org-element-block-name-alist is defined in org-element.el,
so you need to load that file before you can use it. Find
the place where you are setting it in your init.el and modify
it as follows:

--8<---------------cut here---------------start------------->8---
...
(require 'org-element)
(add-to-list 'org-element-block-name-alist
             '("HTML" . org-element-export-block-parser))
...
--8<---------------cut here---------------end--------------->8---

But I don't think you need to modify it at all: I start with a
minimal init file, do a (require 'ox-html) and
org-element-block-name-alist already contains the HTML element above.
This is with

Org-mode version 8.3beta (release_8.3beta-40-g9cf3c4)

YMMV of course if you are using a different version: there might be
a bug that has been fixed more recently - I haven't checked.
