Reciprocating Engines

Reciprocating engines are generally less expensive than competing technologies. They also have start-up times as low as ten seconds, compared to emerging technologies that may take hours to reach steady-state operation. Through years of technology advancements, reciprocating engines have climbed in efficiency from under 20% to over 30%. Today's most advanced natural gas-fueled IC engines have electrical efficiencies (based on lower heating value, LHV) close to 45%.
