One key factor in developing a sustainable biofuels policy is to realistically estimate the amount of biomass that can on average be grown on a given amount of land to produce cellulosic biofuel. But Will energy crop yields meet expectations? found that the highest predicted yields, and associated expectations of how much biomass could be grown for energy, could not be supported by an overview of studies in this field.

“From a bioenergy standpoint, that’s when we’re going to have to figure out how we prioritize growing crops for bioenergy,” said Endres, who also is an affiliate of the Energy Biosciences Institute, a collaboration involving the U. of I., the University of California at Berkeley, the Lawrence Berkeley National Laboratory and BP, an energy company.

Kior declined 41 percent to 63 cents at 10:23 a.m. in New York, the most intraday since its June 2011 initial public offering at $15.

The company needs additional capital by April 1 and its only potential source of near-term financing is a March 16 commitment letter from billionaire investor Khosla, according to a filing with the Securities and Exchange Commission yesterday.

The 100-megawatt (MW) plant was scheduled to be built at the Port of Blyth, creating 300 construction jobs and 50 operational jobs, RES said.

The company received permission to build the project from the government last year.

"It's bitterly disappointing for RES that we are unable to bring this exciting project forward, and deliver the significant boost it would have represented for the Blyth and Northumberland economy," RES Chief Operating Officer Gordon MacDougall said in a statement.

"However, the gradual erosion of support for dedicated biomass leaves us with no other option," he added.
