Energy Scavenging is just one way ARL experts are getting more from existing resources, said Dr. Edward Shaffer, who is the Energy and Power Division Chief at the lab. Energy harvesting is critical to realize “net zero” energy use, a key element of the…

Duane Tilden‘s insight:

Department of Defense operational energy is an emerging area being shaped. It is what is required to train, move, and sustain forces, weapons, and equipment for military operations. It accounted for 75 percent of all energy used by DOD in 2009, according to the Energy website for DOD. It was in May 2011, when the Assistant Secretary of Defense for Operational Energy, Plans and Programs defined an operational energy strategy, and then published Operational Energy for the warfighter, a guide that would transform the way the DOD consumes energy in military operations.

Shaffer has a wide view of the energy needs across Army, DOD and interagency forums that explore complimentary ways of addressing energy and power technology gaps and reduce duplicated efforts, including the DOD Energy and Power Community of Interest and the Interagency Advanced Power Group that includes agencies like the Department of Energy and NASA. These communities are comprised of scientists, engineers, subject matter experts, technologists and program managers with a common interest in promoting innovative energy and power solutions for the nation.

At ARL, the future is a seamless energy architecture that begins with concepts like SmartBED, Long-lived Power and Fuel-Reforming for better energy convergence.

April 25, 2013 – NEMA endorsed HR 1465, STORAGE 2013, which promotes adoption of state-of-the-art energy storage technologies, calling this legislation “carefully crafted” in its regard for entire range of energy storage technologies. …

Duane Tilden‘s insight:

“Energy storage is a key enabler of the Smart Grid and is transforming the way we think about electricity,” said NEMA President and CEO Evan R. Gaddis. “By getting us beyond the need to generate electricity at the same moment as it is used, energy storage delivers greater system efficiency, enhances reliability and resiliency, and fosters integration of renewable energy.”

STORAGE 2013 would offer a 30 percent investment tax credit for energy storage used in connection with the power grid, with no project eligible to receive more than $40 million, and the total program capped at $1.5 billion. For municipal utilities and electric cooperatives, the legislation would make energy storage eligible for new clean renewable energy bonds. To promote efficiency and distributed generation in the commercial and residential markets, the bill offers a 30 percent credit (up to $1 million) for onsite application of energy storage.

Researchers from the U.S. Department of Energy’s (DOE) SLAC National Accelerator Laboratory and Stanford University have managed to design a low-cost, long-life battery that could enable solar …

Duane Tilden‘s insight:

The new Stanford/SLAC battery design uses only one stream of molecules and does not need a membrane at all. Its molecules mostly consist of the relatively inexpensive elements lithium and sulfur, which interact with a piece of lithium metal coated with a barrier that permits electrons to pass without degrading the metal.

When discharging, the molecules, called lithium polysulfides, absorb lithium ions; when charging, they lose them back into the liquid. The entire molecular stream is dissolved in an organic solvent, which doesn’t have the corrosion issues of water-based flow batteries.

“In initial lab tests, the new battery also retained excellent energy-storage performance through more than 2,000 charges and discharges, equivalent to more than 5.5 years of daily cycles,” Cui explained.

SANTA MONICA, Calif., April 18, 2013 /PRNewswire/ — SolarReserve, a leading U.S.-based solar energy developer; today announced the company’s international expansion into the Latin American region through the opening of its office in Santiago, Chile.

Duane Tilden‘s insight:

SolarReserve’s industry leading CSP technology features an integrated molten salt energy storage system, allowing firm, reliable electricity to be generated on-demand and delivered when the client requests the electricity. This energy storage capability provides a stable electricity product similar to that of conventional fuel-burning power facilities, but without the associated harmful emissions and price volatility.

Engineered and proven by Pratt & Whitney Rocketdyne, the technology generates power from sunlight by focusing energy from a field of sun-tracking mirrors called heliostats onto a central receiver. Liquid salt, which flows similarly to water when melted, is circulated through the receiver, collecting the energy gathered from the sun. The heated salt is then routed to an insulated storage tank where it is stored with minimal energy losses. When electricity is needed, the hot salt is routed to heat exchangers to produce steam that is then used to generate electricity in a conventional steam turbine cycle. Therefore, the system minimizes risk, time and cost, while providing high capacity storage that allows energy production on-demand, day or night.

Duane Tilden‘s insight:

Green jobs are growing four times faster than the rate of all other jobs nationwide, with the majority happening in California according to the Bureau of Labor Statistics. EDF’s analysis of California’s clean economy finds that jobs in core sectors like energy efficiency, renewable energy, clean transportation, and advanced storage and materials have not only remained resilient during the worst of the Great Recession (2008-2010), they outpaced all other job growth and grew 109 percent from 1995 to 2010.

Green jobs are also good jobs in California. They are diverse, across a wide range of education-level and skills, and almost half of all jobs in the clean economy don’t require a college degree according to the Brookings Institution. On average, green jobs offer a higher median wage and career advancement opportunities. An analysis by Philip Romero, the former Dean of CSU Los Angeles College of Business and Economics finds that “workers command wages with a 50-to-100 percent premium over the average job,” and estimates that the overall clean economy will grow “by at least 60-to-100 percent” by the late 2030’s.

Energy Storage Series: Why We Need It, And Why We Don’t

See on Scoop.it – Green Energy Technologies & Development

It’s almost a cliché that there’s a “friendly debate” pitting utilities against renewable energy. But concerns on the utility side of the table are real: intermittency, potential destabilization at the feeder level, non-baseload, and peaks in generation that don’t necessarily match demand peaks. Today’s power infrastructure involves unpredictability in both supply and demand that is extremely difficult to manage.

Duane Tilden‘s insight:

The big question in energy storage, Wheaton says, boils down simply: what does it cost to build more generation (to oversupply), vs. how to store and manage energy? Today it’s more “economically rational” to build more generation, whether it’s solar or wind or even coal, he noted. As energy storage technology costs come down — and as there is better understanding and calculation of externalized costs, such as societal impacts — “we will see those lines cross, and more utilities will go to energy storage as a more economical means to serve the grid.”

Fundamentally, economics determines the decision of over-generation vs. energy storage; right now “either energy storage is not cheaper, or the payback is not enough to shift over,” noted Luebbe. As the cost (dollars per kilowatt-hour) come down and energy storage costs intersect with those in over-generation, “then everyone will do it because it’s economically the logical thing to do.”
