Corrosion Crisis

Diesel Infrastructure Corrosion

The increased prevalence of corrosion in the diesel infrastructure was first noticed in 2007, shortly after the introduction of ULSD (Ultra Low Sulfur Diesel) biodiesel blends. In 2016, the EPA published it's research results, which found 83% of storage tanks have moderate to severe corrosion.  The main corrosion source is microbes in the fuel. Microbes produce acids as a byproduct of growth, acidifying the fuel, and corroding the diesel infrastucture.


The cost of corrosion is immense. The lifecycle of tanks is reduced, normally tanks last for 30 to 40 years, now tanks have been replaced in as little as 10 years. The cost of removing and replacing these storage tanks is huge. The increased corrosion is affecting all parts of the diesel infrastructure, piping, fittings and seals, so environmental damage, and cleanup liability, is increasing. 


Acidified fuel is damaging the injectors of emergency backup generators, putting at risk the safety and health of the public at hospitals and water treatment plants. Data centers face large liability issues if backup generators fail during a real emergency, causing disruption to business.
