thyssenkrupp nucera and Fraunhofer IKTS have inaugurated Germany’s first pilot manufacturing facility for strong oxide electrolysis cell (SOEC) stacks, positioned in Arnstadt, Thuringia.
Backed by the strategic partnership shaped in March 2024, the pilot plant marks a vital step towards commercializing high-efficiency electrolysis for hard-to-abate sectors. With a manufacturing capability of as much as 8 MW per 12 months, the ability goals to generate preliminary SOEC stack portions and optimize course of automation. Its inauguration attracted political and industrial stakeholders, underscoring the know-how’s perceived relevance to Germany’s hydrogen transition agenda.
SOEC techniques differentiate themselves by their use of excessive working temperatures (usually 700–900°C), which permits them to use industrial waste warmth—frequent in metal, cement, and chemical crops—to scale back electrical energy demand. Through the use of oxygen-conducting ceramic electrolytes and corrosion-resistant chromium-iron interconnectors, the SOEC stacks are engineered for each thermal resilience and streamlined manufacturing. These design options not solely help long-term sturdiness in harsh working environments but additionally allow automated manufacturing—a prerequisite for price competitiveness.
The emphasis on waste warmth utilization has turn out to be greater than an effectivity narrative—it’s now a essential requirement for sectors below tightening emissions caps and escalating vitality prices. Integrating SOEC techniques instantly with current warmth flows might enable operators to bypass each financial and bodily constraints of standard alkaline or PEM electrolysis. Furthermore, SOEC models can co-electrolyze CO₂ alongside H₂O, producing syngas for artificial fuels—including a carbon utilization dimension to inexperienced hydrogen methods.
But regardless of its theoretical benefits, SOEC stays in early industrial levels. Globally, alkaline and PEM electrolysis dominate the put in base, with over 90% of initiatives deploying these extra mature applied sciences, in response to IEA information. The transition from pilot to industrial-scale manufacturing stays a significant hurdle, involving important CAPEX, provide chain coordination, and risk-sharing frameworks between governments and business.
Along with offering technical insights, the Arnstadt plant is anticipated to information the design of a large-scale, absolutely automated manufacturing facility. Whereas no official timeline has been disclosed, each companions emphasised the pilot as a cornerstone for broader deployment throughout European hydrogen infrastructure.
