Georgia-based Biomass Gas & Electric plans to grow 50 percent of the feedstock that will be required to power its soon-to-be-constructed biomass facility, Northwest Florida Renewable Energy Center in Port St. Joe, Fla., at its subsidiary AgTech Renewable Fuels LLC.
The company will begin work on the 45-megawatt power plant in the first quarter of 2010, and is currently working to raise capital to build a laboratory and nursery to grow arundo and miscanthus seed plantlets. AgTech Renewable was formed almost a year ago, upon licensing the technology rights from the University of South Carolina.
BG&E plans to use a micropropagation technology that is applicable for up to 50 species of perennial grasses. Although arundo and miscanthus can yield between 20 and 30 tons per acre, the major limitation in the widespread adoption of the two biomass crops has been the labor-intensive hand propagation and transplanting required for the sterile grasses. BG&E’s micropropagation technology involves growing thousands of plantlets in vitro that are then matured in bioreactors for mass row planting, drastically reducing labor requirements.
“We’re in the process of looking for growers, although it’s still a ways away,” said BG&E spokesman Keith McDermott. The laboratory and nursery will be in close proximity to where the farming operations will be, he added.
Besides energy grasses, NFREC will also utilize wood waste from the local forest industry. “What we’re trying to do is have a good mixture of open and closed-loop sources,” McDermott said. “We’re building the facility in the heart of the nation’s wood basket, so there are a tremendous amount of biomass opportunities. There are companies down there that have been in the timber business for many, many years, and because a lot of the paper industry has gone overseas, a big void has been left—not to mention the downturn in the economy with construction and building, so we’re definitely stepping into a place where we’re going to be able to affect the economy very positively.”
McDermott said BG&E doesn’t foresee using the farming operations for 100 percent of the required feedstock of NFREC. “Especially at the outset; we don’t want to put all our eggs in one basket,” he said. “We want to help support the local economy from the timber aspect, and also give the farmers something to plant, harvest and transport.”
