The chemical energy was stored in the fossil fuel millions of years ago when the Sun's energy was used in photosynthesis to separate carbon and oxygen atoms from atmospheric carbon dioxide. The carbon was used by the plants to form tissues while the oxygen was released into the air.
It's this energy that is released by the formation of carbon-oxygen atomic bonds as carbon dioxide is generated when the fuel is burned.
Fossil fuels represent chemical energy, a form of potential energy. This energy was stored in the hydrocarbon molecules and can be released by oxidation (burning).

Potential
The heat is produced by the formation of chemical bonds between carbon and oxygen, and between hydrogen and oxygen. So CO2 and water are the necessary products when fossil fuel is burned, without which there would be no heat.
Potential Energy
When fossil fuels are burned they turn into mercury which released into the atmosphere
A fossil fuel contains chemical energy. When it is burned this is turned into thermal or heat energy. This then may be converted into some other form including kinetic energy.
