Compressed Natural Gas Studies

Compressed natural gas is a cleaner, affordable and proven alternative to diesel or petrol. Please see below the list of studies that outline the financial and environmental benefits of CNG.

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.  The future role of gas in transport, Cadent 2021 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.
