Objectives

The overall objective of GH-Safe is to design, model and assess a green hydrogen energy chain suited to the constraints of isolated communities.

• Optimise dynamic hydrogen production: investigate PEM electrolysers supplied by intermittent photovoltaic generation and define suitable operating strategies.
• Develop safe and efficient storage: assess Liquid Organic Hydrogen Carriers, associated catalytic processes, thermal integration, and the energy consumed during hydrogen storage and release.
• Integrate the energy chain: combine photovoltaic generation, electrolysis, hydrogen storage and hydrogen-to-electricity conversion within a coherent system.
• Size the solution: develop numerical models that adapt components and operating strategies to available resources and energy demand.
• Assess feasibility: analyse technical performance, costs, life-cycle environmental impacts and the social acceptability of the solution.
• Prepare future developments: formulate recommendations for progressing towards demonstrators with a higher technology readiness level.

ENERGY-Lab’s specific contribution covers solar and climate resources, climate-energy databases, photovoltaic simulations, energy-system sizing, and participation in techno-economic and environmental assessments.
