W&M harvests algae into biodiesel fuel

Gene Tracy guided a raft ashore at Lake Matoaka. But unlike the colonists who settled this land, his quarry wasn’t food or shelter — it was algae.

The College of William and Mary, in collaboration with industry and other universities, plans to turn the fish-killing algae into biodiesel fuel for cars, airplanes, and just about anything else that guzzles gasoline.

On Thursday, Tracy, a physics professor, along with other university officials and a handful of students, worked to assemble the machine — or flume — tasked with the job.

A rectangle-shaped floating dock with its midsection removed, the flume acts as a channel that will trap nitrogen, phosphorous and other nutrients that form oxygen-deprived dead zones in the lake and Chesapeake Bay watershed.

“Think of it as a rain-gutter-type device,” said Karl Kuschner, the university’s research scientist leading the effort. “We’ll be creating a 40-foot long hole in the water.”

Work aims to re-engineer algae for biodiesel production

A Purdue University researcher will lead a portion of a federally funded effort based at Iowa State University aimed at creating genetically engineered algae for environmentally friendly biodiesel production.

Currently, hydrocarbon fuels such as diesel and gasoline require complex chemical processing to be manufactured and are made primarily from non-renewable fossil fuels, which are being depleted, whereas the single-cell algae use photosynthesis and are renewable resources, said John Morgan, an associate professor of chemical engineering at Purdue.

The Purdue portion of the work focuses on creating algae that produce more lipids, the precursor of biofuels. The algae harness solar energy to make lipids from carbon dioxide in the atmosphere.

“Algae now store some of their carbon as lipids, but not enough to be useful in producing biodiesel,” Morgan said. “We need to genetically engineer them to increase the amount of lipids they accumulate.”

The three-year project is funded with a grant of more than $4 million from U.S. Department of Energy and is led by Martin Spalding, a professor in the Department of Genetics, Development and Cell Biology at Iowa State. About $1 million of the grant, which is part of the American Recovery and Reinvestment Act, is funding Purdue’s portion of the research, which began earlier this year.

“The grant was highly competitive, with only 1 percent of applicants being selected,” said Arvind Varma, Purdue’s R. Games Slayter Distinguished Professor of Chemical Engineering and head of the School of Chemical Engineering. “It’s important work that aims to reduce our reliance on fossil fuels and our carbon footprint.”

The algae are being grown in a “bioreactor” in Morgan’s laboratory in the Forney Hall of Chemical Engineering. Algae carry out photosynthesis using energy from light to convert carbon dioxide into a variety of products, including lipids.

“The carbon dioxide is routed in many directions to produce various products, and we are trying to maximize traffic in the specific pathway that leads to lipid storage,” Morgan said. “We want to maximize the accumulation of lipids, which can then be harvested and turned into biodiesel.”

The Purdue group will create “flux maps” that reveal the speed of reactions along many “metabolic pathways” inside algae, information that should enable researchers to engineer algae to store more lipids.

Other researchers in the project will focus on creating algae that thrive in higher temperatures than natural algae can tolerate. The elevated temperature kills contaminants that hinder algae growth. Another facet of the work will focus on increasing “carbon dioxide assimilation,” the first of many steps leading to lipid storage.

Algae Biofuels Project Goes Commercial Demonstration Scale

CARLSBAD: A ceremony Wednesday morning in the middle of the Pecos Valley marked the beginning of a significant chapter in energy production in New Mexico.

With the snipping of a ribbon, the Center of Excellence for Hazardous Materials Management moved its Algae Biofuels Project from pilot scale to the commercial demonstration level.

Located on the grounds of the New Mexico State University Agriculture Science Center south of Artesia, this phase of the project expects to be in full operation by Sept. 1, producing algae that will be harvested and processed into biodiesel fuel.

The project has the potential to produce 5,000 gallons of oil per acre per year, according to Doug Lynn, executive director of CEHMM.

The center has been conducting applied research in the growth, harvest and extraction of oil from algae to find the most productive species for the production of biofuel.

Local, state and national officials were on hand to mark the project’s progress.

“The money we’ve received from the state has been a major help: the state of New Mexico has recognized that we have to have move to other (nontraditional) energy sources,” said Rep. John Heaton.

