Slaking the global thirst for energy could therefore get a substantial boost from improved technologies for producing fuels, plastics, food and other products with reduced inputs of energy.

In a comment article published April 26 in the journal Nature, two researchers from the Georgia Institute of Technology suggest seven energy-intensive separation processes they believe should be the top targets for research into low-energy purification technologies. Beyond cutting energy use, improved techniques for separating chemicals from mixtures would also reduce pollution, cut carbon dioxide emissions – and open up new ways to obtain critical resources the world needs.

Technologies applicable to those separation processes are at varying stages of development, the authors note. These alternative processes are now under-developed or expensive to scale up, and making them feasible for large-scale use could require a significant investment in research and development.
