As energy storage demand accelerates across Europe, securing reliable battery supply is becoming a critical challenge. With policy pushing localisation and demand outpacing domestic capacity, questions remain around how supply chains will keep up. - How is demand for energy storage evolving across Europe ' and what does this mean for battery supply? - What are the key supply risks in ESS today ' from cell availability to system integration? - How will policy measures such as the Industrial Accelerator Act (IAA) impact sourcing and localisation? - Is Europe in a position to meet local content requirements ' or will supply continue to rely on imports? - What role could alternative supply hubs, such as Morocco, play in supporting Europe's ESS build-out? - How is ESS demand shaping the role of different chemistries ' particularly LFP and emerging alternatives? - Can sodium-ion become a cost-competitive option for energy storage at scale? - What does it take to de-risk ESS projects ' from supply and technology to financing?
