Potential Cost savings examples
Example 2 - Typical small courier business
- Fleet: 30 x van (additional cost of CNG van £2k each)
- Mileage: 30,000 miles/yr
- Fuel consumption: 20 mpg
- Filling profile: One fill per vehicle per day (fast-fill) between 6am-6pm
The gas station would be sized for this total load requirement and this daily gas load.
For this example we have a daily gas load of 535 Kgs therefore the compressor capacity requirement is 54 Kgs/hr (for a 10 hour run). This in practice would be done using two compressors each sized at 27 Kgs/hr.
Suitably sized gas storage and two gas dispensers would also be installed.
For this example a typical all-in gas price would be in the region of 85 p/Kg.
Existing diesel costs (based on 45,000 gallons diesel, 90 p/lit) = £184k (£920k over 5 years)
All-in gas price (station, fuel, service etc.), based on 85 p/Kg & 160,000 Kg/yr = £136k (£680k over 5 years)
Fuel saving = £48k (£240k over 5 years)
Additional cost of 30 CNG vehicles (at £2k each) = £60k
Total 5 year saving (station, fuel, service & vehicles) = £180k
Above figures exclude any additional savings due to reduced VED rates, any congestion charge savings, or any grants that may be available.
