Key drivers for methane gas trucks
• Availability: Methane gas is the most accessible fuel as an alternative to diesel. Increased focus on biogas production
• Cost savings: Methane gas is currently a relatively cheap fuel in many markets
• Environmental regulations: Affects purchasing decisions, particularly in municipal areas

Methane gas + diesel – technical solution
• A standard Euro 5 diesel engine with 45% energy efficiency
• Over 50% greater operational range compared to a spark ignited engine
• 50-80% of the diesel can be substituted by methane gas
• Can run on only diesel if out of gas

Methane gas + diesel – how it works
• A small amount of diesel is injected and ignited by the compression
• This in turn ignites the methane gas/air mixture
• No need for a spark plug. Allows Volvo to make full use of the efficient diesel technology
• Result: power and driveability identical to that of a conventional diesel truck

Methane gas storage: CNG vs LNG
CNG – compressed methane gas
• Suitable for shorter distances/city traffic
• Benefits from exitingdistribution network

Methane gas storage: CNG vs LNG
LNG – liquefied methane gas • Enables up to 50% longer
driving range • Opens up for new applications• Requires new distribution
network• Truck specific filling station
for LNG

Opportunities for climate neutral biogas
Natural gas: • The most accessible fuel
alternative to diesel, with reserves that will last longer than crude oil
Biogas: • Climate neutral biogas
production is gaining momentum in many countries

Opportunities for climate neutral biogas
Strategy: • Establish the technology with
natural gas. Gradual shift towards biogas when possible

CO2-reduction potential: methane + diesel
• Possible greenhouse gas reduction of up to 80 % when using biogas and biodiesel
• Today 5-7 % biodiesel is mixed with fossil diesel
• The mix could be increased depending on development in technology and accessibility Ny bild här

Field tests in commercial traffic 2010
• Sweden and the UK chosen
– FL/FE trucks in Linköping one part of the field tests
• Trucks to run on methane gas and biodiesel/fossil diesel
• Different types of engines and configurations
• Possible small scale market introduction already in 2011
• Critical: customer demand and gas distribution network
