The Emerge Alliance[1] is an industry group that has been working on this issue, though they've started with a spec for datacenters (as stephen_g alludes to). I think the consensus is that it is definitely more efficient to convert to DC at a single point, but one located as physically close to the loads as is practical, because of the line losses mentioned. Definitely something that will make sense for commercial buildings/campuses and multi-unit residential, and single family homes are not too far behind, I think. I can picture homes sometime soon just being wired for AC in the kitchen/garage/utility rooms with a LV DC grid elsewhere. The lower safety requirements for low-voltage really open up possibilities for system design and integration in the built environment. http://www.emergealliance.org/About/Vision.aspx |
