Green Hydrogen
Topic outline

Chapter III - The Transportation and Storage of Hydrogen by Fabian Carels, HOOU (CC BY-SA) Whether oil tankers and gas pipelines or batteries, power lines and pumped storage power plants... Storage and transport are central elements of a stable, reliable energy supply, regardless of the form (solid, liquid, gas, electricity) of the energy carrier.In this chapter, you will get to know why storage and transport play a particularly important role when it comes to integrating green hydrogen into the energy system. You will learn how and in what forms hydrogen can be stored and transported, what challenges arise and how they can be overcome. You will also see, using the example of some selected projects in northern Germany, where the development of a storage and transport infrastructure for hydrogen is already underway.
The contents of this chapter are supplemented by lectures of experts from practice and science:- Prof. Dr. Michael Fröba; Institute of Inorganic and Applied Chemistry, University of Hamburg - Hydrogen storage options – Possibilities and their assessment
- Dr. Julian Jepsen; Institute of Materials Research, Helmholtz-Center Geesthacht - Hydrogen storage in metal hydrides
- Lucas Sens; Institute of Environmental Technology and Energy Economics, Hamburg University of Technology - Hydrogen supply chains – Options and their assessment

The storage and transport of energy are generally required to compensate differences in time and space between production and demand. In principle, this is true for all energy carriers, but storage and transport are of special importance in the context of green hydrogen. There are two main reasons for this, which are briefly explained in the following.

ViewThis chapter discusses the options for storing hydrogen, categorized as physical and material-based methods. The graph illustrates the volumetric and gravimetric energy densities achieved by different storage methods. Compressed gaseous hydrogen and liquid hydrogen are explored, along with underground storage facilities. Liquid Organic Hydrogen Carriers (LOHCs) and metal hydrides are also mentioned as potential storage options.
