Problem
Current hydrogen production methods are either carbon-intensive or prohibitively expensive, hindering the widespread adoption of hydrogen as a clean fuel source. Traditional steam methane reforming (SMR) requires carbon capture, utilization, and storage (CCUS) to mitigate CO2 emissions, while water electrolysis demands significant energy input, driving up costs.
Solution
HiiROC offers a Thermal Plasma Electrolysis (TPE) process that produces low-cost, clean hydrogen from biomethane, flare gas, or natural gas without generating CO2 emissions. The proprietary plasma technology uses a fraction of the energy required by water electrolysis and eliminates the need for CCUS. As a byproduct, the TPE process yields solid carbon black, a valuable material with applications in industries such as tire manufacturing and road construction. HiiROC's modular units can be deployed at the point of use, reducing transportation and storage costs, and scaled from small operations to full-scale industrial plants.
Target Audience
HiiROC's primary customers include businesses requiring low-cost, zero-emission hydrogen, such as those in power generation, industrial decarbonization, and off-grid energy applications, as well as companies in the construction and transportation sectors.
