H2U Technologies and De PGM partnership; Capstone achieves 30% hydrogen blend

PGM catalysts, specifically platinum and iridium, present a significant chokepoint in the evolution of the hydrogen economy.

De Nora and H2U Technologies Inc signed a Joint Development Agreement (JDA) to examine the viability of newly identified non-platinum group metal (PGM) catalysts for green hydrogen production.

De Nora will help bring H2U’s innovative, earth-abundant catalysts to the electrolyser market. These new catalysts will fill a critical gap in developing low-cost green hydrogen, decreasing a significant cost barrier to growing the hydrogen value chain and promoting the energy transition.

De Nora has also confirmed new success with a non-platinum group metal (PGM) catalyst identified by H2U for green hydrogen production, marking a significant milestone in H2U’s catalyst discovery efforts. H2U’s electrocatalyst compounds for OER and HER reactions show viability for low-cost, scalable green hydrogen production by eliminating PGM in water electrolysis.

De Nora and H2U formed a partnership a year ago to exploit H2U’s proprietary Catalyst Discovery Engine system in order to discover and develop revolutionary electrocatalysts for hydrogen production via water electrolysis.

Capstone Green Energy achieves 30% hydrogen blend

Capstone Green Energy Corporation partnered with the US Department of Energy (DOE) – Argonne National Laboratory and the University of California, Irvine (UCI) has determined that the Capstone microturbine-based systems can safely perform on 30% hydrogen blended with natural gas without requiring costly hardware or software modifications.

The results indicate no deleterious effects when operating either turbine on up to 30% hydrogen by volume, including only slight increases in emissions, but well within current design specifications. The results also indicate a direction for attaining further NOx reductions when burning 100% hydrogen by exploiting the inherent flame stability of hydrogen.

In addition to testing on 30% hydrogen, Argonne Laboratory has also been running a Capstone C65 microturbine on 100% hydrogen, utilizing Capstone’s patented High Flame Speed injector design.
