WHY A HYDROGEN ECONOMY DOESN'T MAKE SENSE, December 11
In a recent study, fuel cell expert Ulf Bossel explains that a hydrogen economy is a wasteful economy. The large amount of energy required to isolate hydrogen from natural compounds (water, natural gas, biomass), package the light gas by compression or liquefaction, transfer the energy carrier to the user, plus the energy lost when it is converted to useful electricity with fuel cells, leaves around 25% for practical use - an unacceptable value to run an economy in a sustainable future. Only niche applications like submarines and spacecraft might use hydrogen.

MILEAGE FROM MEGAWATTS: STUDY FINDS ENOUGH ELECTRIC CAPACITY TO 'FILL UP' PLUG-IN VEHICLES ACROSS MUCH OF THE NATION, December 11
If all the cars and light trucks in the nation switched from oil to electrons, idle capacity in the existing electric power system could generate most of the electricity consumed by plug-in hybrid electric vehicles. A new study for the Department of Energy finds that "off-peak" electricity production and transmission capacity could fuel 84 percent of the country's 220 million vehicles if they were plug-in hybrid electrics.

SUSTAINABLE NUCLEAR ENERGY MOVES A STEP CLOSER, December 11
In future a new generation of nuclear reactors will create energy, while producing virtually no long-lasting nuclear waste, according to research conducted by Wilfred van Rooijen, who will receive his Delft University of Technology (Netherlands) PhD degree based on this research subject on Tuesday, 12 December.
