Martens publishes in Energies
Associate Professor Bobby Martens published in the journal Energies,. Martens co-authored the article "Cost Assessment of Centralizing Swine Manure and Corn Stover Co-Digestion Systems" with Gabrielle M. Meyers, Daniel S. Andersen, and D. Raj Raman, all of Iowa State University.
The article explores the economics of anaerobic digestion systems in Iowa to evaluate reasons for low deployment and explores the production cost impacts of biogas cleaning and injection into the natural gas grid, amending manure with biomass, and centralizing digesters across multiple farms. Key findings include that under the model assumptions, distributed, farm-scale digesters are not competitive with average natural gas prices in Iowa.
