In a project managed by the National Energy Technology Laboratory (NETL), GE Global Research has advanced a method to lower the energy requirement and cut the cost of recovering usable water from high-salinity brines. The new technology offers a way to turn a potential waste product into a usable source of water and minerals. Water and energy are surprisingly interconnected: much water is needed to generate electricity, and much energy is needed to purify water. The lowest energy method of water purification is typically a membrane process, such as reverse osmosis; however, some wastewaters are not good candidates for this because of very high salt concentrations. Reverse osmosis also leaves behind a brine with very high salinity that must be disposed of properly.

Just as the newest jet aircraft technologies require cutting edge innovations like carbon-fiber composites, polymers, and avionics to make them fly, the next generation of high efficiency and environmentally sound energy-producing technologies demand a very specific set of functional materials to make them capable of answering the nation’s increasing energy needs. NETL is internationally recognized for its success in designing, developing, and deploying functional materials tailored for use in energy applications and extreme service environments for next-generation energy technologies like solid oxide fuel cells, chemical looping, carbon capture, fuel processing, and many other applications.

Extreme environments are everywhere. From the pressures of the ultradeep ocean to the inferno heat of a power plant, harsh conditions make scientific ingenuity a necessity. To operate technology in extreme environments, new materials that can withstand those environments need to be created. Scientists at NETL are known for their ability to do just that. The three RS-25 engines used to propel NASA’s Space Shuttles are technological marvels. Fueled by liquid hydrogen, they generate intense heat and pressure to create the force necessary to escape the Earth’s atmosphere. During operation, an engine’s main combustion chambers can reach temperatures of 6,000 °F—far hotter than lava or molten steel.
