Researchers at the U.S. Department of Energy's Joint BioEnergy Institute (JBEI) have created a technoeconomic model that should help accelerate the development of a next generation of clean, green biofuels that can compete with gasoline in economics and well as performance. This on-line, wiki-based model enables researchers to pursue the most promising strategies for cost-efficient biorefinery operations by simulating such critical factors as production costs and energy balances under different processing scenarios.

In the JBEI technoeconomic model, each unit of operation in the biofuels process flow sheet has a dedicated discussion thread, making it possible for experts in different fields to collectively and publicly address issues associated with different sections of the biorefinery. To make the model interactive and dynamic, and to ensure its accuracy, parameters and assumptions will be updated in response to feedback obtained from users in the biofuels research community.
"The goal is to provide a tool that incorporates assumptions in a transparent manner, and allows comparative analyses to be made from the same starting point," says co-author Simmons, who heads JBEI's Deconstruction Division. "Our model is also designed to allow users to analyze the scenarios that are of most interest to them, and to gather meaningful information from experts across disciplines in a centralized model."
