Powering Up with Centralized Biodigesters for Dairy Farms

Powering Up with Centralized Biodigesters for Dairy Farms

It is technically feasible to produce about 150 megawatts of generation (enough to power about 70,000 homes) from manure through the use of biodigesters, according to a study from the California Biomass Collaborative. The California Air Resources Board further estimates that the potential for methane capture from dairies amounts to about 3.1 million metric tons of carbon dioxide. Savings and Revenue Opportunities from Community Digester Systems Community digester systems not only provide useful power but also yield renewable energy certificates (RECs), carbon credits, and waste heat that can be used for multiple purposes. In some cases, the plants produce digested fiber that can be sold as bedding for cows, for composting, or for use by wholesale organic products companies. A summary of potential opportunities for cost savings and/or revenue generation is provided in Table...
