Interesting advancement in the creation of hydrogen from water. What is silanol and what are the uses?
Read it here:Abu-Omar's team took a compound based on rhenium, a comparatively rare metal often obtained while mining copper, and added it to the organosilane in the presence of water. Over the course of an hour, the organosilane changed completely into silanol, leaving the water and rhenium catalyst unchanged. But the team also noticed there was a gas bubbling from the mixture.
"It turned out to be pure hydrogen," Abu-Omar said. "The reaction is not only efficient at creating silanol, but it also generates hydrogen at a high rate in proportion to the amount of water."
The team estimates that about 7 gallons each of water and organosilane could combine to produce 6 1/2 pounds of hydrogen, which could power a car for approximately 240 miles.
"The big question is, of course, whether it would be economically viable to create organosilane fuels in the quantities necessary to power a world full of cars," Abu-Omar said. "As of right now, there simply isn't enough demand to make more than small volumes of this liquid, and while it's a relatively easy process, it's not dirt cheap either."
But, Abu-Omar speculated, producing organosilanes in larger quantities would bring the price down, and the byproduct – silanol – also could be recycled or sold to lessen the overall cost.
"On today's chemical market, silanol is even more expensive than organosilanes are, but their value would of course decline as well if there were suddenly millions of gallons of them on the market," he said. "These are the sorts of questions that economists would have to look at, and we have other questions of our own, such as whether these reactions can be carried out on naturally occurring hydrogen sources."
