WSJ on Economic Problems of Biomass Plants

Jim Carlton points out in the Wall Street Journal some of the problems of biomass plants.
With all the plants and trees in the world, biomass energy would appear to have boundless potential.
Or as Georgia politicians are fond of saying, “Georgia is the Saudi Arabia of forest energy.”
Yet in the U.S., biomass power—generated mainly by burning wood and other plant debris—has run into roadblocks that have stymied its growth.

Here at the Northern Nevada Correctional Center, officials in 2007 built a $7.7 million biomass plant to meet all the power needs of the medium-security prison. But last month, two years after the plant opened, prison officials closed it, citing excessive costs.

“This was a project that was well intentioned, but not well implemented,” says Jeff Mohlenkamp, deputy director of support services for the Nevada Department of Corrections.

Even with a captive market (pun intended), biomass was not economically feasible.

Maybe it was an isolated case? Continue reading →

Video of Biomass Air Quality Hearing, Valdosta, 27 April 2010

A video of a hearing about the biomass plant Wiregrass Power LLC proposes to build in Lowndes County just outside of Valdosta was held in Valdosta on 27 April 2010 by the Air Protection Branch (APD) of the Environmental Protection Division (EPD) of the Georgia Department of Natural Resources (DNR).

Eric Cornwell of APD explains location, process flow, and specific items covered by the permit (soot, SO2, NOX, CO, VOC, HCL, etc., but not CO2). He remarks that Wiregrass Power LLC is building a small plant with a “lower emission limit in order to avoid some of the red tape” by getting a minor permit instead of a major permit. The first half hour concludes with Bob Turner, the plant manager, presenting similar material, ending with:

“No new carbon is added to the atmosphere when burning woody byproducts.”
I beg to differ on that: in the time it takes trees to grow back, there is indeed new carbon dioxide added to the atmosphere. More from Dr. William Sammons on that.

Back to the video of the hearing. Questions start at 00:29:44. Here are some time markers and very brief summaries of Q and A; see the video for the full questions and answers. Continue reading →
