Transcript of Alternative Fuels

Hungarian oil situation Biodiesel
Produced from vegetable oils or fat through chemical process

Most common sources:

sunflower A promising source: algae Reducing Co2 emission by 75%, but increasing No2 by 10% contains 3 times the amount of energy it takes to produce it Facts Any diesel motor in any percent It is safer than petroleum diesel Poor cold weather performance Cant supply enough biodiesel to replace petroleum diesel Benefits & Considerations Workable technology:
in 2012 worldwide production
was over 21 billion liter
(135 million barrel) Local emission remains Land usage: fuel of food? 8% less energy per gallon than petroleum diesel Nearly same price as petroleum diesel Hydrogen Not occur naturally on Earth Hydrogen is an energy carrier,
like electricity, not an energy resource Several ways to produce:

Natural Gas Reforming


Renewable Electrolysis Two ways to use:

Fuel to internal combustion engines

Fuel cell Benefits & Considerations zero emission vehicles

fuel cells are highly efficient

can be produced with low- or zero-emission sources, such as solar, wind, and nuclear energy

highest energy content by weight of any fuel
(1kg hydrogen = 3 litres of gasoline) Benefits low volumetric energy density

fuel cell durability ( ~120.000km )

low refueling speed

the price of hydrogen now moderate high
(equivalent to 600-800Ft/l fuel)

can be dangerous if leaking Drawbacks Hydrogen now Honda FCX Clarity Mercedes buses in Perth, Australia Audi, BMW, Daimler, Fiat,
Ford, Honda, Mazda, Mitsubishi, Peugeot, Toyota, Volkswagen Thank you for your attention! Sources Problems Increasing Price Do you remember how much one liter gasoline cost 10 years ago? Air pollution Biogas produced by the breakdown of organic matter in the absence of oxygen:

landfills, livestock operations Biogas comprises primarily:
methane (CH4)
carbon dioxide (CO2)
hydrogen sulphide (H2S) Refining need Can used in any CNG fueled vehicles Developing technology:
Switzerland Local emission, but reduces methane emission Cheap Biogas Ethanol Made from corn and other plant materials, biomass Mixed with petroleum diesel (E10, E85) Not a new concept E100 contains 34% less energy Production amount rises rapidly

Over 85 billion liters (500 million barrel) Flexible fuel vehicles Largest producers:

EU Cars, using gasoline are making air pollution, because toxic gases are released from exhausts. Locale emission Food versus fuel problem New job opportunities Electricity Electricity is a carrier not source Non-renewable Coal
Natural gas
Nuclear Two way to produce Renewable Solar
Geothermal Hungary has some oil reserves in the south-east of the country

It only gives 13% of total oil supply

So Hungary relies heavily on imports

Approximately 87% of crude oil supply is imported

Our main oil supplier is Russia

The oil comes from here via Dhruzba pipeline system Benefits and Considerations Low range
Expensive vehicles
Long recharge time
Battery degradation
Heating 228 Ft/liter 428 Ft/liter No local emission
Zero emission
Cost effective (30%) For these reasons, we must seek for alternative fuels instead of oil

In this presentation we are going to introduce some of these Oil Gasoline/Petrol Cars Public transport Commute Prices MOL Hybrid electric vehicle battery + internal combustion engine 2012 Chevrolet Volt no range problems uses fossil fuels medium-term solution 1. Introduction

2. Hungarian oil situation

3. Problems

4. Alternative ways http://epp.eurostat.ec.europa.eu

Smog alerts Kakas Gábor
Kolláth Attila Facts Carbon monoxide (CO)

Sulfur dioxide (SO2)

Hazardous air pollutants (toxics) Oil is not a renewable source

The earth will run out of oil sources in the next 50 years

Exploiting the oil sources will cause serious problems

Oil gives the 40% of electricity generation and 90% of transport resources at the moment. Exploiting of the oil sources
