C3- Getting energy from Hydrogen
- Hydrogen and oxygen react to produce water.
- This isn't a pollutant.
- This is exothermic as it releases energy.
- You can get energy by reacting these for things
such as a combustion engine or in a fuel cell.
- This isn't a pollutant.
- Hydrogen gas can be burnt in oxygen as a fuel in the combustion engines of vehicles.
- This is very clean
- It needs a special, expensive engine. It is also hard
to store hydrogen safely - it's very explosive.
- This is very clean
- Fuel cells use fuel and oxygen to produce electrical energy.
- A fuel cell is an electrical cell that's supplied with a
fuel and oxygen and uses energy from the
reaction between them to generate electricity.
- Fuel cells don't run down or need recharging
from the mains. It will produce energy in the form
of electricity and heat as long as fuel is supplied.
- A fuel cell is an electrical cell that's supplied with a
fuel and oxygen and uses energy from the
reaction between them to generate electricity.
- Fuel cells are used to replace petrol/diesel engines.
- Don't produce any conventional pollutants (greenhouse gases,
sulphur dioxide). The only by-products are water and heat
- Helps countries become less dependent on crude oil.
- Not likely to mean the end of power stations/fossil
fuels becuase hydrogen takes up more space to
store than petrol,it's very explosive,uses electricity
to make (hydrocarbons) which uses fossil fuels.
- Don't produce any conventional pollutants (greenhouse gases,
sulphur dioxide). The only by-products are water and heat
