Damn the deniers, the doubters, and the do-nothing Congress. The Pentagon is moving full green ahead.
I’m strapped into my backward-facing seat on a COD, or “carrier onboard delivery” plane, the US Navy workhorse that ferries people, supplies, and mail to and from its aircraft carriers at sea. I cinch the four-point harness holding me in place. Then I cinch it some more. When it’s as tight as it can go, an aircrewman walks by and yanks it so hard it squeezes the breath out of me. The hatch closes. Steam rises from the floor. I’ve watched the YouTube videos. I know what’s coming. Takeoff, a 30-minute flight, then landing on the USS Nimitz, decks pitching, plane wings waggling, tailhook dangling from the underside of the aircraft to catch one of four arresting cables stretched across the flight deck. Since it’s not hard to miss them all, the pilot will gun the engines at landing to enable an immediate relaunch. Which means that if he succeeds at trapping a cable we’ll decelerate from 180 nautical miles per hour to zero in about one second.
To get to the Nimitz, 100 miles off Honolulu, our turboprop is flying a 50-50 blend of biofuel and standard JP-5 shipboard aviation fuel. The biofuel is made from algae plus waste cooking oil. This makes us part of history, my aircrewman says, players in what the Navy calls the Great Green Fleet demonstration of July 2012. It’s paired with a three-year, $510 million energy reform effort in conjunction with the departments of Agriculture and Energy as part of a larger push to change the way the US military sails, flies, marches, and thinks. “As a nation and as a Navy and Marine Corps, we simply rely too much on a finite and depleting stock of fossil fuels that will most likely continue to rise in cost over the next decades,” announced Navy Secretary Ray Mabus at the launch of the program back in 2009. “This creates an obvious vulnerability to our energy security and to our national security and to our future on this planet.”
The Navy has set five ambitious goals to reduce energy consumption, decrease reliance on foreign oil, and significantly increase the use of alternative energy. Part of one target is to demonstrate a Great Green Fleet by 2012, and that’s what’s sailing this July day in Hawaii’s cobalt-blue waters: a carrier strike group comprising an aircraft carrier, two guided-missile destroyers, a guided-missile cruiser, and an oiler. All are running at least partially on alternatives to fossil fuels: the Nimitz on nuclear power, the other ships on that biofuel-diesel blend. The 71 aircraft aboard–Super Hornets, Hornets, Prowlers, Growlers, Hawkeyes, Greyhounds, Knighthawks, and Seahawks–are burning the same cocktail as my COD. All of today’s biofuels are drop-in replacements for marine diesel or aviation fuel and are designed to run without any changes to the existing hardware of ships or planes. “No [nation] can afford to reengineer their navies to accept a different kind of fuel,” Vice Adm. Philip Cullom, deputy chief of naval operations for fleet readiness and logistics, tells me.
