Capattery ion gradient based bioelectrochemical energy storage system

Objective

CAPION will develop a novel ion-gradient-based bioelectrochemical energy storage system, leveraging biologically inspired components to overcome the limitations of conventional batteries and supercapacitors. As society moves toward increased electrification, miniaturisation and sustainability, the demand for low-voltage, compact, and environmentally neutral energy solutions is growing rapidly, particularly in healthcare, embedded electronics and autonomous sensing applications. Existing energy storage technologies, however, rely on redox chemistry or physical adsorption, which limits their stability, scalability and integration in sensitive or confined environments. CAPION addresses this bottleneck by developing a biologically based energy system that stores and supplies energy using stable ion gradients. The project builds on the PI’s ERC Advanced Grant Energion, which demonstrated the feasibility of vesicle-based energy generation using membrane proteins and bioinspired architectures. CAPION will validate the integration of this system into a self-contained energy module that can power a representative electronic device continuously for at least one month, without external recharging nor self-discharging. With its unique mechanism and sustainable design, CAPION holds strong potential to unlock new use cases where conventional energy storage is unsuitable.

Programme(s)

Multi-annual funding programmes that define the EU’s priorities for research and innovation.

Topic(s)

Calls for proposals are divided into topics. A topic defines a specific subject or area for which applicants can submit proposals. The description of a topic comprises its specific scope and the expected impact of the funded project.

Funding Scheme

Funding scheme (or “Type of Action”) inside a programme with common features. It specifies: the scope of what is funded; the reimbursement rate; specific evaluation criteria to qualify for funding; and the use of simplified forms of costs like lump sums.

HORIZON-ERC-POC - HORIZON ERC Proof of Concept Grants

Host institution

UNIVERSITE GRENOBLE ALPES
Net EU contribution

Net EU financial contribution. The sum of money that the participant receives, deducted by the EU contribution to its linked third party. It considers the distribution of the EU financial contribution between direct beneficiaries of the project and other types of participants, like third-party participants.
