First Adsorbed Natural Gas (ANG) powered motorbike completes successful test
You might wonder what's ANG. Energtek has a definition which gives us a hint: "Natural gas stored in a nanoporous material (usually carbon derived) at lower pressure than compressed natural gas. The advantage of ANG is that the fuel can be stored at a higher density." Please note that it's adsortion (not what a sponge does), which is "a process that occurs when a gas or liquid solute accumulates on the surface of a solid or, more rarely, a liquid (adsorbent), forming a molecular or atomic film (the adsorbate)."
Typical CNG tanks store gas at 200 bars, whereas ANG tanks keep it between 30 and 70 bars. This allows for a reduction in the cost of tanks and in the infrastructure costs of filling stations. A second important benefit is that it allows tanks to be built with different shapes, which translates into a greater adaptability for vehicles.
Energtek hopes to sell to Asian markets, where two and three wheel vehicles are predominant.
