Storing energy and hydrogen and transporting it with standard logistics 

We offer iron oxide-based storage systems for the cost-efficient storage and transportation of hydrogen (H₂). The process consists of the reduction and oxidation of iron oxide or iron: During loading, the added H₂ reduces the iron oxide. The vapor released in the process can be reused in electrolysis. During discharge, water vapour is added. This causes the iron to oxidise, releasing H₂.

• Possibility of loss-free long-term storage
• Transport over long distances and with standard logistics
• 100 % higher efficiency in long-term electricity storage: doubling of the ‘electricity-to-electricity’ efficiency in the entire chain ‘renewable energy generation – H2 production – H2 storage – re-conversion to electricity’ chain up to 65 %
• Efficiencies of around 80 % for the ‘electricity-to-H₂ after storage’ process, thus ‘hydrogen production – loading the storage unit – discharging the hydrogen’ through an SOEC
• Up to 30% lower H2 production costs
• 50% less space required for H2 storage
• Up to 90% less water required for H2 production during storage charging
• Non-hazardous, as no H₂ can escape
• Simpler and therefore faster permit procedures
• Market-available, low-cost materials
• Fast loading/unloading
