Hydrogen Energy, Hydrogen Efficacy, Direct Contact Seawater Evaporation.
Possible usage of hydrogen over a hydrocarbon (propane) in direct contact evaporation of seawater is evaluated. Selection of propane was made for two reasons: First, it is a representative fuel of hydrocarbon family and second it is often used because of its clean burning characteristics. For the same heat input requirements, an equal amount of seawater can be evaporated with 38% less hydrogen fuel on a mass basis. On the other hand, hydrogen costs an order of magnitude more compared to propane. Although environmentally advantageous, the use of hydrogen fuel will probably be dalyed until its production costs are competitive.
