Horizon Europe’s 2025 draft Cluster 5 Energy Work Programme – any call topic of interest to you?
4th March 2025 at 3:56 pm
Horizon Europe: research & innovation for a sustainable future
Cluster 5 of Horizon Europe is dedicated to funding research and innovation projects that contribute to the European Green Deal, which stands as one of the European Union’s key policy objectives. In the 2025 draft Work Programme, the cluster will have a total budget of 1.4 billion euros to support initiatives focused on combating the climate crisis, advancing the transition to green energy, and transforming mobility systems across Europe. This funding aims to drive significant progress in sustainable energy supply, enhance climate resilience, and foster innovative solutions to some of the most pressing challenges in the mobility sector.

Unlocking the future: Draft insights on the Horizon Europe 2025 Work Programme
The draft Cluster 5 Work Programme for 2025 is now available online, providing an opportunity to begin planning resources and assembling consortia for successful submissions later this year. While this is still a preliminary draft and changes are likely, reviewing the draft Work Programme now will offer valuable insights and a strategic edge in shaping strong, competitive proposals well ahead of the official call launches.
The call topics in the 2025 draft Work Programme are organised around five Destinations, addressing critical priorities in mobility, energy, and climate research and innovation. Notably, the deadlines for these call topics are clustered closely in September, making early preparation essential and we strongly recommend starting resource planning and consortium formation well in advance. Additional call topics with deadlines extending into early 2026 are not yet included in our infographics but will be updated in due course.
