About the Thesis WorkAt the digital energy solutions department we develop Vattenfall’s digital assets that make tomorrow’s energy systems more efficient, flexible, and secure. From decentralized solutions like, batteries, e-mobility, and demand response to automation, secure IT/OT integration, and communications, our team turns innovation into real-world impact, accelerating the transition to fossil freedom.Energy storage, and particularly batteries, is becoming a cornerstone of the future energy landscape. Large-scale battery systems ranging from MW to hundreds of MW are now increasingly deployed alongside wind and solar farms, as well as behind the meter at customer sites. The costs of such installations have fallen dramatically, while rapid advancements in cell technologies and shifting market demands are creating new opportunities and challenges.This project aims to investigate:<ul><li>Which emerging battery chemistries and technologies (e.g., sodium-ion, solid-state, flow batteries) are most likely to address current limitations in cost, safety, lifespan, and material supply chains.</li><li>How new applications, such as grid-forming capabilities, provision of inertia, black start support, and sector coupling, can be enabled by upcoming battery technologies.</li><li>Which gaps exist between technical capabilities and current market design, particularly in how system services and flexibility are valued.</li><li>How business models can evolve to capture multiple value streams (e.g., combining grid services, self-consumption optimization, and resilience applications) and overcome today’s challenge of fragmented markets.</li><li>What role battery recycling, second-life applications, and circular economy practices can play in addressing sustainability gaps, an area still underexplored in current deployments.</li><li>How regulation, policy, and financing mechanisms might need to adapt to enable the scaling of novel storage technologies and business models.</li><li>The impact of supply chain dependencies and material criticality (e.g., lithium, cobalt) on market development, and how alternatives could shift global competitiveness.</li><li>To what extent simulation-based techno-economic models can help bridge the gap between promising lab-scale technologies and large-scale commercial adoption.</li></ul>The project will develop an analytical and simulation-based framework to assess business cases scenarios from different perspectives: technology readiness, cost-effectiveness, sustainability, and integration into future energy markets. This work will contribute to closing knowledge gaps on how next-generation batteries can move from innovation to real-world impact in the evolving energy system.This assignment is for 1 master student.
