Decoupled Water Electrolysis (DWE)
H2Pro’s electrolysis technology is based on a method known as Decoupled Water Electrolysis (DWE), which separates the hydrogen and oxygen evolution reactions in time rather than space. Unlike conventional electrolysis methods that produce hydrogen and oxygen simultaneously at different electrodes, DWE operates in two distinct phases. H2Pro's proprietary DWE method employs a bifunctional electrode and a “battery-like” electrode that charges and discharges. In phase one, hydrogen is generated at the bifunctional electrode while the battery electrode charges - transforming from nickel hydroxide to nickel oxyhydroxide. No oxygen is released in this step, eliminating the risk of gas mixing. In phase two, the current is reversed. Oxygen is produced at the bifunctional electrode while the battery electrode discharges - converting back from nickel oxyhydroxide to nickel hydroxide. No hydrogen is released during this phase.
This membrane-less, temporally separated process enables greater operational flexibility, improved safety, and high efficiency under intermittent power conditions. Although individual DWE cells alternate between hydrogen and oxygen generation, multiple cells are operated in parallel to ensure continuous overall gas production.

Nat Energy 4, 786–795 (2019). https://doi.org/10.1038/s41560-019-0462-7] Out of approximately 33.3 kWh of usable energy per kg hydrogen,
this gives the two-step electrolysis process a theoretical maximum energy efficiency of approximately 79.6 percent for storing electrical energy in hydrogen. The energy then needs to be converted back to electricity, which
in practice, using fuel cells, results in further energy losses.
