  • Although renewable + bess still wins according to most recent studies on that matter, cost comparison between nuke and renewable / Bess is not that useful. Assumptions on the longevity of nuke reactors, for example, helps little if the fleet of reactors end up constantly break down and require repairment as in France and Belgium. So lcoe of nuke over long time span is highly uncertain and contingent; even in construction phase nuclear projects already entails higher risk in time and budget overrun than renewables. Plus the positive feedback loop of learning curve, evident in renewable and Bess, is not so visible for nuclear.

    What is more useful for sake of current policy discussion is deployment rate and scalability, which renewable plus batteries clearly wins.







  • I looked into the gwp* thing and it is more appropriate for macroscopic / global analysis than for the carbon accounting of individuals. if one reduces 1 unit per year of emission of short live GHG now, can they claim the positive climate effects by comparing with the counterfactual baseline, where they continue to emit the GHG with the same rate forever? That is the equivalent of claiming an infinite amount of emission reduction.

    in any case it is always possible to use a pulse response function to account for the gwp of any instantaneous emission increase/decrease, since gwp* is just the convolution of the pulse response over time.
