Methane gas is not normally considered for emergency standby applications. Whilst being cheaper to run on gas, the fuel saving will never cover the almost double the price of the gas generators compared to diesel generators.
Gas power is being seen as an alternative to utility power:
- Gas is substantially cheaper than diesel
- Methane gas has low emissions with today’s lean burn engines
- Waste heat recovery can raise the efficiency of continuous duty generators from ± 40% to +94%. The captured heat can feed tri-gen equipment and literally replace all heating and refrigerant loads in a building
- Major maintenance costs can be amortised over +60 000 hours compared to diesel units at 25 000 hours
