1. There is no "10 year" time limit. There is a window of time to keep our overall warming below 1.5c, which is virtually impossible regardless of which policies we choose to pursue, collectively.

2. There is no indication that we will be able to produce lithium-ion batteries with a high enough wh/kg density to create high enough energy storage capacity to replace carbon-based energy sources. Until such a time as that technology becomes possible and production-ready, we will need other sources of energy.

Not building nuclear with the assumption that grid-scale battery storage will become feasible is a potentially catastrophic policy decision.
