Sweetch Energy is at the forefront of osmotic power, also known as “blue energy,” a revolutionary technology that captures energy from the mixing of fresh and salt water. Using selective membranes, the company converts ionic movement into renewable electricity. Since its founding in 2015, Sweetch Energy has raised €40 million, employs 60 staff members, and aims to scale its technology to a 500 MW capacity—enough to power 1.5–2 million people. They collaborate with Rockwell Automation for remote control and monitoring systems.
