Brazil has been the world’s largest producer of ethanol from sugar cane for nearly three decades and the country has more than 30,000 filling stations that market the biofuel. U.S. Company Amyris Biotechnologies and Brazilian sugar and ethanol group Crystalsev have formed a joint venture to produce and sell the first commercial diesel made from sugar cane instead of oilseeds like soy and canola. In sugar cane, Melo said, “Brazil has the most sustainable and economic raw material,” adding the new diesel will be competitive as long as crude oil remains above $60 a barrel. The first commercial production unit will be built in partnership with one of Brazil’s most advanced sugar and ethanol mills, Santa Elisa — owned by Crystalsev’s major shareholder, Santelisa Vale — in Sao Paulo state. The mill will supply 2 million tonnes of cane a year to the plant, which is expected to come on-line in 2010 and produce 10 million gallons of biodiesel in the first year of operation. Total production within the first five years of operation is expected to reach 1 billion gallons, including the first plant and other units to be built. Amyris is negotiating with Brazil’s National Petroleum Agency to get permission to market the new product. Brazil launched in January a biodiesel program that now mandates a 2 percent blend in all retail diesel. The blend will rise to 3 percent on July 1 and to 5 percent by 2013. Brazil is the world’s largest cane ethanol producer and is forecast to harvest a record cane crop of about 550 million tonnes this season.
Soon setting up a solar power station is to get a lot more user friendly and a new technology could change the solar industry. IKEA changed the rules for furnishing a home. The eSolar power plant is based on mass manufactured components, and designed for rapid construction, uniform modularity, and unlimited scalability. Each eSolar module, though, is designed to generate 33MW of power — enough juice to power 10,000 homes. If you need 330MW, you just buy ten modules and put them together. It’s not exactly flat-pack home furnishings, but it’s the same world-changing idea. Presumably, you’ll need more tools than those little Allen wrenches and nifty fasteners IKEA supplies with its furniture. However, you don’t need the heavy equipment, cranes and trained engineers now required to put traditional thermal power plants together: eSolar has replaced expensive steel, concrete, and brute force with inexpensive computing power and elegant algorithms. This new method of installing a solar power plant minimizes costly civil construction and the use of heavy equipment, dramatically reducing project cost and deployment time. That’s a big claim when you consider that a 33MW modular plant needs 160 acres of land — about 1/4 of a square mile. It’s still a job for a trained construction crew that knows what to do when they open the eSolar box. Inside are many identical towers and thousands of small mirrors — each about a meter square in size — engineered back in eSolar’s manufacturing plant — to essentially snap together. At least that’s how it seems after talking to eSolar executives, who are playing the details very close to the chest. They’re promising to show off a portion of a module at a demonstration facility somewhere in Southern California before the end of this year. eSolar says solar energy that is cheaper than coal is the goal. The company isn’t yet ready to divulge the cost of a module, but claims that right now, its solution is competitive with natural gas, which can produce electricity for 9 cents a kilowatt-hour. Between the rising price of both gas and construction,
