Energy for the War Fighter: the DOD’s Operational Energy Strategy (VIDEO)

The following was previously posted on the official White House blog by Deputy Secretary of Defense William J. Lynne III.

Seven years ago, after leading the initial campaigns in Afghanistan and Iraq, General James Mattis, now the commander of U.S. Central Command, called on the Department of Defense to “unleash us from the tether of fuel.”

Just last week on June 7th, General David Petraeus, echoed that call in a memo to all U.S. Forces in Afghanistan. “Energy is the lifeblood of our warfighting capabilities,” he said, noting that high fuel use means risks for the mission and for each Service member and civilian. “We can and will do better,” he directed.

Renewable Energy Powering Research Stations [Dispatches from Antarctica]




This is the 23rd entry in the Armed with Science series, Dispatches from Antarctica. The series features Air Force Lt. Col. Ed Vaughan’s first-hand experiences on OPERATION: DEEP FREEZE, the Defense Department’s support of National Science Foundation research in Antarctica.

19 October 2010, New Zealand’s Scott Base, Antarctica: River of Wind

[In Adelie Land, Antarctica, a howling river of] wind, 50 miles wide, blows off the plateau, month in and month out, at an average velocity of 50 m.p.h. As a source of power this compares favorably with 6,000 tons of water falling every second over Niagara Falls. I will not further anticipate some H. G. Wells of the future who will ring the Antarctic with power-producing windmills; but the winds of the Antarctic have to be felt to be believed, and nothing is quite impossible to physicists and engineers.

Decades ago, Admiral Richard E. Byrd, famed American Antarctic explorer, made the first recorded use of electricity generated by wind power in Antarctica. Between the years 1933-1955, a Jacobs Wind-Driven Electric Generating Plant, a small commercial wind turbine of the time, provided power for the Little America outpost.

Since that time, both the technology and proliferation of wind turbine technology has evolved. The Australians, Belgians, and others now make use of wind power in various stations across Antarctica. Goals of energy conservation and a move toward sustainable, clean resources are changing the face of power production here. The fierce winds of the world’s coldest continent, however, have remained relatively unchanged.

In January, at a joint New Zealand – United States ceremony on Crater Hill, the continent’s southernmost, largest wind-power station was officially dedicated. According to Antarctica New Zealand (ANZ), the three wind turbines, each rated at 333kW, may reduce diesel requirements by 122,000 gallons and carbon dioxide emissions by 1,370 tons annually.

Make Me Lighter! The Real Challenge Facing Battery R&D

Christopher Hurley is an engineer with the Army Power division of the U.S. Army Communications-Electronics Research, Development and Engineering Center (CERDEC), which is located at Fort Monmouth, N.J. Mr Hurley is manager for the Dismounted Soldier Power Army Technology Objective and specializes in energy storage devices.

The idea that batteries are not improving is untrue – over the last four decades, their energy density continues to rise. But with the increased use of electronics in sensors, communications and weapons, the dismounted Warfighter will have to carry more power sources. And this means adding weight to a load that’s already very heavy.

The challenge for improvement lies in developing safe, cost-effective power sources that are small, light, durable and that can support long missions.

As part of our goal to increase energy independence on the battlefield, CERDEC‘s Army Power division is using state-of-the-art battery chemistries to develop Command, Control, Communications, Computers, Intelligence, Surveillance, and Reconnaissance (C4ISR) batteries that are half the size and weight of current C4ISR batteries, yet provide the same runtime.

The Half-Sized BA-5590 is an alternate solution to the standard BA-5590. This new half-sized primary battery provides similar performance and runtime in half the weight and volume as the BA-5590.

Lithium Carbon MonoFluoride, or Li/CFx, is a chemistry that is typically packaged in coin cells for the commercial and medical markets. Its success in those markets and natural electrochemical properties, have made it a viable option for military applications. Li/CFx is a safe, high-energy density chemistry that offers longer shelf life, lower self-discharge rate, and excellent high-temperature performance.
