No, liquid ammonia does not have nearly double the energy density of liquid hydrogen. Liquid ammonia has an energy density of about 11.5 MJ/L, while liquid hydrogen has an energy density of about 8.5 MJ/L. Therefore, liquid ammonia has a higher energy density compared to liquid hydrogen, but it is not nearly double. **
