We have no evidence that it's possible to convert dark energy into 'ordinary' energy; actually, we don't know for sure that dark energy exists;
the universal expansion attributed to it may have some other cause. Our understanding of physics is far from complete, and there are many problems
with the standard model, from which the concept of dark energy is derived.
But - and this is the real issue - it is dark energy, according to the most popular current ideas, that causes the accelerating expansion of the
universe. So if you took dark energy out of the universe (by converting it to matter or 'ordinary' energy), you'd slow the expansion down, not
speed it up.
Keep an eye out for what turns up in the forthcoming Large Hadron Collider experiments. I'm willing to bet a modest sum that the Higgs boson won't
be found, nor any of the other hypothesized particles that supersymmetry demands exist.
