Abstract Energy storage is a critical component to supply local energy generation for both grid and off‐grid connected facilities communities, enabling localized independent secure power in cases of emergencies or unreliable traditional use. The high cost security importing fuel islanded grids has led growing need generate onsite with alternative renewable technologies while reducing facility costs electrical power. However, utility operators are being faced the challenges intermittent...
Abstract The EU Integrated Project Real‐SOFC aims at improving the understanding of degradation in SOFC stacks, and extending durability planar stacks to rates suitable for stationary application. As part project, three series each with two or four anode‐supported cells, were operated durations 3,000 h up 10,000 under varying fuel electrical load conditions. tests on these short conducted galvanostatically 800 700 °C dependence current‐density (0.3, 0.5 0.7 A cm –2 ), composition (hydrogen:...
Sunfire has performed large steps towards the commercialization of large-scale high-temperature (HTE) steam- and co-electrolysers by development several HTE generations.

Based on steam, electrolyser efficiencies more than 80%LHV were achieved. could be operated reversibly SOFC mode with electrical about 50%LHV. An optimized SOEC module increased power density, reduced complexity costs...
Abstract In the current landscape of high temperature electrolysis, mainly two solid oxide cell (SOC) technologies are being used: electrolyte‐supported and cathode‐supported SOCs. The geometrical differences, namely thickness electrolyte, can lead to vastly different operating temperatures. Since most phenomena affecting performance durability remain thermally activated, comparing stack be a difficult endeavor at best. While visible goal European project MultiPLHY consists Sunfire GmbH...

SOFC (solid oxide fuel cell) are known for a high electrical efficiency and especially the ESC (electrolyte supported cells) good robustness system operation. Nevertheless common concepts that use CPOX (catalytic partial oxidation) or SR (steam reforming) as processing still show disadvantages. systems will not pass efficiencies beyond 35% need additional water increases complexity, well initial operational costs. A technical solution those disadvantages is staged design. staxera GmbH has...
