For anyone who hasn't seen it, here's what the translated novel has to say about the Tenseigan so far: According to Toneri, Ootsutsuki Hamura was also the originator of the tenseigan. Using the great power of the tenseigan, he brought order and stability to the world of the moon. Even after his death, the people of the moon treated “Hamura’s tenseigan” as a treasure. They enshrined it as a religious object, and devoted a plan to eternally preserving it.

The tenseigan however, was not limited to Hamura’s tenseigan only. By implanting the Hyuuga clan’s byakugan, those who inherited the Ootsutsuki’s blood could manifest and acquire a new tenseigan. By combining the chakra of both clans, the byakugan would transform into the tenseigan. |Source

Not a lot to go by, but still better than the movie which told us nothing. One thing of note is that Hamura apparently retained his eyes until death. So assuming the clan's method of enshrining Hamura's Tenseigan was transforming it into the energy vessel, it's probably wrong for the wiki to list Hamura as a user of said vessel. Also, I don't think the term "energy vessel" has appeared in the novel so far, nor has any mention of natural energy. And both the movie and novel claim that the "Tenseigan" inside the island with Hamura's face (that possibly becomes the golem at the end of the film?) is just a replica, not the outer casing like the article currently claims — the movie just depicts the thing inconsistently.
