I think you mean there's no instantaneous power at the zero crossings.

Well, since the NET voltage is always zero at a voltage node when
the forward power and reflected power are equal, the instantaneous
voltage is always zero, i.e. the steady-state voltage is always
zero.

I've never actually seen the voltage at a node in a standing wave
pattern referred to as an instantaneous voltage - especially considering
that it doesn't vary with time. Instantaneous usually means the
solution to a function f(t) at time t (not f(x) and position x.) Nodes
and zero crossings aren't necessarily the same thing.
