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

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

In summary – methane gas + diesel

• Large methane gas reserves

• Increased biogas production

• High fuel efficiency

• Over 50% greater operational range compared to a spark ignited engine

• Suitable for long-haul applications (LNG)

• 80% greenhouse gases reduction potential
