> If we allow SMRs as a feasible tech, that aren't shipping and have no reliable cost estimates, we may as well also assume that advanced storage tech that isn't even shipping will be feasible. Yes, we should invest in both SMRs and advanced storage, not because we are assuming feasibility, but because we can't know their feasibility without trying them. > Storage companies have a far better track record of delivering on their promises than the nuclear industry does I disagree, and anyway I'm not saying "invest in SMRs instead of storage" but rather in addition to because it increases our odds of finding a viable solution and moreover a diverse grid is a robust grid (different energy sources are likely to have different failure modes, such that we have a fallback in case one source experiences a catastrophic failure).
