Adsorbed Natural Gas (ANG) is a technology that’s been around for a while but has been getting more attention for the obvious reason that gasoline prices are forcing us to look at alternatives and I wondered recently which technology would eventually win. ANG conversions for motorcycles are interesting because they can be used to convert 2 stroke engines, as well as 4 strokes, over to this cleaner burning alternative.
Adsorbed natural gas is the technology that uses a filler material inside the gas canisters that allows it to hold more natural gas at the same pressure or the same amount at a lower pressure. Although most of us are familiar with compressed natural gas (CNG), the cylinder pressures (200-250 bars) involved make some folks a little nervous, even though the cylinders are very safe. Fill that cylinder with the right material and you can lower the pressure (30-70 bars) and still have the same amount of natural gas. Even better, with the lower pressures involved, you can use other shapes besides cylinders which obviously makes fitting them into odd places a lot easier. Liquefied Natural Gas (LNG) is even more difficult to handle than CNG.
One company, Energtek, Inc., has just announced a plan to power motorcycles in Asia with ANG, the only modification necessary is a $200 conversion. The ANG is stored in canisters that can be swapped out in less than 1 minute. To work on a large scale, natural gas filling stations would be necessary to stock the containers so someone can pull up and purchase a full one for the swap, something which should not be too difficult to set up, certainly easier than setting up a CNG refueling station.
I’ll be watching this develop, it sounds like it has a lot of potential.
