A recent study that contends algae-based biodiesel is no more environmentally friendly than conventional row-crop feedstocks has generated some controversy, as well as quite a few comments. And even the algal-biofuel industry seems to be split on the issue.
As you might remember from my story last week, University of Virginia researchers have concluded that algae’s environmental footprint is larger than other terrestrial crops, and the environmental impact of algal-based biofuels needs to be better studied before major investments in algae production are made.
The Algal Biomass Organization has taken exception with the study with the group’s executive director, Mary Rosenthal, pointing out several concerns about the report:
· Assumptions about algae growth systems. The report uses a first generation, raceway-style pond system as its benchmark. Many leading algae companies abandoned that approach years ago and have a variety of more advanced cultivation systems, some of which are unrelated to the methods the authors sought to assess.
· Assumptions about co-location. By assuming the production facility is not co-located with a large CO2 emitter, calculations for sourcing CO2 are flawed, resulting in a higher attribution of CO2 for algae plants. Most commercial-scale algae projects are being developed alongside major emitters in order to beneficially reuse CO2 that will take the place of equivalent carbon emissions from petroleum fuels.
· Assumptions about water use. The study assumes fresh water and non-potable salt water are equal. A sustainable industrial algae production model uses non-potable, non-agricultural water in the process of making liquid fuels.
While agreeing with ABO’s contentions with the study, Riggs Eckelberry, CEO of algae-biofuel maker Origin Oil, says the research does prove that the old way of turning algae into biodiesel is not a valid method anymore. And it’s not a method his company practices.
“It basically puts a tombstone on those earlier approaches [to algal-biodiesel production].”
Eckelberry says the Virginia study confirms earlier research that OriginOil did that found you need to co-locate algae-growing operations with other CO2 producers, you can’t use vast amounts of land, and non-potable water must be used, among other things. But Eckelberry says the algae industry has done a poor job getting that word out, with his own company’s research all but ignored months ago. He hopes this will serve as a wake-up call for the algae industry’s advocacy group.
“I think they’ve been looking for a focus and some traction as an organization. And from the e-mails I’ve received and forwarded [from the ABO’s Rosenthal], I think they’ve found it.”
Eckelberry says he’s forwarding his information to the ABO in hopes the industry can work together to show that algae-based biofuels are truly the greenest fuels on the planet.

Hutchinson Salt was the first mine of any kind to use B99. Since 2003, the company has used between 17,000 and 30,000 gallons of B99 a year, depending on the demand for salt.
“Given what we know about algae production pilot projects over the past 10 to 15 years, we’ve found that algae’s environmental footprint is larger than other terrestrial crops,” said Andres Clarens, the study’s lead author. “Before we make major investments in algae production, we should really know the environmental impact of this technology.”
Researchers at a school in Philadelphia have figured out how to get more oil from a decidedly non-food source: tobacco leaves.
According to their press release, the group will offer an opportunity of a Ride n’ Drive on January 26 — a test drive of a Chevrolet HHR powered by E85 made from paper waste. The Ride ‘n Drive will allow media, government officials and other VIP guests can to drive the vehicle between 8 a.m. – 4 p.m. Novozymes will make an address to the crowd from 2:35 – 2:45 p.m.
The governor of a state that has a big stake in the biodiesel biz traveled to Washington, DC to make the case for renewal of the federal $1-a-gallon biodiesel tax incentive.
The Iowa Biodiesel Board commended Governor Culver on the testimony. “Governor Culver clearly recognizes the important role biodiesel plays, both nationally and at home in Iowa,” said Randy Olson, Executive Director of IBB. “We applaud his leadership and hope for that same level of support in Iowa for state biodiesel legislation.” 
The USDA and the Department of the Navy (DoN) have agreed to work together to develop advanced biofuels and other renewable energy systems.
Outside of location, location, location (for real estate, at least), the three most important words in business might be timing, timing, timing. You get both when you attend the National Biodiesel Conference and Expo, Feb. 7-10 in the Dallas-Forth Worth area (actually Grapevine’s Gaylord Texan Resort & Convention Center).
An energy source made from biomass that’s touted as “magic coal from the steam cooker” will make its debut at the
It took nature millions of years – by means of simple chemical processings mankind is in the meantime capable to solve the issue within just a few hours: biowastes, crop residues and organic wastes result in highly efficient combustibles, at the same time offering a profitable benefit to the environment. Compared to brown or black coal, the “Green Coal” Gco(c) is completely CO2-neutral and will contribute to a considerable reduction of CO2 emissions.
