The CLEAN initiative is the national powerful Danish green cluster organisation that incorporates the former LEAN Energy Cluster (LEC) and Copenhagen Cleantech Cluster (CCC) under one brand to support Cleantech business development in the field of energy and climate technology. CLEAN aims to create the best possible conditions for the development of clean and energy-efficient solutions. Danish and international companies need even more intensive support to promote innovation, and to create new markets, jobs and economic development within the cleantech sector. We work to promote energy efficiency and cleantech based on sustainability throughout the value chain of the entire energy system. Our focus is therefore on developing technologies and solutions in the fields of energy efficiency and intelligent energy systems. The innovation cluster has more than 350 stakeholders and supports its members to develop solutions and technologies within the areas of energy refurbishment and clean intelligent energy systems.
