  • Project planning: A clear 'go/no-go' milestone is required before the demonstration phase. This milestone necessitates the delivery of detailed engineering plans, a comprehensive techno-economic assessment, and all required permits for the demonstrator. A clear pathway and timeline for obtaining permits must be presented in the proposal.

Evaluation Criteria

Award Criteria and Prioritization
  • General criteria: Award criteria, scoring, and thresholds are described in 'Annex D of the Work Programme General Annexes'.
  • Balanced portfolio consideration: Grants will be awarded not solely based on ranking, but with a specific aim to fund at least one highly-ranked proposal within concentrated solar power (CSP) and at least one within solar thermal heat and/or cold. This condition can also be met if a single funded proposal addresses both areas, provided all proposals meet the required thresholds and budget is available.
Expected Outcomes
  • Economic impact: Significant reduction of Levelised Cost of Heat Storage (LCOHS) and/or Levelised Cost of Energy (LCOE).
  • Market readiness: Successful demonstration and de-risking of thermal energy storage solutions that enhance the dispatchability of solar thermal plants/systems, thereby improving technology providers' access to financing due to better understanding of bankability.
  • Grid integration: Providing electricity grid operators with reliable options to manage the increasing share of variable-output renewables and reduce curtailments.
  • Strategic alignment: Supporting and facilitating the execution of the solar thermal implementation plan of the Strategic Energy Technology Plan (SET Plan) and the solar energy joint research and innovation agenda.
Project Quality and Impact
  • Innovation: Proposed solutions must offer substantial improvements in performance, cost-effectiveness, and life span over existing technologies.
  • Sustainability: Assessment of the proposed solutions' environmental and socio-economic sustainability is required.
  • Safety standards: Consideration of the Commission initiative for Safe and Sustainable by Design (SSbD) as a reference for assessing chemical and material safety and sustainability.
  • Exploitation potential: Plans for exploitation and dissemination of results must include a strong business case and a sound exploitation strategy. This includes preliminary plans for scalability, commercialisation, and deployment, indicating potential funding sources (e.g., the Innovation Fund).

Compliance & Special Requirements

Regulatory & Ethical Compliance
  • Regulatory compliance: All applicable regulatory requirements are to be met, as described in 'Annex B of the Work Programme General Annexes'.
  • Data protection and privacy: General Horizon Europe rules apply.
  • Environmental compliance: Assessment of the environmental sustainability of the proposed solutions is required.
  • Ethical standards: Projects must adhere to ethical standards, likely detailed in the general Horizon Europe Work Programme Annexes.
  • Safety standards: Consideration of the Commission's Safe and Sustainable by Design (SSbD) framework for assessing chemicals and materials is expected as a reference.
Project Implementation & Risk Management
  • Permit acquisition: A clear and convincing pathway and timeline for obtaining all necessary permits for the demonstrator must be presented.
  • Go/No-Go Milestone: Projects must include a clear 'go/no-go' milestone before entering the demonstration phase, based on the completion of detailed engineering plans, techno-economic assessment, and permit acquisition.
  • Risk management: Implied through the requirement for detailed planning and assessment, particularly for the demonstration phase.
Intellectual Property & Exploitation
  • Exploitation strategy: A strong business case and sound exploitation strategy are required, including preliminary plans for scalability, commercialisation, and deployment of results.
  • Funding sources: Exploitation plans should indicate possible future funding sources, notably the Innovation Fund.
Cross-Cutting Considerations
  • Strategic priorities: Projects are expected to address cross-cutting priorities such as AI, Digital Agenda, and RePowerEU.
  • Balanced portfolio: The evaluation process will ensure a balanced portfolio by prioritizing at least one project in concentrated solar power (CSP) and one in solar thermal heat and/or cold among funded proposals.
