EIC Pathfinder Challenge: Mid to long term and systems integrated energy storage


This Challenge will support proposals from the following technologies and systems for stationary applications:

  • mid/long term energy storage for power systems, with technologies such as metal air or redox flow batteries, power to heat to power, chemical bonds, electrochemical/chemical/thermal hybrid solutions, integration of energy carriers and ‘storage to X’ strategies; concepts for centralised or decentralised applications at grid, industrial or district scale level are included, excluding micro and small scale or single building solutions;
  • mid/long term thermal energy storage (heating or cooling) at different temperature, such as building integrated and process systems integrated solutions, chemical looping or thermochemical storage, solar thermal energy harvesting and storage, combined storage of thermal and electrical energy as well as other energy vectors, storage systems integrated in cold chains and in industrial processes.

Detailed Call Description

The proposals, through non CRM-based systems integrated, life-cycle and circular thinking driven approaches, should develop a proof of concept (PoC) or lab-scale validated innovative mid to long term storage for centralised or decentralised applications ranging from large to mid scale and excluding small micro scale such as single building solutions. The proposed technologies include, but are not limited to, the following:

  • computational modelling and optimisation appliedto materials, components and control (i.e. charging/discharging) for storage;
  • heating/cooling storage through chemical and thermochemical technologies (adsorption, absorption, etc.) included their integration in buildings or industrial processes and for different temperature;
  • integration of energy storage systems into multi-vector energy grids and existing infrastructures, or into industrial processes for waste energy recovery and industrial symbiosis including concepts to ensable smart control;
  • systems-integrated thermal energy storage technologies for industrial and building applications (i.e. energy storage combined to solar and geothermal energy conversion, to pumped heat technologies, or to combined cooling, heat and power generation);
  • innovative concepts for hydrogen (H2) storage/compression combined with thermal energy management and storage.

Call Total Budget

€167 000 000

Financing percentage by EU or other bodies / Level of Subsidy or Loan

The total indicative budget of the present call is € 167 000 000 which is expected to be allocated in approximately equal shares across the challenges. The EIC considers proposals with an EU contribution of up to € 4 000 000 as appropriate.

The funding rate of this grant will be 100% of the eligible costs.

In addition to funding, projects will receive tailor-made access to a wide range of Business Acceleration Services.
