Cogeneration or combined heat and power (CHP) is the use of a heat engine or power station to generate electricity and useful heat at the same time. Trigeneration or combined cooling, heat and power (CCHP) refers to the simultaneous generation of electricity and useful heating and cooling from the combustion of a fuel or a solar heat collector.

Shared Energy Resources

Shared Energy Resources

There is a familiar backstory in electric power generation that has influenced the industry over the 40 years since the Public Utilities Regulatory Policies Act of 1978 (PURPA) was signed into law. Industry veterans know this story and the younger generation is coming to learn it. Yet the story is

Mitigating Electricity Demand

Mitigating Electricity Demand

The slowdown in the growth of electricity consumption and the rapid growth of distributed energy resources currently underway in the electric power sector is causing important utility revenue losses, resulting in challenges to century-old utility business models and current regulatory policies. It’s also providing new opportunities for electricity customers.

CHP: Institutional Applications

CHP: Institutional Applications

Institutional facilities throughout the US are employing combined heat and power (CHP) to attain goals in energy efficiency as well as cost savings, resiliency, and greenhouse gas reductions.

Heat Farm

Heat Farm

The use of anaerobic digestion (AD) has grown rapidly in the agricultural sector over recent years and there are somewhere between 260 and 550 biogas plants on US farms. (The AgSTAR database lists 265 on-farm digesters as of November 2017. However, according to a USDA ERS report, “As of 2012,

District Heating and Cooling Systems

District Heating and Cooling Systems

Originating in the 19th century, district heating and cooling (DHC) systems today are taking advantage of new technologies to provide the energy efficiency and thermal flexibility needed in 21st century applications.

CHP and Microgrids—A Profitable Pair

CHP and Microgrids—A Profitable Pair

Often, two technologies emerge more or less simultaneously, and then reinforce each other as mutually compatible technologies. In doing so, they can create a kind of synergy together and make one another more efficient, more cost-effective, more profitable, and more useful—like a pair of horses working together to pull a

Energy’s Evolution

Energy’s Evolution

What does the future hold for microgrids? According to Peter Asmus, Research Director for microgrids at Navigant Research, as inertia carries the market forward in the coming decade, microgrids will present opportunities for new business models and technologies as well as an energy landscape transformed by distributed generation sources.

The New Era of Absorption Chillers

The New Era of Absorption Chillers

Although absorption chillers were introduced over a century ago, it is worth examining what’s new today and what’s next, while dispelling some old misconceptions. That’s because in recent years, absorption chiller technology has evolved dramatically. Absorption chillers are being used around the globe as an efficient solution wherever waste heat

Editor’s Comments: Complementary Technologies

Technological synergies make equipment working in harmony more efficient, cost-effective, and profitable.

Today, as the world moves toward increasingly decentralized power systems, an ever-growing number of architectures are combining solar, wind, geothermal energy, CHP, gas-fired generation, and energy storage. These hybridized systems are utilizing the attributes of each power source to
