The installation of a weight on the Keystone oil pipeline in South Dakota upon its construction in 2008 appears to have caused mechanical damage to the coating, leading to a recent rupture and oil spill.

Researchers have developed an alternative, less expensive anode material for alkaline water electrolysis, which they say promotes less carbon corrosion. The researchers say their new nanostructured catalyst can reduce the rate of carbon-induced corrosion often experienced in alkaline water electrolysis, used to produce hydrogen from renewable resources.

Steel structures such as bulkheads, piles, offshore drilling platforms, etc., may be protected with either sacrificial galvanic anode or impressed current cathodic protection systems.
