Compressed Natural Gas (CNG)
● CNG is Natural Gas -
compressed and stored - for
use in vehicles (replacing
diesel / petrol)
● Require:
● Natural Gas Vehicles (NGVs)
● Refuelling equipment

Natural Gas Vehicle (NGV)
● Provides a real alternative to petrol and diesel
● Main types of NGVs:
● ‘Dedicated’ - run on Natural Gas only
● ‘Bi-Fuel’ vehicles operate on Natural Gas while retaining the ability to use petrol as a reserve fuel
● ‘Dual-Fuel Technology’ – Diesel and Natural Gas
● Ideal for fleets
● Bus, trucks and vans
● Vehicle manufacturers have proven options available
● Purpose built - directly off the production line
● Natural Gas stored in concealed cylinders
● No payload restrictions
● Proven vehicles & technology
● Over 13million NGVs worldwide
‘Normal’ refuel process
High-pressure tanks: protected by a solid
steel frame meet the high safety standards
laid down in ECE R110 and retains full
payload space

● Reduce vehicle emissions
● Local emissions
● Nitrogen Oxide (NOx)
● Particulate Matter (PM)
● Sulphur Oxide (SOx)
● Reduce Greenhouse Gas emissions
● Improve quality of air and health benefits
● Reduce noise (night time deliveries)
● Pathway to a renewable fuel source – Biomethane

Ireland’s NOx Emissions
● Ireland is required to limit annual emissions, including NOx,
under the National Emission Ceilings Directive by 2010
● EPA (Jan, 2011) reported Ireland’s NOx is 37% above the 2010
ceiling, with transport continuing to pose a significant challenge
11
● Nitrogen Oxide (NOx) ● Human health concerns
include effects on breathing and the respiratory system, damage to lung tissue, and premature deaths
● Environmental concerns include acid rain and smog

CNG provides pathway to Biomethane – Renewable Transport
13
● National target: Renewable Transport (RES-T) -> 10% by 2020
● Biomethane can form part of the solution for RES-T
● Sweden: 65% of gas used in transport comes from biomethane
● Germany: Focus on biomethane and investing in the CNG infrastructure
● 2009 12% of 850 CNG refuelling stations had 10% biomethane at the dispenser
● Aim for 20% biomethane at all dispensers by 2020
CNG can facilitate the development of biomethane industry in Ireland
