Some locally grown mustard seeds could soon be powering buses in Monterey County, California.
This story from the San Mateo County (CA) Times says the mustard seed oil could be turned into biodiesel by the end of this year:
By December, Monterey-Salinas Transit officials hope to have refined mustard-seed oil — which will be mixed with regular diesel fuel — from about 3,000 pounds of seeds harvested in August from a 10-acre field in the King City area.
“We’re going to be using our oil late this year,” said Hunter Harvath, assistant general manager of the transit agency.
The timing depends on when the seed can be pressed and refined. Presses are in short supply this time of year because the wine grape crush is under way, he said.
The mustard seed experiment began in February on 20 acres owned by San Bernabe Vineyards near King City. Pacific gold and wild California mustards were planted to determine which variety of the plant would produce the most seed oil.
The ton and a half of seed will produce about 750 to 800 gallons of biodiesel. Like other biodiesel, the mustard oil will constitute 20 percent of the fuel mixture that powers the buses, he said.
The article goes on to say the experiment with the wild mustard seed ran into a snag when the field was overrun by turnips.


An area in Central Florida already touted as a mecca for biodiesel production could be getting another biodiesel plant.

Schafer said the government could provide up to $25 million per company to refinance through a “guaranteed loan-type program for operating capital.” These types of loans are available through the Rural Development’s existing Business and Industry (B&I) Loan Guarantee Program. Under that program, the loan must be secured by a private lending agency – USDA does not make a direct loan.
Another nearly 1,400 megawatts (MW) of wind energy has been installed during the last three months, putting the U.S. wind energy industry on a record-setting pace again this year.

A new pilot plant that broke ground in Tennessee last week will be testing the use of switchgrass as a feedstock for cellulosic ethanol.
Earlier in the day, Governor Bredesen participated in the state’s first-ever Summit on Clean Energy Technology in Knoxville. “When it comes to facing the challenges of the future, Tennessee isn’t just talking the talk about clean energy technology, we’re walking the walk, rolling up our sleeves and getting to work,” said Bredesen. “The bottom line is that this plant and this partnership are going to do a lot of good for Tennessee’s future.”
