11:17 AM EDT, 10/08/2025 (MT Newswires) -- HydroGraph Clean Power ( HGRAF ) said Wednesday it has been awarded a new U.S. patent for a novel actuator technology that uses electrically conductive porous carbon materials, including HydroGraph's Fractal Graphene, to generate controlled mechanical force.

This is the first U.S. patent granted for an invention developed in HydroGraph's laboratories, and moves beyond its foundational graphene synthesis patents licensed from Kansas State University. The company has 11 patent applications pending covering various material innovations and applications.

"Fractal Graphene is unique in that its structure is more than 95 percent air, giving it an extraordinary ability to generate force when heated electrically," said Dr. Ranjith Divigalpitiya, HydroGraph's chief science officer and co-inventor of the patent.

"In effect, it is essentially electrically conducting air. This patent demonstrates how the intrinsic properties of our material can be translated into new types of actuators."

The invention has broad claims covering porous carbon materials such as carbon black, graphite, carbon nanotubes, and graphene foams. It has applications covering HVAC and building systems and consumer appliances like dishwashers.

HydroGraph shares are up $0.08, to $2.33, on the Canadian Securities Exchange.
