Talking Interesting Bio news

Not sure if its repost here but i think not, but this is good news.

Cheaper Veggie Diesel May Change the Way We Drive

Brian Handwerk
for National Geographic News

November 15, 2005
Japanese scientists may have found a cheaper and more efficient way to produce "biodiesel." The renewable, vegetable oil-based fuel can be used in conventional diesel engines, which are found in about 2 percent of cars currently sold in the U.S. and in about 40 percent in Europe.

The breakthrough could be just in time—industry experts say that demand for the cleaner, greener fuel is on the rise.


Any vegetable oil can become fuel, but not until its fatty acids are converted to chemical compounds known as esters. Currently the acids used to convert the fatty acids are prohibitively expensive.

Michikazu Hara, of the Tokyo Institute of Technology in Yokohama, Japan, and his colleagues have used common, inexpensive sugars to form a recyclable solid acid that does the job on the cheap. Their research is reported in last week's issue of the journal Nature.

"We estimate the cost of the catalyst to be one-tenth to one-fiftieth that of conventional catalysts," Hara said.

The breakthrough could provide cost savings on a massive scale, he said, because the technique could fairly easily make the transition from the lab to the refinery—if interest warrants.

"We have developed this material for large-scale chemical production," Hara said. "Unfortunately, interest in biodiesel in Japan is not higher than in the U.S. and Europe."

Biodiesel Boom?

Though it has been historically limited, U.S. interest in the fuel appears to be rising rapidly.

"We are anticipating 75 million gallons [284 million liters] of production in 2005, and that's triple last year's production," said Jenna Higgins, a spokesperson for the National Biodiesel Board, a biodiesel-industry trade group.

Higgins cites several reasons for the surge, including government incentives and the rising cost and sometimes short supply of conventional diesel fuel.

A Minnesota law, which took effect September 29, mandates that virtually all diesel sold in the state has to be at least 2 percent biodiesel—provided local producers can match the demand.

"That created demand for about 16 million gallons [61 million liters] a year," Higgins said. A larger boost was provided by a U.S. federal tax credit that encourages blending biodiesel and regular diesel fuels.

"That has made biodiesel more cost competitive and significantly increased demand," she said.


The most common biodiesel fuel product, B20, is 20 percent biodiesel and 80 percent conventional diesel. Most commercially available biodiesel is sold in such blends.

Generally, biodiesel costs more at the pump than regular diesel fuel. The cost difference is about the same as it is between premium and regular gasoline.

Biodiesel production costs are tied to weather patterns that affect crops used in its production, such as soybeans or rapeseed (canola). Diesel costs are tied mainly to the cost of its source, petroleum.

Currently the U.S. is home to some 45 biodiesel plants. The average plant produces just 6.5 million gallons (24.6 million liters) a year, but larger facilities may soon be coming online.

Tip of a Green Iceberg?

Monty Goodell is president and CEO of Houston, Texas-based Cogeneration Technologies, parent company of the Biofuel Industries company. He is developing a 50-million-gallon (189-million-liter) facility. The operation would double the entire U.S. biodiesel output, based on 2004 numbers.

"We are at the tip of the iceberg for biodiesel," he said.

"There were 500,000 gallons [1.9 million liters] of biodiesel produced five years ago [in the United States]," Goodell said. "Last year there were 25 million gallons [95 million liters] of B100 biodiesel produced—a 5,000 percent increase in just five years." B100 is 100 percent biodiesel—no diesel added.

If B20 ever becomes a diesel fuel standard, Goodell says, biodiesel demand could be staggering.

"[There were] 55 billion gallons [208 billion liters] of petroleum diesel consumed in the U.S. last year," he said. "[A biodiesel requirement of] 20 percent would equal a requirement of 11 billion gallons [42 billion liters] of B100 biodiesel needed" for mixing with diesel fuel.

The word does appear to be getting out.

"We are seeing quite a bit of demand," said John Rymes, of Rymes Heating Oils in Concord, New Hampshire. Rymes has several biodiesel pumps and also provides biodiesel for construction-vehicle operators and home heating-oil consumers.

"I'm not going to tell you that we've generated a lot of income from it, but we're committed as a company to try to bring a cleaner-burning fuel to the region," he said.

The U.S. Environmental Protection Agency has determined that the greener fuel emits only a third of the unburned hydrocarbons and half of the carbon monoxide and particulates that standard diesel fuel emits. Furthermore, biodiesel's sulfur oxide and sulfate emissions, which cause acid rain, are negligible.

The fuel is also biodegradable, so safety concerns and pollution issues are minimal.

Rymes explains that New Hampshire fuel taxes currently take a big bite out of his potential profits on the fuel. But, to stimulate interest, he keeps biodiesel priced as competitively as he can.

"It's a great product," he said, "and there are a lot of people interested in using it."

I hope the increased production will bring the price and availability down. Although I'm pretty sure it won't. I currently pay $0.11 per gallon more for B2...and drive 20 miles out of the way for the privledge. Hardly seems worth the effort.

Wow they are putting it to you.... on the farm for B5 it adds $ .02 per gal.
I would see if you can get B100 and blend yourself or if you can in your locality get a 300 gal tank and have the fuel bulk dropped. Look for fuel suppliers at www.biodiesel.org and see if anyone else in your area can supply you.
