Ask an engineer: grid-level battery storage

Robert Fares Photo_200px

We’re holding a live Ask Me Anything (AMA) on Twitter right now with Robert Fares, PhD student in Mechanical Engineering at UT Austin, about his research in grid-level battery storage. Follow along with #AskUT and @davidwogan @robertfares @zaragozaaustin. Update: I’ve embedded the discussion below. .@RobertFares Your study explores using batteries to balance the power grid [...]

Imagine There’s No Garbage. I Wonder If I Can.

In the U.S. we throw away about 70% more garbage per person than in Sweden.

In John Lennon’s iconic song “Imagine,” he paints a world without war, greed or hunger. I’d like to add garbage to his list. Yup, plain ol’ trash. It’s everywhere. It’s persistent, and as the name implies, it’s dirty. When scanning the globe to check out ways different countries address this problem, I pause at Sweden. [...]

My computer recharged because I wrote this blog…

…well, not exactly. But, it could happen soon thanks to a nanogenerator created by Dr. Zhong Lin Wang and his team at the Georgia Institute of Technology in Atlanta, Ga. Watch my short video to see how. Video: Shannon Alderman: Producer/Editor. Robynne Boyd: Writer/Editor

Tax credits – the wind in wind energy

For wind power, 2011 was a great year. California added more new wind energy to the grid than any other state, according to a report published Tuesday by the U.S. Department of Energy. A number of other states received high honors as well. These include Illinois, Iowa, Minnesota, Oklahoma and Colorado, which churned out at [...]

CalCharge – Building a Battery Innovation Ecosystem

XBD201105-00683-08.TIF

A new public-private partnership was announced today between CalCEF and the U.S. Department of Energy’s Lawrence Berkeley National Laboratory. The goal of this new partnership – dubbed CalCharge – is to create a regional ecosystem to spur innovation in energy storage (battery) technologies. This group will bring together private technology companies, academic institutions, and government [...]

Energy Storage – For More Than Renewables

ElectricityStorage

Large-scale energy storage technologies are often hailed as a key to enabling increased use of intermittent renewable energy resources – like solar and wind – to supply the nation’s electricity demand. If one can balance out the generation dips (for example, when the wind dies down on a summer afternoon) using an energy storage technology, [...]

Light on Landfills: Solar energy covers turn maxed-out landfills into solar farms

Hickory Ridge landfill outside of Atlanta, GA, is full. Like most landfills that reach capacity, it was capped to contain its noxious mix of debris that will slowly degrade over the decades and centuries to come. But unlike most, Hickory Ridge glistens on a sunny day due its over 7,000 thin-film photovoltaic solar panels plastered [...]

Molecular-Level Energy Storage

483756270_2f2f1c3d3c_z (1)

When the sun dips below the horizon for the night, most solar panels become interesting roofing tiles, instead of valuable generation resources. During the day, a single cloud can quickly send residential solar power generators back to a fossil fuel-based grid for their electricity. This intermittency in fuel resource availability, combined with the current lack [...]
