Sapphire Energy has developed its West Mesa Industrial Park plant into an algae field research and development center, said Bryn Davis, New Mexico operations manager. The algae “green crude oil” production company is constructing a half-acre greenhouse that will be covered with plastic to allow sunlight to stimulate the algae. “We’ll be able to grow algae in small containers with a controlled environment,” Davis said. “This will allow us to experiment faster on a small scale at our field test site before moving outside to larger ponds.”
The process will be a blend of engineering, science and agriculture in one operation. The company has acquired 10 acres at the West Mesa Industrial Park and has the option to purchase up to 100 more acres. Sapphire has also acquired 1,000 acres in Luna County to produce green crude.
The company and contractors are reviewing designs to construct water raceways to cover from 100 to 300 acres underwater to produce algae, Davis said. Many researchers have good ideas, but they have to develop them to make them work, he said. Algae are microorganisms that use sunlight and photosynthesis to produce green crude oil.
The Luna County site will not compete with agriculture. The land is marginal and the water is brackish, but there is ample sunlight, the Sapphire information report emphasized. Producing algae green crude oil does not depend on crops or valuable farmland. It can deliver 19 to 100 times more energy per acre than field crop biofuels. The Sapphire goal is to produce green crude as a “drop-in fuel” transportation replacement fuel can be used as gasoline, diesel or jet fuel.
“There’s no need to change the energy infrastructure or equipment,” Davis said. “The fuel that we’re producing is indistinguishable from the fuels that we’re producing now.” Sapphire plans to start extracting green crude by the summer of 2012.
Algae raceways are constructed with concrete blocks that are lined with plastic. Small paddle wheels circulate the water to keep the algae from settling. Green crude is the oil that algae produce by combining sunlight and carbon dioxide from the atmosphere, which can be refined into fuel, gasoline, jet fuel and diesel.
Sapphire has compiled a list titled “Why Does Energy Matter So Much?” that discusses countries energy consumption. Driven primarily by transportation fuel consumption, the United States’ demand for crude oil exceeds its supply, forcing the nation to rely on imports to meet the domestic supply deficit. As the U.S. produces renewable fuels, it provides energy security and reduces carbon dioxide emissions. Algae biomass is among the renewable energy leaders.
Electric, thermal and transportation energy use in the U.S. emit about 5,890 million tons of carbon dioxide per year, and liquid fuel and coal emit 4,715 million tons per year.
