Chrysler developing all-new CNG storage tank technology

  • 13-Nov-2013 11:29 EST

The large cylindrical pressure tanks typically used for onboard CNG (compressed natural gas) storage are notorious for compromising passenger and cargo volume in light-duty vehicles. Chrysler is exploring the idea of using multiple smaller tanks to conquer the packaging challenge. Its patent-pending tank design features an all-new internal configuration that enables greater storage capacity and a non-cylindrical exterior form, while capable of handling typical gas pressures up to 3600-psi (248-bar). The aim is to create CNG pressure tanks that can conform to different vehicles' chassis and body layouts, similar to current liquid-fuel tanks. Chrysler Group’s R&D work on the new tank is supported in part by a $50,000 grant from the Michigan Economic Development Council’s Technology Innovation Challenge.
