HyCS-Technology: simple and effective
Reduction and Oxidation
At its core, HyCS technology consists of the reduction and oxidation of iron (Fe): When loading the storage, the Fe is reduced by the supplied H2. Steam is released and can be used again in electrolysis. During discharge, steam is fed at the point of use, which can also come from the exhaust gas of a regeneration unit. This oxidizes the Fe and H2 is provided.
Highest storage density
Smart integration, especially with steam driven electrolysis (SOEC) and SOFC fuel cells, results in long-term power storage efficiencies of up to 100% higher than with alternative systems. HyCS technology thus reduces H2 generation and storage costs.
Reduced transport costs
HyCS technology means:
• Halving the space requirement for H2 storage
• 2 x as much H2/truck as in bundles of bottles
• Reduction of H2 generation and storage costs
For larger storage systems, HyCS already offers cost advantages. Due to the currently high costs of the reversible SOFC, HyCS storage units are currently more expensive than electric batteries with a storage capacity of <1 MWhel. Currently, HyCS storage systems are competitive by the help of investment subsidies, in the medium term they will be by raising cost-cutting potentials.
