They do discuss several commonalities in the paper.

If it is to meet the Paris Agreement target, the worldwide average carbon price in 2030 needs to be equal to today's (2022) highest carbon taxes ($ 130–137 tCO2-1) that are observed in very few countries

Electricity cannot decarbonise the entire system alone, and hydrogen extends electricity's reach to hard-to-electrify sectors

The contribution of nuclear power in electricity production increases in the long-term in the decarbonisation scenarios. This is especially pronounced after 2050/60, when the wind and other renewable potentials are fully exploited and the additional electricity supply to meet the increasing demand needs to remain carbon-free.
