Pond scum to the rescue?
Denver Post ^ | 07/05/2008 | unknown

Posted on 07/05/2008 7:54:19 AM PDT by ovrtaxt

Remember the optimist's creed, "If life gives you lemons, make them into lemonade"?

Well, ConocoPhillips and the Colorado Center for Biorefining and Biofuels are trying to do one better in a new, $5 million research partnership:

"If life gives you pond scum, turn it into alternative fuels. And while you're at it, fight global warming."

OK, trying to cram two good ideas into one slogan may make it too long for bumper stickers. But it is a classic example of the creative thinking that promises to reshape Colorado's future while creating jobs in the new energy economy.

Making fuels from pond scum isn't a new idea. Nature thought of it millions of years ago when it covered layers of algae and other organic matter with millions of tons of rock to produce today's deposits of oil and natural gas. But soaring energy prices have encouraged researchers to speed up that natural process.

Algae is very efficient at converting sunlight into oil, so much so that researchers say algae can produce more oil in an area the size of a two-car garage than an entire acre of soybeans. Best of all, in water-short regions like Colorado, algae fuels don't compete for scarce fresh water resources but can use seawater or wastewater to make biodiesel, biogasoline and other biofuels.

That means algae can be grown in areas where human food can't be grown, according to Al Weimer, executive director of the center. And how's this for a kicker: carbon dioxide from power-plant emissions can be used as a feedstock for the algae.

So instead of spewing carbon dioxide into the atmosphere from a coal or natural-gas fired power plant, we can recycle that greenhouse gas into algae-based fuels for cars and trucks — fighting global warming and the OPEC oil cartel at one stroke.

Maybe it's time to stop using "pond scum" as an insult and start using it to save our wallets and our planet.

Well, naturally the developers are talking it up, and maybe there’s some truth in it, although collecting all that algae and transporting it to a refinery may be harder than one would think.

You need to research that website a little more. They have a prototype manufacturing plant that actually grows the algae in plastic tubing vertically in greenhouses. They grow and manufacture the algae and extract the oil in one process.

There's an excellent video on the site that shows and explains the process.

Finally! A truly wonderful use for democrats.

In reality, methinks the corn and soybean lobbies aren’t going to take to being scummed. So to speak.

Check your "fishy" math. Worldwide crude oil demand is 86.6 million barrels a day.

In the U.S., we consume about 180 billion gallons of diesel and gasoline. If we shifted all that to biodiesel (over a period of years, obviously), we could produce the necessary fuel from algae on about 10 million acres.

You accidentally omitted the next two words: "and wastewater." Also, note the sentence said "water-short regions like Colorado," Another "water-short" region might be...California, where seawater is available.

What they do is to Drill to the salt water layer and there you go. Ignore any shale deposits and any oil.

Three cheers! I’ve been hoping that somebody would do just this, because it has the promise of everything good about alternative fuels and none of the drawbacks.

The algae is as much as 50% vegetable oil, readily converted to biodiesel with the addition of ethanol and a catalyst. With little modification it can run in an ordinary diesel engine.

And when you pump waste CO2 and Nitrous Oxides (NOx) through it, algae grows extremely fast. Otherwise, recycled effluent or even salt water and sunlight is about all that is needed.

Unlike using plants like corn, which is terribly wasteful and stupid, algae grows almost year around, south of the Mason-Dixon line, and even in cold, pale Massachusetts sunlight, with these waste gases, it grows very well.

It doesn’t need to be on farmland, and is relatively scalable, so once the technology is perfected, even farms can use algae to make both the diesel fuel they use and animal fodder with what is left over.

And diesel engines themselves are very efficient and are scalable, from cars and trucks, to trains and ships. One heck of a lot better than using stupid hybrid or ethanol vehicles.

Biodiesel mixes well with petroleum diesel. At 20%, it can be used in an unmodified engine. And if you use 99% biodiesel with 1% petroleum diesel, the petroleum diesel keeps unwanted bacteria from spoiling your biodiesel.

Diesel cars are very powerful, accelerate quickly, and are just as good or better than gasoline cars. So to hell with driving sucky little matchbox cars just to make liberal wimps happy. You can drive a diesel powered SUV if you like.

And algae is as renewable a resource as it comes. The more we produce, the less petroleum we consume, and the more self-sufficient we become. At a magic point, we will be able to turn off imports altogether.

If the damn Democrats will just get out of the way and let adults run things.

Soybeans produce about a barrel of biodiesel per acre. And that is if everything goes right, as in no floods or droughts. Too much cropland would have to be tied up to make a difference if all you get for a year’s worth of hard farming is 40 something gallons of fuel per acre. It would be better to drill, go nuclear, and pursue biofuel options that did not require so much farmland, like algae and crops like switchgrass that could be grown in marginal areas like freeway medians or other areas not suitable for farming. There may not be one magic bullet to solve all of our energy problems, but several good options put together would be a better answer than going all out with corn ethanol.

I mean million, sorry and it was worldwide.

>”we could produce the necessary fuel from algae on about 10 million acres”

I still don’t think it work. We have many ‘novel’ ideas with no real results. I hope I am wrong since 10 million acres is nothing in US

“If there is an upside to high energy prices it is that the ingenuity of the American people gets put on display.

The thought of Arab oil billionaires being usurped by algae makes my heart proud.”

They’re just being replaced by a higher life form.

According to optimistic projections a 10,000 gal/acre yield of oil might be possible in the open pond method.
To produce significant amounts of fuel would require several square miles of of open salt water ponds in the desert.
Does anyone really think that vast amounts of water are to magically appear in the desert for these farms?
It sounds like most of these companies are mining for investors.

What part of California would these vast algae farms be located where seawater is readily available?

You could do some in the Temecula/Hemet area...wouldn’t be too hard to get seawater over there. Maybe the Imperial valley, too.

Also, there are some areas of central California that might work.

"...we use close to 100 billion of barrels a day so the biofuel math is fishy"

Actually, your statistic is "fishy" (as in odor). The "Energy Information Agency" gives the total US Petroleum consumption at not quite 21 million barrels per day, with gasoline consumption at slightly over 10 million barrels per day.

Algae is a boondoggle
You will have to dig maintain supply water to thousands of square miles of ponds

Then you have to dry out that algae goop before you get bio diesel from it

I doubt algae has much oil content the way soybeans or sunflower seeds do and you can squeeze cooking oil out of them. Thus are bio diesel sources

I'll bet the algae promoters claim they will bio engineer some kind of oily algae.

read post#36.... I agree

Algae is expensive to grow. Check out the prices for spirulina in the health food stores

About $25/lb minimum most is grown in Hawaii

If you like math, here is some.
A square mile is 640 acres. 10,000 gallons of algae oil/acre/yr. equals 6,400,000 gal. oil/square mi./yr.
To displace just 64 million barrels of imported crude per year, Not per day but per year, would require 420 square miles of land for ponds. Plus an ocean of water.
That is equal to less than four DAYS of oil imports.
420 square miles of ponds, 87-88 trillion gal. of water at least for about 1-2% of our annual usage? That's using optimistic figures too.
Somehow I don't algae will do it.
