Topic Description
Specific Challenge:

Optimised storage solutions for thermal and electric energy are needed in order to better synchronise the overall supply and demand, at residential, district and urban level. Efficient management of the peak loads would reduce the overall operational costs of the installations.

The main challenge is to demonstrate integrated thermal storage systems. The current mature technologies for thermal storage are mostly based on water. In order to increase the storage density, it is needed to further develop other systems such as the Thermochemical materials. The next wave of developments needs to be tackled in order to propose attractive equipment with a significant increase in storage capacity efficiency. The combination of renewable energy with storage is key to support the next generation of very low or plus energy houses. Such storage equipment will be exploited first and mostly in the residential buildings (existing and new ones).


Proposals should develop advanced solutions including all of the following elements:

  • Reach improved heat exchange in and between storage material and heat carrier as well as high performing storage reactor over time;
  • With respect to the entire storage system, advanced energy management is needed, Not only regarding the building needs but also taking in account external conditions such as grid constraints and price signals;
  • The overall system should be easy to maintain with low cost associated to this activity;
  • The demonstration should include several prototypes operating in three different climatic conditions (with compactness as a crucial boundary condition).

Proposals submitted under this topic should include actions designed to facilitate cooperation with other projects; to enhance user involvement; and to ensure the accessibility and reusability of data produced in the course of the project.

Activities should start at TRL 5 and achieve TRL 7 at the end of the project.

The Commission considers that proposals requesting a contribution from the EU between EUR 6 and 8 million would allow this specific challenge to be addressed appropriately. Nonetheless, this does not preclude submission and selection of proposals requesting other amounts.

Expected Impact:
  • Demonstrate solutions that have a stable, reliable long term performance in multi-cyclic seasonal and use of at least 20 years;
  • Deliver compact systems with the potential to fit in the limited space available in a single building in the existing housing stock or new buildings. The storage material volume per dwelling should not exceed 1 m3;
  • Solutions should demonstrate a potential to reduce the net energy consumption of a building by at least 25% and a have return-on-investment period below 10 years;
  • Use of high energy density storage materials allowing storage densities up to 10 times higher than water (based on overall system efficiency).

Relevant indicators and metrics, with baseline values, should be clearly stated in the proposal.

Cross-cutting Priorities:

Open Innovation
Clean Energy

Topic conditions and documents

1. Eligible countries: described in Annex A of the Work Programme.
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. See the information in the Online Manual.


2. Eligibility and admissibility conditions: described in Annex B and Annex C of the Work Programme. 


Proposal page limits and layout: please refer to Part B of the proposal template in the submission system below.


3. Evaluation:

  • Evaluation criteria, scoring and thresholds are described in Annex H of the Work Programme.  
  • Submission and evaluation processes are described in the Online Manual.

The following exceptions apply:

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.

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.

4. Indicative time for evaluation and grant agreements:

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


5. Proposal templates, evaluation forms and model grant agreements (MGA):

Innovation Action:

Specific provisions and funding rates
Standard proposal template
Standard evaluation form
General MGA - Multi-Beneficiary
Annotated Grant Agreement


6. Additional provisions:

Horizon 2020 budget flexibility
Classified information
Technology readiness levels (TRL) – where a topic description refers to TRL, these definitions apply

Members of consortium are required to conclude a consortium agreement, in principle prior to the signature of the grant agreement.

7. 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. See the Online Manual.

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.
