    Don't worry, if CNG cars and trucks start becoming popular here, every minor incident will also be national news.
    The reports may even get the details wrong, as seems to be happening in Pakistan.
    "It was surprising that electronic and print media persisted in erroneous reporting that the accidents occurred due to bursting/explosion of the CNG cylinders. Add to that, some of the Government departments were also relating these accidents to non-compliance of Hydrostatic testing of CNG cylinders. Both are absolutely wrong impressions. This incorrect reporting has continued to date which has developed serious apprehensions about CNG cylinders in general public."

    I'm not worried.
    Properly designed and installed cng storage systems are safe. Research into even better ones is ongoing ... i.e.:

    Now if I went back in time 8 years and was riding around in a hacked together CNG crackerbox cab in Karachi -- put together with whatever could be found in the local trash heap? ... I might be a little worried.

    /good thing hydrogen isn't cheap and readily available in Pakistan, .. the whole country might be one rolling inferno.

    I'm not either.

    But if CNG cars become the next new thing, incidences that are regular place for cars and trucks will become national news when they are involved. Regardless of whether or not they are actually a higher risk.

    A Camry hybrid with one of these engines would likely use less natural gas than a Mirai.

    "UPS Inc. announced it will spend $450 million to add 6,000 vehicles powered by compressed natural gas as well as supporting infrastructure beginning next year. It is the largest multiyear commitment UPS has made to date for alternative fuel vehicles.



    The additions include heavy-duty trucks, medium-duty package vans, and terminal tractors.

    UPS expects to have finished adding the equipment by 2022.

    “We have been deploying natural gas vehicles for many years. We greatly accelerated our deployment of natural gas stations and vehicles starting in 2013. We no longer consider our natural gas fleet to be in a test or experimental phase, but rather it is mainstream for UPS now,” a UPS spokesperson told Transport Topics. “We closely follow oil and natural gas prices, but we believed back in 2013 that natural gas in the U.S. would be relatively stable in cost versus oil-based fuels. That has proven to be the case and we see that continuing for the foreseeable future.”

    “UPS notes that the CNG fleet expansion provides additional capacity for expanding the use of renewable natural gas (RNG). Vehicles equipped with CNG fuel systems can interchangeably use RNG and conventional natural gas. Produced from landfills, dairy farms and other bio sources, RNG yields up to a 90% reduction in lifecycle greenhouse-gas (GHG) emissions when compared to conventional diesel. As of October, UPS has agreed to purchase 230 million gallon equivalents of RNG over the next seven years, making it the largest consumer of RNG in the transportation industry, UPS claims.”
