CO2 Sequestration through Deep Saline Injection and ...

CCLC system will require a solar collector field of 37 km 2 , this represents a 54% decrease in the
amount of area needed to produce the same amount of electricity.
The following figure, Figure 19, provides an energy balance summary for the system. The
equations and process used to determine the energy balance and subsequently the reflective
surface area required of the heliostats is included as Appendix C.

3.4. LIGHT COLLECTION
The function of the solar collector is to concentrate collected solar light and reflect it onto a
receiver for transmission into the bioreactor and/or to generate electricity from the light. The
light collection system can be described in terms of: the light wavelength that can be used by
each part of the system, the types of collectors and modules for light collection, the orientation of
solar collector dish, and the solar collector’s efficiency. Designing considerations include
optimizing the performance and cost of sunlight trackers, dish concentrators, IR cold mirrors and
optical fibers.
There are several light collector types and they function in different ways and yield different
collection efficiency. Several light collectors were considered for this project and are
summarized hereafter. However, the heliostat/light collection tower was selected for the final
design. It is important to consider that the collected light needs to be treated so that the visible
light is transmitted into the PBR and the Infrared (IR) is transferred to the solar-electric
