Winner of Million-Dollar X Challenge Cleans Up Oil Spills Three Times Better Than Existing Tech

[madokie]

Last summer, as sweet crude oil gushed unabated into the Gulf of Mexico, the overriding emotion was one of frustration. It wasn't just directed at the well owner, BP, or at rig-builders Transocean and Halliburton, or even the government and its difficult-to-understand oil flow estimates. The inability to shut off the well was one thing — but why, in an era of nanotubes and autonomous robots and invisibility cloaks, couldn't we just clean it up?

Sure, skimmer ships, containment booms and dispersants deployed immediately, aiming to capture oil gushing from the blown well beneath the destroyed Deepwater Horizon rig. But week after frustrating week, the best available technologies failed to make much of an impact. But some people saw opportunity in this disaster — a chance to prove a new idea, or maybe build upon an old concept. The Wendy Schmidt Oil Cleanup X Challenge, under the auspices of the X Prize Foundation, encouraged competitors to design new oil-removal technologies that would dramatically improve the state of the art. Today in New York, we found out just how far some friendly competition and a tidy sum can push the technological envelope.

Nearly 400 applicants were narrowed down to 10 finalist teams, who were invited to test their techniques at the nation's oil spill test bed, the Department of the Interior’s Ohmsett facility at the Naval Weapons Station Earle in Leonardo, N.J. The minimum criteria to be eligible for the prize: a technology capable of an average oil recover efficiency (ORE) of more than 70 percent—that is, the mixture extracted from the water had to be 70 percent oil—and an oil recover rate (ORR) of 2,500 gallons per minute. That’s roughly twice what the oil cleanup industry’s best technology can currently recover. The leading team was promised a $1 million reward, while second and third place would receive $300,000 and $100,000 respectively.

This morning in New York, just minutes before revealing the winners of the Wendy Schmidt Oil Cleanup X Challenge, Schmidt herself made what would prove to be the understatement of the event: “This is a powerful return on a relatively modest investment,” she said knowingly. A few minutes later we would find out just how right she was. Second place winner NOFI of Norway demonstrated technology that extracted 2,712 gallons per minute with an ORE of 83 percent. But audible gasps went up when the winning numbers hit the presentation screen. Team Elastec/American Marine had blown the competition out of the water, recovering 4,670 gallons per minute at efficiencies averaging 89.5 percent.
