Hydrogen Refinery (H2R) develops the Plasma Electrolysis System (PES), a modular, catalyst-free technology that uses microwave-induced plasma and AI control to break down waste hydrocarbons such as non-recyclable plastics and biogas into pure hydrogen, syngas, and solid carbon with no gaseous emissions. The resulting outputs support production of hydrogen, ammonia, methanol, synthetic marine diesel, and sustainable aviation fuel for industrial and energy customers.
