To fight the climate change, hydrogen plays an important role as a transportable carrier of energy. However, in order to make the turnaround happen, a lot of challenges need to be taggled and solved, beginning with producing the amount of hydrogen needed to fulfill the energy demand.

Today, most electrolytic hydrogen is produced via Alkaline Electrolysis. However, one single technology will not be sufficient to cover the complete demand. All technologies need to be employed in the best possible way. That is why Proton Exchange Membrane (PEM) electrolysis will play a particularly important role, especially in terms of production of Green Hydrogen. It is best suited to convert the fluctuating energy output of renewable energies, such as solar, hydro and wind energy.
For the mentioned PEM electrolysis precious metals are required – some of them being very scarce, like iridium – and they will be needed in significant quantities. Also, sequential processes like the purification of hydrogen, or the conversion into other forms for easier storage and transport, require precious metals.
Thus, precious metals are indispensable for the Hydrogen Revolution, and therefore the hydrogen ramp-up requires a raw material strategy. This strategy needs to cover three important aspects:
- Innovations to maximize the hydrogen output with the available raw materials or cover them with high performance alternatives, such as the Heraeus low-iridium materials
- Strategies to secure the supply with scarce materials like iridium and to manage the specific challenges like high price volatility with advanced precious metals trading services
- Additional capacities and workflows for the recycling of end-of-life materials to recover precious metals to establish a sustainable raw materials loop.
As a precious metals specialist, Heraeus is a skilled partner with high expertise in all necessary fields and has been investing significantly in R&D and hydrogen recycling. What is more, we are actively engaging in the Hydrogen Community, contributing to make the Hydrogen Revolution happen.
Heraeus is a member of various organizations that engage themselves in the Hydrogen economy, among others in Global Energy Solutions, Hydrogen Europe, Ammonia Energy Association and European Clean Hydrogen Alliance.
As well, we are actively taking part in several projects to accelerate the development of solutions that enable the hydrogen ramp up.
Project length: 01.04.2021 - 31.03.2025
Demonstration of the large-scale feasibility of PEM EL technology through the significant reduction of the Ir content with simultaneous highly efficient and long-lasting operation in respective MEA concepts.
Completed Projects
Project Duration: 01.06.2019 - 21.12.2022
Development of a scalable production technology for catalyst coated membranes and membrane electrode assemblies based on robust and high volume producable electrocatalysts, which fulfil the requirements of automotive mass market.
