There was a lot of sulfur in the gas, because of which the MT had to have lots of expensive gas cleanup equipment. The diesel engine just required frequent oil changes.

Read the article and see where they remove the hydrogen sulfide leaving 99% pure methane.

wrt Stirling Engines... I never managed to get my mind around how they work. But the diagrams are certainly elegant.

Now that I think about it, what role does the diesel play in the genset? Just a diesel engine that runs methane? I don't follow you there. Can you explain more?
