Abstract
Detecting relic neutrinos is a longstanding goal in fundamental physics. Experimentally, this goal is extremely challenging as the required energy resolution is defined by the tiny neutrino masses ($\sim\SI{10}{\milli\electronvolt}$). The current consensus is that sufficient statistics together with the clean spectrum could only be achieved if beta decayers are attached to a solid state substrate. However, this inevitably imposes irreducible intrinsic limitations on the energy resolution coming from the Heisenberg's uncertainty principle. This limitation appears to be critical for the currently accepted decayer - Tritium. Here we analyze ways of mitigation of this limitation that are known at the moment and provide an up-to-date conclusion regarding the viability of using the Tritium for the relic neutrino detection.

Report
The manuscript estimates the graphene environmental effects that may prevent the expected neutrino mass measurements in PTOLEMY. While more robust studies are still needed to clarify the issue, such a critical examination is interesting and necessary.
I appreciate that the author tries to explain most of the physics with words, but the manuscript is not well written and should be improved significantly.
Requested changes
1. The title states that "long live the Tritium", but the main text suggests that Tritium can hardly work in practice. So I ask the author to either change the title or emphasize how a (new) Tritium method will be "long lived" .
2. I suggest the author explain the physics of each term in eq.(1), as now it is not mentioned at all. This also greatly helps the reader.
3. I suggest the author carefully read the manuscript to improve the writting. Now it is difficult to follow, and contains many typos, such as "can not eb stored", ''holds The delta-function", "stifness", "the lifetimes ... is pretty big" and so on. Almost all ''then'' should be replaced by ''than''.
