Saltworks specializes in recycling waste water or using desalination on saline water. It focuses on challenging water sources found in industrial settings such as shale gas, oil sands and mining.
CEO Benjamin Sparrow said: “BP's investment will immediately go to work as we construct our new manufacturing facility and further grow our field operations team.
“After successful product uptake in Australia, California, Texas, and Pennsylvania, we are extremely pleased to welcome BP to our shareholder base. BP's investment will increase our scale and our reach.”
The investment follows others made by companies, including Cenovus Energy, ConocoPhillips and Teck Resources. It also comes after successful test projects between BP and Saltworks.
BP Ventures now manages over 30 investments with committed capital of over $200m.
