Hydrogenera
Energy Outside the Box!

Since our founding, sustained R&D efforts have contributed to the continual improvement of our technology, setting the benchmark in the market.

Our electrolyzers are preferred for their reliability, innovative controlling system, and energy efficiency. Currently working on:

R&D

The principle of operation is identical to the traditional gasoline engine. Hydrogen fuel means zero CO2 emissions for transport industry.

By utilizing waste heat generated in hydrogen production, the metal hydride compressor helps increase the overall efficiency of the hydrogen systems. It reduces the reliance on energy-consuming electrical compression, while simultaneously decreasing the energy required for cooling. This approach not only improves energy efficiency but also significantly lowers operational costs.

Hydrogenera's story began long before it needed a name or a brand. It started at a parking lot in a Sofia neighbourhood.

To light up a hand-assembled electrolyser, you need a straight current. In a non-professional environment, the easiest way to obtain straight current is from a car dynamo. The electrolyser is tied down to the dynamo with a hose.

How does one know whether hydrogen is coming out through the hose?

Well, you light it up with a lighter!

Our Story

The efficiency was below zero, the engine almost stopped, and the flame was hard to see with the naked eye. But that was more than enough!

Once you know that you can produce fuel from water, the idea gets lodged in your brain, and everything that makes sense gets locked into the equation: water = energy.

We dared to go outside the box, not to accept the rules, but to see if there was another way. Our way!

Two maverick engineers, Drago, a graduate from the University of Chemical Technology and Metallurgy and Bobi, a graduate from the Technical University, armed with ideas, dreams, and most of all - stubbornness, set out on a trial-and-error path with the tireless enthusiasm of rebels, convinced they could change the status quo.

Today's discovery of hydrogen is not a discovery but a renaissance. What has drastically changed nowadays is the extraordinary technological improvements and the ability to electronically encode, program and harness a chemical process in a controlled environment.

Acho, a doyen in machine programming, joins Drago and Bobby. He began coding the process from start to finish. When they started 15 years ago, hydrogen was not a hype, on the contrary, it was crossed out and declared unprofitable and inapplicable for industrial use.

For 15 years, the three of them have been overturning the status quo and proving everybody wrong with every completed project. Along the way, they found more enthusiasts, unafraid of foregone conclusions, ready to rewrite the rules.

They still keep the first car they managed to start and drive around entirely on hydrogen.

"It takes us back in time to a field, to a Renault of indeterminate age, with the mileage scrolled hundreds of times, a long hose hooked up to a 200 bar bottle full of hydrogen."

Through gaining knowledge and experience, they understand that many solutions exist and that Hydrogenera is part of a global wave of change.

They are now working to address the pressing need for sustainable energy, harness climate change, and reduce pollution.

They continue to look through the critical eyes of engineers, but they always bring along childlike curiosity and the belief that they can make the impossible possible.

As an active member, we help shape the policies and projects driving Europe’s clean energy transition.

As a member, we engage with Nordic’s hydrogen ecosystems to exchange knowledge and drive industrial collaboration.
