In the future, ammonia could play a decisive role in the transition from fossil fuels to climate-friendly alternatives — as long as it is produced from green hydrogen, for example, using renewable energy sources. Ammonia is easy to store and transport. Researchers at the Fraunhofer Institute for Microengineering and Microsystems IMM are developing ammonia-based systems for a mobile, decentralized energy supply in the infrastructure, transportation and industry sectors. The various research projects will be presented for the first time at the Hannover Messe Preview on February 15, 2023.
