That green pond scum on the backyard pool may be annoying now, but it could someday fuel a jet plane to whisk you away on vacation.

And those lawn clippings? They could be used to convert algae into a mass-produced, economical biofuel to be used in cars, trucks and airplanes.

Molecular biologist Amanda Barry and a team at Los Alamos National Laboratory’s Bio-energy and Biome Sciences group are trying to determine whether one particular strain of algae can be produced at low cost and in short periods of time so that it could economically compete with fossil fuels.

“Algae hold great potential as a source of renewable fuel due to their ability to produce refinery-compatible diesel and jet fuel precursors,” Barry said in an interview last week at the New Mexico Consortium’s lab in Los Alamos.

“We are really trying to examine the unique traits of a particular algae that have the potential to be grown for algae biofuels to see if we can exploit any of these traits to improve growth or improve oil production from algae.”

The consortium is a nonprofit corporation formed by three New Mexico universities to facilitate research and increase cooperation between academia, industry and Los Alamos National Laboratory.

Algae, of which there are many types, already are produced in large quantities in big outdoor ponds. But doing it faster and more cheaply is the trick. And though biofuels, such as ethanol made from corn products, have been produced for a long time, algae could be an improvement — in part, because a wide range of oil products can be extracted from algae.

The long game, Barry said, is finding a new domestic source of renewable biofuels and bioproducts. By doing that, “we reduce our dependence on fossil fuels, enhance the energy independence of the United States, secure energy solutions for clean energy, mitigate the impacts of global energy demand growth, and contribute to job creation in a new domestic industry,” she said.

As a child growing up in the mountains of Northern California, a 20-minute drive from the nearest neighbor, Barry started reading about Marie Curie, the famed French-Polish discoverer of radium and polonium.

She never questioned that she would become a scientist.

Barry acknowledged that she was influenced by women in science and hopes to pass that on.

“I try to be a role model for women and for girls, especially in science, and talk about my own experience so that they see that and have people that they can look up to and hopefully see that it’s possible to do what they want to do,” she said.

Barry, 42, “was always super curious about the natural world.”

She originally was interested in physics, “but I didn’t like being inside all day in an office and working on paper; I wanted to work more with living systems and so I got more into biology.” Barry has worked at LANL for six years.

She said she loves the study of algae because it’s such a diverse organism that we are only beginning to understand.

“There is so much we don’t know about algae and that we can really tap into,” she said.

In her work at the lab, Barry is being assisted by three LANL student researchers: Anna Finck of Las Vegas, N.M., and Jenna Schambach and Sara Lamcaj, both from New Jersey. They were busy last week as they examined algae cultures and counted algae cells to monitor growth.

Schambach said one thing she has learned from the experiments is that the strain of algae they are working with “can utilize different plants” for a food source for growth.

The work so far has been in small containers but is currently being transferred to a larger venue — a greenhouse just down the hall.

“Here at the lab we are mostly working with algae at smaller scales than what would be done outdoors at large facilities and so we are working in flasks,” Barry said. “In the greenhouse we also have some small mini-ponds that mimic what it would be like outdoors at larger scale with little paddle wheels.”

The paddles help give the algae air and keep it moving so light is uniformally distributed.

After algae are harvested from large outdoor tanks it is converted into biocrude oil and can then “be put into the existing refinery system to make biodiesel, gasoline and jet fuel,” Barry said.

In the future, LANL will look for an industrial partner already growing algae outdoors “to work with them to see if this would help their process in actually boosting growth and boosting the products they are looking for,” Barry said.

While algae may be a future superstar in the biofuels research arena, it is not the lone ranger. About 30 people at LANL are engaged in all sorts of biofuel research, which has been going on since 2009, said Babetta Marrone, senior scientist and the lab’s biofuels program manager.
