Abstract
A novel plant based on reversible solid oxide cell, absorption chiller, water distillation and wind turbines is designed and analysed. The main goal is produce hydrogen from excess electricity generated by the wind turbines. The off-heat from the plant is recovered to generate heat, cool or freshwater. Thus, different plant designs are presented depending on the demand and location. Further, solar energy is used to heat up water and regulate the heat production for the district heating. It is shown that the plant is able to produce hydrogen at about 2000 kg/day and the plant hydrogen production efficiency reaches to about 44%. Total plant efficiency (energy efficiency) will be close to 52% when heat, cool and freshwater are accounted. Neglecting the heat input through solar energy to the system, then hydrogen production efficiency will be about 75% and the total plant efficiency will be about 90%. In addition, plant performance versus wind velocity is also analysed in terms of heating, cooling and freshwater generation.
