Soluciones para producción in-situ de H2 de alta calidad

Ahorrar costes para la industria hoy y hacer posible la movilidad de mañana.
What we do

Our world is to produce on-site high-quality hydrogen



Our proprietary technology supported by various patents makes the difference. Thanks to the know-how of advanced A-SMR reactor design,

we are a hightech!



To save costly transportation and avoid to waste compression energy, with no leaks linked to the compression/ decompression phases.


Relevant reduction of cost for available Nm3 of Hydrogen.


On-site production avoids energy waste for compression, transportation and leaks.


Combine our systems to achieve the desired production level: from 2 Nm3/h to what you need, with maximum availability.

The Hydrogen World


On-site H2 production makes possible what was previously unthinkable. To have high-quality hydrogen, and to have It at a low cost, allowing cost savings thanks to its production from GN. Hydrogen is used in different processes such as to protect materials from oxidation, to create controlled atmospheres, to react with various raw materials or to hydrogenate fats and oils.


By taking advantage of renewable feedstocks, such as BIOGAS, BIOETHANOL, BIOMETHANOL, green hydrogen can be produced. This technology becomes the bridge to 100% sustainable mobility. If the circular economy is the biggest challenge at a global level, we can make it a reality thanks to the application of our patented membrane technology.

H2 separation

Processes that require the separation of flows with low H2 content. High purity hydrogen can be recovered from GN and other gases.

H2 storage

Centralized or distributed systems allow H2 storage. Storage tanks and Fuel Cells (FC) are key in this area of application. Tanks are part of any refilling stations. Fuel Cell power makes H2 distribution a reality, as a replacement system for empties FC and especially in mobility-related applications.

H2 and CHP

The combined production of hydrogen and other fluxes (heat, power, CO, CO2 ...) is done just adding different modules to our systems. It is possible to achieve maximum efficiency and minimum environmental impact.

We started servicing the industry, but our future is tied-up the green mobility

Our History

+ 10 years of continuous evolution

All started 10 years ago, when TECNALIA, the Technological Research and Development Centre, and the Technological University of EIndhoven-TUE began collaborating on European projects around metal deposition technologies.

In 2018 we won the second EARTO Innovation award.

In 2019 the company was founded in Bilbao.

2020 has been the year of acceleration towards commercial customers, thanks to ENGIE’s investment in the company, through its corporate venture capital arm ENGIE New Ventures.


H2SITE History

Who we are?

H2SITE is formed by professionals with long experience and diverse backgrounds.
Some of us have been in the project from the beginning. We accumulate relevant scientific and technological experience. Others have joined more recently with experience in the commercial, management and production fields to realize business development and market growth.

H2SITE in associations and platforms

We promote awareness based on the diffusion of the use of hydrogen in all areas, from industry to green mobility. For this reason, we maintain and develop an active role wherever we are.
