Tag: combined heat and power

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.

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

A New Team of Horses

A New Team of Horses

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

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

San Luis Obispo County, located along the Pacific Ocean in Central California, midway between San Francisco and Los Angeles, is known for its breathtaking seascapes, miles of oak-studded rolling chaparral hills, and prolific wine production—the third largest wine producing county in California. Its population of 283,000 is located amongst small

Benefits of Community Microgrids

Benefits of Community Microgrids

However they are defined, everyone agrees community microgrids provide benefits. Centralized utility systems and aboveground distribution lines expose customers to regional and local outages, “and while they are highly reliable, centralized utility grids can’t ensure local resilience,” notes Peter Douglass, project manager for the Microgrid Institute, a collaborative organization supporting global development of microgrids and distributed energy

The Future of Fuel Cells

The Future of Fuel Cells

In motor racing, a fuel cell consists of a container that protects a bladder and baffle so that, in the event of a crash, the fuel is contained, keeping the driver safe from fire. In the broader context, fuel cells are devices that convert stored chemical energy into electrical energy,

Biogas and Cogeneration

Biogas and Cogeneration

Biogas has been quietly serving as a fuel for combined heat and power (a.k.a. cogeneration) plants and as a revenue generator for waste treatment facilities, landfills, and dairies for some time, mainly in Europe. But it is becoming more popular here in the US as municipalities and utilities seek out
