What if Holland Michigan opened an Algae Fuel production facility?
The buzz is out there and Michigan is poised to take action.
The study itself started as an accident when their research into using algaes to control CO2 emissions found that many species of algae actually have very high oil contents (some over 50% by volume) and therefore might be used to produce vegetable-based biofuels instead.
The study then focused on the farming and production of algae on a large scale and used a desert environment as their base. Their findings were remarkable.
The NREL's research showed that in order to produce roughly 141 billion gallons of biodiesel (the amount needed to replace what the Dept. of Energy says the USA uses in carbon-based fuels in one year), that roughly 15,000 square miles of desert would be needed.
Sounds like a lot. Doesn't it? It's not, when you put it into perspective. The Sonora Desert in the southwestern U.S. is 120,000 square miles large. The U.S. currently uses about 450 million acres of land to grow crops, while 15,000 square miles is only about 9.5 million acres.
In other words, the amount of space needed to grow enough algae to replace all of our current petroleum fuel consumption is only about 2% of the total land used to grow the food we eat! Better yet, it's using land that isn't currently being used to grow food, so no displacement occurs.
So is this feasible? Yes, it is. All that's needed are interested parties to invest in and begin researching and growing the algae needed. That's already started to happen. In April of this year, a new plant, built in Texas, went online and began producing algae for biofuel! (See footnote.)
This means the future is bright for algae-based biofuels and is only getting brighter.

Now that we know that, no matter whose numbers you believe, the energy crisis is only going to get worse, the question has to be answered: How hard will it be to replace most or all of our current petroleum fuels with alternatives?
The first step in answering this question is the basis for my post today. There are a lot of numbers out there to choose from, but for our purposes, we'll use the numbers provided by the U.S. Government via the Department of Energy (http://www.eia.doe.gov/cneaf/alternate/page/atftables/afvtrans_c1.xls).
Just counting gasoline and diesel fuel, the United States used 184.3 million gallons of fuel in 2006. That, my friend, is a lot of fuel. Alternative fuels (such as ethanol, hydrogen, etc.) accounted for only another 4.8 million gallons.
Here is the good news: now that algae is a realistic and usable alternative to regular fuel, it is by far the most efficient way to do so. The numbers on our own website prove this. At 20,000 gallons per acre per year, only 9,215 acres are required to replace all of our petroleum-based fuels with renewable algae fuels. That's not very much when you compare with the alternatives.
Best of all, many of the major consumers in the United States are already running engines that are compatible with fuels made from algae, so they wouldn't need to upgrade or make costly replacements!
This is why algae is such a great alternative that needs to be expanded on and used!
The reality is that most biofuels on the market are not very well positioned to replace anything more than a fraction of our current fossil fuel use. Current numbers from the Department of Energy, for instance, show that ethanol only accounts for about 3.5% of our total gasoline usage in the USA. Biodiesel holds a larger market share world-wide, accounting for almost half of Europe's total diesel fuel usage (according to the European Union).
Given these numbers, the future might look bright. The problem is that both standard biodiesel and ethanol require the use of crops that would otherwise be eaten by humans or animals or of croplands that would otherwise be used to grow them. This takes food off our tables.
Some alternatives, like hydrogen, are becoming more and more viable, but it will still be decades before the fuel cells can be made at a cost low enough to make the vehicles they power marketable. Similarly, electric-only vehicles are plagued by their relatively short range because of limitations in battery storage.
This summer, however, marks a huge stepping stone for algae as a production-level biofuel. Despite setbacks due to funding cuts by the Clinton administration of the 1990s, new funding and a renewed interest by large corporations in the energy industry have rekindled algae's possibilities.
Two years ago, not even a handful of companies were experimenting with algae as a fuel source. Now, in 2008, there are dozens. Chevron, Shell, and other large energy companies are teaming with smaller algae experimenters to research and begin production on oil-producing algae. An operational plant in Arizona and another in Texas are already producing on a small scale while new plants in Hawaii, Arizona, Colorado, and other locations are being built right now.
All of this means that within the next decade, algae-based biofuels could be readily available for your purchase at the pump. In fact, it may be available at the airport too. The Defense Advanced Research Projects Agency (DARPA) has teamed with Honeywell to come up with a J-8 jet fuel for use in military aircraft.
So expect to see algae-based biofuels on the market sooner, rather than later. The high price of gasoline in America has at least one up-side: it drives corporations to look for alternatives to polluting fossil fuels!

My favorite is by Jared Bouck, posted at InfoGeek.com (http://inventgeek.com/Projects/photo-bio-reactor/overview.aspx). His is medium-sized and cost about $200 to build, but can be scaled up or down to suit your budget and desires.
The project itself takes about eight hours to complete, though if you're inept with tools and aren't much of a tinkerer, you might want to double that time-frame. The instructions themselves, though, are great and include a lot of titles like “Killing a Tree” (the frame is built of wood) and “Hitting Stuff With a Hammer” (to build the frame to hold the apparatus in place). I prefer the term “Irish toolbox” to hammer, of course.
The highest cost will be in the acrylics needed: both tubes and tube-ends. Once the setup is going, though, Jared points out that there are a lot of things you can do with it other than just watching it suck up CO2 and bubble away oxygen...
Fish aquarium enthusiasts (especially salt water types) will be more than happy to siphon off your excess algae to feed to their little swimming buddies – and trust me, you'll need to get rid of some algae sooner rather than later, this stuff grows FAST.
So if you've got some time on your hands and want to try building your own algae photo generator, get out your tools, load up Jared's instructions, and go to work!

Most of these biofuel sources use existing food crops (called “feedstock” in the industry) to create fuels. In other words, they remove these feedstocks from the grocery shelves in favor of making fuels out of them. In the case of corn alone, this has meant a marked increase in the price of corn in world markets. It means less corn on the dinner table. Corn is a staple food in this country and is not easily replaced as such. Soy, on the other hand, is a “background” feedstock used as filler in animal feeds, vegetable oils, and more.
In addition, using any food as an alternative fuel means that the crop lands used to grow those foods are not growing them for human or animal consumption, but instead for the consumption of your automobile. This takes food off your grocery shelves. Many farmers are finding it more profitable to grow for the fuel market than for the food market, especially with all the federal government subsidies being given for doing so, and are therefore growing less and less food for us to eat. Not good.
Algae, on the other hand, is not often used for anything more than supplements to diets and are not grown in regular farm lands used to grow most foodstuffs. Algae, instead, grows in swamps and other areas where food production is not common. This makes it a great choice in that algae does not remove any of the aspects of our normal food production from the markets, thus creating a new market for growers instead of replacing current markets.
In a later post, we'll look at harder numbers regarding this phenomenon.
