- Getting energy from hydrogen
- Reaction between H and O is exothermic - energy released
- Hydrogen gas can be burnt to power vehicles
- H gas can be burnt in oxygen as a fuel in the combustion engines of vehicles
- Pros: H+O = water - so it is clean
- Cons: H hard to store safely - explosive, need energy from another source to make it - still be using up non renewable fossil fuels
- Fuel Cells
- An electrical cell that is supplied with a fuel and oxygen and uses energy from the reaction between them to generate electricity
- Does not run down and does not need recharging
- Will produce energy in the form of electricity and heat as long as fuel is supplied
- Only waste product is water
- Do not produce pollution - major advantage in cities
- Can help countries become less dependent on crude oil
- Not dependence on fossil fuels
- H fuel often made from hydrocarbons from fossil fuels or by electrolysis of water, uses electricity - has to be generated somehow
