HORIZON-CL5-2026-03-D3–21: Novel solutions for off-grid storage of renewable energy for critical infrastructures

4 Million EUR/project
“The topic aims to develop novel, cost-efficient off-grid energy storage solutions for renewable energy, tailored for critical infrastructures such as hospitals, transport hubs, data centres, and utilities.”
Further information: https://ec.europa.eu/info/funding-tenders/opportunities/docs/2021–2027/horizon/wp-call/2026–2027/wp-8-climate-energy-and-mobility_horizon-2026-2027_en.pdf#page=163

Deadline: 31 March and 20 October 2026 (two stage)

HORIZON-CL5-2026-04-Two-Stage-D3–02: Next generation of renewable energy technologies

4 Million EUR/project
“Selected projects are expected to consider the drivers behind social acceptance and trust- building of the technological solution and assess the best way to promote local involvement as part of ensuring a just transition (gender, cultural and socio-economic factors should be accounted for). An analysis of policy approaches that are encompassing (policy mixes), adaptive (policy learning) and context sensitive (working for different places, levels and/or sectors) should also be performed in order to support the deployment of the future new technology.”

Deadline: 14 April and 8 October 2026 (two stage)

HORIZON-CL5-2026-06-Two-Stage-D5–19: Non-exhaust emissions in road and railway transport

3.5–4 Million EUR/project
“Quantitative data on the magnitude of non-exhaust emissions are fragmented and highly uncertain, particularly when compared to data for exhaust emissions. Emissions vary widely according to brake, tyre and road surface material, and with driving style. Further research efforts are necessary to increase the understanding of these particles, their creation, ageing and dispersion in the environment.”

Deadline: 15 April 2026

HORIZON-CL5-2026-07-D1–03: Economics of climate change and cost of inaction

4 Million EUR/project
“Actions should develop and enhance models, methods, and tools to improve the understanding of future socio-economic costs of climate inaction (for the purpose of this topic defined as insufficient, or delayed action), advancing novel approaches and frameworks to address the limitations in existing methodologies, integrating latest scientific evidence, diverse data sources and applicable to various conditions and contexts.”

HORIZON-CL5-2026-07-D1–04: Fighting disinformation and effectively communicating on climate change

4–5 Million EUR/project
“Actions are expected to advance the understanding of the sources, channels, types, and influence of misinformation and disinformation on the public perception and assimilation of climate change-related information.”
Further information: https://ec.europa.eu/info/funding-tenders/opportunities/docs/2021–2027/horizon/wp-call/2026–2027/wp-8-climate-energy-and-mobility_horizon-2026-2027_en.pdf#page=59

Deadline: 4 March 2027

HORIZON-CL5-2027-01-D1–09: Assessing the performance of policy instruments to inform climate change mitigation action

3 Million EUR/project
“Actions should go beyond traditional decomposition analysis and employ state-of-the-art econometric techniques. They are expected to improve existing methodologies or develop new ones to help distinguish the contribution of GHG emission reductions between policy-driven effects and external drivers. Machine learning and other digital tools and methods could be applied to fill information gaps and gain additional insights.”
Further information: https://ec.europa.eu/info/funding-tenders/opportunities/docs/2021–2027/horizon/wp-call/2026–2027/wp-8-climate-energy-and-mobility_horizon-2026-2027_en.pdf#=70

HORIZON-CL5-2027-01-D1–10: Understanding and avoiding maladaptation to climate change

5–6 Million EUR/project
“The analysis should be comprehensive and consider an integrated and systemic approach (including insights from Social Sciences and Humanities (SSH) to maladaptation causes and drivers of very diverse nature, such as trade-offs and feedbacks with other priorities and sectors, poor decision making and implementation practices and the inherent uncertainty and other features of the adaptation process).”

HORIZON-CL5-2027-01-D1–13: Next generation scenarios for informing climate and sustainability transitions

4 Million EUR/project
“Actions should promote transdisciplinary collaboration and co-design with stakeholders to integrate diverse perspectives and needs They should develop and test new approaches, including communication, to improve uptake of results by various audiences. The topic therefore requires inclusion of relevant SSH expertise, to produce meaningful and significant effects to enhance the societal impact of related research activities.”
