While the goal of the project was to create a 100% renewable energy source based on sunlight, another energy source could probably be used.

This is a heat engine. Your options for renewable heat are mostly geothermal or solar.

The question is... if we connected the hydrogen to a fuel cell, is it more efficient than a steam generator?

I am skeptical. Large steam generators are very, very good.
