Nitrogen-Based Fuels: A Power-to-Fuel-to-Power Analysis

What are the fuels of the future? Seven representative carbon‐ and nitrogen‐based fuels are evaluated on an energy basis in a power‐to‐fuel‐to‐power analysis as possible future chemical hydrogen‐storage media. It is intriguing to consider that a nitrogen economy, where hydrogen obtained from water splitting is chemically stored on abundant nitrogen in the form of a nontoxic and safe nitrogen‐based alternative fuel, is energetically feasible.
