Biogas from dairy farms in California: report looks at regulatory issues
Biogas is rapidly becoming one of Europe's most important biofuels, with the sector scaling up to produce the alternative to natural gas on an industrial scale. Last year, thousands of plants produced an estimated 5.3 million tonnes of oil equivalent energy from biogas (overview). The developments in the EU are such that experts are looking at ways to open the main natural gas grids to feed in biomethane. Some estimate that biogas can replace all of the EU's natural gas imports from Russia by 2020. On the continent, the gas is increasingly produced from dedicated energy crops and used as an efficient transport fuel in CNG vehicles (overview here and here).
In the U.S., the sector is in its infancy. But the outlook for biogas is very good (previous post), which is why analysts there are proactively researching regulatory issues. A new report released by the Energy Policy Initiatives Center (EPIC) at San Diego University examines these regulatory challenges as they relate to biogas production and use on California's Dairy Farms. California is home to about 1,800 dairies that represent over 1.7 million dairy cows (graph, click to enlarge), which produce a significant amount of biomass that can be converted to biogas by anaerobic digestion. California dairies have a methane production potential of about 40 million cubic feet per day (1.1 million cubic meters) or 14.6 billion cubic feet/year (413 billion cubic meters). But the state currently has only 22 biogas-producing digesters located on dairy farms.

Biogas is produced through a biological process called anaerobic digestion, in which bacteria convert organic materials into biogas in an oxygen-free environment.
Converting cow manure and other agricultural wastes to a clean and useful energy sources helps to reduce greenhouse gas emissions by capturing methane that would otherwise have been released into the atmosphere. It also creates a renewable gas that can replace traditional natural gas for electricity generation and, because other organic wastes can be mixed with manure, biogas production can help to divert organic materials away from our landfills.
EPIC is an academic and research center of the University of San Diego School of Law that studies how energy policy issues affect the San Diego County region and California. EPIC integrates research and analysis, law school study and public education, and provides legal and policy expertise and information about efficient and environmentally responsible solutions to our future energy needs.

Biogas production via anaerobic digestion has attracted significant attention as a viable greenhouse gas reduction strategy, largely because methane is a potent greenhouse gas with 21 times the global warming potential of carbon dioxide. But regulations related to biogas are still evolving as the industry grows, so it is important to identify current regulations that might create disincentives and to identify issues that need further attention to ensure that biogas can play a vital role in our greenhouse gas reduction strategy. - Scott Anders, EPIC’s director and author of the reportThe report titled Biogas on Dairy Farms: A Survey of Regulatory Challenges [*.pdf] provides background information on how biogas is produced and used; identifies challenges or issues of uncertainty related to air quality, water quality, solid waste management, electricity, and natural gas regulation; and recommends ways to encourage biogas production in California:
