Electricity from natural gas

How is the best way to generate electricity from natural gas over the long
haul. I worry about the long term continuous duty cycle on piston engine
type generators. Is there another way?

thanks,
mike

speaking of which, can anyone point to a simple and strightforward
chart that compares, to pick a reasonable size, the efficiencies
of the different options for a one megawatt generator?

Basically im looking for how much of the theoretical
thermal energy from the fuels actually comes out
the generator side as electricty.

- gas turbine, internal combustion, and at this
size we could look at steam boilers, too, I'd guess.

I figured this would be a simple search but I ain't finding
anything useful.

Thanks

- note that I'm NOT, at this point, thinking about the
extra pseudo-efficiency from "cogenerating" and using
the waste heat for, well, heating...

THanks again

The very best way is to connect to the grid and allow your utility to do
it for you. Beyond that, until you tell us more about what you wish to
accomplish, any answer you get here will likely be useless to you.

As others have stated, more information is needed - i.e. amount of power,
cost of NG supply, etc., etc.

One option for long term durability in a much lower tech form would be an
oilfield cathodic genset. These are large bore, single cylinder, low RPM NG
engines combined with a matched genset that are designed and built for long
term, low maintainence operation. Typically used to power the cathode
protection on NG and oil transport lines in remote locations. The engines
themselves are used to operate pumps on wellheads in remote locations,
running on NG supplied directly from the well. Technology has been around
since the mid-20's...

There are some vids of "Arrow engine" on youtube as well
