Design Optimization of an Ammonia-Based Distributed Sustainable Agricultural Energy System

Matthew Palys Anatoliy Kuznetsov Joel Tallaksen Michael Reese Prodromos Daoutidis

Small-scale, distributed production of ammonia better enables the use of renewable energy for its synthesis than the current paradigm of large-scale, centralized production. Pursuant to this idea, a small-scale Haber-Bosch process has been installed at the West Central Research and Outreach Center (WCROC) in Morris, MN [1] and there is ongoing work on an absorbent-enhanced process at the University of Minnesota [2], [3]. Using renewables to make ammonia would greatly improve the sustainability of fertilizer production, which currently accounts for 1% of total global energy consumption [4]. The promise of renewable-powered, distributed ammonia production for sustainability is in fact not…

Life-cycle greenhouse gas and energy balance of community-scale wind powered ammonia production

Joel Tallaksen Fredric Bauer Christian Hulteberg Michael Reese Serina Ahlgren

As well as being an innovative energy source, ammonia is a crucial component of most nitrogen fertilizers. Since the production of ammonia is very energy intensive and currently completely based on fossil energy, there is a considerable interest in developing renewably produced ammonia for use in agriculture and other sectors. This work presents a life cycle assessment (cradle-to-gate) of greenhouse gas (GHG) emissions and primary energy use for ammonia produced at community-scale using renewable wind generated electricity. Two different regions were studied: Minnesota (US) and Sweden. The results show that ammonia produced with wind-generated electricity has significantly lower fossil energy…

Ammonia Production Using Wind Energy: An Early Calculation of Life Cycle Carbon Emissions and Fossil Energy Consumption

Joel Tallaksen Michael Reese

Industry professionals and others have begun to consider the use of ammonia as a substitute for fossil energy in the fuel, fertilizer, and chemical sectors. Several factors are driving this concept; including, energy security concerns, the potential for economic development, and reducing the environmental consequences of fossil energy use. In terms of environmental concerns, it is important to determine the potential impacts of producing ammonia before a major switch to ammonia can be considered. This study examined fossil energy use and carbon emissions in the production of ammonia, using life cycle assessment (LCA) methods to analyze production at a novel…
