How is electricity geneerated using ethanol?

Answer 1

Well ethanol is burned according to the equation:

C2H5OH(g) + 3 O2(g) → 2 CO2(g) + 3 H2O(l); (ΔHr = −1409 kJ/mol)

where delta h (-1409 kJ/mol) amount of energy given off per one mole of ethanol which is combusted.

There are two ways to harness the energy given off:

Internal combustion engine -like a car the explosion caused by ethanol and oxygen is used to move a cylinder.

But for electricity the ethanol will be burned and the heat used to heat water until it turns to steam. The pressure generated by the steam is used to turn a turbine which rotates magnets around a coil of wire which generates electricity!

hope it helps!

Answer 2

Ethanol can be used as a fuel in power plants to generate electricity. The ethanol is burned to create heat, which is then used to produce steam that drives turbines connected to generators. These generators convert mechanical energy into electrical energy, which is then distributed through power grids.
