Next-generation Hydrogen Storage
Hydrogen has tremendous potential as a fuel and energy storage method.
Commercial technologies for hydrogen storage and transport still rely on high pressure and cryogenically cooled liquid hydrogen, at -253 °C (-423 °F). These hydrogen storage techniques are essentially unchanged over the past 125 years.
H₂Unity is advancing the next-generation of hydrogen storage, with the goal of unlocking large-scale use of hydrogen, as a cost-competitive replacement for diesel, gasoline and jet-fuel.
Growth in Hydrogen Supply
Hydrogen from Renewable Energy
“Green hydrogen” is produced using renewable energy sources, like solar and wind. As renewable energy continues to expand, hydrogen production expands.
Hydrogen from Geology
Recent discoveries in geophysics indicate the presence of vast reserves of sub-surface hydrogen (“Geologic hydrogen”), in geologic structures that have largely been ignored by traditional energy companies. In January 2025, the US Geological Survey launched its Geologic hydrogen website:

Exploration and extraction techniques are in development, driven by the scale of Geologic Hydrogen deposits, which are projected to contain up to 80 times the energy content found in all known fossil fuels.
Hydrogen’s bottleneck: storage & logistics
The high costs of traditional hydrogen storage and transport technologies arise from hydrogen’s properties:
Low density as a gas, at atmospheric pressure and ambient temperature.
H₂ gas causes metal embrittlement in most alloys of iron, aluminum and titanium.
Tendency for pressurized H₂ gas to leak from most pipes and containers.
Safety systems required to address H₂ gas’ broad flammability range.
Energy penalties for compression and cryo-cooling of H₂.
Despite growing supplies of hydrogen, the high cost of current commercial hydrogen storage and transportation are the bottleneck to market growth.
Breakthrough Innovation
H₂Unity is commercializing breakthrough technology in hydrogen storage, that is proprietary and patented, developed by a world leading research institution.
In addition, we are establishing collaborative technology partnerships to unify the hydrogen market into a cost-competitive energy ecosystem, that connects:
Suppliers
Storage
Logistics
Point-of-use
For hydrogen to become a cost-competitive replacement for conventional transportation fuels and an energy storage method, the technology must have the following advantages:
High energy density at ambient temperature
No compression
Zero self-discharge
Long-term stability
H₂Unity is targeting a cost-parity replacement solution for current transportation fuels (diesel, gasoline and kerosene).
