MUMBAI, India, July 25 -- Intellectual Property India has published a patent application (202517064724 A) filed by Carbon Technology Holdings, Llc, Oakdale, U.S.A., on July 7, for 'process and systems for carbon-negative and water-positive hydrogen production.'
Inventor(s) include Mennell, James A.; Daugaard, Daren; and Slack, Dustin.
The application for the patent was published on July 25, under issue no. 30/2025.
According to the abstract released by the Intellectual Property India: "The disclosed technology provides processes for producing hydrogen that is renewable, has negative carbon intensity, and is associated with net water production. The hydrogen is economically, environmentally, and socially superior to conventional hydrogen via steam reforming of natural gas or electrolysis of water. Some variations provide a process for manufacturing carbon-negative hydrogen and optionally activated carbon, comprising: feeding biomass into a first heated vessel or zone to generate dried biomass and a first recovered water stream; feeding the dried biomass into a second heated vessel or zone to pyrolyze the dried biomass, generating a biocatalyst and a biogas; feeding the biocatalyst, the first recovered water stream, and biogas to a third heated vessel or zone for biocatalytic conversion, thereby generating H2, CO, and optionally activated carbon; and recovering the hydrogen. The H2 is carbon-negative hydrogen characterized by a carbon intensity less than 0 kg CO2e per metric ton H2."
The patent application was internationally filed on Dec. 21, 2023, under International application No.PCT/US2023/085470.
