Nano-graphite may store H2 gas

Some news on the hydrogen storage front...

Graphite films only nanometers or billionths of a meter thick could help store hydrogen in an inexpensive, easily manufactured, lightweight and nontoxic manner, an international team of scientists told UPI's Nano World.

"If -- and that's a very large if -- a practical method for preparing the nanostructures can be found, there is a possibility for large-scale, economical production," said researcher John Tse, a materials scientist at the University of Saskatchewan in Saskatoon.

An effective hydrogen storage method has been a big stumbling block for, for example, hydrogen fueled vehicles, largely because "storing hydrogen often demands extreme cold, heat or pressure, which requires equipment that is heavy, bulky or expensive."

Previous studies had concluded that nano-graphite was a poor storage option and that carbon nanotubes were much better, but that could be wrong.

Tse and colleagues at the Steacie Institute for Molecular Sciences in Ottawa and the Technical University of Dresden in Germany reinvestigated graphite via mathematical models and found the prior studies were incomplete when it came to exploring interactions between carbon and hydrogen on a quantum level.

They found graphite layers spaced slightly less than a nanometer apart can store hydrogen at room temperature and moderate pressures at close to a good weight. So the researchers contend graphite is a better option than carbon nanotubes, because it is far easier and less expensive to prepare. Another good possibility is the use of porous carbon foams.

what about those carbon nanotubes?

Enzyme Production Could Boost Biofuels Production
September 26, 2005

Jupiter, Florida [RenewableEnergyAccess.com] Dyadic International secured a patent on a process that manufactures enzymes in bulk. Enzymes, biodegradable and safe catalysts for chemical processes, could allow farmers to cost effectively and cleanly produce glucose from corn, soy, other carbohydrate and cellulose-rich plants and waste - such as cornstalks, wheat straw and sugarcane bagasse, even paper (cellulose).

"Enzymes can be used to reduce demand for energy and help produce alternatives to petro-based products."

-- Mark Emalfarb, Dyadic's CEO Glucose can then be used to create gasoline substitutes and other products.

Glucose is carbon-based like petroleum and is a base for a many energy-efficient products, including ethanol, a gasoline substitute or additive. Glucose is used to make monomers, polymers, polyesters, and plastics.

"The time has come for America to find its own solutions and lessen its dependence on other countries - while we clean up the environment. The way to do that is to have American farmers become American heroes by helping our nation meet its energy needs inside its own borders," said Mark Emalfarb, Dyadic's CEO. "Enzymes can be used to reduce demand for energy and help produce alternatives to petro-based products."

Dyadic's enzyme products are sold in 50 countries, where they help reduce dependency on fossil fuels, save old-growth forests, reduce energy consumption, improve food products and animal feed without hormones, and reduce pollution. Dyadic enzymes and processes already help the paper and pulp industry safely save energy - successfully reducing pollutants and driving energy costs down by 20-60 percent.

"Our science is sound and its impact on the environment and economies of our planet can be very real, if implemented on grand scale by American industry. With it, we can help manufacturers create clean, cost-efficient fuels and products," said Emalfarb.

I'm all for this one, if it really works and is cost-efficient. Glucose and biological organisms are very advanced and efficient nanotechnology. Let them produce the energy for us...if it is possible that is.

it is not hydrogen, or ethanol, or this, that will make the eventual "miracle" we are all hoping for.....it's all of these combined, with biology and nanotech. The more efficient you become the easier it is to extract energy--in one word: become more efficient.

this simple outsourcing of oil by nuclear, ethanol (could be enzyme created--enzymes lower the energy needed to synthesize building blocks at the nano-level---catalysts), solar cells and windpower...the less demand we will all beg from oil, and according to economics, the lower price we will all have from oil.

All it requires are simple measures but implemented on a grand scale (no more hummers for example). More fuel efficient cars by a slight percentage (from 25-to 32) would almost take off a quarter off our energy needs ( that is because 2/3 of our energy demand in gas comes from cars)----
we could potentially---through efficiency---lower the price of oil to 10 dollars....while use the oil to transform our industry to more and more renewable alternatives.

if we had the money---we could build a huge solar and wind farm in Canada (it would probably take all of Canada) and take care of all our energy needs---but it is not profitable at this point---if we become more efficient--we can use cheap oil to transform our "oil dependent economy" --ironically---to an "oil independet economy or very close to it" slowly--by building a paradoxical "solar and wind farm in all of Canada"--little by little we would demand less oil.

what to do with all that money pouring into NASA to send a giant dinasour to the moon? I mean--this "exploration initiative" is not exactly going to lead mankind into space---that would be the space elevator--which would require a lot less money---

No, pour this money into the "save the frieken country from total destruction initiative" --which would basically not go into crazy research but rather just implement little by little--more efficient cars, houses, etc..outsourcing energy production from the power plants to the houses themselves through power generators (solar, little turbines)whatever--to put off some load from the "mother power plant."

As a first step--our target should be: CARS

all cars should become more efficient---that would be a policy passed by the president that the "save the frieken country from total destruction initiative" would be assigned to accomplish.

every year we set goals--and give subsidies to acheive THESE goals.

How about gasoline from coconut oil?

A few years ago, it was difficult to find synthetic motor oils, and equally difficult to find someone who admitted to using them. Nowadays, however, you can find synthetic motor oils on the shelves of Wal-Mart, and other retailers, and the number of people turning to synthetic motor oils, particularly in light of the recent events affecting fuel prices, has risen greatly.

So why do people use synthetic motor oils rather than sticking with the old petroleum based stand-bys which are admittedly cheaper?

1. Let's start with the cost per quart issue. Synthetic motor oils ARE more expensive at purchase. However, these oils last longer, requiring fewer oil changes. As a synthetic motor oil outlasts several changes of petroleum based lubricants, the ultimate out-of-pocket cost of the lubricant is less. This cost savings becomes even greater if you have someone else change your oil for you rather than doing it yourself!

When you're buying a motorcycle you need to know about bikes, but you also need to know about how to buy a bike, and that has nothing to do with engines and manufacturing. One important detail where a lot of people that purchase motorcycles go wrong is getting the right loan.

You can run your car on water! (Actually Hydrogen) I just recently converted my '94 chevy silverado to run on water. It cost me less than $100 for the parts I needed and it went from getting 14mpg to 33mpg. That's double the mileage for less than it cost me to fill up. There is definitely something to this water for gas technology, It works!

the comment from luis is so awesome. thanks for the great information.

this is definitely the future. lets see how this works out.
