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.

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."

Micro-CHP: A Tool for Increased Market Access

Cogeneration & On-Site Power Production, May/June 2014, by Jan de Wit, Mads Moeller Melchiors and Laila Grahl Madsen.

"...present perspectives for increased CHP market penetration, as well as reduced primary fuel consumption and carbon savings based on one year's field testing of fuel cell-based micro-CHP units."

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."

Fuel Cell CHP Passes the Point of No Return

http://www.cospp.com/articles/print/volume-15/issue-2/features/fuel-cell-chp-passes-the-point-of-no-return.html

"The use of fuel cell technology in combined heat and power applications is commonly viewed as being at an early stage of development. However, Arjen de Jong and Martin Horstink argue that significant advances in the last 12 months mean this is no longer the case." 

Optimized Solutions for Industrial Cogen Units

Cogeneration & On-Site Power Production, Jan.-Feb. 2014.
http://www.cospp.com/articles/print/volume-15/issue-1/features/optimized-solutions-for-industrial-cogen-units.html

"CHP [Combined Heat & Power] installations are often associated with industrial process and so any failure at the plant can be a commercial disaster for the owners if they have to cease production as a result. However, with a more sophisticated set up it is possible to continue to operate seamlessly, even in the event of an unexpected gas turbine trip, explains Stef Verhagen of NEM Energy bv."


Making Power Multitask With CHP/CCHP

Multitask_With_CHPCCHP_24940.aspx


"Cogeneration and trigeneration: industry experts say the time is ripe—again—for the increased use of these technologies. Cogeneration, or combined heat and power (CHP), uses a heat engine or power station to generate electricity and heat for onsite uses. Trigeneration, or combined cooling, heat, and power (CCHP), is the simultaneous generation of electricity and useful heating and cooling as a result of the combustion of fuel or the action of a solar heat collector."

Standby Rates for Combined Heat and Power Systems: Economic Analysis and Recommendations for Five States

Prepared by Brubaker & Associates, Inc. and the Regulatory Assistance Project for Oak Ridge National Laboratory, ORNL/TM-2013/583, Feb. 2014.
http://raponline.org/document/download/id/7020

"Standby, or partial requirements, service is the set of retail electric products for customers who operate onsite, non-emergency generation. These rates represent the cost of services utilities provide when customer generation is not operating or is insufficient to meet full load. Trends show that distributed generation is not rare anymore and that old ideas about risk have been replaced by utility operator confidence in anticipated performance. This paper presents the results of an analytical assessment of the rates, terms, and conditions for standby service in five states: Arkansas, Colorado, New Jersey, Ohio, and Utah."

2013 Peer Review Report [DOE Bioenergy Technologies Office]

U.S. Department of Energy, Bioenergy Technologies Office, Feb. 2014.
http://www1.eere.energy.gov/bioenergy/pdfs/2013_peer_review.pdf


Reports on the results of a comprehensive external review of the DOE Bioenergy Technologies Office's research, development, demonstration, and deployment portfolio. The review was "designed to provide an external assessment of the projects in BETO's portfolio and collect external stakeholder recommendations on the overall scope, focus, and strategic direction of the Office. Results from the peer review process are used to inform programmatic decision making; to enhance active project management; and to modify, expand, or discontinue existing projects."

The key technology areas reviewed were: 1) Algae; 2) Analysis and Sustainability; 3) Biochemical Conversion; 4) Biodiesel; 5) Bio-Oil; 6) Feedstock Production and Logistics; 7) Gasification; 8) Heat and Power; and 9) Integrated Biorefineries.

Planning for District Energy, CHP and Microgrids: A Checklist for Campus Administrators

District Energy, First Quarter 2014.
http://www.districtenergy-digital.org/districtenergy/2014Q1?pg=38#pg38

"Owners and operators of multibuilding campuses face significant pressure to reduce operating and capital costs, maintain reliable services and become better stewards of the environment. To meet these challenges, an increasing number of campuses are turning to district energy, combined heat and power and/or microgrids. Effective planning ... will enhance the likelihood that savings associated with the power usage and climate control needs of individual buildings will be realized and that the central plant and distribution system can be ideally located."
