To meet ambitious climate neutrality targets, governments, investors, businesses and consumers are driving the transition to a more sustainable future. Hydrogen, and especially green hydrogen produced by means of water electrolysis using renewable energy, is a pivotal energy vector.
The Hydrogen Council has reported in its Hydrogen Insights Report 2021 that over 30 countries have already released hydrogen roadmaps and estimates that governments have allocated more than $70bn for public funding. Even though some obstacles such as a sustainable raw material strategy for critical electrolysis components still need to be resolved, Heraeus, a German multinational chemical company, believes in green hydrogen as the energy carrier of the future. In anticipation of these market trends, Heraeus is making significant investments to develop the technologies and capacities needed to enable the hydrogen scale up. Many technologies in the hydrogen economy rely on precious metal-based components and that is where Heraeus expertise comes into place.
Heraeus is a full-service precious metals provider, with specialised “full loop” expertise to help customers to address all challenges in the context of precious metals. Heraeus’s expertise includes:
- Catalysts for PEM fuel cells & electrolysers
- Catalysts for hydrogen purification
- Catalysts for emission abatement (e.g., in solid oxide fuel cells)
- Precursors for coatings and additives
- Precious Metal Trading (e.g., supply, pricing, risk management)
- Recycling services for all precious metal-containing materials
One of the key advantages of Heraeus’s catalyst solutions is their efficacy while remaining high performance. For example, with their new generation of anode catalysts for PEM electrolysers, a stack or electrolyser manufacturer can save up to 90% of Iridium compared to the industry benchmark while gaining a three times higher performance. This innovation provides cost savings and helps avoid the availability issues of scarce Iridium.
