Combined heat and power (CHP) is used to describe the process of obtaining electricity and useful heat from a common fuel source. In years past, this process was called cogeneration, a term most engineers are familiar with. Whether it is called CHP, cogeneration, or trigeneration (heating, cooling, and electric production), the concept offers remarkable promise for energy efficiency in a world that wants to lower costs, reduce dependence on fossil fuels, and cut greenhouse gas emissions.

Energy Management Systems

To exemplify the evolving nature of energy management systems, Greg Turner, vice president for Honeywell Business Solutions, recalls a recent conversation in which a hospital facilities manager spoke of how he’d have to come up with budget figures once a year that would either be accepted or rejected.

“Now I get calls almost

Integrating CHP with Microgrids

Integrating CHP with Microgrids

While combined heat & power (CHP) may not be appropriate for integration into all microgrids, it definitely does have its place in a lot of them.

CHP systems output heat (or cooling), as well as electricity, primarily as a topping cycle. “The prime mover is typically a reci­procating engine or a turbine,”

Editor’s Comments: Seeing the Invisible

It was one of those clear days in which early rain had bathed every atom and left the world looking more three-dimensional than usual. I paused during a hike and stood overlooking the velvet folds of California’s coastal mountain range. Raptors rode upwellings in the distance. One of them—a hawk—landed on a

Cogen Case Study: Ronald McDonald House, New York City

Cogen Case Study: Ronald McDonald House, New York City

What began in 1974 as a Shamrock Shake-driven fundraiser to help families with sick children is today a network of 322 Ronald McDonald Houses in 57 countries. The first Ronald McDonald House (RMH), in Philadelphia, PA, was meant to serve as a “home away from home” for families spending time

NY’s Storage Industry’s Annual Global Revenues Grew 50%, to $906 Million Between 2012 and 2015, Projected Increase to $8.7 Billion by 2030

NY’s Storage Industry’s Annual Global Revenues Grew 50%, to $906 Million Between 2012 and 2015, Projected Increase to $8.7 Billion by 2030

The New York State Energy Research and Development Authority (NYSERDA) announced today that jobs in the State’s energy storage sector grew to approximately 3,900 – a 30 percent increase from 2012 through 2015, according to a recently completed report. New York’s commitment to clean energy, including its nation-leading energy goals,

The Costs and Benefits of Anaerobic Digesters

The Costs and Benefits of Anaerobic Digesters

Anaerobic digesters are a mature, proven technology. They take sludge, manure, and other organic waste materials and produce methane (natural gas) fuel. Nobody questions their technological capabilities. However, the question remains as to their economic benefits. In terms of dollars and cents, how much economic sense do anaerobic digesters make?
