Trojane Solar Power, Not Your Average Green “Donut Shop”

Benji Jerew — Wed, 14 Jan 2015 17:06:19 +0000

To call Trojane a simple “donut shop,” as if it were merely another Dunkin’ Donuts, wouldn’t be fair, because Trojane produces a world-class confection. Also, because Trojane is solar powered, it deserves special mention here on The Green Optimistic. Like most “donut shops,” Trojane produces donuts, or “doughnuts,” depending on spelling convention, some 5,000 per […]

Metal-Free Organic Battery Technology Promises Cheap Renewable Energy Storage

Mila Luleva — Mon, 13 Jan 2014 13:25:27 +0000

The main obstacle that prevents renewable energy from being the one and only source of power is storage. Researchers have long been trying to find the key ingredient, which gives this extra boost to existing battery technologies, while it saves money on expensive materials, but it seems there is always just a little bit more […]

Molten Salt Battery Company Changes Name to Ambri, Seeks to Revolutionize Grid Storage

Ovidiu Sandru — Fri, 31 Aug 2012 18:50:33 +0000

If you remember, there was a certain company founded by a certain Professor Don Sadoway, who invented a molten salt battery designed specifically for the power grid. The battery had two liquid metal electrodes with molten salt as the electrolyte. Well, now the company renamed itself to Ambri, and is being backed up by Bill […]

Chinese Automaker BYD Unveils World's Largest Battery for Renewable Energy Storage

Ovidiu Sandru — Mon, 09 Jan 2012 20:27:19 +0000

BYD is already being known as China’s main producer of electric cars. They also produce their own ferrous batteries for the cars, which they now use to store wind and solar power in what represents the world’s largest renewable energy storage based on batteries. Having the size of a football field, the huge battery bank […]

Fulvalene Diruthenium Studied As Alternative To Molten Salts For Renewable Energy Storage

Ovidiu Sandru — Wed, 27 Oct 2010 17:43:04 +0000

Storing energy is almost as important as producing it, because wind and solar have the property of being intermittent sources - either they produce in excess or lack completely. Molten salts are currently the most used solution for storing energy in the form of heat, but they sometimes tend to be expensive and not so efficient.

Jay Whitacre’s New & Cheap Sodium-Ion Batteries Funded by DOE

Ovidiu Sandru — Fri, 11 Dec 2009 17:38:02 +0000

Sodium is several orders of magnitude more available than lithium, and that makes it cheaper to use in batteries. Taking into account the destination of the projected batteries, to act like a buffer for storing renewable electricity, low voltages are enough, so making the technology cheaper by using a water-based electrolyte wasn't hard to think of.
