Descripción del proyecto
Más electricidad y calor de origen solar renovable para una producción eficiente de hidrógeno ecológico
La electrólisis de óxido sólido a alta temperatura puede servir para producir hidrógeno ecológico sin emisiones y satisfacer las necesidades de hidrógeno de las aplicaciones industriales. Es una opción especialmente sostenible cuando se combina con fuentes de energía renovables. Sin embargo, esas fuentes son intermitentes y a menudo incapaces de suministrar las altas temperaturas necesarias para generar vapor durante el proceso de electrólisis. El proyecto PROMETEO, financiado con fondos europeos, optimizará el acoplamiento de electrólisis de óxido sólido (el generador de hidrógeno) con calor renovable intermitente y electricidad generada con energía solar mediante un sistema de gestión de la energía térmica (TEMS, por sus siglas en inglés). El TEMS garantizará que el calor se mantiene a una temperatura suficientemente alta como para impulsar la electrólisis de óxido sólido con un bajo coste y una alta eficacia. El prototipo de PROMETEO evaluará tres aplicaciones industriales como usuarios finales.
Objetivo
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.
