Water under heat and pressure can cause a multitude of reactions due to its universal solvent properties. The free hydrogen and oxygen created while under this state can alter the physical properties of other materials. Thus a endothermic reaction, causes a reformation of H2O into things like syngas which is produced and utilized by industry, by the steam reformation of oils. Biodiesel to methane is also one of these reactions. In the reversible component of this type of reaction Mercedes and BMW have the blue-tec system which combines NH4 to make H2O, nitrogen to reduce pollution from turbo diesel's.
