1.   Another goal is to help build a network of refueling stations, to make it easier for other fleets to run on natural gas and methanol.

2.   California CNG has built just one natural gas refueling station, in Glendale, Calif.

3.   Moreover, there are only six refueling stations for alternative fuels in the Phoenix area, and none in the rest of the state, she said.

4.   Most of the Taurus cars running on methanol, which is made from natural gas, are sold in California, where refueling stations are most common.

5.   Officials closed Opa-locka West Airport and used it as a refueling station for police helicopters.

6.   That has limited the use of natural gas -- which is cheaper than gasoline -- largely to company fleets whose owners can afford their own refueling stations.

7.   But there are only a handful of refueling stations in the world where drivers can get hydrogen, and it is expensive to produce, store and transport.

8.   Co. and Plug Power Inc. said they will collaborate on research into home-based hydrogen vehicle refueling stations.

9.   The Bush administration launched a partnership with domestic automakers in January to develop a system of hydrogen refueling stations and spur the growth of hydrogen fuel cells.

10.   The refueling stations they will work on will provide heat, hot water and electricity to a home while also producing hydrogen for a fuel cell vehicle.
