The building was used by an alternative-energy business that extracted hydrogen from water. Apparently no fire, just a huge blast that knocked out windows form the building and cars.
Two compressed natural gas cylinders were found inside the building, and officials are investigating whether the process sparked the explosion, according to Humphrey.
The exact cause of the blast has not yet been determined.

What is the name of the company where the blast occurred, there’s also some confusion about the other locations that apparently are owned by the same company in Ventura and Simi Valley where other blasts occurred in 2008 and 2010.
