Abstract [en]

The following report is a comparison study of the alternative for the future automobile

sector, where the fuels in focus are bioethanol, bio gas, electrical vehicles

and hydrogen gas. Through this comparison one or multiple of fuels will be decided

to be the better solution for a future without greenhouse emissions. Since

transportation one of the major areas of polluting an instant change has to be

made sooner than later. The main purpose is to give people an understanding

of the fuels and then give simple data to interpret. By comparing the vehicle

performances and society integration for each fuel there will be many di erent

perspective to analyze and take into consideration.

The structure of the comparison is divided into two major sections, one that is

based on how the fuels interact with the vehicle. Categories are created within

the sections, where Content of Energy tells the potential of energy extraction

and Fuel Eciency shows consumption of energy and operational cost. To this

category does the WTW expression belong as well for specication of the energy

losses. A nal performance category in acceleration gives an indication of

how attractive the fuel might be. Following the performance section, the society

integration focuses more on the big picture, such as investment cost and

convenience.

First of all regarding the performance of the fuel, after summarizing the categories

Fuel Cell H2 was the number one choice. As the runner-up was the

electrical vehicle and worst case was bio gas. Secondly, the society integration

based on cost and convenience, the electric vehicle had an estimated investment

cost of 41,300 MSEK to supply Sweden. To combine these two major areas

the conclusion leads to an announcement of EV:s as the best option out of the

studied. As a consequence of the simplicity to use electric power without any

direct emissions from the vehicle itself, the EV:s are the most convenient vehicle

eet to establish.

This would be with conditions that are based on today's advances in technology

and knowledge about possible developments over time. The conclusion

is open for the unknown and eventually correct itself to upcoming fuels. But as

for now, the important part of this discussion is to make a move away from the

gasoline-dependent society and give the future generations better conditions.

Abstract [sv]

Foljande rapport ar en jamforelsestudie av alternativa branslen for framtidens

fordonsindustri, dar de inblandade branslena ar bioetanol, biogas, eldrift och

vatgas. Med denna jamforelse ska ett eller era branslen beslutas vara det mer

lovande till en framtid fritt fran vaxthusgaser. Eftersom transportsektorn har

en stor bidragande faktor till global fororening behovs en forandring goras inom

en snar framtid. Huvudstyftet med denna rapport ar att ge folk en generell

overblick av vilka branslen som nns tillgangliga och hur de star sig mot varandra.

Mer i detalj kommer bilars prestanda och samhallsintegrering att jamforas

for varje bransle, for att sedan analyseras.

Som namnt ovan kommer jamforelsen vara indelad i tva sektioner, en dar prestandan

mats och en hur enklet en etablering av branslet i samhallet skulle

var. For prestanda kommer delarna att vara energiinnehallet av branslet och

bransleforbrukning for bilen, dar tillhorande kategorin WTW anvands for mer

specikation av energiforluster. Till sist en kategori som jamfors de olika branslenas

acceleration. Pa andra sidan jamforelsen kommer samhallsintegreringen

bestammas av etableringskostnad och omstallningsmojlighet.

Efter att ha gatt igenom alla kategorier tillhorande prestanda ar det branslecellsbil

med vatgas som presterar bast. Nast bast blir den elektiska bilen och samst

blir biogasbranslet. Gallande fallet for kostnad och smidighet av samhallsetablering

blir det ett klart overtag for eldrivna bilar. En total kostnad pa 41,300

MSK skulle kravas for fullsklaig forseelse i Sverige. For att sedan sammanstalla

det slutgiltiga beslutet fran jamforelsen eldrift av fordonsottan skulle vara det

basta alternativet.

Det slutgiltiga beslutet baseras pa den tills idag kanda teklonogin och utvecklingen

utav denna. Sjalvklart star slutsatsen oppen for uppkommande branslen

som inte i dagslaget har etablerats eller visat likvardig potential. Huvudmalet

med hela diskussionen ar att ta nagra steg ifran det besninsamhalle som vi lever

i idag och pa sa vis ge framtida generationer battre forutsattningar.
