For natural gas, there are essentially two types of backup generation. Both portable and standby generators, if configured, can use natural gas as a fuel source. However when looking at generators that use natural gas, the typical configuration that comes to mind is standby generators.
The main reason for this, is that while some portable generators run on natural gas, standby generators are fixed and therefore easily tied into the home natural gas service.
This is important for a couple of reasons. To start with once the generator is installed, there is little reason to deal with the natural gas connection.
Natural Gas Vs. Propane Vs Gasoline
Where natural gas excels is the fact that if it is connected to the house main it offers an almost unlimited run time. It is true that gasoline comparatively produces more power per unit. Meaning that one gallon of gas is the equivalent of 1.36 gallons of natural gas. The same with propane, however the run time is longer due to a commercial connection, i.e. the home versus a portable tank like gas or propane.
It is further true, that some portable generators can connect via a quick connect/release mechanism to the house gas line, it represents a potential failure point during use and therefore is more dangerous compared with the standby generator connection. So, essentially that is why these are all standby generators being reviewed instead of the portable ones.
