[[Nanotube membrane]]s of higher permeability than current generation of membranes may lead to eventual reduction in the footprint of RO desalination plants. It has also been suggested that the use of such membranes will lead to reduction in the energy needed for desalination.<ref name="LLNL">{{cite press release
