Cellulosic biofuels are made from the non-edible parts of plants, such as switchgrass, miscanthus, and corn stover. These crops can be grown on marginal land, which means land that is not suitable for growing food crops. This can help to reduce competition for food and water resources.
The Argonne study, published in the journal Environmental Research Letters, uses a systems analysis approach to identify the best locations for growing cellulosic biofuel crops. The analysis takes into account a variety of factors, including land availability, soil quality, climate, and transportation infrastructure.
The study finds that there are significant opportunities for growing cellulosic biofuel crops in the Midwest and Southeast regions of the United States. These regions have an abundance of marginal land, suitable soil and climate conditions, and well-developed transportation infrastructure.
Growing cellulosic biofuel crops in these regions could create jobs, stimulate economic growth, and reduce greenhouse gas emissions. The study estimates that planting just 1 million acres of cellulosic biofuel crops could create up to 1,500 jobs and $50 million in economic activity.
"Our study provides a roadmap for producers who are interested in growing cellulosic biofuel crops," said Daniel De La Torre Ugarte, an environmental scientist at Argonne and lead author of the study. "We have identified the best locations for growing these crops, and we have also shown how they can benefit the local economy and community."
The study is part of a broader effort by DOE to support the development of sustainable biofuels. Biofuels are an important part of the nation's clean energy portfolio, and they can help to reduce our dependence on foreign oil.
"This study is a valuable resource for producers who are interested in growing cellulosic biofuel crops," said Robert Wagner, acting director of DOE's Bioenergy Technologies Office. "We are committed to supporting the development of sustainable biofuels, and this study is a step in that direction."
