Transport

• Accounts for around a third of all final energy consumption

• Responsible for over a fifth of greenhouse gas emissions

• Transport volumes are growing annually


Ways of Transportation

• Land– Consumes on average 85% of the total

energy used by transport

• Sea– about 7% of energy for transportation is

used for maritime transport

• Air– Aviation uses about 8% of the energy

needed for transport issues


Energy Demand by Modes of Transport


Impacts of Transport


European Greenhouse Gas Emissions


The Greenhouse Effect

• The greenhouse effect is the rise in temperature that the Earth experiences because certain gases in the atmosphere (water vapour, carbon dioxide (CO2), nitrous oxide, and methane, for example) trap energy from the sun by absorbing infrared radiation. Without these gases, heat would escape back into space and Earth’s average temperature would be about 30°C colder. Because of how they warm our world, these gases are referred to as greenhouse gases.


Road Safety


Particulates in the Air (PM10)

• Transport not only produces gaseous pollutants but also small particles that can cause various diseases. These particles are mostly produced in the residential sector and by transport (especially from diesel engines).


Particulates in the Air (PM10)

• Dusts with a particle size lower than 10 micrometers are considered as fine particles or particulate matter (PM10). Particles with diameters below 10 micrometer are considered as respirable, particulate matter smaller than 2,5 micrometer can penetrate into the gas exchange regions of the respiratory tract and also affect other organs besides the lung itself.


PM10 Emissions in Europe


Energy Efficiency in Transport - Approaches

• Alternative Fuels

• Alternative Vehicles (designs, engines, etc.)

• Transport management systems

• Sustainable driving


Fuels

• Traditionally, the word fuel denoted any substance, or mix of substances, that after a burning chemical reaction, produces a large amount of heat.

• Alternative fuels are any substances or sources of energy other than conventional fuels (gasoline and diesel), that can be used for transport. They are also called “non–conventional fuels”.


Oil based fuels

• Gasoline- a volatile flammable liquid hydrocarbon mixture used as a fuel especially for internal combustion engines and usually blended from several products of natural gas and petroleum.

• Diesel - produced from petroleum and is a hydrocarbon mixture, obtained in the fractional distillation of crude oil between 200° C and 350° C at atmospheric pressure.


Gasoline Composition

•The octane number (ON) is the main criterion for determining the antiknock quality of gasoline. It is determined through the comparison of gasoline with standard compounds, with a known octane number.


Alternative Fuels


Fuels from Natural Gas

• Compressed Natural Gas (CNG)

• Liquefied Natural Gas (LNG)


Liquefied Petroleum Gas (LPG)

• Liquefied petroleum gas or LPG is a colourless hydrocarbon gaseous mixture, mainly containing propane and butane (i.e. 60% propane and 40 % butane or even 100% propane, or 100% butane).


Hydrogen Fuel Cell

• The Hydrogen fuel cell uses Hydrogen as fuel and Oxygen as oxidant.


Biofuels

• A bio fuel is a gaseous, liquid, or solid substance of biological origin that is used as a fuel.


Bioethanol in EU


Human Power!


Example - Hybrid car

• Mixture of an electrical and conventional drive train

• Designed to obtain different objectives like improved fuel economy, increased power, etc.


How does it work?

• The car transforms energy from braking into electric energy

• Energy is stored in batteries• Batteries do not need external power supply or

recharging• Electric motor assists the engine in accelerating,

passing or hill climbing• Engine is shut off automatically when the car

stops and so prevents waste of energy from idling


Example - Hybrid car


Battery Powered Transport

• Electric vehicle batteries (EVBs) are rechargeable batteries used in all-electric vehicles (EVs) or in plug-in Hybrid-Electric Vehicles (PHEVs). The amount of electrical energy stored in any battery is measured in ampere hours, while energy is usually measured in watt hours.


Battery Charging

• Batteries in electric cars must be periodically recharged. The most common way of charging these batteries is to use the electricity grid (at home or in on-road recharging points), that delivers power generated from a variety of energy resources (including coal, nuclear, etc.).


Transport Modes- Space Occupancy


Example – Sustainable driving

• Requires a general change of behaviour

• Can easily be carried out by everyone

• Can improve mileage by 15-20%

• Reduces Greenhouse Gas emissions


Ecodriving – Driving Tips

• Accelerate and brake smoothly

• Slow down and watch your speed

• Let aggressive drivers pass by

• Plan your trips

• Coast down hills and slight grades

• Etc.
