Posted on 05/07/2009 5:06:07 PM PDT by decimon
The method, called catalytic hydrothermal gasification, creates natural gas out of algae - more quickly, more efficiently and at higher yields than other biofuel processes. Genifuel expects the process also requires less capital investment. The license agreement moves this technology for renewable energy production a step closer to commercial reality. Battelle operates PNNL for DOE.
"Algae and other aquatic biomass hold significant promise for our country's ability to produce renewable energy domestically," said Genifuel President Jim Oyler. "At Genifuel we have developed efficient growth and harvesting techniques for the aquatic biomass. With this gasification process, we can convert the biomass to a clean fuel that is almost completely carbon-neutral."

Slime gas ping.
“That doesn’t cost enough money. Cover it up.”
-Probably what 0bama is saying about his green policies.
If it’s privately funded and means we buy less from the people who hate us, I’m for it.
You know, they also say if you drill a hole in the ground you can find VAST pressurized pockets of it trapped it the strata. Oh well, it’s prob just another urban legend,,,
I'll drink to that.
It’s GREAT!! Think of a Crown Victoria, with the fuel tank taking up most of the trunk. Having a little less than spectacular acceleration, and with 90 or 100 miles range in the city!!
A long time ago, in Canada. Ran fine.
Add GTL process to this and you’d have a very clean diesel type fuel.
I believe that I had a boss once who had a propane powered drag car. Propane has a high octane rating and the engine can be built with a high compression ratio. Turbo or supercharging shouldx get you reasonable performance.
Propane gives a bigger "blowed up real good" than natural gas so I'd guess it's less safe than gasoline in a motor vehicle.
What it’s actually super good, at is firing power plants to generate electricity, and for light industrial and home use. It’s clean, and we have more than we can use domestically.
Unfortunately the AlGore crowd hates it too.
Ford used to sell propane cars in Canada. They had pumps at the gas stations.
Sure, my dad had his 1982 Dodge truck converted to run on propane. He had duel 18 gal. gas tanks that came with the truck and a sixty gal. propane tank in the bed. He pulled a house trailer with it. Flip a couple of switches on the dash and you could run on either propane or gas. I sold the truck last year and it was still running good - gas or propane!
There are a lot of propane vehicles on the road right now.
It doesn't get as much power or mileage, the price is a little lower, so it costs about the same per mile as gasoline.
Oh sure, i don’t doubt that. You can build super engines on everything. But we are talking about converting existing passenger engines into running on it. Thats not so good. And dragsters only go 1/4 mile. CNG cars have extremely short range.
Our city bought them for the police in some PC grant program. Within a year they were being used by cops that worked inside schools all day and didnt need any range, and other assorted city workers that didnt drive much except maybe one short trip a day.
Gasoline is actually quite dangerous. Difficult to contain and heavier than air. For safety, I'd go with Diesel.
In a Pinto you'd burn to death. From what I've read of propane explosions, you'd never know it happened.
However, from Paladin2's posts, it looks like propane has been used safely in motor vehicles. Fine with me it it works.
LPG is better than NG for energy density. Some cars were gas/LPG bi-fuel.
I have a question about this story. It says, “efficiently,” but what does that mean? Does that mean it produces natural gas as cheaply as a conventional gas well? What is the cost of this fuel? I agree that every drop of fuel we don’t buy from people who want to kill us is a good thing.
Didn't know that. Didn't know there is that much propane.
Yeah, except when a gasoline leak occurs at a wreck, it dribbles out like water usually. Compressed gas will instantly become a high pressure leak of a gas, not a liquid.
None are THAT safe, but CNG scares a fireman more than a car with gasoline.
Thats kinda how i heard it too. Lots of farmers around with Porpane powered pickups. Cant say ive heard that about CNG so often.
Good question as it always comes back to economics. As with most of these new process announcements, there is a lack of specifics.
Why did you sell it ? ......
There are hundreds of tankers hauling propane all over the country.
RVs use it for heating and cooking. Some as a motor fuel.
You can fill up with propane at many truck stops and RV camps.
At 3000 psi, CNG is like driving around with bombs attached to your vehicle. CNG does rise rather than hang down by the ground. CNG=!LPG. Both LPG and gasoline are kinda nasty too. Ever use gasoline as a campfire starter? Stand way back.
I sold it to a black guy who had had his eyes on the Dodge truck for years. My dad was reluctant to sell it even though he never drove it any more.
The black guy was a Dodge truck enthusiast. It went to a good home. I see him driving it around town all the time.
But you don’t understand, it’s got carbon, arrrrghhhhhhh
It’s a fossil fule....arghhhhhhh. PANIC PANIC PANIC!!!!
Around my way, propane seems to mostly be used for water heaters and gas grills.
I’ll settle for heating homes in winter and natural gas fire power plants.
In western areas, it is extensively used for heating houses.
A lot more than heating oil.
I wonder if I got the motor from a Hover Vac and mount it on a big inner tube from a tractor trailer, and some how mount some solar panels ? would that work ? sort of like a Hover Craft ..... at least the greenie meanies would be happy.....
I have driven a propane-powered dragster...
Pretty frickin’ mean!
It will get shot down because it’s not a food crop. No logic involved, the goobermint is fixated on diverting food crops for biofuel. Thus biofuels will remain boondoggles.
To err is human, but it takes a goobermint bureaucrat to really mess things up.
"Here is our solution to the energy crisis," said Abdur, with a fatuousness I thought you had to go through Yale Law School to acquire. A tricycle rickshaw is energy efficient like a Kuwaiti oil-well fire. The average food intake in Bangladesh is said by the Bangladeshi government to be 2,215 calories a day. One gallon of gasoline provides 125,000 BTUs, which is equivalent to 31,250 calories. In other words, a gallon of gasoline is a box of sugar donuts, a half-dozen twelve-ounce steaks, three six-packs of beer, a pizza, an apple pie, a twenty-piece bucket of Kentucky Fried Chicken, one hundred chocolate chip cookies, a birthday cake, a quart of bourbon, and a Big Mac and fries -- which is more than a rickshaw puller gets in two weeks, if ever. And a gallon of unleaded regular costs about seventy-five cents, before taxes. Try feeding anybody for two weeks on seventy-five cents, even in Dhaka.
