The funding is in response to a funding opportunity announcement from DoE in March. The chosen awards were selected as the best biofuels projects to stimulate the design and demonstration of a comprehensive system to handle the harvesting, collection, pre-processing, transport, and storage of sufficient volumes of sustainably produced biofuel feedstocks.

Feedstocks or combinations of feedstocks for biofuels that were considered include: agricultural residues, energy crops (e.g., switchgrass, miscanthus, energycane, sorghum, poplar, willow), forest resources (e.g., forest thinnings, wood chips, wood wastes, small diameter trees), and urban wood wastes.
