Hydrogen has been on my mind for about 4 years now, as I put together a venture capital forum for the National Hydrogen Association in 2003 to help support emerging technologies and companies in the Hydrogen energy space. The conclusion I came to is that Hydrogen is currently another form of fossil fuel, since a large percentage of the current feedstock of hydrogen made by major corporations is fossil fuel in the form of natural gas.
The core idea is to produce sustainable hydrogen. Simply, the process of making hydrogen out of natural gas or other fossil fuel has a carbon byproduct. It can be sequestered, but that is a cost that is sometimes not considered, until now with carbon credits... yet that is another story for another day.
Long story short, you want to produce sustainable hydrogen - ideally by electrolyzing water to produce hydrogen "H2" from water "H2O."
According to the following article, scientists cited below have found a way to send sound waves through salt water and produce energy by literally burning the Hydrogen that is released from the water.
I'd love to learn the chemistry behind this one! More to follow....
Here's the article:
"Radio Frequencies Help Burn Salt Water
ERIE, Pa. - An Erie cancer researcher has found a way to burn salt water, a novel invention that is being touted by one chemist as the "most remarkable" water science discovery in a century.
John Kanzius happened upon the discovery accidentally when he tried to desalinate seawater with a radio-frequency generator he developed to treat cancer. He discovered that as long as the salt water was exposed to the radio frequencies, it would burn.
The discovery has scientists excited by the prospect of using salt water, the most abundant resource on earth, as a fuel.
Rustum Roy, a Penn State University chemist, has held demonstrations at his State College lab to confirm his own observations.
The radio frequencies act to weaken the bonds between the elements that make up salt water, releasing the hydrogen, Roy said. Once ignited, the hydrogen will burn as long as it is exposed to the frequencies, he said.
The discovery is "the most remarkable in water science in 100 years," Roy said.
"This is the most abundant element in the world. It is everywhere," Roy said. "Seeing it burn gives me the chills."
Roy will meet this week with officials from the Department of Energy and the Department of Defense to try to obtain research funding.
The scientists want to find out whether the energy output from the burning hydrogen — which reached a heat of more than 3,000 degrees Fahrenheit — would be enough to power a car or other heavy machinery.
"We will get our ideas together and check this out and see where it leads," Roy said. "The potential is huge."
