The AZETEC Truck Fueling Solution

Hydrogen (H2) for the AZETEC Project will come from an industrial gas supplier in Alberta that makes H2 using natural gas and steam-methane reforming (SMR) technology. This merchant H2 will be transported via tube trailer to the truck fueling station location, where HTEC will put it through an onsite purification and compression process to make it ready for truck refueling.

The Process

Industrial gas suppliers deliver hydrogen by tube trailer to the AZETEC Project fueling site. The H2 is at a pressure of 180 bar (2,600 psi).

Once onsite, HTEC purifies the H2 to meet fuel cell purity requirements (99.999%), using pressure swing adsorption (PSA) technology. HTEC then compresses the H2 to bring it up to the pressure required for truck refueling.

H2 is stored onsite using HTEC’s modular, mobile H2 storage solution, the PowerCube, at a pressure of up to 450 bar (6,500 psi). PowerCube units have a small footprint and can be integrated to provide the required amount of H2 storage.

The zero-emission fuel cell trucks fill up with H2, safely and quickly, at HTEC’s industrial H2 fueling station. The trucks require hydrogen at 350 bar (5,000 psi).

Making Hydrogen From Natural Gas

Most hydrogen today is made by steam-methane reformation of natural gas. It’s a safe, cost-effective, and efficient process where methane (CH4) —the main component in natural gas—reacts with high-temperature steam (usually in the presence of a catalyst) to separate the hydrogen from other molecules.
