Energy Newsbriefs Blog

This current awareness service is prepared by the WSU Energy Program Library with funding from the U.S. Department of Energy State Energy Program. This information is provided for energy professionals and interested members of the public to highlight recent energy-related news, articles, and reports that discuss energy efficiency, energy conservation, and renewable sources of energy in engineering and policy circles.

Energy, Exergy or Economy? Figuring the Benefits of CHP

Cogeneration & On-Site Power Production, Jul/Aug 2014, by Jacob Klimstra.
http://www.cospp.com/articles/print/volume-15/issue-4/features/energy-exergy-or-economy-figuring-the-benefits-of-chp.html

"For many readers familiar with the concept of energy balances and tools such as Sankey diagrams, background knowledge of thermodynamics is often lacking. That might not be an issue for a practical user, but such knowledge can be of utmost importance when designing installations and when promoting the benefits of cogeneration for policymakers. In a series of articles, Jacob Klimstra discusses the energy balance of cogeneration installations."

"Using laws of thermodynamic analysis to evaluate the energy and power characteristics of wastewater and beneficial uses of biogas offers greater insight into best business practices and what is achievable."

Combined Heat and Power and Clean Distributed Energy Policies

American Council for and Energy-Efficient Economy (ACEEE), July 2, 2014, by Anna Chittum and Neal Elliott. (Free registration required to view full-text of report.)
http://www.aceee.org/policy-brief/combined-heat-and-power-and-clean-distributed-energy-poli

"Combined heat and power (CHP) systems generate electricity and useful thermal energy in a single, integrated system. CHP is not a technology, but a particular way to deploy existing technologies. Heat that is normally wasted in conventional power generation is recovered as useful energy, so CHP systems are more efficient and provide environmental, economic, and energy system infrastructure benefits. However, several barriers impede cost-effective CHP applications, including lack of common interconnection protocols, discriminatory standby rates, and emissions regulations that do not recognize the improved efficiency levels of CHP systems."

Water Utilities Are Starting to Take Their Own Conservation Advice

Governing, Aug. 2014, by Elizabeth Daigneau.

"Wastewater treatment plants are often the biggest consumers of electricity in their area. Gresham, Ore., and Washington, D.C., are making moves to change that."

More than Heat and Power: Cogeneration with New Gas Engine Technology

Cogeneration & On-Site Power Production, May/June 2014, by Michael Devine.
http://www.cospp.com/articles/print/volume-15/issue-3/features/more-than-heat-and-power.html

"Cogeneration today goes well beyond simultaneously generating electricity and hot water or steam. Today's usable engine outputs can also include heated air, chilled water produced by absorption chillers, and carbon dioxide from purified exhaust. In other words, a single engine-generator can produce two, three or four useful outputs at once. With today's generating technologies, electrical efficiencies up to 45% and total resource efficiencies upwards of 90% are achievable. And cogeneration systems do not necessarily need to operate full-time at full load to be cost-effective–low-cost and low-intensity configurations can bring attractive returns in many settings."

High Solids Anaerobic Digestion + Composting in San Jose

BioCycle, Mar./Apr. 2014, by Nora Goldstein.
http://www.biocycle.net/2014/03/28/high-solids-anaerobic-digestion-composting-in-san-jose/

"A facility that marries dry anaerobic digestion and composting under the same roof to process the organic fraction of municipal solid waste opened for business late last year at the south end of the San Francisco Bay in San Jose, California. Zero Waste Energy Development Company (ZWEDC) — developer and owner of the 90,000 tons/year facility — recognized the benefits of colocation to enable extraction of the energy value of the food waste, followed by composting of the digestate. The plant, comprised of 16 high-solids dry fermentation digesters and four in-vessel composting tunnels, began receiving organics from the commercial sector in San Jose in mid-December."
