Topic Description
Specific Challenge:
  • The storage of thermal or electric energy needs optimised operational technical solutions in order to better manage and synchronise the overall supply and demand (at residential, district and urban level). Good management of the peak loads, especially stemming from an increase of renewable energy production, would reduce the overall energy consumption and the cost of operation of the installations.
  • Hybrid solutions are needed, inherently addressing the seamless conversion and integration of renewable electricity and heat, as to anticipate the future energy grid that will fully allow an exchange of different energy carriers. Such hybrid solutions form a next step in the electrification of the heat supply market.
  • To go beyond current state of the art on thermal storage (i.e. compact systems) for residential buildings, it is necessary to bring research activities in this field closer to pre-commercial stage, to demonstrate their technical and economic viability, and to optimise the operation of such hybrid solutions in view of combining them with the surplus of renewable electricity with low temperature heat and cooling demand.
  • In the EU, there are nowadays just a few examples of operationally integrated solutions for the optimal interaction in district networks, combining both electricity and heat/cooling energy supply and storage.
  • Efficient use of renewable energy in hybrid systems for the storage and generation of energy needs to be achieved.

Proposals should develop advanced innovative high-density hybrid energy storage devices, targeting the efficient use and further increase of renewable energy in the built environment, and demonstrating its value in terms of flexibility in the energy systems. They should address both electrical and thermal applications and able to reach a rapid release.

Such hybrid approaches encompass different aspects, which may be addressed separately or coherently:

  • high efficiency conversion and storage of surplus renewable electricity into heat;
  • multifunctional use in both heating and cooling applications at different temperature grades;
  • different time scales, e.g. in seasonal storage of high temperature solar heat and peak-shaving in lower temperature heat–pump applications.

Research and innovation activities should address:

  • electricity applications, where the technologies covered may include batteries, flywheels and capacitors suitable for applications in the power range of several tens of KW to 1 MW as well as other technologies related to storage of large-scale power needed for district areas.
  • thermal applications, where these hybrid solutions should develop the high efficiency conversion and storage of surplus renewable electricity into heat. The hybrid system should take into account the optimal ²integration of various potential heat storage media. Therefore, preference will be given to systems that exploit chemisorption or physisorption technologies (solid/ liquid) and/or latent heat (PCM). The innovation part of the project should include the possibility that energy systems may be connected, and of merging energy from different sources, e.g. renewable electricity combined preferably with electric storage and heat, industrial waste heat, heat grids, ground systems.

Proposals are expected to cover the various aspects of the overall system, such as design, storage materials, interfaces with various components and auxiliaries (heat exchangers, reactor etc) and include monitoring and control of the overall technologies/ components (BEMS).

Proposals should preferably include demonstration pilots for both residential and district connected buildings in at least two different climatic regions. They also need to integrate strategies for optimal interaction with the energy grid, and assess the value of this integration in view of flexibility in the energy system.

Activities are expected to focus on Technology Readiness Levels 4 to 6.

A significant participation of SMEs with R&D capacities is encouraged.

The Commission considers that proposals requesting a contribution from the EU between EUR 4 and 6 million would allow this specific challenge to be addressed appropriately. Nonetheless, this does not preclude submission and selection of proposals requiring other amounts.

Expected Impact:

For residential buildings which are not connected to District Heating and Cooling

  • Demonstration of the economic viability of the overall storage systems when operating in real conditions in residential buildings with a return of investment period of 9-10 years and proof of the potential for market penetration.
  • Technologies which are reliable and ensure a minimum of 20 years life time
  • Solutions compatible with existing building configurations – with compact systems using limited spaces in existing building (volume of storage limited to 3 m3).
  • Demonstration of an overall net energy reduction by 20 %.
  • Validated contribution to energy system flexibility


For residential buildings connected to District Heating and Cooling

  • Demonstration of the economic viability of the overall storage systems with return of investment of less than 20 years and proof of the potential for market penetration.
  • Technologies which are reliable and operating for a minimum of 30 years.
  • Provide compact systems (volume of storage limited to 1 m3).
  • Overall net energy gain of minimum 30%.

Proposals should include a business case and exploitation strategy, as outlined in the Introduction to the LEIT part of this Work Programme.

Cross-cutting Priorities:

Contractual Public-Private Partnerships (cPPPs)

Topic conditions and documents

Please read carefully all provisions below before the preparation of your application.

    described in part A of the General Annexes of the General Work Programme.

    Note also that a number of non-EU/non-Associated Countries that are not automatically eligible for funding have made specific provisions for making funding available for their participants in Horizon 2020 projects (follow the links to Australia, Brazil, Canada, China, Hong Kong &Macau, India, Japan, Republic of Korea, Mexico, Russia, Taiwan).
    described in part B and C of the General Annexes of the General Work Programme

    Proposal page limits and layout: Please refer to Part B of the standard proposal template.


    3.1  Evaluation criteria and procedure, scoring and threshold:
    The criteria, scoring and threshold are described in General Annex H of the work programme.
    The following exceptions apply:

    For single-stage and second-stage evaluations, the threshold for the criteria Excellence and Impact will be 4. The overall threshold, applying to the sum of the three individual scores, will be 12.

    The procedure for setting a priority order for proposals with the same score is given in General Annex H of the work programme. The following exceptions apply:

    Under 3 (a)
    Proposals are first ranked in separate lists according to the topics against which they were submitted (‘topic ranked lists’). When comparing ex aequo proposals from different topics, proposals having a higher position in their respective 'topic ranked list' will be considered to have a higher priority in the overall ranked list.

    Under 3 (b)
    For all topics and types of action, the prioritisation will be done first on the basis of the score for Impact, and then on that for Excellence.

    3.2 Submission and evaluation process: Guide to the submission and evaluation process


    Information on the outcome of single-stage evaluation: maximum 5 months from the deadline for submission.
    Signature of grant agreements: maximum 8 months from the deadline for submission.

    Classified information

    Technology readiness levels (TRL) – where a topic description refers to TRL, these definitions apply.

    Financial support to Third Parties – where a topic description foresees financial support to Third Parties, these provisions apply.


    Open access must be granted to all scientific publications resulting from Horizon 2020 actions.
    Where relevant, proposals should also provide information on how the participants will manage the research data generated and/or collected during the project, such as details on what types of data the project will generate, whether and how this data will be exploited or made accessible for verification and re-use, and how it will be curated and preserved.

    Open access to research data
    The Open Research Data Pilot has been extended to cover all Horizon 2020 topics for which the submission is opened on 26 July 2016 or later. Projects funded under this topic will therefore by default provide open access to the research data they generate, except if they decide to opt-out under the conditions described in annex L of the Work Programme. Projects can opt-out at any stage, that is both before and after the grant signature.

    Note that the evaluation phase proposals will not be evaluated more favourably because they plan to open or share their data, and will not be penalised for opting out.

    Open research data sharing applies to the data needed to validate the results presented in scientific publications. Additionally, projects can choose to make other data available open access and need to describe their approach in a Data Management Plan.

    - Projects need to create a Data Management Plan (DMP), except if they opt-out of making their research data open access. A first version of the DMP must be provided as an early deliverable within six months of the project and should be updated during the project as appropriate. The Commission already provides guidance documents, including a template for DMPs.

    - Eligibility of costs: costs related to data management and data sharing are eligible for reimbursement during the project duration.

    The legal requirements for projects participating in this pilot are in the article 29.3 of the Model Grant Agreement.
