Compressed blocks of pulverized coal can be used as the basis of sunlight-powered off-grid water purification. The technology is currently being progressed by commercial partners toward pilot-scale production of drinking water.

Desalination adoption outpaces the development of effective strategies for managing the concentrated brine streams it produces. Electrochemical water-salt splitting to generate useful chemicals is an ideal method to valorize wastewater from desalination and incentivize its collection.

The fast-rising number of desalination plants worldwide—now almost 16,000, with capacity concentrated in the Middle East and North Africa—quench a growing thirst for freshwater but create a salty dilemma as well: how to deal with all the chemical-laden leftover brine. In a UN-backed paper, experts estimate the freshwater output capacity of desalination plants at 95 million cubic meters per day—comparable
