Water in
Water is the only feedstock. A compact on-board supply feeds the generation stage.
Feedstock: H₂O
How it works
Water in. Hydrogen on demand. Electricity out. Water back.
Inside the vehicle, Liquidynamix runs one continuous closed loop. Water is dissociated below 250°C in a membrane-free, temporally decoupled microwave redox-plasma reactor; the hydrogen is converted to electricity in a fuel cell; and the only exhaust is water, which returns to the loop. Nothing is produced until it is needed, and nothing is stored between production and use.
The Closed Loop
Five stages, one vehicle
Generation, conversion, and recovery happen in a single place, just in time. There is no tank of hydrogen to fill, because the hydrogen is made when the accelerator is pressed.
Redox split
The microwave redox-plasma reactor dissociates water below 250°C. Hydrogen and oxygen form in separate time windows.
Redox-plasma · <250°C
Hydrogen out
High-purity hydrogen is produced on demand, at the point of use, and consumed immediately.
Purity ≥99.99%
Fuel cell
The reversible solid oxide system converts hydrogen to electricity in under a minute.
rSOECS · <60 sec
Water back
The only exhaust is water, which returns to the loop. The cycle repeats.
Loop closed
The Technology
Two technologies, one integrated system
The loop is built on the two core Liquidynamix technologies, engineered to work as a single closed system with 5-stage heat recuperation.

5-stage heat recuperation
The heat of dissociation and conversion is recovered and reused across five stages, holding the loop to an efficiency of ≤33 kWh/kg. Energy stays in the system instead of escaping as waste. The reactor produces hydrogen and oxygen in alternating time windows, so no membrane is needed and no explosive mixture can form.
Why Just in Time
Hydrogen without the hydrogen problem
Central production and storage of hydrogen gas brings danger, price control, and leakage. Generating on board removes all three.
The central model
- Large central production plant
- Compression and cryogenic storage
- Pipeline or truck transport
- Dispensing losses and boil-off
- Exposed to central-market pricing
The Liquidynamix loop
- Water as the only feedstock
- Just-in-time generation on board
- Fuel cell conversion to electricity
- Exhaust water returned to the loop
- Insulated from central price control
Safety by Design
The safest way to make hydrogen
The reactor is built around one principle: hydrogen and oxygen are never produced at the same time.
No simultaneous gases
Oxygen and hydrogen evolve in alternating time windows, never in the same cell at the same moment. The explosive mixture that plagues conventional electrolyzers cannot form.
Nothing to fail
Gas separation is achieved by time and steam condensation, not by polymer membranes. There is no membrane to degrade, replace, or leak hydrogen across.
No bulk heating
Microwave redox cycling dissociates water below 250°C, and frequency-tracked resonance holds plasma gas temperature near 40°C under feedback control.
Specifications grounded in peer-reviewed literature: Serra et al., Nature Energy (2020), microwave water splitting below 250°C; Cook et al., Journal of Physics: Energy (2025), steam-argon plasma up to 80% plasma-power efficiency; Kwon et al., IEEE Transactions on Plasma Science (2017), resonance-tracked plasma gas at 40°C.
Built for the Road
Vehicle applications
The loop is designed for vehicles that run long, run heavy, and cannot afford to depend on hydrogen refueling infrastructure that barely exists.

Microgrids and remote power
0kg
Hydrogen stored on board
Zero-emission freight
Heavy and long-haul mobility needs range and rapid energy delivery. On-board generation delivers both without a hydrogen refueling network.
Independent power
The reversible system also operates as stationary storage, serving microgrids and critical infrastructure where fuel supply chains are fragile.
No fuel dependency
Water is available almost anywhere. A vehicle that makes its own hydrogen cannot be stranded by a fuel price spike or an empty station.
