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
The HyCS® process principle offers numerous advantages compared to conventional H₂ storage. The graph shows: More than 2 kWh of hydrogen can be stored in one litre of HyCS® storage. This is about 2.5 to 5 times as much as in a pressure vessel (700/350 bar). And twice as much as can be stored with liquid hydrogen, in metal hydrides or similar approaches (LOHC). This makes the HyCS® storage system the most compact of all energy storage systems – of course also significantly more compact than Li-ion batteries (factor 10).
Best efficiency
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
