Hydrogen Distribution
Revolutionary catalysts
for the energy transition

Green hydrogen from renewable energy sources, such as wind and hydro power, can be an abundant, versatile, and clean energy source. Consequently, there’s great interest in an energy transition away from fossil fuels toward a hydrogen economy, with the goal of decarbonizing transport and industry. There’s just one problem with hydrogen: its high volatility and very low density make it difficult and expensive to transport over long distances.

The most economically viable solution is to chemically convert hydrogen into a safer form for transportation, then reconvert it at point of use. There are currently two effective ways to »carry« hydrogen: via LOHCs, or ammonia. Clariant is proud to be one of the frontrunners in developing highly specialized catalysts for both pathways.

Hydrogen Transport via Green Ammonia

Process

Transporting hydrogen through chemical conversion to ammonia is gaining considerable attention as it is expected to be the most cost competitive solution at the very large scales required. In this method, hydrogen is first converted to ammonia (NH₃) for storage and transportation, then at the point of use, ammonia is reconverted to hydrogen via cracking. As one of the leading catalyst providers in the ammonia-related new hydrogen economy, Clariant offers highly innovative catalysts for ammonia synthesis and its cracking.

Collaborations

Clariant’s efforts and progress in hydrogen transport via green ammonia cracking have grown substantially in recent years. We work closely with renowned technology partners, such as KBR and Casale, to jointly develop optimal solutions for each specific project. One such collaboration lead to the creation of the ground-breaking AmoMax® Casale catalyst tailor-made for Casale ammonia convertors.

We also participate in several major multilateral projects, such as Germany’s prestigious TransHyDE project AmmoRef, which is tasked to advance technologies for ammonia reforming to support the national and global hydrogen revolution. Besides developing next-generation ammonia cracking catalysts for the project, Clariant will also provide its benchmark ammonia synthesis catalyst AmoMax® 10 Plus.

Hydrogen Transport via LOHCs

Process

Liquid organic hydrogen carriers (LOHCs) are an ingenious means of transporting hydrogen by chemically binding the molecules. Developed by Hydrogenious Technologies, the method involves hydrogenation of the liquid organic hydrocarbon benzyltoluene using Clariant’s EleMax® H catalyst to “store” hydrogen. At point of use, dehydrogenation with EleMax® D »releases« hydrogen on demand. The tailor-made catalysts offer exceptional activity and selectivity for loading and unbinding hydrogen in order to optimize the life cycle and efficiency of LOHCs.
