Andalusian Green Hydrogen Valley Project Development
Moeve
I am an Industrial Engineer from the University of Navarra with a strong background in developing large-scale renewable energy projects, particularly in green hydrogen and e-fuels. Currently, I am part of the Project Development team at Moeve, where I contribute to the Andalusian Hydrogen Valley, Spain’s largest green hydrogen and e-fuels initiative. My work focuses on strategic project planning, stakeholder engagement, and driving innovative solutions that accelerate the energy transition and industrial decarbonization.

As renewable energy expands beyond centralised grids, decentralised hydrogen production emerges as a strategic solution for regional energy autonomy, industrial decarbonisation, and transport applications. This paper presents a systems-level study on the implementation of modular electrolysis units powered by distributed renewable energy sources for green hydrogen production.
The research focuses on the technical design, operation, and infrastructure integration of decentralised electrolysis units, particularly PEM-based systems. The Water and Oxygen Management System (WOMS) is analysed in detail, including failure modes and operational optimisation through digital twin modelling. Flexibility is assessed in terms of dynamic load-following, renewable variability, and integration with energy storage systems.
Infrastructure challenges such as water supply, grid interconnection, compression, and hydrogen storage are mapped across multiple deployment environments—industrial parks, rural communities, and island systems. Geospatial and economic modelling is used to identify optimal node placement, delivery logistics, and scalability scenarios. A modular design approach is highlighted to ensure compatibility with evolving demand and technological maturity.
The study also includes a techno-economic sensitivity analysis of system CAPEX, electrolyser utilisation rate, renewable electricity pricing, and policy incentives. Case studies from Europe and MENA regions are incorporated to compare regulatory frameworks and support mechanisms.
Findings indicate that decentralised modular hydrogen production can enhance resilience, reduce transmission losses, and provide flexibility services to local energy systems. Moreover, digital tools for performance monitoring, predictive maintenance, and system control are crucial for reliability and efficiency. The paper concludes with recommendations for harmonised standards, digital integration, and targeted investment to accelerate deployment.