“With 5,000 acres in production, it would produce half of the diesel fuel required for (the state of) New Mexico,” said Heaton, or 25 million gallons of biodiesel fuel.

U.S. Rep. Harry Teague praised the impact the project will have on reducing the country’s dependence on foreign oil.

“The work CEHMM will do in commercial demonstration ponds will make huge advances in America’s energy portfolio by reducing dependence on foreign oil,” Teague said. “Algae is the newest biofuel to become credible.”

The project has been a partnership between CEHMM and the U.S. Department of Energy, New Mexico State University, the State of New Mexico’s Energy Innovation Fund and the city of Carlsbad, Lynn noted.

“It’s about energy, but it’s also about the economy and creating jobs,” said Doug Lynn, executive director of CEHMM.

The project will not only provide a fuel source, it will create 165 high-paying, technical jobs in southeast New Mexico, Lynn said.

OriginOil Launches First Mobile Extraction Lab to Potential Customers

MAX ONE will visit algae producers to test their strains, demonstrate effectiveness

Los Angeles, CA May 20, 2010 – OriginOil, Inc. (OOIL), the developer of a breakthrough technology to transform algae, the most promising source of renewable oil, into a true competitor to petroleum, announced today that it recently launched MAX ONE, its first mobile algae extraction laboratory. A private party of investors and supporters celebrated the unveiling at the company’s headquarters in Los Angeles.

The trailer-based system will visit algae producing companies in the US to demonstrate how OriginOil’s Single Step Extraction™ process can help them harvest their algae efficiently and cost-effectively. The system is capable of extracting oil from algae at a rate of five gallons per minute, enough to demonstrate feasibility to potential customers.

“Algae can’t succeed as a biofuel without an economical and energy-efficient way to harvest it,” said Riggs Eckelberry, CEO of OriginOil. “That’s why algae companies are eager to test our process as soon as possible. Now we can pull up in the trailer, process their algae, and analyze it for them on the spot.”

MAX ONE was launched on May 17th in front of an audience of invited investors and supporters who toured the mobile system and applauded the OriginOil technology team. Photos and video of the unveiling can be found on the MAX One event page.

This is more than just a strategy to sell more extraction systems, said Eckelberry. “Every algae strain out there has its own extraction profile, and there are thousands of strains,” he said. “This is a great chance to document all the different strains which will help us roll out through partners worldwide.”

While it is currently working with pioneering producers, OriginOil plans to work in the future through country and regional partners, as well as specialized manufacturers and service organizations worldwide.

On May 18th, Eckelberry participated in an industry panel at the sold-out Algae World Summit, a conference that is focused on the algae value chain and which OriginOil helped to create. He reported on the launch of MAX ONE and on the effort to document algae strains. He called for closer industry collaboration, focusing less on the differences between companies than on their shared need to get algae production scaled up quickly to meet fast-expanding demand.

Electronic Waste Produces Algae for Biofuel

When you think of recycling electronics, no doubt you imagine the old PC or mobile phone being disassembled, and it’s metal and plastic parts melted down to be repurposed. But for some people, it means reusing the parts to grow algae.

Students at the University of Illinois at Urbana-Champaign created Bio-Grow, a device made from various computer parts that serves as a reservoir to cultivate algae.

The algae can then be used in biodiesel production, which could potentially replace petroleum in the futures.

“If someone had one of these in their homes, they would cultivate algae and extract it,” said team member and undergraduate student Megan Kenney. “Then they could take it into a gas company that was set up with an oil filtration facility and get credit off their gas.”

Kenney, along with undergraduate students Timothy Harvey, Elliot Reese and Mark Schnitzer, and graduate student Saeidreza Shiftehfar was focused on finding a way to be green, and ended up winning second place in the International Electronic Waste Competition at the University of Illinois at Urbana-Champaign with their design.

“The whole point of our project was two different concepts,” Schnitzer said. “To use electronic waste and to solve a green issue in the world.”

Which is why the team chose to use old electronics to build the device called an algae bioreactor. It encourages photosynthesis, the chemical reaction that happens in plants, which uses sunlight to convert carbon dioxide into sugar.
