Abstract
Current market potential for biogas-to-energy projects in the United States is analyzed based on levelized cost of energy (LCOE) estimates for producing renewable electricity, compressed natural gas (bio-CNG) and renewable natural gas at 2,837 landfills, wastewater treatment plants and swine farms in North Carolina having biogas resource potentials of 13 m3/d to > 380,000 m3/d. The LCOE estimates are generated using new approaches for modeling biogas collection from multiple sources via physical pipeline networks or tanker truck transport (a.k.a. “virtual” pipelines) in combination with recent production and cost functions published elsewhere. Whereas the LCOE estimates end up being significantly higher than 2022–23 prices for electricity and natural gas in regional U.S. energy markets, bio-CNG projects collecting > 100 MMBtu/d (1 MMBtu ∼ 1 GJ) of biomethane yield LCOEs on par with recent prices for CNG for transportation of $26–$51/MMBtu. When incentives available through federal and certain state government programs are considered, sites in pipeline networks or in virtual pipelines with biomethane collection rates as low as 45 MMBtu/d could become economically viable. The results of this study help quantify the potential for monetizing an underutilized energy resource in the U.S. that can contribute to decarbonizing the nation's energy production.

Lincoln Pratson is a professor in the Nicholas School of the Environment's Division of Earth & Ocean Sciences. He has been Chair of EOS, Director of the Duke University Energy Hub, Associate Director of the Gendell Center for Engineering, Energy & the Environment at Duke, served on the Executive Committee for the Research Triangle Energy Consortium (https://www.rtec-rtp.org/), and was a co-founder & co-director of the Sustainable Energy Fellowship (http://www.teachenergy.org/). Pratson is a geologist/geophysicist by training. He has consulted for major oil companies and helped co-found an energy service company that provides state-of-the-art gravity data used to explore for offshore oil and gas reserves. Pratson co-leads a research group at Duke on energy systems. The research has been supported by the DOE, DoD and private industry. Working with students, Pratson is conducting research into carbon capture and storage, integrating different forms of energy storage and renewable energy generation into the electricity industry operations, assessing current and future water use in thermo-electric power generation, and evaluating future demand for and supplies of energy resources.
