$100 Million Funding for Algae Biofuels Plant

Friday, December 11th, 2009

By David L. Brown

A $50 million federal grant has been awarded to Sapphire Energy of San Diego, CA, for a revolutionary bio-fuels plant to be built in New Mexico. The announcement was made by Energy Secretary Steven Chu, whose department issued the grant under the economic recovery program. At the same time Agriculture Secretary Tom Vilsack announced the USDA would further back the program with loan guarantees up to $54.5 million.

The company is pioneering what it calls “green crude oil,” created from renewable algae. The “green crude” will be used to make biodiesel and jet fuel. The company has already demonstrated the concept with research facilities at Las Cruces, NM and Portales, NM. The process has been demonstrated with several airliner test flights powered by fuel made by the company, and experiments are underway to prove the ability of algae-oil to be used to make gasoline.

In a second stage the oils will be processed to produce fuels. Algae, pictured at left, not only grows fast (think kudzu here), but naturally contains a high percentage of oils.

According to Sapphire CEO the project will create as many as 750 direct and indirect jobs in New Mexico during construction, and 30-40 full-time positions after the plant is opened. Construction is expected to begin next year.

Sapphire claims that the new energy model, which uses water, carbon dioxide and sunlight to grow the algae, will be carbon neutral and produce fuels identical to those made from fossil fuels. It does not require large inputs of water and energy, nor does it rely on agricultural crops as is the case with some other alternative fuel processes such as those used to produce ethanol from corn and biodiesel from soybeans.

New Mexico Senator Tom Udall hailed the project, saying it “will decrease our dependence on foreign oil, reduce our carbon footprint, and create jobs for hardworking New Mexicans.”

Algae offers one of the best sources for bio-fuels, since it can be grown relatively cheaply in ponds or tanks in areas with lots of sunlight, even deserts as in southern New Mexico. Corn for ethanol, on the other hand, is a farm crop requiring many inputs of land, labor, chemicals and seeds. Using farm crops to replace oil is unsustainable, uneconomical, and just plain foolish.

This is not the only such program in the works. On July 15, 2009, I reported (here) a major investment by oil giant ExxonMobil in an algae energy joint venture with Synthetic Genomics, a company founded by geneticist Craig Venter. ExxonMobil was reported to be putting $600 million into the plan. BP and other companies are also jumping on the algae bandwagon, making this one of the hottest areas in alternative fuel development.

All is not roses in the risky business of alternative energy. On May 13, 2009 it was announced that GreenFuel Technologies was closing down, a victim of the credit crunch. I posted an extensive report on this company’s algae fuel program on October 20, 2006 (here). GreenFuel was a joint venture between Harvard and MIT, and invested millions before falling victim to the economic troubles.

‘Green Revolution’ Pioneer Borlaug R.I.P.

Sunday, September 13th, 2009

By David L. Brown

borlaug-youngNorman Borlaug died yesterday in Dallas, Texas at 95. He was never a celebrity except among the environmentally conscious few, but to us he was a super star. Dr. Borlaug was credited with saving at least a billion and perhaps two billion lives during his lifelong efforts to improve food production through plant breeding and genetics.

Virtually single-handed he created the applied science behind the burst of food production called “The Green Revolution.” During his career he worked on wheat in Mexico and India, rice in China, and other crops in Africa, creating new hybrid varieties to produce significantly more food from the same acres. His work won the Nobel Prize in 1970.

No one  can fault Dr. Borlaug, and yet…

Well, not to be a Grinch, but the Green Revolution is like a lot of things — it has its dark side. Yes, millions and even billions of lives were “saved” from famine through its effects. But the world now has more than 6.6 billion people, more than three times as many as when Dr. Borlaug began his work in the 1940s. And the trouble is that the “Green Revolution” was never a solution to the food requirements of a growing population — it was merely a band-aid, a jury-rigged response that has allowed the world population to continue to climb until today our food production system is once again straining to keep up.

