That is called chemical energy - assuming conventional fuel. Nuclear fuel has nuclear energy.
It is chemical energy.
Chemical.
Energy is stored in fuels through the chemical bonds that hold the fuel molecules together. When these bonds are broken during combustion, energy is released in the form of heat and light. The type and amount of energy stored in a fuel depend on its chemical composition.
Chemical energy - this includes the energy stored in fuels - is a type of potential energy.
