Trees go high-tech: process turns cellulose into energy storage devices

The new approach just discovered at Oregon State can produce nitrogen-doped, nanoporous carbon membranes - the electrodes of a supercapacitor - at low cost, quickly, in an environmentally benign process.

Finding Solutions For Battery Sulfation Issues In Renewable Energy Applications

While the recent news about carbon has been touted as something that can drastically improve the overall performance of the flooded lead acid battery, the facts should be completely understood before buying these types of batteries with any carbon additives, especially if they are sold as a value added feature.

The Integrated Grid

Excerpts from the EPRI Study on the Integrated Electric Grid

GreenStation Energy Storage Powered by Smart Grid Technology

The bottom line is that energy (kWh) is no longer the cost driver for commercial and industrial electric ratepayers; power (kW) is where the pain lies.

Grid Parity: A Foggy Signal for Solar Maturity

What we can expect to see is a gradual transition of solar from an alternative energy to a truly cost competitive source of energy that helps counteract rising electricity rates and fuel costs.

States Keeping U.S. at Fuel Cell Forefront

The report identifies the "Top 5 Fuel Cell States" - California, Connecticut, New York, Ohio, and South Carolina.

NY Working Hard to Catch Up with CA's Energy Storage Requirements

Next up at the plate as a hot, receptive market for energy storage in North America is New York.

High-voltage Battery Simulator and Test Systems Critical for Electric and Hybrid Vehicle Development

Essential for conducting R&D, performance and durability testing

The Business Case for Fuel Cells - Power Reliability and Savings

More than 88 megawatts (MW) of stationary fuel cells have been installed or ordered by U.S. businesses and utilities.

VOTO - Charging Batteries in a Fire

One half of the VOTO is a fuel cell and the second half is a handle which has a light, cell phone adapter and nickel-metal hydride battery to store energy.

Vanderbilt Proposes Building Energy Storage Into Solar Cells

Imagine a photovoltaic cell or module that actually stores as well as produces energy, acting as a battery and producing power even after dark.

Will You Survive Solar Grid Parity?

A path to ensure profitable installation for residential solar

Shaw Lynds, Senior Research at Maxwell Technologies, Inc Explains Ultracapacitors

In general, ultracapacitors are great solutions whenever the power demand is high, but the duration is short. For example, we are expanding into the diesel truck market, where the high power demand of engine starting can place a great strain on the batteries, greatly lowering their useful life.

Adding the battery back-up power option to existing grid-tied PV/solar systems

Using battery-based off-grid technology, a smarter type of "grid/hybrid" inverter technology is able to use PV, wind, hydro-electric and other renewable DC energy sources to keep the batteries charged and sell the excess to the grid, just like the grid-tied unit using the grid as its battery.

Paradise Off the Grid

Residents of a small town in Baja California live off-grid using solar power, and enjoy a lifestyle that continues to attract new homeowners.
