The aim of this project is to design and develop a
polygeneration plant prototype based on solar power and solid oxide cells. The
plant basically may consist in a group of dish-Stirling units producing power
from solar radiation supported by a storage system consisting of reversible
solid oxide fuel cells (RSOFC). When the radiation is high, a share of the
power produced by the dish-Stirling units is used in the RSOFC to produce
hydrogen (electrolysis mode). On the other hand, when the radiation is low, the
produced hydrogen will be fed back into the RSOFC to produce additional
electricity (fuel cell mode). For the electrolysis model, it is necessary to
feed the RSOFC with steam which is generated by installing a parabolic solar
through collector (PTSC). Furthermore, the proposed system takes the advantage
of generating heat in a storage cycle, and thereby uses it for sea-water
desalination by a set of direct contact distillation membranes. Some important
points of such renewable system can be mentioned as:
Thanks to the storage system, a high degree of
flexibility in power production can be achieved which is advantageous for
balancing the power network.
The system does not consume any external fuel and
therefore it is self-sufficient.
The combination of electricity and fresh water
production from solar radiation suit perfectly
Different plant design shall be proposed and analyzed.
