Compressed Natural Gas Studies
Compressed natural gas is a cleaner, reliable and proven alternative to diesel or petrol. Please see below the list of studies that outline the financial and environmental benefits of CNG.
| Study | Findings | |
|---|---|---|
| Payback period for natural gas vehicle | Low Emissions Freight and Logistics Trial, Low Carbon Vehicle Partnership (2020) | The estimated payback period for HGV trucks is in the region of two years |
| CNG fuel cost savings versus diesel | Future of Gas, Transport, Cadent (2016) | CNG can generate fuel cost savings of up to 35% for fleet owners compared to diesel |
| GHG (CO2eq) Emissions | Cenex (2019) | Well-to-Wheel GHG (CO2eq) emissions reductions of 7% to 23% from Euro VI gas HGVs relative to Euro VI diesel equivalent depending on drive cycle and payload – the higher end of this range relates to the long-haul and regional drive cycle |
| UK Department of Transport: Transport Energy Model Report (2018) | Well-to-Wheel GHG (CO2eq) emissions reductions of 15% for Artic HGVs and 12% for Rigid HGVs | |
| Air Pollutants - NOx | Project Equilibre (2018) | Euro IV gas HGVs emit significantly less NOx relative to Euro IV diesel HGVs depending upon road type – average reduction of more than 60% observed for sections of road classed as motorway |
| UK Department of Transport: Transport Energy Model Report (2018) | NOx emitted by Euro VI gas HGVs up to 50% less than Euro VI diesel | |
| Air Pollutants – Particulate Matter (PM) | UK Department of Transport and LCVP: HGV Emissions Testing (2017) | PM emissions are low from dedicated gas vehicles, with the gas vehicles producing around 1-3 mg/kWh relative to a Euro VI limit value of 10 mg/kWh |
| IVECO (OEM) | CNG HGV reduction in PM of 99% | |
| Renewable gas options and timelines for decarbonisation of the UK HGV transport sector. | Outline of decarbonisation options for the UK transport sector including the production, distribution and use of electricity, biomethane, bio-SNG and hydrogen to understand the role of each fuel and the timeline for scaling up of their use. |
