Description
This topic is a continuation of the Clean Energy Transition Co-fund partnership (CET Partnership) and constitutes the EU contribution for the period 2025-2027.
The third instalment of the partnership will contribute to the expected outcomes specified in topic HORIZON-CL5-2021-D3-01-04: Clean Energy Transition, for continuation and development of new activities.
The partnership is expected to contribute to all of the following expected outcomes:
- Increased directionality of clean energy transition research and innovation in EU and Associated Countries in line with the SET Plan thanks to a shared pan-European vision on the goal and direction of required system transformation processes, adapted to regional needs and availability of renewable energy resources;
- Evidence based energy and climate policy formulation;
- A wider systemic transition and energy supply required for a climate neutral economy in all sectors of society; enabling the transition of the built environment, transport, industry and other sectors to clean, low carbon energy;
- An innovation ecosystem for Europe's transition to clean energy and contribution to a resource and energy efficient system, both from an ecological and economic standpoint;
- A building block to a zero-emission energy system for the decarbonisation of transport, buildings, industry, agriculture in the specific European environment;
- Increased engagement of consumers and prosumers as well as fair and appropriate demand-response mechanisms integrated in the energy system;
- An energy system that meets the needs of different parts of society, in different geographical locations (urban and rural) and different groups.
The Clean Energy Transition co-funded Partnership (CET Partnership) is a transnational initiative on joint R&I programming to boost and accelerate the energy transition, building upon regional and national R&I funding programmes.
It aims at empowering the energy transition and contributing to the EU goal of becoming the first climate-neutral continent by 2050, by pooling national and regional R&I funding for a broad variety of technologies and system solutions required to achieve the transition. It will foster innovation ecosystems from the very local and regional level, up to the transnational European level, thus overcoming a fragmented European landscape. The CET Partnership enables national and regional R&I programme owners and managers from Member States and Associated Countries to align their priorities and implement annual joint calls from 2022 to 2027. The Partnership also organises joint accompanying activities to enable a dynamic learning process, extracts strategic knowledge and accelerates the upscaling, replication, and market diffusion of innovative solutions to maximise impact and foster the uptake of cost-effective clean energy technologies.
The common vision of the CET Partnership is already expressed in its Strategic Research and Innovation Agenda (SRIA) that has been co-created with the involved countries, the EU SET Plan Implementation Working Groups and ETIPs, all energy relevant ERA-Nets as well as the EERA joint programmes (over 500 editors, co-authors, commenters, and discussants). The SRIA articulates the common goal of (1) building a transnational transformative Joint Programming Platform, (2) developing and demonstrating technology and solutions for the transition of energy systems, and finally (3) building innovation ecosystems that support capacity building at all levels.
The objective of this action is to continue to provide support to the European Clean Energy Transition Co-fund Partnership identified in the Horizon Europe Strategic Plan 2021-2024 and first implemented under topic HORIZON-CL5-2021-D3-01-04, and in particular to fund additional activities (which may also be undertaken by additional partners) in view of its intended scope and duration, and in accordance with Article 24(2) of the Horizon Europe Regulation.
The new geopolitical and energy market realities require to drastically accelerate the clean energy transition and increase energy independence from unreliable suppliers and volatile fossil fuels. In support to the objectives of REPowerEU[1] it is expected that the partnership explores pathways and develops new actions to reinforce R&I investments (and utilisation of R&I results) accelerating the clean energy transition.
It is expected that the European Clean Energy Transition Co-Fund Partnership reinforces its ambition considering the revised SET Plan and continues the implementation of its SRIA by setting up joint calls in 2025, 2026 and 2027. In addition, the partnership is invited to setup joint calls without co-funding from the European Union.
The consortium that won the grant under topic HORIZON-CL5-2021-D3-01-04 is uniquely placed to submit a proposal to continue the envisioned partnership. With regards to the various activities already undertaken in previous years, no other consortium is able to continue the activities of the Partnership underway without a significant disruption of the ongoing activities.
While the grant under this topic should be attributed to a proposal submitted by the coordinator of the consortium funded under topic HORIZON-CL5-2021-D3-01-04, the consortium applying to the present topic may include additional partners and new activities, to be funded by the grant subject to an evaluation, which will take into account the existing context and the scope of the initial evaluation (as relevant), and related obligations enshrined in the grant agreement.

Destination & Scope
This Destination contributes directly to the Strategic Plan’s Key Strategic Orientations ‘Green transition’, ‘Digital transition’ and ‘A more resilient, competitive, inclusive and democratic Europe’.
In line with the Strategic Plan, the overall expected impact of this Destination is to contribute to the “Facilitating a clean and sustainable transition of the energy and transport sectors towards climate neutrality through cross-cutting solutions”.
This Destination covers thematic areas which are cross-cutting by nature and can provide key solutions for climate, energy and mobility applications. In line with the scope of cluster 5 such areas are batteries, hydrogen[1], communities and cities[2] and others. Although these areas are very distinct in terms of challenges, stakeholder communities and expected impacts, they have their cross-cutting nature as a unifying feature and are therefore grouped, if not addressed in other places of this work programme, under this Destination.
The main impacts to be generated by topics under this Destination are:
Batteries
- Increased competitiveness and strategic autonomy of EU Battery sector while maximising sustainability.
- Enhanced local and circular supply chains by reducing dependency on critical raw materials and upscaling processing capacity, also for recycled materials.
- An integrated European battery sector for high performance batteries, from design to manufacturing and all the way to end of life, reducing environmental impact.
- Improved resilience of EU energy system and facilitated integration of renewable energy sources through application of energy storage.
- Affordable and reliable batteries to boost the market penetration of Electric Vehicles and storage systems.
Cities and Communities
This topic is for continuation of the Driving Urban Transition (DUT) co-funded partnership to assist cities in their sustainability and climate neutrality transitions. The main impacts expected are:
- Strengthen EU as a role model for R&I and cooperation with international cities to align strategies and support the role of DUT as co-lead of the Urban Transitions Mission (UTM) under Mission Innovation (MI);
- Innovative urban governance, policy, and decision-making engaging citizens in the city making process;
- Integration of mobility and transport services, and their alignment with citizens’ needs;
- Climate-neutral, safe, inclusive and liveable neighbourhoods, towns, cities and urban services for the citizens’ well-being;
- Empowerment of all actors such as local authorities, business, civil society, knowledge institutions and citizens, being engaged in climate-neutrality transitions;
- Evidence-based implementation of the European Green Deal, the Urban Agenda for the EU and other urban-relevant policies and strategies.
[1] The bulk of activities are supported by the Institutional Partnership ‘Clean Hydrogen’.
[2] Communities and cities are mainly supported under the Mission on Climate-Neutral and Smart Cities, and through the co-funded Partnership ‘Driving Urban Transition’, implemented in this work programme as a grant to identified beneficiary.
