A Canadian research team is attempting to leap-frog typical Lithium Ion batteries by focusing on Lithium-Sulfur battery technology. This technology has the opportunity to provide three times the energy density of Lithium Ion according to their results, meaning a battery of the same size could store three times as much energy.

GE plans to open a Sodium-Metal Halide battery plant in upstate New York for the rail, marine, mining, telecommunications and utility sectors. GE says that facility will produce approximately 10 million sodium-metal halide cells each year (900 MWh of energy storage) and that they will likely be used in GE's hybrid locomotive, set to be commercialized in 2010.

There are now ten of these hydrogen fuel cell buses in use in Europe. The hydrogen fuel cell/battery hybrids make it 200 km (124 miles) on one fill of hydrogen. The buses also take advantage of combined heat and power (CHP), using waste heat from the fuel cell to warm the bus in cool temperatures.
