The promises are great, since fuel cells have the potential to very quickly double the efficiency of cars while significantly reducing airpollution.At the same time, there have been news st

18、ories for decades about the problems associated with petroleum. Everything from oil spills to ozone ( 臭氧)alerts to global warming gets blamed on our dependence on fossil (化石)fuels.These two forces are leading the world toward what is broadly known as the hydrogen economy. If the predictions are true

19、, over the next several decades we will all begin to see an amazing shift away from the fossil fuel economy we have today toward a much cleaner hydrogen future.Problems with the fossil fuel economyWhile fossil fuels have played an important role in getting society to the point it is at today, there

The only byproduct is water. There are also no environmental dangers like oil spills to worry about with hydrogen.The elimination

29、of greenhouse gases If the hydrogen comes from the electrolysis of water, then hydrogen adds no greenhouse gases to the environment. There is a perfect cycle electrolysis produces hydrogen from water, and the hydrogen recombines with oxygen to create water and power in a fuel cell.The elimination of

30、 economic dependence - -The elimination of oil means no dependence on the Middle East and its oil reserves.Distributed production Hydrogen can be produced anywhere that you have electricity and water.

All of that generating capacity will have to be replaced by renewable sources in the hydrogen economy.Right now there are several different ways to create electricity that do not use fossil fuels:Nuclear powerSolar cellsGeothermal powerCo-generationHow do you store and transport the hydrogen?Hyd

48、rogen is a large gas of its kind, and it is not nearly as easy to work with as gasoline. Compressing the gas requires energy, and compressed hydrogen contains far less energy than the same volume of gasoline. However, solutions to the hydrogen storage problem are surfacing.For example, hydrogen can be stored in a solid form in a chemical called sodium borohydride. Once the storage problem is solved and standardized, then a network of hydrogen stations and the transpor
