Introduction

About H2SITE:

H2SITE is a deep-tech start-up that uses advanced membrane reactor technology to solve the hydrogen transport problem by converting hydrogen carriers with well-known supply chains and separating hydrogen gas blends into fuel cell purity hydrogen.

Founded in 2020 in Bilbao, Spain, it emerged as a spin-off from two renowned research and development centers in collaboration with ENGIE New Ventures as its first industrial investor: TECNALIA, the largest private research center in Southern Europe specializing in membranes and material sciences among other fields, and the Eindhoven University of Technology (TUe), a reference in process intensification. Headquartered in Loiu, the company employs over 60 team members in its unique membrane production facilities located in Loiu, Spain.

We have built a membrane factory that is unique in the world, where we manufacture our units that provide solutions for the hydrogen transport problem. For our development we rely on the local industrial ecosystem and top-level international investors.

We have developed a technology of membrane reactors for the separation and production of hydrogen in situ from different feedstocks, such as ammonia, methanol, formic acid, syngas from waste…
