Hydrogen is very abundant however to get pure hydrogen we need to extract out everything else around it, or extract the Hydrogen out of everything else!
Water is H2O, H Hydrogen and O Oxygen. So we need to get the Hydrogen out of the water.
Using a Voltage applied to the water via an Anode (Positive) and Cathode (negative) bubbles are formed, these are bubbles of Oxygen and Hydrogen.
Now school level science has already created the 2 gases, we need to extract the H2 from the Oxygen though. Using Membranes, the small Hydrogen atoms can pass through these and the larger Oxygen atoms can’t – eureka! we have our basic system, correctly termed as a ‘Hydrogen Electrolysis system’.
The advantage of Hydrogen production is that the Hydrogen can be stored and used at a later date. It can be used directly in the internal combustion engine or in fuel cells to produce electricity on demand. The crucial advantage is no battery is needed to store the energy as with solar energy or wind energy that is not used directly.
Expand your knowledge further with this Alicat white paper on Nel Hydrogen, where you will see the following recommendation from Nel, a global hydrogen company:
“This has helped us simplify our test setups, increase reading accuracy/reduce variability, [and] is much easier for our technicians performing the test.”
– Philep Levesque, Nel Hydrogen manufacturing engineer
With Flow and Pressure sensors Premier Control Technologies can provide the instrumentation to measure the water flow, measure the Hydrogen flow and the pressure of both the water system and the High Purity Hydrogen Gas produced. You will find some instrument recommendations below:
The Alicat CODA Coriolis Flow Meter range offers direct mass flow measurements for exceptional accuracy in a broad array of precision ultra-low flow and high pressure applications.
The Rheonik Coriolis Flow Meters satisfies requirements for a higher pressure range - the high pressure ratings of up to 1379 bar and a wide fluid temperature range of -196°C and 350°C mean that the meters can be used in a variety of Hydrogen applications.
Our comprehensive range of pressure products spans mechanical pressure switches to electronic pressure control.
Equilibar back pressure regulators are well suited to Gas, Liquid and dual phase solutions. Reliable and simple to use with various materials of construction and tailor made for specific flow and pressure regimes, put us to the test! A perfect product example would be the Research Series. And if you would like to know how an Equilibar Back Pressure works, you can watch a video on YouTube here.
Alicat pressure products include standard pressure transducers and more advanced pressure controllers for use with your standard, vacuum, differential, closed loop and closed volume pressure applications. Dual valve pressure controllers are able to vent pressure within your process to offer no overshoot of system pressure.
Drastar's single and two-stage pressure regulation offers both high and low pressure processes covering a wide range of flow rates.
Mechanical pressure gauges come in many shapes and sizes and we can build to your specification.
