Investment Has Become the Most Common Strategy for Energy Storage Integration, According to Navigant Research
Barbara Haislip for the Wall Street Journal: Few industries are more daunting for entrepreneurs these days than clean energy.
Developing the technology and hardware is expensive, and setbacks are common. Even if all goes well, getting a product to market can take a decade or more. Most venture-fund investors, meanwhile, want a quicker payout.
Danielle Fong, co-founder and chief scientist of LightSail Energy, is trying to keep investors happy while working toward some ambitious clean-energy goals. Her company’s aim, she says, “is to produce the world’s cleanest and most economical energy-storage system” through a technology that uses compressed air to store energy from the grid. LightSail’s technology will do this more efficiently than other solutions, Ms. Fong says, by capturing some of the excess heat that comes when compressing air. “Until now, this was wasted, reducing efficiency,” she says.
Founded in 2009, Berkeley, Calif.-based LightSail has raised $70 million from several investors, including Bill Gates, Peter Thiel,Khosla Ventures and the French energy giant Total. Cont'd...

India Smart Grid Week: Conference to discuss Potential of Smart Grids Towards Resolving India's Energy Crises
By Tereza Pultarova for E&T: German researchers have developed a new carbon-based active material that can be manufactured from apple leftovers and used to build better energy storage systems.
The apple-based material can be used as the negative electrode in sodium-ion batteries, which are currently being researched as a more environmentally friendly and cheaper alternative to lithium-ion batteries.
Instead of energy-intensive lithium mining, which frequently damages the environment, battery manufacturers in future could be using organic waste to make batteries.
In tests, the new material discovered by researchers from the Helmholtz Institute Ulm of Karlsruhe Institute of Technology, has demonstrated ‘excellent electrochemical properties’, allowing the researchers to carry out 1000 charge and discharge cycles during which the apple-based battery demonstrated high stability as well as capacity.
