Hybridizing Power Plants with Batteries

|

General Electric’s steam, gas, and wind turbines make up a large portion of the world’s electricity generating capacity. The company announced last week that it will extend its battery storage solutions to all of its power plants worldwide. This combination of energy storage and gas turbines promises supportive flexibility for the  … Read More

New Technology Improves Switchgear Performance

New Technology Improves Switchgear Performance

|

It’s no secret to the manufacturers who provide switchgear that their products are in ever-greater demand today. That’s because switchgear plays such a critical role in the operation of uninterruptable power supply systems. And these days, there are more end-users than ever—data centers, hospitals,financial institutions, manufacturers—that can’t afford to lose  … Read More

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  … Read More

Variable Frequency Drives (VFDs) in Municipal Projects

|

What kind of difference can a variable frequency drive—better known as a VFD—make for a municipality? A significant one. Just look at the town of Mooresville in North Carolina, where a VFD developed by Eaton has not only boosted the energy efficiency of the municipal water treatment plant, but has  … Read More

The common denominator among those employing energy management approaches is rising energy costs, points out Damian Smith, president/chief engineer for Total Energy Concepts. “It’s a hot topic as far as financials go, because it’s a direct expense that affects the bottom line,” he says. “When your costs go up on  … Read More

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  … Read More

Pumps Operations in the Building Envelope

Pumps Operations in the Building Envelope

Water flows downhill. Nothing could be more simple. Getting water to the top floor of an urban skyscraper is a bit more difficult. Mere gravity flow or even accumulated static pressure head aren’t sufficient to accomplish this task. Pumps are obviously needed. But what kinds of pumps are used in  … Read More
