Introduction

About H2SITE:

H2SITE is a company that believes in European reindustrialization, created after 15 years of R&D with leading European research entities to develop cutting-edge technology.

We have built a unique membrane factory in the world, where we manufacture our units that provide a solution to the problem of hydrogen transport.

For our development, we rely on the local industrial ecosystem and first-rate international investors. Our products produce and/or separate H2 on-site from different feedstocks (ammonia, methanol, formic acid, syngas from waste…) and can save billions in infrastructure and accelerate the hydrogen economy.

We work to leave a better world for future generations by fighting climate change and facilitating the energy transition supported by renewable hydrogen.
