron nanoparticles (promoted by sulfur plus sodium) homogeneously dispersed on weakly interactive ?-alumina
The process produces a toxic byproduct referred to as black liquor—a primarily liquid mixture of pulping residues (such as lignin and hemicellulose) and inorganic chemicals from the Kraft process (sodium hydroxide and sodium sulfide, for example). tons of black liquor dry solids. Globally over 1.3 Earlier post.)
Others, such as the Coalition, say renewables can’t “keep the lights on” at all and Australia should pursue nuclear energy instead. But a new way to firm up the world’s electricity grids is fast developing: sodium-ion batteries. Sodium-ion batteries are now almost ready to fill the long-term storage gap.

Eagle Picher, in partnership with the Pacific Northwest National Laboratory, will develop a new generation of high energy, low cost planar liquid sodium beta batteries for grid scale electrical power storage applications. Energy Efficient Capture of CO 2 from Coal Flue Gas. DOE grant: $7,200,000). DOE grant: $3,111,693).
Liquid sodium is used as a coolant because it does not slow down neutrons as much as water does. The new breeder reactors in China, meanwhile, are demonstration projects, the second step in a three-step program to develop fast breeder reactors to reduce the country’s dependence on coal.
Improving hydrogen-from-coal technologies, including developing membranes for separation and purification that show the potential, at laboratory scale, to achieve the 2010 technical targets for flux (200 ft 3 /hr/ft 2 ). Analysis of excess and/or waste hydrogen sources.
