What is then a good market design for a decarbonized grid consisting of mostly ~zero marginal cost producers like wind, solar, hydro and nuclear? Seems dispatching on marginal cost doesn't make sense in such a world?

Both the ERCOT & SPP markets have had renewables as a percentage of load as greater than 50%, but that is generally during the night with low load and high wind. I'm not sure what markets will look like in 20 years, but they could be very different if we have 100% renewables and a high amount of grid level storage.
