Technology & Applications

Performance data from Dark Matter Materials (DMM) and the Interdisciplinary Research Center for Hydrogen Technologies at King Fahd University of Petroleum & Minerals (KFUPM) indicate that mineral-based catalysts can generate significant hydrogen volumes per gram under optimal conditions. DMM’s proprietary nanocomposite catalyst (made from earth-abundant metals) achieves hydrogen production rates up to ~310 mL/min per gram of catalystdmmaterials.com under mild conditions (water near 90 °C, with consistent water–catalyst contact). Academic research at KFUPM similarly reports that even traditional mineral catalysts (e.g. silicon-based mixtures in alkaline water) can sustain hydrogen generation on the order of tens of mL/min per gram at near-boiling temperaturesacademia.edu. These findings underscore that, given a sufficiently active catalyst and ~90 °C water, each gram of catalyst material can produce roughly 0.3 liters of H₂ per minute (or more) in a hydrogen-on-demand reactor.

Using the high-end figure (~0.31 L/min·g) as a benchmark, we can estimate the hydrogen output for different catalyst loadings in an on-demand reactor (assuming optimal conditions):

• 25 g catalyst: ~7.8 L/min (approximately 470 L/hour of hydrogen)

• 50 g catalyst: ~15.5 L/min (approximately 930 L/hour)

• 100 g catalyst: ~31.0 L/min (approximately 1860 L/hour)

These values scale roughly linearly with catalyst mass, illustrating the reactor’s on-demand scalability. In practice, a 25 g catalyst insert could generate on the order of hundreds of liters of H₂ per hour, while larger 50 g or 100 g inserts can produce well over a thousand liters of hydrogen per hour under the same conditions. (For context, even a more conservative catalyst efficiency of ~83 mL/min·g observed in KFUPM studiesacademia.edu would still yield ~2.1 L/min (~125 L/hr) with 25 g, demonstrating the robust output even at lower efficiency). These on-demand generation rates highlight the flexibility of the system – hydrogen production can be dialed up by simply increasing the catalyst amount or optimizing reaction conditions. All outputs are produced in real time, on-site, without the need for high-pressure storage or electrolysis, using just hot water and the mineral catalyst.

Note: The figures above represent performance under optimal laboratory conditions (≈90 °C water and good water-catalyst mixing) using data from DMM’s catalyst benchmarksdmmaterials.com. Actual field performance may start at lower rates but can be scaled up as needed, ensuring hydrogen is produced safely to meet demand.
