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.

Sounds great, except that a lot of land is needed to grow all that algae.

No land or fresh water is needed. Algae floats and and is one of the few plants that grows well in the open ocean. And many things eat it so there are several options for a two or three stage harvesting process. 100% efficiency is not needed. 5% efficiency would yield all the transportation fuel we need.

"Good luck processing that wet goopy slimy algae in petro byproducts"

I can promise you that chemical engineers routinely process worse matrices every day (I used to work for "le Giant chemical company", and had to design instrumentation to monitor a lot of those processes--so I'm well aware of what's possible).

The Klamath system already produces tons of natural algae and the tribes and enviros continuously whine about it. The lakes in the upper basin and the reservoirs and mid Klamath River are ripe for harvest. In fact they already harvest some of it as an antioxidant supplement.

No, you grow the algae right next to the refinery and just pipe it over.

As I said already, I agree with the rest of your post.

Dennis, check the Valcent link at post 3. They’ve beat those problems.

If I had to have a small micro-refinery in my garage and a greenhouse in the back yard, and have fuel for life, I’d take that deal.

The refinery is the hard part. Neat fantasy, though...

He said 1/10th of NM using the open pond system- the vertical system would be much less.

But so what, we have some greenhouses dotted all over the country and local oil is produced and refined in a decentralized manner. Better than having only one or two massive refineries that make great terrorist targets.

Sounds like a plan to me.

The entire state of NM is floating on an inland ocean of salt water, and last time I was there, it seemed that they had their fair share of sunlight.

Well, sunlight and desert.

Actually, sunlight, desert, salt water, and rattlesnakes.

What’s the difficulty with just allowing the algae to grom passively? Sure, piping in CO2 speeds up growth, but in a non-cost effective situation, algae will grow on it’s own with the CO2 just floating around in regular air.

Carbon neutral is carbon neutral. Not that I buy into the whole enviro-lie that carbon is a bad thing, but it will give the doomsayers one less thing to complain about.

This will require lots of energy. More money down a rat hole to get that algae goop free of most of the water that comes with it

Oh. yes, hippies. Some NM denizen was duly impressing me, with how her hippy mother was an artist. I replied, how fascinating, odd coincidence, so is my father. She asked, is he famous? I said, no, he only made 250k last year.

The hippie chick ran away.

I've been to that link and can't figure out what their game plan is. Can you summarize it? 

It seems to me they propose to hang plastic bags of algae out in the desert. Racks and racks of them covering hundreds of square miles. This sounds preposterous. 

Then the stinking algae is taken from the bags and made into petroleum byproducts?

Piping in CO2 is moronic and designed to make the algae to oil scheme sound sexier. A bigger deal. Like it’s a carbon sequestration scheme. Hey, burn coal nearby to make electric and pipe in the CO2 to these racks with algae bags on them. That kind of nonsense

This is really not hard to figure out. Take a biofuel refinery, put up a few greenhouses next door to feed it— instead of trucking loads of corn all over the country, or importing soybeans or other foods.

Look, the bags provide a lot of growable surface area, a shield against contaminant strains of algae, and minimal evaporation. These three problems have been the main gripe against algae as a fuel source.

Also, water and oil don’t mix. It’s easy to skim it off the top.

Why are you so opposed? You have something against technological advancement?

I agree, the algae is going to use up CO2 whether you pipe it in or not. That just seems like a waste of money, unless the accelerated algal growth (and thus, the yield over time) is worth the expense of the infrastructure.

Good luck processing that algae goop with a press. This is your way of getting the water out?

This algae scheme is a bit different but I've read all kinds of claims about how cheap algae was going to be and feed the world's impoverished masses. These claims go back decades yet the price of Spirulina was never brought below $25. You cannot feed impoverished populations at that price

Have you ever eaten algae? I have and I have some spirulina here and have been reading about it for 22 years or more

The bags are silly. Imagine, instead, a pipe of used oil barrels on the bottom, clear plastic on the top. Adjust pipe leanth to life cucly of algae, and flow rate.

Input salt water, algae starters, and emissions from local coal-fired plant at one end.

pull pond scum from other end, and water - feed water bach to front of loop.

squeeze pond scum, allow oil and water to seperate.

Feed water and dry debris back to front of loop.

Process oil.

Repeat.

Inputs - salt water, waste gasses, starter stock.

Output - diesel.
