Many Industries Use Combined Heat and Power to Improve Energy Efficiency

Energy Collective, Jul 28, 2016.
http://www.theenergycollective.com/todayinenergy/2383773/many-industries-use-combined-heat-and-power-to-improve-energy-efficiency-2

"Combined heat and power (CHP) systems have long been used to reduce the overall energy intensity of industrial systems. There are two types of combined heat and power, depending on whether the system produces power first, then heat, or heat first, then power. In topping cycles, the hot exhaust of an electricity generator such as a natural gas turbine or reciprocating engine is used to provide process heat, hot water, or space heating for the site. According to preliminary 2015 data, topping cycles are used by 89% of total CHP capacity. In bottoming cycles, also referred to as waste heat to power, wasted heat from a furnace or other high-temperature industrial processes is recovered and used for power production."

Applying Combined Heat and Power Systems

Consulting-Specifying Engineer, June 2016, by Rodney V. Oathout.
http://www.csemag.com/single-article/applying-combined-heat-and-power-systems/6209f622802ca8a577b34246b4fc074a.html

"Cogeneration systems, often referred to as combined heat and power (CHP) systems, generate both electricity and thermal energy. As they become more common in the United States, engineers must understand the nuances and design strategies for successful application."

How CHP Gets Going

On-Site Energy Management, Mar/Apr. 2016, by Tom Bryan.
http://www.onsiteenergymanager.com/articles/4823/how-chp-gets-going

"In regional markets with high spark spreads, assessing the viability of combined heat and power projects begins with a few simple questions about hot water. If the conditions are right, cogen is a good investment with multiple pathways to completion."

Combined Heat and Power (CHP) Technical Potential in the United States

U.S. Department of Energy, Advanced Manufacturing Office, Mar. 2016.
http://energy.gov/eere/amo/downloads/new-release-us-doe-analysis-combined-heat-and-power-chp-technical-potential

"This study provides data on the technical potential in industrial facilities and commercial buildings for “topping cycle” CHP, waste heat to power CHP (WHP CHP), and district energy CHP in the U.S. The report provides valuable data on the technical potential for CHP in strategic energy planning and energy efficiency program design. The study shows that within the U.S. there is estimated to be more than 240GW of technical potential at over 291,000 sites. Data is provided nationally by CHP system size range, facility type, and state."

CHP Update: Policies, Partnerships, and Challenges

Power Magazine, Feb. 2016, by Thomas W. Overton.
http://www.powermag.com/chp-update-policies-partnerships-challenges/

"Though combined heat and power (CHP) is getting increasing attention as a means of efficiency and reducing carbon emissions, the sector’s traditional challenges remain. But some generators and policymakers are working hard to deploy CHP in new and more economic ways."

Understanding Cogeneration Systems

Pure Power (supplement to Consulting-Specifying Engineer), Summer 2015, by Jerry Schuett and David Cummingham.
http://www.csemag.com/single-article/understanding-cogeneration-systems/ebec65943f512c49199b852db0b51104.html

"Cogeneration systems—also known as combined heat and power (CHP) systems—generate both electricity and usable thermal energy. These systems typically are used on campuses that have high heat load requirements." Describes three CHP system prime movers: back-pressure steam turbine, combustion turbine, and reciprocating engine.

Distributed Power’s Rising Importance for U.S. Electrical Infrastructure

Power Magazine, May 2015, by Devon Manz and others.
http://www.powermag.com/distributed-powers-rising-importance-for-u-s-electrical-infrastructure/?printmode=1

"Renewable generation may be the most talked-about form of distributed power these days. However, historically, engine- and turbine-based smaller-scale generation—strategically located where needed by loads or for grid support—has supplied valuable distributed power. For many reasons, the roles for distributed power provided by rotating and reciprocating equipment continue to increase."
