Projektbeschreibung
Mit erneuerbarer Solarwärme und Sonnenenergie effizient und umweltfreundlich Wasserstoff erzeugen
Die Hochtemperatur-Festoxidelektrolyse kann zur emissionsfreien Erzeugung umweltfreundlichen Wasserstoffs eingesetzt werden, um damit den Wasserstoffbedarf bei industriellen Anwendungen zu decken. Besonders nachhaltig ist sie dann, wenn sie mit erneuerbaren Energiequellen gekoppelt wird. Diese Quellen liefern jedoch unstetig und oft nicht die hohen Temperaturen, die für die Dampferzeugung im Elektrolyseprozess gebraucht werden. Das EU-finanzierte Projekt PROMETEO wird die Kopplung der Festoxidelektrolyse (des Wasserstoffgenerators) mit erneuerbarer Wärme und Strom aus Sonnenenergie, die zeitweise zur Verfügung stehen, mithilfe eines Wärmeenergiemanagementsystems optimieren. Das Wärmeenergiemanagementsystem sorgt dafür, dass immer genug Wärme zur Verfügung steht, um die Festoxidelektrolyse kostengünstig und mit hoher Effizienz zu betreiben. Der PROMETEO-Prototyp wird drei industrielle Anwendungen für die Endnutzung berücksichtigen.
Ziel
PROMETEO aims at producing green hydrogen from renewable heat & power sources by high temperature electrolysis in areas of low electricity prices associated to photovoltaic or wind.
Solid Oxide Electrolysis (SOE) is a highly efficient technology to convert heat & power into hydrogen from water usually validated in steady-state operation. However, the heat for the steam generation may not be available for the operation of the SOE when inexpensive power is offered (e.g. off-grid peak, photovoltaics or wind). Thus, the challenge is to optimize the coupling of the SOE with two intermittent sources: non-programmable renewable electricity and high-temperature solar heat from Concentrating Solar (CS) systems with Thermal Energy Storage (TES) to supply solar heat when power is made available.
In PROMETEO a fully integrated optimized system will be developed, where the SOE combined with the TES and ancillary components will efficiently convert intermittent heat & power sources to hydrogen. The design will satisfy different criteria: end-users’ needs, sustainability aspects, regulatory & safety concerns, scale-up and engineering issues.
The players of the value-chain will play key roles in the partnership created around the project: from developers and research organizations, to the electrolyzer supplier, system integrator/engineering and end-users.
A fully-equipped modular prototype with at least 25 kWe SOE (about 15 kg/day hydrogen production) and TES (for 24 hours operation) will be designed, built, connected to representative external power/heat sources and validated in real context (TRL 5). Particular attention will be given to partial load operation, transients and hot stand-by periods.
Industrial end-users will lead to techno-economic & sustainability studies to apply the technology upscaled (up to 100 MW) in on-grid & off-grid scenarios for different end-uses: utility for grid balancing, power-to-gas, and hydrogen as feedstock for the fertilizer & chemical industry.
