Japan Now Has More EV Chargers Than Gas Stations

For any alternative fuel in transport, the key question is: what about infrastructure? As in, how much does infrastructure cost, what are the environmental effects, and who is actually going to pay for it? Without answering these questions, analysis of alternative fuels often becomes nothing more than an introduction to the fuel’s chemical properties. In [...]

Stanford Researchers Unveil New Ultrafast Charging Aluminum-Ion Battery

This schematic shows how the aluminum-ion battery shuttles AlCl4- ions from its graphite cathode to its aluminum anode in order to produce a discharge current (Source: Lin et al., 2015)

Last week, Stanford University researchers unveiled a new aluminum-ion battery chemistry with the unique ability to charge or discharge in less than a minute. The battery’s incredibly fast charging and discharging times are not its only breakthrough. It is also the first aluminum-based battery to achieve an operating voltage sufficient for common applications and last [...]

Wellinghoff: Extend Electricity Market Visibility to the Distribution Grid

Wellinghoff_Large

Last week I had the pleasure of attending Austin-based research firm ZPryme’s annual Energy Thought Summit, which brought together business leaders and technical experts to discuss emerging energy technologies and trends. One of the featured speakers was former Federal Energy Regulatory Commission (FERC) Chairman Jon Wellinghoff. He spoke about some potentially disruptive energy technologies currently [...]

Throwback Thursday: The First U.S. Energy Storage Plant

(Source: Popular Science via Google Books)

In July 1930, the magazine Popular Science ran an article announcing the start of operations at the first U.S. “ten-mile storage battery”—or pumped-hydro energy storage plant—near New Milford, Connecticut. Connecticut Electric Light and Power Company built the plant to meet the region’s peak electricity load and mitigate seasonal water shortages. The article goes on to [...]

Low oil prices aren’t working against solar (probably)

2013 US energy - small

In the United States, reducing electricity probably won’t lead to a significant reduction in direct oil consumption. Instead (in terms of fossil fuels) it is more likely to reduce your consumption of coal and natural gas. In turn, low oil prices aren’t necessarily working against solar deployment in a direct sense. The United States uses [...]

Software: The Next Challenge for Grid Batteries

RedBattery

It seems like every day we hear about another incremental breakthrough in battery technology. By tweaking existing battery chemistries or inventing new chemistries altogether, university researchers and startup companies have managed to increase the energy density, cycle life, energy efficiency, and safety of numerous potential grid battery technologies. There’s no doubt that these advances in [...]

Three Reasons Oncor’s Energy Storage Proposal Is a Game Changer

The Brattle Group calculated the net effect that Oncor's proposal would have on an average Texas residential electric bill.

Early last week, Texas transmission and distribution company Oncor announced a proposal to install 5,000 megawatts of battery energy storage on the Texas grid. The words “game-changing” get thrown around a lot about energy storage projects—usually prematurely. But in this case I think there are some clear reasons why Oncor’s proposed deal could be a [...]

Is NYC poised to become an energy storage leader?

new-york-14480_640

The recently announced Demand Management Program by ConEd includes significant incentives for both thermal and electricity storage technologies. If the plan moves ahead, the NYC area could be home to more energy storage than almost any other state by summer 2016. The Consolidated Edison Company of New York (ConEd) provides electric service in New York [...]

German, U.S. Home Energy Storage Incentives Offer Divergent Visions for the Smart Grid

Germany’s solar feed-in tariff not only incentivizes a homeowner to install solar panels, but also to store solar energy for later use in the home. (Photo credit: Flickr user thetimchannel)

Previously, I’ve written about the potential for a future smart grid, where homes with solar panels and batteries intelligently interconnect to form a cleaner, more-robust distributed power system. While we’re still far from a full-fledged smart grid, recent years have seen wider deployment of distributed energy storage. Today, Germany already boasts over 7,000 home solar [...]

Welcome to Texas – America’s energy storage laboratory

texas-277030_640

Texas is well-known as the home of the oil and gas industry. Over the last decade it has also become the nation’s wind power leader. Today, it is poised to be America’s testbed for energy storage technologies. The state’s image as the home of big oil and gas has been cultivated over the years through [...]
