The Tesla Powerwall and Disruptive Innovation

Elon Musk announced Tesla’s home/business battery today. Quick version: It’ll get enthusiastic early adopters to buy. The economics are almost there to make it cost effective for a wide market. And within just a few years, it almost certainly will be cheap enough to be cost effective for a broad market.[read more]

ARPA-E Battery Development

The Department of Energy’s ARPA-E program was created to give “blue-sky” research projects the money they need to prove whether or not they’re ready for commercialization. That includes a host of projects seeking to make batteries cheaper, smaller and more durable.[read more]

Gasoline Prices and the Battery Business

January 13, 2015 by James Greenberger

Falling gasoline and crude oil prices have ignited predictable concern about the future of renewable energy technologies and of technologies, such as electrochemical energy storage, that facilitate the use of renewable technologies on the grid and in transportation. Those concerns are misplaced.[read more]

What Will the Battery Market Look Like in 2030?

Energy Storage Internalized Costs

 

This article will gather some data about TEC community views on the global average internalized cost of using batteries as a primary energy storage mechanism. Please add your opinion so we can gather a statistically significant sample and get a meaningful indication of the consensus (or lack thereof).[read more]

Novel Bromine Battery: Small-Scale Demo, Large-Scale Promise

July 2, 2014 by Energy @ MIT

Battery and Storage Innovation

The availability of low-cost, high-capacity energy storage technology could profoundly change today’s energy landscape. The ability to store electricity when supplies are abundant and deliver it later when they’re not would permit widespread use of intermittent sources such as solar and wind.[read more]
