[BBC] Hydrogen made by enzyme is faster and cheaper - Page 2

post #11 of 77
Energy is a good example of why corporate politics is hurting our society. These breakthroughs, while important, should have been made years ago, however the oil companies have invested millions of dollars lobbying against exactly these sorts of discoveries. Good find though, I'm glad to see that the science community is making some progress.

Separating salt from solution is not a reaction.

CMON GUYS HIGH SCHOOL CHEMISTRY
Lol he wasn't talking about creating energy, he was talking about desalination.

Quite cool stuff.
We need this to create hydrogen from water fast and cheaply to use in hydrogen fuel cells.
This is the future.

Seems promising tho. Hydrogen as fuel, and the subproduct is water? now that is clean fuel.

Problem with hydrogen: fuel density.

Even compared to batteries, hydrogen just doesn't have the energy density to be a viable fuel option right now. If someone can figure out how to make it possible, awesome. But until they do, fuel cell cars aren't going anywhere [pun intended]

Trees. You realize that hydrogen comes from water right? That's what he was talking about lol. Desalanation isn't a chemical reaction, which is what enzymes do.

The problem isn't getting hydrogen gas. It's storing it; that's the problem. Currently, there isn't any sustainable means of storing it in tanks. From what I calculated (if I did this right), 100Kmol/s is about 1g/min which isn't that much. One more thing, water isn't the only way to extract hydrogen, methane gas particularly in the midwest is quite abundant. Burning it will release a 3:1 ratio.

Yep, that's why we shouldn't use hydrogen. It's flammable and explosive, unlike our incredibly stable petroleum. You sure are witty.

No, the problem is definitely getting hydrogen. Currently, it takes more energy to create hydrogen than it does actually burning the stuff. The same can be said for ethanol/biofuel. Once we figure out a way to sustainably harvest hydrogen from whatever cheaply without using energy, the hard part is over.

We have had people experiment with hydrogen in the past. Search the name Stanley Meyer, he built a hydrogen powered dune buggie that ran off pure hydrogen. It was much more powerful than any fossil fueled vehicle. He was murdered by poisoning back in 98', probably by the energy companies. He had a great invention though, instead of selling his creation he was going to give it away.

Tesla was a great inventor as well. He built an electric powered car that didn't require recharging.

Meyer said for every gallon of pure hydrogen it would take 20,000 gallons of fossil fuel to equal the power of the hydrogen.
