This is the fuel cell powerplant for my upcoming game, resembling the tech tier 1 level.
While Earth is highly dependend on thorium reactors for their energy output, the detection of underground ice on Mars in abundance led to the decision to use the more cheaper, but less efficient energy production with fuel cells on the distant colonies. The fuel cell powerplant is equipped with 3 oversized fuel cells of the newest generation, and also a highpower steam turbine to take advantage of the excessive heat generated by the fuel cells chemical reaction. This combination allows for a large energy output on a reasonable scale of costs and maintainance. The hydrogen and oxygen for the process is being created in the refinery by splitting up the water generated from the underground ice fields.
