Hydrogen can be created by decomposing water. Electrolysis which is a method of passing electricity from the water and obtaining the products as hydrogen and oxygen is done by decomposition of water. The water molecule is broken down into its constituents.

If the activation energy is reduced, hydrogen can be produced with a renewable energy source. This renewable energy source is Solar energy.

Solar energy from the sun can be used to lower the energy of activation during the decomposition of water. Solar energy is a renewable energy source as it comes from the sun and is replenish-able unlike fuels which cannot be replenished. The solar energy can be collected and utilized for production of hydrogen.
