A technological roadmap to the ammonia energy economy: Current state and missing technologies

Ammonia is considered a key energy carrier with potential applications for low carbon storage, transportation and power generation. This carbon-free molecule offers several advantages, including high density well-established production distribution infrastructure that have been optimized over century. In this perspective, we analyze the roles of ammonia as an carrier, summarize research areas requiring further development implementation building block in global low-carbon landscape. technologies are reviewed emphasis on current limitations recent advances. Focus placed available synthesis, decomposition into COx-free hydrogen direct use generation transportation.
