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…)
A U.S.-based company says it has developed a new lithium-ion battery with an energy density of 400 watt-hours per kilogram — roughly twice the density of existing rechargeable batteries — an innovation the company claims could significantly increase the range of electric cars and ultimately cut the price of battery (more…)
It’s December again (how did that happen!?) and our annual time for reflection here at Kachan & Co. So as we close out 2011, let’s look towards what the new year may have in store for cleantech.
There are eggshells across the sector for 2012. Global economic uncertainty in particular is leaving (more…)
