How OneH2 Makes Hydrogen Fuel

Our 4-Step Hydrogen Production Process

The OneH2 hydrogen fuel generation process has four basic stages.


Water Treatment
The conventional hydrogen generation process requires purified water.



Through either Electrolysis or Steam Methane Reforming, raw hydrogen is generated from feedstock.


Fuel Purification

Raw hydrogen upgrades to pure hydrogen at low pressure.


Fuel Compression

Pure hydrogen upgrades to ready-to-use hydrogen fuel suitable for lift trucks, warehousing vehicles or any commercial application.

H400 System (400 KG / Day) - OneH2 Generation System

W400 Module

Purifies and stores potable/city water ready to generate hydrogen.

g400 Module

Combines purified water (from 400) and methane (from Grid) to generate raw hydrogen gas. Electrolyser option available.

p400 Module

Purified gas recieved from G400 to >99.99% purity and conformance with SAE J2719 standard.

c200 Module

Compresses gas received from P400 to 13,500 PSIG / 930 BAR. Interfaces with OneH2 gas distribution modules.

Making Hydrogen
Profitable for
Our Partners

OneH2 developed new hydrogen solutions based on the most economically viable options for our partners, pioneering simple, reliable and affordable technology that you can count on every day. We chose a method of production that, while not fully independent of fossil fuels, avoids the substantial costs associated with setting up a new energy infrastructure while paving the way for greener options.

SMR OneH2 Generation Process

If you’re using a OneH2 SMR generation process, three utilities are needed.






* usually as natural gas

While SMR results in some carbon emissions, hydrogen is still a major improvement to natural gas, diesel, propane, and other fossil fuels. OneH2, and most of the globe uses the Carbon Intensity Index to measure the carbon output for all the factors of fuel. These include how it’s made, how it got there, and how much energy it provides. A lower score indicates fewer emissions.

CI values are not open to interpretation. For comparison purposes, the CI of Gasoline is 101, CNG is 80, Ethanol is 70, and recharging a battery electric vehicle is 27. On-site generated hydrogen using OneH2’s SMR system with fossil-based natural gas has a CI of 42.3.

Our hydrogen is mainly produced via SMR, but we also offer hydrogen produced with electrolysis. If you’re using an electrolysis OneH2 generation upgrade module, only electricity and water are needed.


Using the H-Series OneH2 hydrogen generators and routine utility hookups, our partners can supply their operations with a consistent supply of fuel.

From a single H200 unit for facilities with just a small fleet of off-road vehicles such as forklifts to multiple H400 units supplemented by trailer swaps, OneH2 will get you set up with the configuration that keeps your business working hard.
