HPQ Silicium updates green hydrogen extraction technology validation

HPQ Silicium Resources Inc. (HPQ) has provided an update on the ongoing validation of its EBH2 technology, designed for the extraction of green hydrogen. According to the company, the initial testing round, conducted by two PhDs with over 30 years of experience in renewable energy, confirmed the potential of the EBH2 Green Hydrogen Reactors (EBH2 GHR). These reactors use low voltage to power electrolyzers, generating a hydrogen and oxygen gas mixture that can be utilized for electricity production.

The scope of the testing was limited by mechanical equipment issues. However, the results were deemed positive enough for HPQ to maintain its exclusive option with EBH2 Systems SA, allowing for further validation tests. The company plans to resume testing as soon as feasible once new equipment solutions are in place.

These equipment problems prevented the validation of EBH2's key claim regarding its high conversion efficiency. EBH2 is currently working to resolve these technical challenges. HPQ's validation team aims to complete a new round of testing on the EBH2 GHR demonstrator as soon as possible.

EBH2 has filed a provisional patent for its proprietary, low-cost electrolysis technology, which it claims can efficiently extract hydrogen from water. Compared to commercially available electrolyzers, such as Polymer Electrolyte Membrane (PEM) and Alkaline technologies, HPQ's technology promises improvements. Current commercial solutions achieve conversion efficiencies between 50-70%, with projections suggesting over 80% only by 2050.

This development occurs amid a projected significant increase in demand for green hydrogen. A report by Jefferies forecasts that the global supply of electrolyzers by 2030 will be insufficient to meet anticipated demand, highlighting the need for new and more efficient production methods.
