--- ## Description The Clean Energy Transition Co-Funded Partnership (CET Partnership) is a Horizon Europe initiative designed to accelerate the EU's clean energy transition. Building on national and regional research and innovation (R&I) funding programmes, it aims to empower the energy transition and support the EU’s goal of becoming the first climate-neutral continent by 2050. The partnership fosters innovation ecosystems at local, regional, and transnational levels, implements joint calls, and aligns priorities to maximize the impact and uptake of clean energy technologies. The CET Partnership is guided by a Strategic Research and Innovation Agenda (SRIA), developed collaboratively with stakeholders across Europe. The partnership addresses new geopolitical and energy market realities, aiming to reinforce R&I investments, accelerate the transition, and increase energy independence. Activities include joint funding calls, knowledge exchange, upscaling, replication, and market diffusion of innovative solutions. --- ## Due Dates - September 2026 (anticipated/projected): Full application submission deadline *All dates are projected based on the annual cycle;
