Iowa State researchers are also looking to expand the anaerobic digestion feedstock mix to add flexibility and environmental benefits, reduce costs, simplify operations and so that more farmers could take advantage of the technology to make money and improve the environment.

The researchers see abundant possibilities for RNG in Iowa and beyond to address greenhouse gas emissions and to diversify farm income and reduce pollution in the state's waterways.
The development of biofuels is a major recommendation in Iowa's 2016 energy plan and the state economic development authority's 2018 Biomass Conversion Action Plan which has been funding research into various anaerobic digestion techniques.
According to a 2013 National Renewable Energy Laboratory (NREL) inventory, Iowa produces more manure than any other state but the sources are not sufficiently concentrated to make digestion feasible or economically profitable.
Researchers hope to enhance the efficiency, reduce the costs and create ancillary income streams that will persuade farmers in Iowa and beyond to add AD to their operations. To that end, the researchers will explore the use of mixed prairie grasses and winter cover crops, such as annual rye, for AD.
The project is funded with a $10 million grant from the USDA. (Source: Iowa State University, PR, Aug., 2020) Contact: Iowa State University, Prof. Lisa Schulte Moore, Natural Resource Ecology and Management, (515) 294-7339, , www.iastate.edu

"The ethanol industry's problem is bigger than the waivers. Even with DDG (livestock feed) sales, they (ethanol producers) are losing money because we have been awash in oil and now the recession has lowered prices." -- David Swenson, Iowa State University Economist speaking to the Iowa Farmers Union via Zoom on July 30.
In Iowa, at least 10 of the 43 plants had completely shut down at some point during the COVID-19 pandemic and others had limited production. Contact: David Swenson, Iowa State University, (515) 294-7458, firstname.lastname@example.org, www.iastate.edu

C-CHANGE researchers are developing new ways for farmers to produce RNG that could be used as an energy source both on and off farms. The project focuses on anaerobic digestion (AD) and new separation technologies, allowing biogas to be upgraded to RNG and distributed through the gas pipeline network.
The project director on the transdisciplinary and multi-institutional grant is Lisa Schulte Moore, a professor of natural resource ecology and management and associate director of the Bioeconomy Institute at Iowa State. According to Schulte Moore, the consortium will develop methods for farmers to make more efficient use of resources.

According to DOE, the projects will develop technology solutions to environmental siting and operational challenges to reduce project permitting time and costs, increase the certainty of project development outcomes and provide more deployment options at reduced costs. Three projects by the Electric Power Research Institute (EPRI), American Wind Wildlife Institute of Washington and Stantec Consulting Services of Topsham will receive $2.3 million to further the advancement of smart curtailment strategies to minimize energy loss from curtailment and wind farm environmental impacts to bats. $1.4 million will be awarded to National Renewable Energy Laboratory (NREL) of Golden, General Electric Renewable Energy of Greenville and the Iowa State University of Ame for projects dedicated to advancing the commercial readiness of bat deterrent technologies to minimize the need for curtailment.
The remaining $2.5 million will be allocated to SMRU Consulting of Friday Harbor, Oregon State University of Corvallis and Western EcoSystems Technology of Cheyenne to develop and validate pre- and post-construction monitoring and mitigation solutions for the offshore wind environment to ease regulatory barriers to deployment.
