Question

What will power the cars of tomorrow (in about 10 years, ~2030)? Choose and describe one energy source. 1 point Explain the reasons for your choice and identify the advantages and disadvantages of "tomorrow's" cars power supply (not just in the vehicle but at the fuel's / power supply's source). 5 points

Answer 1

In order to reduce pollution and for gaining energy independance ,every country should produce renewable energy.In my opinion hydrogen will be a good alternative.Today hydrogen is used as a propellant for satellite missions by NASA and other space agencies.It's main feature is it can be compressed like LPG's and use it normally on cars .we can use hydrogen fuel cell in cars.The two chemicals that react together in a hydrogen fuel cell are hydrogen and atmospheric oxygen.Also it only produce water as exhaust and can be refueled faster than electric cars.

Advantages

• Hydrogen has high energy richness compared to petrol or battery powered electric cars.
• It does not emit toxic gases to the atmosphere.
• Reduce noise pollution.
• Produces only water as exhaust.
• Refuels faster than electric cars.
• Low maintenance.
• Reduce carbon footprint and positively affects the economy.

Disadvantages

• Hydrogen is very expensive to produce since hydrogen is not seen in its pure form.
• Difficult to transport and store.
• Incompatible with current infrastructure.
• Need of hydrogen filling stations since it is more expensive.
• Difficult to compress a significant amount of hydrkgen.
