INOD® Osmotic Power System is a groundbreaking technology developed by Sweetch Energy that utilizes biomaterial-based membranes to generate electricity from osmotic power. Inspired by nanofluidic research, INOD® features nanoscale pores that selectively channel ions when freshwater and seawater meet, creating a continuous ionic current that is converted into clean energy.

This modular and compact system is constructed from eco-friendly biomaterials, ensuring sustainable power generation without noise, emissions, or chemical waste. Demonstrator sites like OPUS-1 in the Rhône delta and partnerships with industry leaders such as EDF Hydro and Rockwell Automation showcase the industrial viability of INOD® at scale.

INOD® offers baseload renewable electricity that complements intermittent renewables, enhances energy security, and contributes to reducing carbon emissions by tapping into the vast potential of global salinity gradients. Its clean, efficient, and scalable design positions it as a transformative solution in the ongoing energy transition.
