Unlocking a New Source of Hydrogen
Hydrogen Will be a Primary Source for Electricity
The International Energy Agency projects hydrogen demand to skyrocket to 500 Mt/year by 2050. Geologic hydrogen has the potential to meet these demands at a production cost of < $1/kg of hydrogen.

Geologic hydrogen is generated from the natural mineralogical process of water reacting with iron minerals in rock. This process can be stimulated by injecting water into these rocks and optimizing the rate of chemical reactions. Engineering the production of geologic hydrogen will enable a sustainable and commercially competitive clean energy source.
The Problem
Limited Scalability of Natural Geologic Hydrogen Reservoirs
Discovering accumulations of naturally occurring geologic hydrogen is rare and challenging.

Hydrogen generation from mineralogical processes is limited due to suboptimal subsurface conditions.  The U.S. Department of Energy identified that development of novel engineering solutions to  stimulate the production of geologic hydrogen is key to unlocking the vast potential of this clean energy resource.

The Solution

Stimulated Geologic Hydrogen

Optimizing subsurface permeability and temperature in iron-rich rocks is key for stimulated geologic hydrogen.

Electrical Reservoir Stimulation creates high permeability fracture networks in the subsurface to maximize the reaction surface area for hydrogen generating mineralogical processes. High rates of geologic hydrogen production will accelerate the decarbonization of the energy industry.
How Electrical Reservoir Stimulation Increases the Production of Geologic Hydrogen
Electrical Reservoir Stimulation creates dense micro-fracture networks in low-permeability iron-rich rocks, which enables water to be injected and circulated. Stimulation increases the reactive surface area between the water and rock and results in higher volumes of hydrogen production from geological formations.

Electrical Reservoir Stimulation reservoir temperature and speed up the reaction kinetics for higher rates of geologic hydrogen production. Our technology will produce thousands of tons of geologic hydrogen annually.

Environmental Impact

Geologic hydrogen is needed to reach 17,000 TWh of hydrogen-based energy to reach net-zero emissions by 2050

Every million tons of geologic hydrogen saves 33 GWh of electricity.

Permeability management enhances hydrogen production

Geologic Hydrogen Production

Manufacturing hydrogen, a carbon-free fuel, is environmentally unfriendly and costly. However, an alternative approach to obtaining hydrogen may be possible. Some researchers believe abundant and potentially renewable sources of natural hydrogen exist underground. If proven true, this discovery could offer a more cost-effective solution.
