Shell told MPs that in Alaska available mechanical recovery assets had "a combined capacity that exceeds the worst-case discharge potential of the well we are drilling".
According to the testing performed to date at the Ohio State University's Center for Automotive Research (CAR) and the very low observed rate of aging, cells built with A123's Nanophosphate EXT are expected to be capable of retaining more than 90 percent of initial capacity after 2, 000 full charge-discharge cycles at 45 degrees Celsius.
"BP must identify in the next 48 hours additional leak containment capacity that could be operationalised and expedited to avoid the continued discharge of oil, " wrote Rear Adm James Watson.
