We are the first Portuguese company dedicated to the development and commercialisation of hydrogen purification technologies.
Amnis Pura, SA is one of the first companies dedicated to the development and commercialisation of hydrogen purification technologies, namely Pressure Swing Adsorption units (PSA).
Our strong R&D mentality dedicated to gas purification technologies allows us to develop and produce competitive solutions in line with the expansion of the hydrogen market in a circular and sustainable economy.
With the growing hydrogen market, Amnis Pura focuses on the purification of hydrogen from decentralised production processes such as ammonia cracking, methane reforming, waste and biomass gasification. Depending on their nature, these processes can be carried out under various operating conditions. They have different gas compositions that can vary over time during the production process. In this regard, Amnis Pura develops tailor-made solutions that are optimised specifically for the customer’s process, to meet the requirements of the strict ISO 14687-2.

The rapid growth of Amnis Pura demands additional area to accommodate all ongoing projects, and specially larger scale projects. The new area of ca. 900 m2 will significantly improve the production capacity and quality control. Paulo Ribeirinha, CEO, commented, “We will take this opportunity to implement quality management systems as…
The main goal of GAMMA project is to demonstrate the safe integration of fuels (biomethanol and NH3) and fuel systems (biomethanol reformer, NH3 cracker and 1 MW low-temperature PEM fuel cell) that will convert the hydrogen produced into electricity. The project approach, based on EU Commission strategy and IMO regulations,…
With the H2Driven legal agreement, the consortium will generate a new green hydrogen value chain in Portugal. The project goals are aligned with the reduction of CO2 emissions to the atmosphere, carbon sequestration and reductions of indirect GHG emissions. The Amnis Pura strategy is based on Vacuum Swing Adsorption (VPSA) technology. The…
With the project and contract formalization, the consortium starts the activitites in order to develop a new innovative industrial cluster aiming the production of sustainable biofuel based on green hydrogen and residual raw materials. In this context and based on circular economy and sustainability concepts, the Agenda M-ECO2 is completely…
