Modern nuclear reactors are dispatchable and can scale to the demand to some extent. Maybe this should be more clearly reflected instead of just assuming a constant baseload?

  Based on the French and the German experiences, nuclear power has the technical capabilities to engage in load following. While more precise results would depend on the specific reactor technologies employed, the results below were reported for currently operating reactors in France and Germany

  It is easy to see that the reactor is capable of large power variations, both upwards and downwards. It can therefore easily adjust to the demand curve (we speak of load monitoring). In practice, a nuclear power station can now vary its power by 30 MW per minute, which is equivalent to what a regular gas-fired plant can do (a high-performance gas-fired plant can go up to 50 MW per minute).

Awesome tool!

I enjoyed playing around with this, and discovering a mix that would get to zero carbon emissions, but it relies heavily on nuclear while having a substantial excess of wind:

It'd be interesting to be able to factor in grid-scale energy storage systems, which might capture some of the excess wind or solar power and use that to fill in gaps; there are a number of different potential solutions ranging from pumped hydro to batteries.

Very nice website, it's well made. I have seen that you are totally neglecting hydropower (dam, conduit, etc) in the main graph, is there a particular reason for that?

Indeed this kind of technology can be use to store efficiently the exceeding energy produce by renewable energy and thus smooth the curve.

Great model and approach. Do the fixed storage costs represent the first cost of the equipment? It's interesting that Hydrogen's fixed cost per the storage_costs.csv is factors of magnitude less then electro-chemical.
