Abstract
Electric power generation from thermoelectric power plants is associated with
a negative impact on water availability, referenced as the water‐energy nexus,
which is aggravated by climate change. In the present study, the effect of four
different hybrid cooling system configurations on water usage and power penalty
of a natural gas combined cycle has been investigated. The hybrid cooling
system with a parallel connected indirect dry cooling system and wet cooling
system is the most conventional studied hybrid cooling system in the literature,
while the other studied hybrid configurations in the present study are novel
regarding their effect on water requirement and power penalty. Simulations
were conducted using the COCO 3.3 software and have been validated using
data sets from a reference natural gas combined cycle plant, both with and
without carbon capture unit, which is available in the literature. Four hybrid
cooling system configurations were explored to evaluate their water requirements
and power penalty. Other conventional cooling systems such as closed
cooling, once‐through, and direct and indirect dry cooling methods were simulated
with and without post-combustion carbon capture (PCCC) integration
for comparison. It was found that the hybrid configuration, including indirect
air‐cooled condenser and natural draft wet cooling tower, has the best performance
as compared to the other conventional and hybrid cooling systems,amounting to 2.038 (gal/min)/MWnet, 1.573 (gal/min)/MWnet, and 12.29 MW
for water withdrawal, consumption, and energy penalty, respectively, for the
case of a unit without PCCC unit and 3.9 (gal/min)/MWnet, 2.928 (gal/min)/
MWnet, and 15.177 MW for water withdrawal, consumption, and energy
penalty, respectively, for a unit with carbon capture unit. It was confirmed that
the PCCC integration approximately doubles the water withdrawal and consumption
for all cooling systems. In addition, the indirect air‐cooled condenser
and wet cooling tower is still the best performing cooling system with PCCC
integration.
