Overview
Fraunhofer IMM
In the Division ENERGY we deal with current and future issues concerning the mobile and decentralized provision and storage of electrical energy with a stronger focus on sustainable energy sources. Our activities are directly related to the Fraunhofer Strategic Research Field HYDROGEN TECHNOLOGIES, promote the decarbonization of industry and increasingly aim at CO2 neutrality in processes.

How to process ammonia as hydrogen carrier for energy generation
Hydrogen is a crucial energy carrier for the transition of the global industry, transport and energy sectors from fossil fuels to carbon-free energy sources. However, hydrogen has a very low volumetric energy density which makes its transport and storage challenging. Hydrogen carriers such as ammonia can mitigate this problem. Ammonia is carbon free, contains 17.6% hydrogen, has a much higher energy density compared to hydrogen and can be liquified at a moderate pressure of about 9 bar at 20.0°C.
Furthermore, ammonia is the second most widely produced chemical and its transport in large quantities by land and sea is daily practice, for this reason the technology and safety procedures are well established. At site of demand the ammonia can be cracked to release hydrogen and nitrogen. While fuel cell applications require purification of the hydrogen and promise highest system efficiency, ammonia/hydrogen mixtures produced by partial cracking of ammonia can also directly be fed into internal combustion engines and turbines.
Hence, ammonia cracking will foreseeably become an important process for hydrogen generation for decentralized and mobile applications. At Fraunhofer IMM we develop ammonia cracking systems applying proprietary catalyst and reactor technology. The reactors are designed as microstructured heat exchanger reactors with catalyst coating and enable the use of off-gasses from the hydrogen purification for heating via catalytic combustion. Additionally, the reactors offer better heat management and catalyst utilization compared to conventional reactors and are therefore much more compact.
In our webinar, we will give you an insight into our expertise in the ammonia cracking technology. We show you possibilities how you can benefit from our experience as a facility for applied research and development with us as a partner.
The presentations will be held in English.
