Transcript Slide 1
BTRE Transport Colloquium
Canberra 13-14 June 2007
Cars, Trucks, Planes:
What will drive them in the future?
Headlines: (1)
• Biggest increase in Australia’s
emissions since 1990 is private
transport
– Increased 29% since 1990
Headlines: (2)
• Public transport in crisis
– “Transport congestion choking Melbourne” -- The Age
– “Fuel price drives commuters onto buses and trains”
-- SMH
• What do these problems have in common?

Greenhouse gas emissions
Australian transport
GHG must not be confused with Air Quality!
Air quality is an issue in urban areas
(particulate carbon, mostly from diesel)
GHG emissions are a national/global issue
Methane (CH4) and nitrous oxide (N2O) also need to be considered.
Change in emissions profile
Why the increase in GHG for cars?
2NO
2NO2
N2 + O2
N2 + 2O2
N2O
Nitrous oxide (N2O)
is 310 times as potent
as carbon dioxide
And there’s a second reason!
Engines have improved in
fuel efficiency 20% over
the past 20years, However
this has been offset by
growth in vehicle size

Biofuels from current agriculture
Ethanol
If we used all the crops (sugar, molasses, wheat, coarse
grain) suitable for making ethanol and converted them to
fuel it would only replace 75% of our petrol.
(If we stopped exporting grain we could replace 25% of our petrol)
Biodiesel
If we used all the crops (canola, cottonseed and others)
suitable for making diesel and converted them to fuel we
could replace only 10% of our diesel usage.
Conclusions:
Ethanol could support E10 for most of Australia
Urgent research is needed into next-generation biofuel technologies.
Side effects of biofuels

• Automobiles are becoming
increasingly electrified
• There is a strong demand for more
energy storage on board the vehicle.
• Much research into high-tech batteries
In partnership with Holden the
ECOmmodore, a parallel
hybrid vehicle.
With aXcess Australia, a
series hybrid vehicle.

The Future?
•
Expect more pressure to reduce emissions
•
Simplest ways to reduce emissions: –
–
–
–
Reduce travel (particularly in cities)
Reduce vehicle size where possible
Improve traffic flows
improve fuel economy of vehicles
•
Expect more pressure to reduce emissions
•
Expect more technological improvements in
engines.
•
Hybrids save fuel (and emissions)
– but mostly in the city
(short journeys and stop-start driving)
The easiest ways to reduce emissions are to reduce travel,
reduce vehicle size, then reduce congestion.
