Tag: distributed energy

Distributed energy, also district or decentralized energy is generated or stored by a variety of small, grid-connected devices referred to as distributed energy resources (DER) or distributed energy resource systems. Conventional power stations, such as coal-fired, gas and nuclear powered plants, as well as hydroelectric dams and large-scale solar power stations, are centralized and often require electricity to be transmitted over long distances. By contrast, DER systems are decentralized, modular and more flexible technologies, that are located close to the load they serve, albeit having capacities of only 10 megawatts (MW) or less.

A Growing Trend

A Growing Trend

Cogeneration systems, also known as combined heat and power, have traditionally been installed by larger industrial users with high steam and power demands and by smaller, institutional users such as universities and hospitals. Since the early 2000s, smaller industrial and commercial companies have discovered cogeneration utilizing natural gas-fired reciprocating engines,

The Strongest Link in the Chain

The Strongest Link in the Chain

Renewable energy—and solar energy in par­ticular—has a problem. Because it is subject to the vagaries of sunshine and wind for power generation, it is often not available when it is needed most. For those nighttime hours when the sun is not available and cloudy days when sunlight is minimal, provisions

Editor’s Comments: Cross-Pollination and Collaboration

Iwatched honeybees land on the plum tree in my yard recently. With a hum of wingbeats, each insect touched down on a delicate blossom, withdrew its sweetness, and headed off to the next, the marigold pouches on its hind legs swollen with pollen.

What struck me was the invisible network of

Lithium-ion Batteries: How Safe Are They?

Lithium-ion Batteries: How Safe Are They?

Lithium-ion batteries are energy dense, able to store an ever-increasing amount of electrons in a relatively small space. As the number of devices that they supply power to grows exponentially, it becomes more and more important to understand their chemistries, constructions, and potential limitations. We recently reached out to Brian

Younicos to Deliver Largest Y.Cube Deployment in US to Austin Energy

Younicos has signed an agreement to deliver a megawatt-scale battery storage system to Austin Energy, as part of a U.S. Department of Energy (DOE)-funded initiative known as the Sustainable and Holistic Integration of Energy Storage and Solar PV (SHINES) project.

Younicos will collaborate with the project’s prime contractor, Doosan GridTech, to

A Technology’s Transformation

A Technology’s Transformation

Fuel cell technology is elegant in its simplicity. An anode, a cathode, and an electrolyte allow positively charged hydrogen ions to move between the two sides of the cell, converting chemical energy into electricity. And the only bi-product is water.

Why, then, has this form of energy storage not been widely

Community Microgrids

Community Microgrids

Now, with the increasing availability and cost effectiveness of distributed energy resources (DERs), more and more customers—industrial, commercial, governmental, and residential alike—are taking power generation, and even storage, into their own hands.

Fuel Cells and Energy Sustainability

Fuel Cells and Energy Sustainability

Given that energy sustainability and energy economics are top-of-mind among business leaders, politicians, and the public these days, hydrogen fuel cells may be viewed as a savior technology. If that statement seems hyperbolic, there is plenty of statistical evidence to support the growth of fuel cell use for both stationary
