Dung

Pacific Gas and Electric Co. (PG&E) last Thursday issued a request for information (RFI) to identify partners for a demonstration project reviewing technologies to produce biomethane. The cow dung-to-usable gas process can produce pipeline-quality natural gas, according to PG&E. Earlier in the month the Silicon Valley suburb of Palo Alto, CA, issued a request for proposals (RFP) seeking marketing and administrative help to expand its green energy programs to “green gas” and renewable energy credit (REC) segments.
