At WD HydroTech, we’re developing technology that makes producing and storing green hydrogen simpler, cleaner, and more efficient. But what exactly does that mean — and why does hydrogen matter?
Let’s start from the beginning.
What Is Hydrogen and Why Does It Matter?
Hydrogen is the most abundant element in the universe — it makes up stars, planets, and even the water we drink. On Earth, it rarely exists on its own; instead, it’s bound up in molecules like water (H₂O) or hydrocarbons (like natural gas).
When separated, hydrogen gas (H₂) becomes a powerful energy carrier. It can be stored, transported, and used to power vehicles, heat buildings, or drive industrial processes — all without releasing carbon dioxide when it’s used. The only by-product from hydrogen fuel is pure water.
That’s why hydrogen is seen as a cornerstone of the clean energy transition.
Green Hydrogen: Made from Water and Renewable Power
Hydrogen can be made in several ways, but not all hydrogen is clean.Traditional methods, like reforming natural gas, emit significant CO₂.
Green hydrogen, on the other hand, is produced by splitting water (H₂O) into hydrogen and oxygen using renewable electricity — from wind, solar, or hydro power.
This process is called electrolysis, and it happens inside a device known as an electrolyser.
How Electrolysis Works
Inside an electrolyser, an electric current passes through water, separating it into hydrogen and oxygen:
2H₂O → 2H₂ + O₂
Hydrogen bubbles off at one side, oxygen at the other. If the electricity comes from renewable sources, the result is completely carbon-free hydrogen — truly green energy.
Our Membrane-Free Approach
Most electrolysers today use a polymer electrolyte membrane (PEM) to keep the gases separate while conducting electricity. While effective, PEM systems rely on expensive materials like platinum and iridium, require pure water, and are sensitive to contamination — making them costly and resource-intensive to scale.
Our membrane-free electrolysis system takes a different approach.
Instead of relying on a delicate membrane, our design uses advanced electrode engineering and smart fluid dynamics to naturally separate hydrogen and oxygen.
This simplifies the system dramatically:
No costly or fragile membranes to replace.
Greater tolerance for impurities in the water feedstock.
Longer lifespan and easier maintenance.
Lower capital and operating costs.
In other words, we’re making green hydrogen production more robust, accessible, and scalable — the way it needs to be for a global clean energy transition.
Why Hydrogen Needs to Be Compressed
Once produced, hydrogen gas is very light — so light that, at normal pressure, it takes up a huge amount of space. To store and transport it efficiently, hydrogen needs to be compressed to high pressures (up to 700–900 bar for vehicle use).
Compression also enables hydrogen to be delivered safely and economically — whether for refuelling stations, industrial users, or on-site energy storage.
Our hydrogen compression system, developed alongside our electrolyser, uses innovative piston and ionic liquid technology to deliver high-pressure hydrogen that’s:
Quieter and more efficient
Completely leak-free
Long-lasting and recyclable
Compatible with real-world hydrogen applications
The Complete H2G System
By combining our membrane-free electrolyser and advanced hydrogen compressor, we’re creating a fully integrated solution — H2G — that can produce and deliver clean hydrogen right where it’s needed.
From renewable power to high-pressure, high-purity hydrogen, our technology enables a more sustainable, decentralized energy future — one drop of water at a time.
In Summary
Hydrogen offers a way to store renewable energy, decarbonise hard-to-abate sectors, and strengthen energy independence. But to unlock its full potential, we need technology that’s affordable, durable, and scalable.
That’s what our team at WD HydroTech is building — practical innovation for a cleaner, quieter, hydrogen-powered world.
