NewHydrogen reports progress on lowering the cost of producing green H2

NewHydrogen Inc. provided an update about the progress of its technology program and its efforts to reduce the cost of producing green hydrogen.

The company also reported that trends in 2022 point to hydrogen produced from renewable sources becoming a key component of a sustainable energy future.

Despite market uncertainty in many sectors, the global push toward realizing a green hydrogen economy remains extremely strong entering 2022. In Europe, the green hydrogen supply chain is growing rapidly, especially in Spain, France, and Germany. As noted at the recent conference of the Green Hydrogen Coalition, which NewHydrogen attended, the German government is transitioning its energy resources to green hydrogen and away from coal and natural gas, with all dispatchable energy to be hydrogen-sourced.

In the U.S., the recently passed federal infrastructure bill included:

Close to NewHydrogen’s home in Southern California, the HyDeal LA initiative is creating a green hydrogen hub across the Los Angeles area. The hub is building out support for production, transport, and storage of green hydrogen, as well as fueling for energy, transportation, industrial, maritime, and aviation industries. The hub is already creating significant new jobs supporting families in the LA area and providing a model of opportunities that will be available around the world.

The goal of NewHydrogen’s sponsored research at UCLA is to lower the cost of green hydrogen by eliminating or drastically reducing the use of precious metals in electrolyzers. Electrolyzers currently rely on rare earth materials such as iridium and platinum. These materials often account for nearly 50% of the cost of electrolyzers.

In 2021, the program developed a non-precious metal-based catalyst with significant improvement of oxygen evolution reaction (OER) in acidic conditions for proton exchange membrane (PEM) electrolyzers. Researchers then improved the catalyst performance by modifying the structure and optimizing loading conditions. Most recently, application of a unique surface engineering technique further improved the long-term stability of the catalyst. Higher stability implies reduced operating cost of electrolyzers in the longer term.

In a parallel effort, researchers have been developing hydrogen evolution reaction (HER) catalysts for alkaline electrolyzers. Their work is focused on developing platinum based HER catalysts that use significantly less platinum, as well as a totally new type of HER catalyst that does not use platinum at all. To date, significant progress has been made on both fronts. This is in line with the Company’s focus on developing OER catalysts to enable electrolyzers that cost less to manufacture and to operate.

“Prior to scaling up the process for studies with a prototype electrolyzer in late 2022, researchers will continue to explore additional improvements to both the OER and the HER catalysts to maximize the overall performance of an actual water electrolysis device,” said Dr. David Lee, CEO of NewHydrogen.
