  • 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.













  • This is basically common knowledge now. CSIRO report pointed to similar conclusions for several years, at least since 2021 when I started to notice.

    What is relevant to real life (since Australia probably never will get nukes) is that even assignning system costs only onto VRE, they are still almost the same LCoE in a 90% VRE system. This is again consistent with previous reports.

    After Australia pass 100% VRE, exporting green hydrogen in the regional market will probably handle the last remaining flexibility needs. Exporting electricity directly to SE Asia is less likely but still a possibility.
