US Navy Set to Lauch Floating Macro Micro Grid


You can do a lot with 78 megawatts, including power 26,000 homes, for instance. Or you use it to run absolutely everything on one of the Navy's newest warships.

I'll let IEEE explain:
The Zumwalt’s propellers and drive shafts are turned by electric motors, rather than being directly attached to combustion engines. Such electric-drive systems, while a rarity for the U.S. Navy, have long been standard on big ships. What’s new and different about the one on the Zumwalt is that it’s flexible enough to propel the ship, fire railguns or directed-energy weapons (should these eventually be deployed), or [all] at the same time.

Farrell says Stay the Course on DOD Energy Diversification

With the rash of stories this past year on failures of US solar companies, the lack of speedy adoption of electric vehicles, and the boom in un-conventional natural gas and oil, occasional readers of the DOD Energy Blog might wonder whether renewables and energy efficiency have lost some of their luster for operational and facilities energy applications.

Well, the June edition of National Defense leads with a piece called "New American Oil Boom: "Will it Slow DOD's Renewable Energy Momentum?" which convincingly refutes the idea that energy leaders have taken their eye off the alternative energy strategy ball. National Defense magazine has long had a strong focus on energy matters, thanks to the leadership and insight of its President, retired USAF General Larry Farrell.

Reminding us of how tightly bound the DOD remains to oil, Farrell says:
When speaking of petroleum, independence is a myth, regardless of where it comes from. The fact is that, for transportation energy, there is no diversity of supply or source.
And looks a few years into the future:
Diversity has strengths of its own. The current positive situation of domestic supply will last a few years at best — perhaps out to 2030 or so. At some point global demand and increasing difficulties to get supplies will catch up. 
Concluding with a vote of confidence that DOD leadership is still on point on energy strategy:
We have the gift of time to address the problem. Knowledgeable leaders in the Defense Department realize this. It is unlikely that they will slacken their efforts to bring solutions to operational capability. There really is no other choice. 
I believe Farrell's observations and conclusions are correct, but Dan and I would be happy to hear if you see things the same way.  Andy Bochman

Army Goes Electric

Just got off a Pentagon Bloggers' Roundtable call with the Army's Senior Energy Executive, Paul Bollinger. Primary purpose was to announce the lease of 4,000 neighborhood electric vehicles (NEVs) for use on CONUS Army installations, each one replacing a standard gasoline powered sedan. Partners include the General Services Administration (GSA) and Global Electric Motorcars (GEM), a Chrysler company based in Fargo, ND. Here are the highlights:
  • Cars go 25 MPH which is fine for most bases
  • Recharge at standard 3 prong, 110 V outlets
  • Army also investigating higher speed electric vehicles for longer distance and off base use
  • May be able to replace a total of 28,000 Army vehicles
  • Large savings on along every vector: lease costs of vehicles, maintenance and fuel. Click here for electric vs. gas powered GSA fleet comparison
Lastly, Mr. Bollinger revealed this nugget towards the end of the talk: the Navy is inquiring about a similar electric car action for is bases and the Air Force may not be far behind. Were both to follow in the Army's footsteps, we could be looking at a DOD total of 50,000 cars. Now that's what I call making a market !!!
