This thesis work aims to study the possibility of energy production on
Martian soil and, in particular, to establish what might be an optimal
configuration for an energy system. This goal has been contextualized in the
will to feed a scientific base, based the concept of “Mars Direct” (Robert
Zubrin, 1990). This habitat has been recreated in its thermal features, in
order to perform an analysis of the heat loss over a Martian year (1,88
terrestrial years). As part of this analysis, two possible scenarios have been
studied: clear sky with medium solar radiation (“sun season”) and sand storm
season (“storm season”). Subsequently, a basic life support system have been
simulated thanks to Aspen PLUS. Using the results of the thermal analysis, it
has been possible to obtain a thermal and electrical demand profile for the
Hab. After identifying every possible energy source (solar, wind, nuclear, fuel
cells, rtg), a calculation on Excel has been set with the purpose of finding
one of the configurations with the lowest possible mass and pave the way for a
further, more rigorous, optimization. It is indeed clear that shipping 1
kilogram to Mars has a cost of hundreds of thousand of dollars.
