What issues will affect the future of energy? Let an EPRI* expert fill you in. *Electric Power Research Institute is one of the nation's leading energy industry think tanks.

Transcript: Hydrogen

The perfect energy system of the future would be hydrogen and electricity. Electricity is completely clean at the point of use, It's extraordinarily precise -- enough to run electrons. You can't run a computer on a lump of coal or a gas flame. You need something as precise as electricity. Hydrogen would be the ideal source for generating that electricity. And that conversion technology's coming along, the using technology's taking place right now, it's how do you get the hydrogen? So that's the hurdle we have to get over in the future. But the hydrogen electricity system is where we'll end up 150-200 years from now. Whether we can get there sooner is really the challenge. And I think we need to get there sooner because of the environmental issues. We've got the planet to consider and we are sending greenhouse gases out and we don't know exactly how it will manifest itself, but it will have an environmental impact one way or the other.
