Ongoing Projects

ValorH2 focuses on researching technologies, materials, and processes throughout various stages of the hydrogen value chain. These stages include generation, compression, storage, transport, and utilization. Specifically, our research is geared towards two main areas:

  1. Hydrogen refueling for vehicles as an alternative fuel source.
  2. Methanation of CO2 recovered in the chemical industry, wherein it serves as a chemical reagent.

Our primary objectives revolve around enhancing efficiency, reducing economic costs, and minimizing the carbon footprint at every stage of the process.

The objective of the Iron NPE project is to develop a non-propulsive energy system that utilizes a renewable hydrogen fuel cell. This project is undertaken within the framework of the AIRBUS ZEROe initiative.

As a consortium member, Ariema will take responsibility for constructing a multistack alkaline electrolyzer with a capacity ranging from 1 to 2 MW.

We are conducting a study on innovative technologies aimed at facilitating the transition of the metallurgical industry towards a circular economy. The focus of this study is centered around two key aspects:

  1. Recovery of by-products from the production process itself.
  2. Decarbonization through the incorporation of renewable raw materials.
