As you note, ultracold neutrons are an old and respected niche of physics - and these known cold neutrons are easily detectable and bear not the slightest resemblance to the W-L concoction – which IMHO is almost in the category of brain-dead.
How can low energy be anything other than ultra-cold?
In their defense, W-L can make dandy presentation slides. They should open
up a graphics design studio.

Nickel, to take one example, has a high neutron optical
potential [1]. When neutrons are very cold, they will reflect off of the
nickel atoms to a certain extent. A typical LENR experiment shows power on
the order of watts to tens of watts. If neutron capture were responsible
for that kind of power generation, there would be so many neutrons being
generated that a significant portion would reflect off of the nickel
substrate atoms, thermalize and exit the system, to be picked up in GM
counters.
When neutrons have in fact been detected, the levels have
usually been at the threshold of the neutron detector. One presumes that if
there were a large number of thermalized neutrons exiting a system, they
would would be in quantities sufficient to go well beyond the threshold of
detection.
None of these are my own arguments. I am repeating what I
have heard elsewhere. Importantly, I am unfamiliar with the quantities that
would be needed to model this system and test these assumptions. But it
seems reasonable to ask an explanation predicated upon neutron capture to
address these points.
