Con Ed Looks to Batteries, Microgrids, and Efficiency to Delay $1B Substation Build

July 26, 2014 by Katherine Tweed

Consolidated Edison is taking a new approach to delivering reliable power that is as radical as the gentrification sweeping New York’s outer boroughs. Con Ed filed a proposal for a Brooklyn/Queens Demand Management Program, or BQDM, that it hopes can defer the cost of building a $1 billion substation.[read more]

Heres a Way to Get Utilities to Embrace Solar and Batteries: Let Them Own the Inverter

July 8, 2014 by Stephen Lacey

Utilities own a wide range of devices on the transmission and distribution grid to manage power quality. But there's a power control device that may be much more familiar to the hundreds of thousands of American homeowners with solar on their roofs: inverters. Should utilities own those too?[read more]

Batteries and the Future

Before the massive electrical grids and power lines that our current infrastructure relies so heavily upon, batteries were how we made electricity. As batteries advanced, so did our technology. From lead-acid to lithium ion, battery technologies dominate the majority our our appliances, and amenities.[read more]

After a prolonged development program and costly production delays, Boeing started delivering its latest state-of-the-art airplane just 15 months ago, three years behind schedule. Although the company has a lucrative backlog of nearly 800 787s on order, worth roughly $200 billion in revenues, production rates have been limited, as only 50 units have been delivered in a little over a year.[read more]

Researchers Discover ‘Crushed’ Silicon Increases Battery Life

November 5, 2012 by Nino Marchetti

Normally, when a scientist spends a good portion of their life in a lab, trying to engineer a technological breakthrough, the last they want is to see that work destroyed. But as researchers at Rice University recently discovered, crushing their previous work can sometimes be the only way to make progress.A Rice team has been trying...[read more]

ARPA-E Director Majumdar: America Must “Out-Innovate” Foreign Competitors

October 14, 2011 by Silvio Marcacci

America pioneered many of the clean energy technologies now being used and manufactured around the world, but the edge we once held in clean tech is slipping to foreign competitors. Five years ago, scientists warned the U.S. was falling behind other nations and Congress responded by creating the Advanced Research Projects Agency, or ARPA-E, to help fund the development of breakthrough energy technologies. Now, this initiative faces political headwinds and the U.S. risks any momentum gained since ARPA-E was founded. In this one-on-one interview, ARPA-E Director Arun Majumdar discusses the energy challenges America faces from other countries and how the U.S. must “out-innovate” its competitors to spur new economic growth.[read more]

Hybrid Locomotives + The Batteries They Need
