In my large latex document, I have some figures which take a considerable height of the page (80-95%). Latex puts each of these figures alone on a page, aligned on top. I would like to have each figure aligned vertically to center. Is that possible, and if so, how? 🙂

A float environment is hardly warranted here, since you seem to require a specific location for your tabular environment. Why not just do the following?
See this for more details on what floats are used for.
\documentclass{article}
\usepackage{caption}
\usepackage{lipsum}
\begin{document}
\section{Foobar}
Please refer to Table~\ref{fig:mytable} for more details.
\lipsum[1]
\vspace*{\fill}
{
\centering
\begin{tabular}{c|c|c|c}
28 & 1 & (1)(28) & 28 \\
27 & 0 & (0)(27) & 0 \\
26 & 1 & (1)(26) & 26 \\
25 & 2 & (2)(25) & 50 \\
24 & 3 & (3)(24) & 72 \\
\end{tabular}
\captionof{table}{A magnificent table}
\label{fig:mytable}
}
\vspace*{\fill}
\clearpage
\end{document}
You can capture the tallest image in a box, which you can then use to measure the height by which you want/have to raise the other not-so-tall images:
\documentclass[final,5p,times]{elsarticle}
\usepackage{subcaption}
\begin{document}
\begin{figure*}[htpb]
\setbox9=\hbox{\includegraphics[width=.3\linewidth]{example-image-1x1}}% Capture tallest image in box 9
\subcaptionbox{Curl-free potential singularities}
{\raisebox{\dimexpr\ht9-\height}{\includegraphics[width=.3\linewidth]{example-image-a}}} \hfill
\subcaptionbox{Divergence-free potential singularities}
{\raisebox{\dimexpr\ht9-\height}{\includegraphics[width=.3\linewidth]{example-image-b}}} \hfill
\subcaptionbox{Vector field potentials singularities}{\includegraphics[width=.3\linewidth]
{example-image-1x1}}
\end{figure*}
\end{document}
\ht9 represents the height of box 9, while \height is the height of <stuff> in \raisebox{<height>}{<stuff>}.
As reference see References for \dimexpr and \numexpr.

I'm curious which documentclass you're using, as "normal" behavior (as defined in the LaTeX kernel file
latex.ltx) is to center the float vertically on a floats-only page.If you need to get the float to be centered on a floats-only page, you should add the following instructions to your preamble.
To have the figure/table be aligned at the top, you would delete the
plus 1filafter0ptin the instruction setting the length of the\@fptopvariable.By default, LaTeX will place a large float on a page by itself if the float's height exceeds 50% of the parameter
\textheight. To change this threshold to, say,0.75, you should issue the command\renewcommand\floatpagefraction{0.75}. Happy TeXing!
