Clenersys – Green Hydrogen Technologies
Clenersys Inc is a spin-off venture launched in 2021 by Nano-C and its business partners. Incubated in stealth mode, Clenersys’ technology innovations, CORETM and PRIMETM, are focused on addressing the challenge of creating commercially viable solutions for the large scale production of green hydrogen and its use in storage nodes or transportation. Substantial reductions in the cost of the key components used in PEM based hydrogen fuel cells and Electrolyzers can be realized by taking advantage of the unique properties of Nano-C’s single walled carbon nanotube products.
Clenersys is currently seeking development partners from OEMs including bipolar plate manufacturers, FC and Electrolyzer stack builders and system integrators.

Corrosion Resistant Bipolar Plates – CORE™
Corrosion of metallic bipolar plates in PEMFCs reduces performance, lifetime and increases system downtime, maintenance cost and overall total cost of ownership (TCO). The first Clenersys innovation, CORE™ addresses this problem by combining the low-cost manufacturing advantages of stamped steel with the proven electrochemistry and high durability of an ink based nanostructured carbon coating. This technology can overcome the major hurdles faced by competing approaches that use higher cost materials like gold or slow methods like curing of carbon composites or energy intensive manufacturing methods like physical vapor deposition. At the heart of CORE™ is an ultrathin layer of single walled carbon nanotubes (SWCNT) on a metallic substrates deposited at low temperatures using proprietary, water based SWCNT inks.
Advanced Proton Conductive Membranes – PRIME™
PRIME™ (Proton Reservoir and Intrinsic Mobility Enhancer) is a novel proton conductive stack designed for enhanced proton density and mobility in the membrane electrode assembly and compatible with R2R manufacturing lines. Anticipated PRIMETM benefits are improved fuel cell and electrolyzer efficiencies, a thinner membrane electrode assembly (MEA) with improved mechanical strength, reduced internal cell resistance and improved durability. As a nano-hybrid designed with molecular level structural features, PRIMETM is compatible with low and high temperature proton conductive polymers. It can overcome the ‘leach-out’ issue faced by composite ionic membranes doped with conventional solid acids. PRIME targets a 20% to 50% increase in energy density, resulting in a corresponding reduction in the weight and volume of the stack delivering comparable power—a coveted goal for military and transportation applications.
Both CORETM and PRIMETM technologies are protected by utility and methods patents allowed in the USA, Japan, Korea, China, Canada, UK, Germany, France, Italy, Sweden and Czech.
