  • Absorbed Natural Gas 500psi filler?

    I've seen a van around that was built as a promotional tool for ANS (Absorbed Natural Gas). It has 500psi tanks. Any idea how to fill the thing up?

    I can only imagine that 500 PSI compressors would be the easiest thing to manufacture that this industry has seen in YEARS.

    Anyway, don't know where the compressors are, but you can bet your bottom dollar that as soon as the systems are available, compressors will be sprouting up like watermellons!

    Oh, and not to nit pick, but the term is actually "Adsorbed," with a d.

        Yeah, the topic of ANG comes up every few weeks, and invariably the link to that site pops up.

        The technology is there, now we just gotta get somebody to start making 'em!

          The largest tank they make holds about 1.3GGE. Maybe useful for emergencies, but that's about it.

            question. couldn't you just use the existing system on a vehicle. to fill it up and shut it off after it reaches the 500 mark. you might have to add an extra filter just in case (just speculation). and if it comes to pass that it becomes an industry standard couldn't you just back down the outgoing pressure on the existing pumps thereby keeping the pump in service longer and saving money in the end.

              I'm sure it would be possible to install a pressure regulator which would step the pressure down to 500psi.

                just thought of this today couldn't we just retrofit the existing tanks in the vehicles to use ANG if all it takes is some sort of holding agent like activated charcoal (probably not it but best description i could think of. couldn't you just take off the cap and clean it out and fill it up with said substance? that way you wouldn't have to charge them anymore money? but once again this is coming from the cheap side of things

                  This came up about 10 years ago too. The carbon/charcoal matrix inside the tanks had a finite life and would have to be rejuvenated periodically. The matrix had to be heated to release the trapped hydrogen/carbon molecules. At the time, they were VERY expensive and had about a 100 fill cycle life between matrix rebuilds. I assume that they have improved the matrix structure though.

                    As far as I understand it, the newer design is a solid piece, machined into shape, and then placed into the tank before it is domed, or otherwise sealed. It's not just some charcoal dust you can dump in.

                    The beauty of these tanks though, is that they need not be cylindrical in shape, due to the low working pressures. This means that eventually, we'll start seeing "fuel tanks" that fit in place of the OEM gasoline tanks. Tanks that fit in the wheel wells of cars, or that fit in the oddly shaped spaces under vehicles.
