Navy Taps Solazyme for Bioengineered Algae Fuel
South San Francisco (October 29, 2010) — The forest green algae bubbling in a stainless steel fermenting tank in a suburban warehouse may look like primordial pond scum, but it is a promising new source of domestically produced fuels being tested on the nation’s jets and warships.
In a laboratory just a few steps away from the warehouse, white-coated scientists for a company called Solazyme are changing the genetic makeup of algae to construct a new generation of fuels.
These “bioengineered” algae are placed into tanks, where they get fat on sugar beets, switch grass or a host of other plants. The sun’s energy, which is stored in the plants, is transformed by the hungry algae into oil, which can be refined into jet fuel, bio-diesel, cooking oil or even cosmetics.
While it may sound far-fetched, the US Navy in September ordered more than 150,000 gallons of ship and jet fuel from Solazyme, and the company received a $21.8 million grant from the US Department of Energy last year to build a new refinery in Riverside, Penn., to help push production to commercial levels.
“Most of the planet is producing some kind of plant matter, even in the oceans,” said Jonathan Wolfson, the CEO and co-founder of Solazyme. “(Our) unique microbial conversion technology process allows algae to produce oil in standard industrial fermentation facilities quickly, efficiently and at commercial scale.”
The US military hopes to run 50 percent of its fleet on a mixture of renewable fuels and nuclear power by 2020. As part of this drive, the Department of Defense has been investing in companies like Solazyme to help jump-start the young industry.
The military as a whole uses more than 90 percent of the energy consumed by the federal government, officials said. The federal government uses about 2 percent of the energy consumed by the United States.
The US Navy has already tested Solazyme’s algae fuels on part of its fleet, with promising results, and plans to have its entire non-nuclear fleet tested by the end of 2012.
Focusing on making fuels for the military was an easy choice for Solazyme – the biofuels market for passenger cars has taken a backseat to electric vehicles as the focus of the future consumer market.
However, billions of dollars of military aircraft and ships will not be replaced anytime soon, so finding a cleaner, domestically produced source of fuel compatible with the current generation of equipment is the best way to decrease reliance on foreign sources of oil.
“These alternative fuels provide some strategic advantages,” said Tom Hicks, deputy assistant secretary of the Navy for energy.
“We purchase fuels today from some parts of the world that are not very friendly to the US Having sources to replace those unfriendly fuel barrels with domestically grown fuel barrels is (important),” he said.
Fuels made from algae oil burn cleaner than fossil fuels and require no drilling to acquire, which means fewer greenhouse gas emissions from the beginning to the end of the fuel’s life cycle. Wolfson said Solazyme’s diesel fuels can reduce greenhouse gas emissions by more than 85 percent versus petroleum diesel, when you take into account the drilling, shipping and refining required in traditional fuel.
Currently, only about 1 percent of the fuels used by the Navy would be considered renewable by most standards. Sixteen percent of the Navy’s energy and fuel needs are achieved through nuclear power, with the rest from traditional sources.
For the Navy to achieve its 50 percent goals alone, production of algae and other renewable fuels will have to increase exponentially. Hicks said the Navy will need 8 million barrels of renewable fuels in 2020 to achieve its goals.
