EarthTalk: Hydrogen-fueled Fuel Cell Cars
Dear EarthTalk: Not long ago we were reading a lot about hydrogen’s role in a clean energy future, with cars transitioning from gasoline-powered engines to hydrogen-powered fuel cells. Where does hydrogen fit now in the mix with electric cars now coming on so strong? — Amanda Jenkins, Troy, MI

Please visit alt-nrg.org This design comes to us from an inventor named Darol Mason. Very smart guy. Very efficient design IF it’s built properly. This series will attempt to demystify the steps needed to make one for yourself.

Q&A: How will hydrogen be manufactured and made available for fuel cell powered cars like the GM Sequel?

Question by joem852: How will hydrogen be manufactured and made available for fuel cell powered cars like the GM Sequel?
Would like to know the manufacturing process and energy source – solar, wind. Interested in the associated economics and the timing for the US and world to be able to completely convert from gasoline to hydrogen powered cars.

Best answer:

Answer by Cazort
Hydrogen as a fuel source is created as energy is stored in a fuel cell, like a battery. It is created by electrolysis of water–running an electrical current through water in order to separate it into hydrogen and oxygen. These are then later recombined to release energy. It’s much like a battery.

Conceivably, you could use any electrical power source to create the hydrogen. If you used fossil fuels, it would actually be worse than using them directly, because there is about a 30% efficiency in converting fossil fuels to electricity, but still only about a 40% efficiency in converting hydrogen fuel to energy…so you’d lose a lot and it would be better to just burn the fossil fuels. If you’re powering it from solar, though, it would be cleaner…but less energy efficient.

In terms of long-term energy impact, things like fuel cell powered cars won’t really make much of a difference at all. The big difference comes in reduction of energy uses–lighter vehicles like sedans instead of SUV’s, more fuel-efficient vehicles, people using public transportation like buses and rails more…etc. These things will have a much bigger impact on the environment than just moving over our energy source.

Hydrogen fuel cells have been considered an alternative for a clean source of energy. In a fuel cell, hydrogen?

Question by Jose: Hydrogen fuel cells have been considered an alternative for a clean source of energy. In a fuel cell, hydrogen?
Hydrogen fuel cells have been considered an alternative for a clean source of energy. In a fuel cell, hydrogen reacts with oxygen to produce water, and at the same time, it releases a great deal of energy. Write an essay that addresses the chemical reaction of hydrogen fuel cells, the energy that is available from this reaction, and whether this type of alternative fuel is feasible. Be complete and use examples to support your statements

We are Jane Joyce, Sarah Lever, Clare Sims and Paul Weston from the engineering history educational charity Engineering Timelines. In this movie we explain how a photovoltaic cell works … using only our hands, a pen and paper, and the odd piece of toast! Oh, and there’s a penguin in there too.
