Integration of Hydrogen Energy Technologies in Autonomous Power Systems 

However, hydrogen is not an energy source, but a carrier and consequently it will be as clean as the method employed for its production. Moreover, today its transport and storage is expensive and difficult and constitute the main drawbacks 

Hydrogen (H2) is almost everywhere, but unfortunately it is hard to find it on earth as a separate element. Instead, it is primarily chemically bonded with oxygen in water, with carbon in a range of hydrocarbon fuels and in plants, animals, and other forms of life. Hydrogen bound in water and organic forms accounts for more than 70% of the Earth s surface (Dunn, 2002). Once it is extracted, this colourless, odourless, and tasteless element becomes a useful feedstock to a variety of industrial activities — and a potential fuel sufficient to energise all aspects of society, from homes to electric utilities to business and industry to transportation. 

Hydrogen is a high-quality secondary energy carrier and not an energy source. Therefore, it has to be generated from another resource, a fact that poses challenges and complexities, but at the same time offers an opportunity to utilise a diversified mix of domestic resources, reduce dependence on oil imports, reduce gas 

Depending on the scale of application, hydrogen production processes are characterised as forecourt (smaller distributed facilities located onsite at refueling stations, sized at 100 to 1500 kg H2 per day) and central (large plants, sized at
