Toward a 'Green Grid' for Delivering Solar and Wind-Based Electricity

ScienceDaily (Apr. 17, 2011) — After years of neglect, scientists and policy makers are focusing more attention on developing technologies needed to make the so-called "green grid" possible, according to an article in ACS' Chemical Reviews. That's the much-needed future electrical grid, an interconnected network for delivering solar and wind-based electricity from suppliers to consumers.

Zhenguo (Gary) Yang and colleagues point out that concerns over the use of coal, oil, and other fuels that contribute to global warming and are in limited supply, have spurred interest in generating electrical energy from clean, renewable resources such as solar and wind power. But solar and wind are not constant and reliable sources of power, since wind power fluctuates from moment to moment and solar power is generated only in the daytime.

This situation poses a significant challenge for electrical grid operators because other power plants need to compensate for this variability and the U.S. power grid currently has little energy storage capability. To enable a significant level of penetration and effective use of renewable energy sources amid growing energy demands, electrical grids of the future will need a low-cost, efficient way to integrate and store this electrical energy, the scientists note.

The scientists analyzed the conclusions of more than 300 scientific studies and identified several technologies that can be used for energy storage for the green grid. These include high-tech batteries now in development that can efficiently store electricity in the form of chemicals and reversible release it on demand. Among the promising technologies are so-called redox flow and sodium-ion batteries, which could provide a low cost, high efficiency way to store energy. In addition to the United States, several other countries such as China and countries in Europe are planning to increase research activities related to energy storage and development.

"The growing interests as well as worldwide research and development activities suggest a bright outlook for developing stationary energy storage technologies for the future electric grid," the article concludes.

In Close Vote, House Passes Climate Bill
Measure Aims to Change Energy Use

The House narrowly passed an ambitious climate bill yesterday that would establish national limits on greenhouse gases, create a complex trading system for emission permits and provide incentives to alter how individuals and corporations use energy.

The bill passed 219 to 212 after a furious lobbying push by the White House and party leaders won over farm-state Democrats who had complained that it was too costly, and liberals who wondered if it was too watered down to work. Even after that effort, 44 Democrats voted against the legislation.

DOE Announces Up to $7 Million for Technology Commercialization Acceleration


WASHINGTON – DOE Principal Deputy Assistant Secretary for Energy Efficiency and Renewable Energy John Mizroch today announced the availability of up to $7 million to accelerate the movement of clean energy technologies from DOE’s world-class national laboratories to the marketplace. The funding will help post-research technologies move toward commercial viability by providing pre-venture capital funding for activities such as prototype development, demonstration projects and market research.

Intel cuts electric cords with wireless power system

SAN FRANCISCO (AFP) – Intel on Thursday showed off a wireless electric power system that analysts say could revolutionize modern life by freeing devices from transformers and wall outlets. Intel chief technology officer Justin Rattner demonstrated a Wireless Energy Resonant Link as he spoke at the California firm's annual developers forum in San Francisco.
