# Geothermal Combined Heat and Power Problem using a Thermal Drawdown Reservoir Model and BICYCLE Economic Model and
# Solid Sorbent Direct Air Capture powered by geothermal
# Based on Example 3 description: This example problem considers an EGS reservoir at 3.1km depth.
# The heat is used in a combined heat and power topping cycle model with double flash as
# topping cycle and electricity considered as the main product.
# But only lists those parameters that are different than their default values
