Energy storage technologies are essential in low-carbon energy systems, but there is an imbalance in attention given to different types of storage. While short-duration storage is increasingly popular, the system value of long-duration storage is less well studied. This gap in knowledge limits the potential for fully optimizing energy systems. Multi-day energy storage, in particular, offers significant untapped benefits that could contribute to a more sustainable energy future.

This project quantifies these benefits using a validated, policy-relevant energy system model focused on Germany. The model integrates a range of storage solutions from short to long-duration storage, providing valuable insights for various scenarios. The outcome includes a comprehensive analysis of model KPIs and open-source, fully reproducible model code, which will support global research and inform policy decisions about the role of different energy storage technologies. The insights generated by this project will have a significant impact on the energy storage sector. By showcasing the value of long-duration storage, the project will help reshape energy policies, guiding future investments in storage technologies. It will also support the optimization of energy systems, contributing to a more resilient, sustainable, and decarbonized energy future globally.

Project Aims

Investigation of multi-day storage solutions, specifically 100h Iron-Air batteries and their system benefits in Germany 2035.

Explore the outcomes under different storylines and sensitivities such as different climate scenarios, a mandated German gas phase out or delayed transmission expansion.
