Metabolix to get $6M From DOE for Denser Switchgrass

Metabolix is one of 8 firms and research organizations named in a Department of Energy grant program that will put $47 million to work making biomass more productive for fuels and chemicals. All in an effort, of course, to unhitch our economy from fossil fuels.

Metabolix already has a way to make bio-based plastics (polyhydroxyalkanoate, or PHA resins) from sugars, and has been doing it at commercial scale with agro partner Archer Daniels Midland. But it has also been spending a great deal of its resources upstream on the biomass end, and can grow switchgrass with PHA inside it.

 The DOE award will give the firm $6 million (actually, it’s $6,000,001. not sure what the extra buck is for) to, in their words “use high temperature conversion to produce denser biomass and other products that can be further processed to make fuels such as butanol, chemicals such as propylene and other materials to improve the economic competitiveness of future biorefineries.”

I will admit to not fully grasping the meaning of “to produce denser biomass” yet, but I’ll be looking out for more details. Still, this announcement hit 7 of my cleantech topic categories (see above!) so it’s well worth mentioning now.

Metabolix was one of the earlier cleantech firms to IPO (helpful to do so before  worldwide recession, is the lesson here). Laurence Alexander of Jeffries & Co. is a fan of the stock, rating the firm a “buy.” He had this to say in a note to clients about the DOE/Metabolix grant: “ We view the announcement as incrementally positive. It should help Metabolix strengthen its technology platform while reducing concerns that the early-stage research into the switchgrass PHA platform could represent a cash drain that detracts from the more timely PHA plastic and PHA-based chemicals platforms.”  Sounds like Metabolix will be able to walk and chew gum at the same time, thanks to this announcement.

On a related note, the news value around the word “switchgrass” has been rather low of late. In this Google Trends chart, you can see little activity in last few years.

A great deal of attention in the biofuels segment has focused on cellulosic waste materials (wood chips, corn cobs etc) or gassification of biomass. Switchgrass was hot when the nation was going to grow dedicated crops for bio-based energy. We’ll have to see if a new research push will bring it back into the public eye.
