An Overview of the Pilot Hydrogen Projects

The continuous growth of greenhouse gas emissions has led to the adoption of new policies and decisions to deal with climate change. Changing the current energy systems to sustainable ones with minimal pollution is achieved by using various techniques such as energy efficiency and the combination of different energy systems and sectors. Hydrogen is a clean and stable energy carrier that releases only water as a byproduct with no carbon dioxide emission and simultaneously converts it into electricity. It can easily be transported from the production site to the utilization/storage centers using pipeline networks or trucks. In this regard, the power-to-hydrogen concept for supply of storage, demand management, and the combination of various elements between different sectors has attracted considerable attention. In this chapter, the developments and prospects of hydrogenated technologies in power systems including their application in power systems for hydrogen production will be reviewed.