Over the last half century or so, thanks in large part to efforts such as those of Dr. Borlaug, modern industrial agriculture has done a wonderful job of keeping up with population growth. But that highly productive system is based on cheap and plentiful resources, and those very resources are beginning to become less plentiful and more costly. We saw what happened last year when oil prices soared to well over $100 per barrel. Food prices followed, doubling in some cases.

Food and oil are joined at the hip. Without cheap and abundant oil, there will be no cheap and abundant food. According to many reliable sources, we have reached the peak of oil production, and thus, we have reached the peak of food  production. There may be a few years of ups and downs before this fact settles in, but there seems little doubt that the world has exceeded its capacity to feed its people, and the problem will continue to become worse.

There are many ways in which oil plays such a key role in industrial agriculture. Not only does it power the machines, but it is also the means of mining, extracting, pumping, manufacturing, and transporting materials and equipment to the farm, then carrying food to markets around the world. Oil is the feed stock for chemical processes that produce herbicides, insecticides, and other substances critical for top yields. Higher oil prices create more demand for natural gas, which is the source of nitrogen fertilizer.

Here in the U.S. we cannot easily see how serious this problem really is. To the average American, food costs are a relatively small part of our budgets, around 10-15 percent. But consider the situation in the poorest parts of the world, where many survive on one dollar per day or less. For these unfortunates, the “beneficiaries” of the Green Revolution, most of  their scant incomes goes in one way or another to provide them with something to eat. Nearly a billion are undernourished, eating no more than one meal a day if they’re lucky. They’re living on the desperate edge of famine.

And what does it mean for those billion or two billion people at the bottom of this different kind of “food pyramid” when prices go up? Their incomes certainly do not rise accordingly, and if food that once could be obtained on one dollar a day rises to a dollar-fifty, what will become of those who still earn only one dollar? The answer is not an easy one, for their main choices are to sink further into malnutrition, become criminals and steal from others, attempt to immigrate to a place where conditions are better — or to succumb to famine.

There is a well-known principle called the Law of Unintended Consequences, and while some foresaw the bitter end game now beginning to be played out in the world as a result of the burst of agricultural production and resulting explosion of population that it made possible, few actions were taken to prevent the final calamity that was to  follow, the calamity that is even now beginning to occur.

For more about this subject, use the search field at upper right to find other essays on food security. You might particularly wish to read “Money Won’t Solve Looming Famine,” posted on June 2, in which I examined the harsh fact that the world simply can no longer afford to feed its billions.

So  let us pause for a moment in respect for the memory of Dr. Norman Borlaug. He was a good man, he did great things. One might say that he kept a candle burning against the approaching night. But darkness still gathers, and the candle is sputtering out.

Irrational Fear of GM Crops as Famine Looms

The uncontrolled growth of the world’s population lies at the heart of most of our environmental, social, health, agricultural, and political problems. Let’s see, did I leave anything out of that dogmatic statement? Well, sure, because it would be just about as accurate to say that population growth lies at the root of everything that is wrong in the world. Trace each individual problem to its roots and over-population is almost certain to be found lurking there. Many experts believe that human numbers have already surpassed the level that the Earth can support.

When I was born in 1940 there were an estimated 2.3 billion people on the planet. By the time I graduated from college 21 years later, that number had edged up to about 3.08 billion, an addition of about 800 million or about 35 percent. Not too bad, but definitely moving up. So, are things going to be OK?

Well, no. Today, just a few minutes ago in fact, according to estimates by the U.S. Census Bureau’s “Population Clock,” the world’s population stood at 6,523,261,134 people and rising. In fact, those numbers are going up like the altimeter on a Space Shuttle headed for orbit. Factors such as improved medical and public health programs for the Third World and short-term increases in food production through improved crops developed by traditional methods (“the Green Revolution”) have made it possible for human numbers to continue to increase. But for how long can this go on?

Bio-engineering … blessing or curse?

Friday, April 28th, 2006

The subject of genetic engineering is controversial. It has the potential to reduce human suffering and famine, but there is opposition to GM crops from many sources. The acceptance of rejection of GM crops could mean the difference between life and death for literally billions of human beings.
