What is a Dispensing Station used for?

A dispensing station is specifically designed to provide fuel directly into vehicles, such as those running on compressed natural gas (CNG). This process involves transferring the fuel from storage tanks or containers to the fuel tanks of the vehicles, enabling them to operate efficiently. The primary function of a dispensing station is thus to facilitate the refueling process for natural gas-powered vehicles.

While the other choices mention various aspects related to natural gas, they do not accurately capture the primary role of a dispensing station. Converting CNG to LNG, for instance, is a different process focused on changing the state of natural gas rather than dispensing it as fuel. Storing excess natural gas pertains to maintaining reserves rather than the dispensing action. Monitoring emissions from natural gas is an important environmental consideration but is not related to the immediate function of a dispensing station, which is solely focused on fueling vehicles. Therefore, the correct answer indicates the main purpose of a dispensing station in the context of CNG delivery.
