Renewable hydrogen is created by using electricity to split water into hydrogen and oxygen through a process known as electrolysis. The hydrogen is collected and used, primarily in industry, while oxygen is released as the by-product or captured for use by others. As we use electricity created from renewables, the process is carbon-neutral.

If the electricity is generated from renewable sources such as solar or wind, production of hydrogen in this way emits no greenhouse gasses. This is how we come to all the different shades of

Lower carbon footprint: when hydrogen is produced using renewable energy sources, its carbon footprint is much lower than that of traditional fossil fuels [30].

Energy storage: hydrogen can act as a form of energy storage. It can be produced (via electrolysis) when there is a surplus of electricity, such as during periods of high wind or solar generation. It can then be stored and used later when demand exceeds supply or during periods of low renewable generation. 5.
