For the future hydrogen supply, large quantities must be transported over long distances. However, the cost of transporting the energy carrier and chemical raw material is comparatively high.
Alternatives to the liquid transport of H2 are the use of carriers such as ammonia or methanol. Ammonia is combustible and can be converted directly to electricity in fuel cells. Ammonia burns to nitrogen and water and is therefore climate neutral. Among the alternatives, it currently has the highest degree of technological maturity for transport and storage. Dr.-Ing. Gunther Kolb from the Fraunhofer Institute for Microtechnology and Microsystems IMM explains how ammonia, but also methanol, can be used to transport hydrogen, and both are also used in fuel cells.
