By spending years in the flywheel industry, Jim Fiske learned a great deal about grid-scale energy storage and its true requirements. After determining that flywheels were not the best option, he and the investor of his flywheel company founded Gravity Power. Gravity Power’s technology has the potential to change energy storage worldwide. (more…)
Efficient energy storage is key because we need to be able to access power when the sun is not out and the wind is not blowing.
About one fifth of the world’s population lacks access to electricity. It is one of biggest economic obstacles for people in developing countries, but one that could mean opportunities for a clean energy beginning with alternative energy. (more…)
One of the most promising aspects of energy storage is that it’s used to make an existing system more efficient. If you think of the grid as the system, then energy storage can help make generation, transmission, distribution, and even customer energy use more efficient.
How many different systems are there? The grid is the (more…)
This month’s issue of Wired magazine includes a long feature, written by Washington Post national environmental reporter Juliet Eilperin, headlined “Why the Clean Tech Boom Went Bust.” (Disclosure: I’m a contributing editor at Wired, and Eilperin is an acquaintance.) The story, which joins a lengthening list of obits for the cleantech industries, has a certain (more…)
Renewable energy such as solar has a basic problem: No sun , no power. In order to make it more usable the Power must be stored for off peak use when the sun does not shine. Batteries though die when repeatedly recharged. Stanford researchers have developed part of better battery, a new electrode (more…)
