Fusion requires enormous (10 million Kelvin) temperatures to get it going so there is the difficulty of heating the hydrogen fuel to this temperature and then containing it.

Hi Leila,

Nuclear fusion requires a very high temperature (100 million kelvin) and very high pressure, which we can't currently achieve on Earth.

Think you can help?
