Building the Foundations for Second-Life Batteries: CORVUS in BIG LEAP

Interview

CORVUS Energy brings its deep expertise in maritime battery systems to BIG LEAP, leading the definition of technical requirements for first- and second-life batteries. As coordinator of early strategic actions, CORVUS ensures that the project starts with a solid foundation, mapping use cases, guiding dismantling processes, and shaping the path toward scalable, interoperable energy storage solutions.

What is the main role of CORVUS in the BIG LEAP project?

CORVUS leads the definition of technical and operational requirements for both first-life and second-life battery systems. This includes mapping battery configurations based on chemistry, lifetime, and safety standards, and identifying suitable use cases for second-life applications—especially in maritime and stationary storage contexts. CORVUS also coordinates the dismantling and testing of aged batteries, helping to evaluate their health and potential for reuse. These early actions are essential to ensure that the project’s demonstrators are built on reliable, well-characterized components.

Beyond its leadership in requirements and dismantling, CORVUS contributes to the design of modular energy storage systems, supports the development of interoperable BMS strategies, and plays a key role in data collection for algorithm development. It also helps define sustainability goals and leads market analysis for waterborne applications. In short, CORVUS is shaping both the technical backbone and the strategic direction of BIG LEAP.

What are the main challenges CORVUS may face in the project?

One of the key challenges for CORVUS is developing standardized methods to dismantle and evaluate aged batteries. Each module has its own chemistry, history, and performance profile, so creating reliable procedures to assess their health and potential for reuse is complex. CORVUS must ensure that these methods are not only technically sound but also scalable and compatible with different applications—from maritime systems to stationary storage.

 

Another challenge lies in managing and harmonizing data across multiple battery systems and BMS models. CORVUS supports the development of predictive algorithms for battery health and lifetime, which requires integrating diverse datasets into a unified structure. Ensuring that this data is accurate and usable is critical for the success of BIG LEAP’s digital layer. At the same time, CORVUS leads the market analysis for waterborne applications, translating technical innovation into viable business models. Balancing technical precision, data integrity, and strategic foresight is essential to making second-life batteries a reality at industrial scale.

Rebelion 

REBELION is a project funded by the European Union with the objective of addressing the waste management challenges posed by lithium-ion batteries (LIBs) used in electric mobility. After their second life, recycling represents not only the most environmentally friendly alternative for batteries, but also a natural and economic resource since the raw materials contained in LIBs can be valorised for further manufacturing. This is particularly relevant in the EU, which is a net importer of critical raw materials while up to 40% of the EVs are sold in Europe. Therefore, a solid recycling industry can become the European mining equivalent, promoting both environmental and economic benefits to the EU region.

TradeRES 

The TradeRES project will develop and test innovative electricity market designs that can meet society’s needs of a (near) 100% renewable power system. A long-term sustainable market design needs to provide efficient operational and investment incentives for an electricity system that is characterized by a high share of variable renewable energy sources (VREs) by increasing integration with other energy sectors, e.g. transport and hydrogen, and by increasing participation of flexible electricity demand from households to industrial consumers. Furthermore, this market design needs to provide security of supply by ensuring sufficient controllable electricity generation capacity whilst being economically efficient. Finally, despite the variability of solar and wind energy, the market risks should be allocated in an efficient and socially accepted way. This should also safeguard that consumers are not exposed to extreme swings in their energy expenses. In this sense, this project aims at finding market designs that are economically efficient in the above setting. To achieve these goals the project will use an iterative methodology and involve the key players from the energy sector in order to achieve and test the most suitable market designs. The project TradeRES – Tools for the Design and Modelling of New Markets and Negotiation Mechanisms for a ~100% Renewable European Power System, is funded by the EU framework programme for research and innovation Horizon 2020 under the call H2020-LC-SC3-2019-ES-SCC.
