A Green Ammonia Economy

Yoshitsugu Kojima

Ammonia has a high volumetric hydrogen density of 107.3 kg H2 per cubic meter, because it is easily liquefied by compression below 0.86 MPa at 20° C. The vapor pressure of liquefied ammonia is similar to propane. Moreover it has a high gravimetric hydrogen density of 17.8 mass% compared with the solid state hydrogen storage materials. It is noteworthy that ammonia can be synthesized from hydrogen in large scale manufacturing by Haber–Bosch process at 400-600° C and 20-40 MPa. Therefore, liquid ammonia is one of the most promising methods for storing and transporting hydrogen. CO2 free hydrogen (ammonia) will be…

NH3 Fuel — Gaining Momentum

NH3 Fuel — Gaining Momentum

Norm Olson

This paper provides an overview of the impressive characteristics of NH3 as a fuel. NH3 is the closet thing to an ideal fuel due to its production flexibility, competitive cost, infrastructure cost/availability, efficiency, environmental performance, and safety. This year’s presentation will emphasize why NH3 is the best bridge fuel between fossil and renewable fuels and why it is relatively simple to make NH3 safe enough to meet the most stringent existing fuel safety standards.
