I did not get the impression from the hints in ME2 that dark energy would be anything like that.
Iím thinking it is either Reaper technology or someone other than Ceberus believes Shepardís story and are experimenting with dark energy thinking it is outside of the Reapers scope of technology. The galaxy is way too dependent on the roadmap of technical advancement the Reapers left behind. Something outside that realm may be the key to bringing them down; a theory hinted at by TIM in ME2 but then thrown away when TIM wanted to save the Collector, so basically a guess on my part. Perhaps the Geth or the rachni, they are at least two species that know Shepard is telling the truth and know a little about Reaper technology.
